GERARDO GUZZO,

Petitioner-Appellant,

LUISA MARIA CRISTOFANO,

Respondent-Appellee.

_______________________________________________________________

Before: CABRANES, WESLEY, and LIVINGSTON, Circuit Judges.

The Hague Convention on the Civil Aspects of International Child Abduction (“Hague

Convention”), opened for signature Oct. 25, 1980, T.I.A.S. No. 11,670, and the International Child

Abduction Remedies Act (“ICARA”), 42 U.S.C. § 11601 et seq., generally require courts in the United

States to order children returned to their countries of “habitual residence” if those children have

been wrongfully removed to, or retained in, the United States. See Chafin v. Chafin, 133 S. Ct. 1017,

1021 (2013). This appeal asks whether a child was “habitually resident” in Italy within the meaning

of the Hague Convention and ICARA. As we explain, the Hague Convention uses the terms

“habitual residence” and “habitually resident” in a practical way, referring to the country where a
1
child usually or customarily lives. The term is not equivalent to the American legal concept of

“domicile,” which relies principally on intent. Nonetheless, when parents move temporarily to

another country, without agreeing to change the child’s principal place of residence, a petitioner

claiming that the new location has become the child’s “habitual residence” must show that the child

has “acclimated” to that country. Gitter v. Gitter, 396 F.3d 124, 134 (2d Cir. 2005). The petitioner in

this case failed to show that the parents agreed to settle in Italy, and he did not attempt to show that

the child had acclimated there. Accordingly, the United States District Court for the Southern

District of New York (Richard J. Sullivan, Judge) properly denied the petition for return of the child.

JOSÉ A. CABRANES, Circuit Judge:

The Hague Convention on the Civil Aspects of International Child Abduction (the “Hague

Convention” or “Convention”), opened for signature Oct. 25, 1980, T.I.A.S. No. 11,670, and the

International Child Abduction Remedies Act (“ICARA”), 42 U.S.C. § 11601 et seq.,1 generally require

courts in the United States to order children returned to their countries of “habitual residence” if

those children have been wrongfully removed to, or retained in, the United States. See Chafin v.

Chafin, 133 S. Ct. 1017, 1021 (2013). This appeal asks whether a child was “habitually resident” in

Italy within the meaning of the Hague Convention and ICARA. As we explain, the Hague

Convention uses the terms “habitual residence” and “habitually resident” in a practical way, referring

to the country where a child usually or customarily lives. The term is not equivalent to the American

1 Congress passed ICARA to “‘ensure greater uniformity in the [Hague] Convention’s implementation and

interpretation in the United States,’ and to ‘shorten the running-in period for effective U.S. implementation.’” Ozaltin v.

parents move temporarily to another country, without agreeing to change the child’s principal place

of residence, a petitioner claiming that the new location has become the child’s “habitual residence”

must show that the child has “acclimated” to that country.2 Gitter v. Gitter, 396 F.3d 124, 134 (2d

Cir. 2005). The petitioner in this case failed to show that the parents agreed to settle in Italy, and he

did not attempt to show that the child had acclimated there. Accordingly, the United States District

Court for the Southern District of New York (Richard J. Sullivan, Judge) properly denied the petition

for return of the child.

BACKGROUND

i.

Petitioner-appellant Gerardo Guzzo (the “Father”) is an Italian citizen and resident of

Scario, Italy, and respondent-appellee Luisa Maria Cristofano (the “Mother”) is a United States

citizen and resident of New York. They met in September 2005 onboard a flight from New York to

Italy and began visiting each other regularly and discussing the prospect of marriage. In January

2006, the Mother discovered that she was pregnant. She soon visited the Father in Italy, where they

resumed discussions about whether to get married in New York or Italy. The Father and Mother

eventually agreed to marry in New York while maintaining their respective residences in Italy and

New York.

In September 2006, their child was born. Based on the evidence presented at trial, the

District Court found that from 2006 to 2007 the parties maintained their “bi-continental marriage,”

each parent visiting the other on numerous occasions, and in December 2007 the parties agreed that

the Mother and the child would live primarily in Italy with the Father but return periodically to New

2 The Court of Appeals for the Ninth Circuit introduced the term “acclimatization”—later replicated by our Court

in Gitter v. Gitter, 396 F.3d 124, 134 (2d Cir. 2005)—as a short-hand reference for “the sense of being well-adjusted in
one’s present environment.” Mozes v. Mozes, 239 F.3d 1067, 1079 (9th Cir. 2001). We prefer the less cumbersome term
“acclimation” to denote the same concept.

York. During this time, however, the parents’ relationship became increasingly tumultuous. In

February 2009, the Mother took the child to New York and told the Father that she wanted a

separation.

Over the next few months, the parents negotiated a separation agreement (the “Separation

Agreement”), which the Mother signed in English on May 20, 2009, and which the Father signed in

Italian on June 10, 2009. As relevant here, the Separation Agreement provided that the parents

would “‘continue to live separate and apart,’” that the Mother would “‘have custody[ ] of the minor

child,’” and that the child would attend school at the Good Counsel Academy in White Plains, New

York. Guzzo v. Cristofano, No. 11 Civ. 7394 (RJS), 2011 WL 6934108, at *2 (S.D.N.Y. Dec. 30, 2011)

(quoting the Separation Agreement). The Separation Agreement also established a visitation

schedule, which provided that the child would spend at least two months each year in Italy with the

Father.

Soon after signing the Separation Agreement, the Mother returned to Italy with the child.

As the District Court explained, the Mother “testified that her trip to Italy was undertaken as an

attempt at reconciliation with [the Father], but that she was only willing to make the attempt because

she had the protection of the Separation Agreement.” Id. at *3. The Mother also testified that

“regardless of the reconciliation attempt, she never intended to have the child attend primary school

in Italy and that she always planned to live with the child in New York once he was in kindergarten.”

Id. With only intermittent vacations, including several trips to New York, the child continued to live

in Italy, where he attended nursery school.

In November 2010, the Mother took the child to New York with the intention of not

returning to Italy. The following month, the parents agreed to make another attempt at

reconciliation, and the Mother moved back to Italy in January 2011 with the child. The effort was

unsuccessful. In August 2011, the Mother returned with the child to New York, where they have

4
lived ever since. The Mother also initiated divorce proceedings in Westchester County, New York.

ii.

The Father initiated this action under the Hague Convention in October 2011, alleging that

the Mother had wrongfully removed the child from Italy in August 2011. The District Court held a

three-day bench trial in November 2011. The next month, the District Court denied the petition,

concluding that the Father had not proved by a preponderance of the evidence that Italy, rather than

the United States, was the child’s country of “habitual residence.” Guzzo, 2011 WL 6934108, at *4.

The District Court began by restating our two-part test for determining a child’s habitual

residence. Id. at *5 (citing Gitter, 396 F.3d at 134). Under that test, a court must first “inquire into

the shared intent of those entitled to fix the child’s residence . . . at the [last] time that their intent

was shared.” Gitter, 396 F.3d at 134. If a court concludes that the parents did not intend to change

a child’s habitual residence, it then must assess “whether the evidence unequivocally points to the

conclusion” that the child has acclimated to the new location, notwithstanding the parents’

intentions. Id. The District Court noted that the Father had rested his petition entirely on the first

prong, arguing that the parents had agreed to change the child’s habitual residence to Italy; he had

explicitly abandoned any argument that the child had acclimated to life in Italy. See Guzzo, 2011 WL

6934108, at *5 n.2.

Based on the evidence presented at trial, the District Court determined that the parents’

Settlement Agreement in 2009 exhibited their last shared intent regarding the child’s usual residence.

Although the Mother had moved to Italy with the child after signing the agreement, and had

attempted to reconcile with the Father, the Court found “no evidence that the attempted

reconciliation, in and of itself, altered the [Settlement] [A]greement in any way.” Id. at *6. The

Court also found the Father’s testimony that the parents reconciled in June 2009 and formed a new

shared opinion that the child would live in Italy to be “not credible.” Id. at *7. As the Court

5
explained:

[The Father] made no mention of the alleged conversations in which the parties
reached a new agreement about where the child should be educated in any of his pre-
trial affidavits, memoranda of law, or proposed findings of facts and conclusions of
law. Indeed, [the Father] has put forward no evidence of any kind to corroborate his
testimony on this issue, despite the abundance of e-mails and letters between the
parties that were produced. Put simply, the Court finds [the Father’s] assertion of a
new “mutually shared intent” to educate the child in Italy to be a wholesale
fabrication designed to meet the legal standard established by the Second Circuit in
Gitter.

Id. The Court further concluded that “[d]espite the parties’ apparently sincere attempts at

reconciliation, the evidence demonstrates that [the Mother] never contemplated spending her life in

Italy or having the child attend Italian schools following preschool.” Id.

With respect to the child’s attendance at nursery school in Italy, the Court found that the

Mother had “testified credibly that, regardless of the outcome of the attempted reconciliation, she

intended to send the child to kindergarten in New York.” Id. For instance, the Mother home-

schooled the child in English “in order to prepare him for school in the United States.” Id. She also

retained ties to New York, by keeping her property there, and by “continu[ing] to perform work for

New York clients and [to] collaborate with attorneys in New York.” Id. at *8. The Mother also

refused to register her marriage with Italian authorities, which would have enabled her to obtain

Italian public health insurance. And the child “did not have Italian medical insurance, but rather was

insured through Medicaid and received his primary medical treatment in the United States.” Id.

After reviewing the relevant case law, the Court concluded that “the evidence overwhelmingly

demonstrates that, following the execution of the Separation Agreement, the parties never shared an

intention to make Italy the child’s habitual residence.” Id. at *9. Accordingly, the District Court

held that the Father had not established that the child’s habitual residence was Italy, and denied the

petition for return of the child.

This appeal followed.

 DISCUSSION

A. Legal Framework

i.

“The Hague Convention on the Civil Aspects of International Child Abduction generally

requires courts in the United States to order children returned to their countries of habitual residence, if

the courts find that the children have been wrongfully removed to or retained in the United States.”

Chafin, 133 S. Ct. at 1021 (emphasis supplied). The question presented in this appeal is whether the

Father met his burden of showing that the “habitual residence” of the child was Italy.

“Habitual residence,” as one court has observed, “is the central—often outcome-

determinative—concept on which the entire [Hague Convention] system is founded.” Mozes v.

Mozes, 239 F.3d 1067, 1072 (9th Cir. 2001). Indeed, the terms “habitual residence” and “habitually

resident” are used throughout the Hague Convention, see Gitter, 396 F.3d at 130 & n.6 (listing uses),

and determining the child’s country of habitual residence is a threshold issue in nearly all Hague

Convention cases, because the laws of that country determine the custody rights recognized by the

Convention, see Hague Convention, art. 3.3

Despite the importance of the “habitual residence” concept, the drafters of the Hague

Convention deliberately left that term undefined. See Holder v. Holder, 392 F.3d 1009, 1015 (9th Cir.

3 Article 3 provides, in full:
The removal or the retention of a child is to be considered wrongful where—
a) it is in breach of rights of custody attributed to a person, an institution or any other body,
either jointly or alone, under the law of the State in which the child was habitually resident
immediately before the removal or retention; and
b) at the time of removal or retention those rights were actually exercised, either jointly or
alone, or would have been so exercised but for the removal or retention.
The rights of custody mentioned in sub-paragraph a) above, may arise in particular by operation of
law or by reason of a judicial or administrative decision, or by reason of an agreement having legal
effect under the law of that State.
Hague Convention, art. 3.

7
2004). The official Hague Conference reporter described the term as “a well-established concept in

the Hague Conference, which regards it as a question of pure fact, differing in that respect from

domicile.” Elisa Pérez-Vera, Explanatory Report: Hague Conference on Private International Law ¶ 66, in 3

ACTS AND DOCUMENTS OF THE FOURTEENTH SESSION 426, 445 (1982).4 Courts have widely

recognized that the term should therefore be interpreted “according to ‘the ordinary and natural

meaning of the two words it contains, as . . . decided by reference to all the circumstances of any

particular case.’” Koch v. Koch, 450 F.3d 703, 712 (7th Cir. 2006) (quoting Mozes, 239 F.3d at 1071

(alterations omitted)).

Understood in an ordinary and nontechnical way, a child’s “habitual residence” is simply the

place where he usually or customary lives.5 See, e.g., Rydder v. Rydder, 49 F.3d 369, 373 (8th Cir. 1995)

(noting “no real distinction between habitual and ordinary residence” (citing Friedrich v. Friedrich, 983

F.2d 1396, 1401 (6th Cir. 1993), in turn citing Re Bates, No. CA 122.89, High Court of Justice,

United Kingdom (1989))). “‘[I]n their natural and ordinary meaning[,] the words mean that the

person must be habitually and normally resident [in that country], apart from temporary or

occasional absences of long or short duration.’” Mozes, 239 F.3d at 1073 (quoting Shah v. Barnet

London Borough Council, [1983] 1 All E.R. 226, 233 (Eng. H.L.)); see also id. at 1073 n. 13. Or, put

another way, “we might say that if we observe someone centering his life around a particular

location during a given period, so that every time he goes away from it he also comes back, we will

call this his habitual residence.” Id. at 1073–74. Under the Hague Convention, a petitioner bears the

burden of establishing by a preponderance of the evidence a child’s habitual residence at the time of

4We have repeatedly observed that the Pérez-Vera Report is “an authoritative source for interpreting the
Convention’s provisions.” Ozaltin, 708 F.3d at 369–70 n.21 (quotation marks omitted).

5 See also BLACK’S LAW DICTIONARY 1423 (9th ed. 2009) (defining one’s “residence” as “[t]he place where one

actually lives, as distinguished from a domicile,” and one’s “habitual residence” as “[a] person’s customary place of
residence”).

the contested removal. See Mota v. Castillo, 692 F.3d 108, 112 (2d Cir. 2012) (citing 42 U.S.C.

§ 11603(e)(1)(A)).

Although the concept of “habitual residence” seems straightforward, the issue is often

disputed in Hague Convention cases, which tend to involve children with ties to more than one

country. See Gitter, 396 F.3d at 133. Given the Congressionally recognized “need for uniform

international interpretation of the Convention,” 42 U.S.C. § 11601(b)(3)(B), courts have articulated

guiding principles to provide for “intelligibility and consistency in [the] application” of this term,6

Mozes, 239 F.3d at 1072.

Determining a child’s habitual residence often becomes difficult when parents move a child

from one country to another, raising the question of which country is the “habitual residence” of the

child. In evaluating these cases, we have looked to the intent of the parents as a particularly

important factor in understanding the context of a child’s move to another country. As we have

explained:

Focusing on intentions gives contour to the objective, factual circumstances
surrounding the child’s presence in a given location. This approach allows an
observer to determine whether the child’s presence at a given location is intended to
be temporary, rather than permanent. For example, it allows an observer to
distinguish between a child who went away to summer camp for a temporary
duration and a child who moved permanently to a new location. In the case of the
6 One reason for interpreting the term “habitual residence” with predictability is to give parents “crucial
information” they might need in order to make informed decisions before traveling or temporarily moving with their
children. Mozes, 239 F.3d at 1072; see also Silverman v. Silverman, 338 F.3d 886, 896 (8th Cir. 2003) (en banc) (“[I]t is
imperative that parents be able to assess the status of the law on habitual residence and wrongful removal and
retention.”). Although parents cannot stipulate to habitual residency, see Barzilay v. Barzilay, 600 F.3d 912, 920 (8th Cir.
2010), courts have widely considered parental intent as one of the relevant factors, see, e.g., Mozes, 239 F.3d at 1073–81,
especially when young children are at issue, see, e.g., Larbie v. Larbie, 690 F.3d 295, 310–11 (5th Cir. 2012). Notably,
however, incorporating parental intent into the meaning of the term “habitual residence” is not the only way that parents
can obtain peace of mind before traveling or temporarily moving, and therefore the term need not bear the entire weight
of the Mozes Court’s insight regarding the importance of parental intent. In particular, the removal of a child from a
country of habitual residence is only “wrongful” within the meaning of the Hague Convention if it is done in breach of
rights of custody belonging to the other parent, see note 3, ante. Accordingly, if the removal is pursuant to a prior
agreement “having legal effect under the law of th[e] State [of habitual residence],” then the removal is not “wrongful.”
Id. at 307. As we recently explained, “if one parent has lawful authority to change the residence of the child and doing
so will not breach the other parent’s custody rights, that parent may remove the child without being subject to a return
remedy under the Hague Convention.” Ozaltin, 708 F.3d at 367. Under Article 13 of the Hague Convention, a return
order also is not required, inter alia, if the petitioner “consented to or subsequently acquiesced in the removal or
retention.” Hague Convention, art. 13(a).

9
 child away at summer camp, one would generally conclude that the child has not
acquired a new habitual residence . . . [because] “he already has an established
habitual residence elsewhere and his absence from it—even for an entire summer—
is no indication that he means to abandon it.”

Gitter, 396 F.3d at 132 (quoting Mozes, 239 F.3d at 1074). Accordingly, “we will presume that a

child’s habitual residence is consistent with the intentions of those entitled to fix the child’s

residence at the time those intentions were mutually shared.” Id. at 133.

At the same time, however, “parental intent cannot alone establish a child’s habitual

residence,” nor can it prevent a habitual residence from changing. Id. Instead, a child’s habitual

residence changes when the child becomes settled in another country, even if one or both of the

parents intend for the child to return to the original country of habitual residence. Id. at 133–34. As

we have explained:

“The question in these cases is not simply whether the child’s life in the new country
shows some minimal degree of settled purpose, but whether we can say with
confidence that the child’s relative attachments to the two countries have changed to
the point where requiring return to the original forum would now be tantamount to
taking the child out of the family and social environment in which its life has
developed.”

Id. at 134 (some internal quotation marks omitted) (quoting Mozes, 239 F.3d at 1081). In other

words, we ask: “[W]ould returning the children . . . be tantamount to sending them home?” Holder,

392 F.3d at 1019. Accordingly, although “[n]ormally the shared intent of the parents should control

the habitual residence of the child,” that intent is not controlling when “the evidence unequivocally

points to the conclusion that the child has [acclimated] to the new location.” Gitter, 396 F.3d at 134.

The Hague Convention, after all, “places at the head of its objectives the restoration of the status quo,

by means of the prompt return of children” to their home country. Gitter, 396 F.3d at 130 (internal

quotation marks omitted).

The two-step framework articulated in Mozes and followed by our Court in Gitter is flexible

enough to account for the varied circumstances of individual cases. See, e.g., Nicolson v. Pappalardo,

10
605 F.3d 100, 105 (1st Cir. 2010) (noting that the “habitual residence” inquiry does not amount to

“rigid” adherence to parental intent); Koch, 450 F.3d at 715–16 (explaining that the framework in

Mozes is “flexible” and “not so rigid”). When applying this framework, the age of the child and the

time spent in the respective countries can affect how much weight a court should place on parental

intent.7 For instance, parental intentions become less relevant the longer a child remains in the new

environment. In fact, once a child has “been living in one country . . . for a sufficiently long

period,” then “questions as to the purpose of the residence become irrelevant,” Gitter, 396 F.3d at

134 (quotation marks omitted). Accordingly, although it makes sense to “‘regard the intentions of

the parents as affecting the length of time necessary for a child to become habitually resident,

because the child’s knowledge of these intentions is likely to color its attitude toward the contacts it

is making,’” Ruiz v. Tenorio, 392 F.3d 1247, 1254 (11th Cir. 2004) (quoting Mozes, 239 F.3d at 1079–

80), courts must not forget that the core concern of “habitual residence” is where a child normally

or usually lives. Once a court “‘can say with confidence’” that the child has become settled into a

new environment, habitual residence in that country is established. Gitter, 396 F.3d at 134 (quoting

Mozes, 239 F.3d at 1081). In this way, the Gitter framework helps provide “intelligibility and

consistency” to the habitual residence inquiry, Mozes, 239 F.3d at 1072, but it is flexible enough to

recognize that the overall assessment of habitual residence is “not formulaic” but instead “is a fact-

intensive determination that necessarily varies with the circumstances of each case,”8 Whiting v.

Krassner, 391 F.3d 540, 546 (3d Cir. 2004).

7 When a child is younger, with less sense of the surrounding environment, courts place more emphasis on the

intentions of the parents. See, e.g., Holder, 392 F.3d at 1020–21 (“[I]t is practically impossible for a newborn child, who is
entirely dependent on its parents, to acclimatize independent of the immediate home environment of the parents.”);
Whiting v. Krassner, 391 F.3d 540, 550 (3d Cir. 2004) (“[W]hen the child involved is very young . . . acclimatization is not
nearly as important as the settled purpose and shared intent of the child’s parents in choosing a particular habitual
residence.”).

8 For a useful summary of foreign decisions reaching the same conclusion regarding the flexibility and fact-bound

nature of the habitual residence inquiry, see Tai Vivatvaraphol, Note, Back to Basics: Determining a Child’s Habitual Residence
in International Child Abduction Cases Under the Hague Convention, 77 FORDHAM L. REV. 3325, 3354–60 (2009).

11
 In sum, “[t]o determine which country is a child’s country of habitual residence under the

Hague Convention, we apply the two-part test set forth in Gitter v. Gitter.” Hofmann v. Sender, --- F.3d

----, 2013 WL 1955846, at *8 (2d Cir. May 14, 2013). We “begin an analysis of a child’s habitual

residence by considering the relevant intentions,” because “[f]ocusing on intentions gives contour to

the objective, factual circumstances surrounding the child’s presence in a given location.” Gitter, 396

F.3d at 132. We “presume that a child’s habitual residence is consistent with the intention of those

entitled to fix the child’s residence at the time those intentions were mutually shared.” Id. at 133.

This presumption can be overcome, however, if the evidence shows that a child is settled into (or,

“acclimated” to) the new environment—a burden that is more easily satisfied the longer a child has

lived in that country. When considering these two steps, the court must not lose sight of the fact

that the framework is designed simply to ascertain where a child usually or customarily lives.

ii.

On appeal, we review a district court’s factual findings for clear error and its legal

conclusions de novo. See Ozaltin, 708 F.3d at 368. The habitual residence inquiry is heavily fact

dependent, but whether the relevant facts satisfy the legal standard is a question of law that we

review de novo. See Gitter, 396 F.3d at 133 n.8; see also Ozaltin, 708 F.3d at 368 (“Legal conclusions

include interpretations of the Convention and applications of the appropriate legal standards to the

facts.”). Accordingly, “a determination of habitual residence under Article 3 of the Hague

Convention is a mixed question of law and fact, under which we review essentially factual questions

for clear error and the ultimate issue of habitual residence de novo.” In re B. Del C.S.B., 559 F.3d 999,

1008 (9th Cir. 2009) (internal quotation marks omitted); see also, e.g., Larbie v. Larbie, 690 F.3d 295,

312 (5th Cir. 2012) (citing Barzilay v. Barzilay, 600 F.3d 912, 916 (8th Cir. 2010)); Maxwell v. Maxwell,

588 F.3d 245, 250 (4th Cir. 2009). We conclude that a district court “clearly erred” only if a review

12
of the record “leave[s] us with ‘the definite and firm conviction that a mistake has been committed.’”

Hofmann, 2013 WL 1955846, at *8 (quoting Mota, 692 F.3d at 114).

B. Analysis

i.

The Father argues, in part, that we need not assess whether the child’s habitual residence

changed to Italy because the child was habitually resident in Italy throughout his whole life.

Accordingly, we begin by examining the District Court’s conclusion that the child was habitually

resident in the United States in 2009, at the time of the parents’ purported last shared intent

regarding the child’s residence.

Even assuming that the child was habitually resident in Italy prior to 2009, we conclude that

his habitual residence changed to the United States after the parties reached the Settlement

Agreement in May and June of 2009. As noted, habitual residence depends on a combination of

parental intent and physical presence, see, e.g., Mozes, 239 F.3d at 1079, but when a child is very

young, “the shared intent of the parents . . . [is] of paramount importance,” Whiting, 391 F.3d at 550.

We detect no clear error in the District Court’s finding that the Separation Agreement—signed by

the Mother and Father in May 2009 and June 2009, respectively—demonstrated the parents’ shared

intent for the child to live primarily in New York. Moreover, the child, who was then less than three

years old, had been living with the Mother in New York for several months. Because the child was

living in New York, and because the parents agreed that he would continue to reside in New York,

we agree that the child, in light of his age, was habitually resident in the United States at the time of

the Settlement Agreement.

The Father argues that the Settlement Agreement is invalid under Italian and New York law

and therefore cannot support the District Court’s finding of shared intent. We disagree.

“Regardless of whether the document is enforceable in [state] court, it is nevertheless clearly

probative of the parties ‘last shared intent’ for the purposes of determining habitual residence under

ICARA.” Guzzo, 2011 WL 6934108, at *6 n.3 (quoting Gitter, 396 F.3d at 134). Indeed, the Father

acknowledged at trial that when he signed the Agreement he understood (1) its terms; (2) that it

provided for the child’s residence in New York; and (3) that it would be legally binding, even though

he hoped to reconcile with the Mother. Id. at *5–6. Accordingly, we find no clear error in the

District Court’s finding regarding the parents’ shared intent that the child would reside in New York.

See Mozes, 239 F.3d at 1076 (noting that shared intent can exist “despite the fact that one parent may

have had qualms” about the agreement).

ii.

Having found no error in the District Court’s determination that the child was habitually

resident in the United States at the time of the Settlement Agreement in 2009, we now consider

whether the child became habitually resident in Italy following his return to that country in the

summer of 2009.

At the first step of the Gitter test, we ask whether the evidence offered at trial showed

“settled mutual intent from which . . . abandonment [of the prior habitual residence] can be

inferred.” Mozes, 239 F.3d at 1077. When considering this issue, “the court should look . . . at

actions as well as declarations.” Gitter, 396 F.3d at 134. “Clearly, this is one of those questions of

historical and narrative facts in which the findings of the district court are entitled to great

deference.” Mozes, 239 F.3d at 1077–78 (internal quotation marks omitted); see also Hofmann, 2013

WL 1955846, at *8 (“The last shared intent of the parents is a question of fact, and the district

court’s determination in that regard is reviewed for clear error and thus entitled to deference.”).

Having reviewed the record and the parties’ submissions, we conclude that the District

Court’s findings are “amply supported by the record, and there is nothing . . . leav[ing] us with ‘the

definite and firm conviction that a mistake has been committed.’” Hofmann, 2013 WL 1955846,

14
at *8 (quoting Mota, 692 F.3d at 114). Although the Mother agreed to the child’s return to Italy and

attendance at an Italian nursery school, the District Court found credible the Mother’s testimony

that her stay in Italy was temporary, and that she consistently intended to return to New York for

the child to begin kindergarten. Record evidence amply supports this conclusion. For instance, the

Mother and the child entered Italy on temporary tourist visas, and they registered for health care in

New York even though eligible for public health insurance in Italy. The District Court also credited

the Mother’s testimony that “her willingness to attempt a reconciliation in Italy was clearly premised

on the understanding that, should the reconciliation prove unsuccessful, the parties would continue

to abide by the terms of the agreement.” Guzzo, 2011 WL 6934108, at *9. Indeed, the Mother

returned to New York with the child in November 2010, with the stated expectation of staying

permanently in the United States, before she agreed to make another attempt at reconciliation with

the Father the following month. Accordingly, we do not disturb the District Court’s finding that the

parents never shared an intent for their child to abandon his prior habitual residence in the United

States.

iii.

The second step in the Gitter framework is to examine whether, notwithstanding a lack of

shared parental intent to change the child’s long-term residence, the child was nonetheless

sufficiently settled into (or, “acclimated” to) the new environment such that returning the child to

that environment would “be tantamount to sending [him] home.” Holder, 392 F.3d at 1019.

In this case, the five-year-old child lived mostly in Italy from soon after his birth in 2006

until his removal in 2011, and he regularly attended nursery school there. If it were properly raised

in this appeal, we might conclude that the child was “acclimated” to living in Italy—that is, we might

be able to “‘say with confidence’” that the child’s usual or customary place of residence was Italy,

notwithstanding any parental intentions to the contrary. Gitter, 396 F.3d at 134 (quoting Mozes, 239

15
F.3d at 1081). Compare, e.g., Shalit v. Coppe, 182 F.3d 1124, 1128 n.5 (9th Cir. 1999) (noting, without

deciding habitual residence, that “[t]hree years is certainly enough time for [the child] to be

considered ‘settled’ in Israel, regardless of [the mother’s] claimed intention to have him return

permanently to Alaska at some point in the future.”), with Hofman, 2013 WL 1955846, at *10 (no

acclimation to New York where child had lived there for “over a year” but had moved within the

state and had maintained “close ties to friends and caretakers in Canada”).

We need not address this issue, however, because the Father—represented by counsel in the

District Court and at the time of filing his opening appellate brief—did not preserve any argument

that the child was acclimated to Italy. See Guzzo, 2011 WL 6934108, at *5 n.2. “In our adversary

system, in both civil and criminal cases, in the first instance and on appeal, we follow the principle of

party presentation. That is, we rely on the parties to frame the issues for decision and assign to

courts the role of neutral arbiter of matters the parties present.” Greenlaw v. United States, 554 U.S.

237, 243 (2008). Although courts retain “the independent power to identify and apply the proper

construction of governing law,” Kamen v. Kemper Fin. Servs., Inc., 500 U.S. 90, 99 (1991), “our

adversary system is designed around the premise that the parties know what is best for them, and are

responsible for advancing the facts and arguments entitling them to relief,” Greenlaw, 554 U.S. at 244

(quotation marks omitted). Accordingly, the Father has waived any argument with respect to the

child’s “acclimation.” See, e.g., JP Morgan Chase Bank v. Altos Hornos de Mexico, S.A. de C.V., 412 F.3d

418, 428 (2d Cir. 2005) (arguments not presented in an appellant’s opening brief are waived).

CONCLUSION

To summarize:

1. Notwithstanding the argument of the petitioner (the Father) that the child has been

habitually resident in Italy since birth, we conclude that the child was habitually resident

in the United States in 2009. At that time, the two-year-old child was living in New York

16
 with the respondent (the Mother), and the parents agreed that he would continue to live

in the United States as his country of primary residence. Because parental intentions

regarding a child’s residence are of paramount importance at such a young age, and

because the child was already physically present in New York, we conclude that he was

habitually resident in the United States at the time of the parents’ Settlement Agreement

in 2009.

2. We also reject the Father’s argument that, even if the child was habitually resident in the

United States in 2009, he became habitually resident in Italy by the time of the contested

removal in August 2011. To assess this argument, we use a two-step framework for

evaluating whether a child’s “habitual residence” has changed. See Gitter v. Gitter, 396

F.3d 124 (2d Cir. 2005).

3. At the first step, we conclude that the District Court did not clearly err in finding that

the parents did not agree to change the child’s habitual residence from the United States.

4. The second step of the Gitter framework recognizes that the habitual residence inquiry is

flexible and does not place talismanic importance on parental intent, especially if the

child is old enough to appreciate his surroundings and has lived mostly in a single

country for an extended period. But we do not consider the second step of the Gitter

framework here because the Father has waived any reliance on that step.

Accordingly, because the District Court did not err regarding the first step of the Gitter test,

and because the petitioner has not preserved any argument regarding the second step, the judgment

dismissing the petition is AFFIRMED.
