I. Factual & Procedural Background
Barbara R. Duncan (Plaintiff) and John H. Duncan (Defendant) exchanged vows in two separate marriage ceremonies in North Carolina occurring twelve years apart. The first ceremony occurred on 15 October 1989 (the 1989 ceremony) and was presided over by Hawk Littlejohn, who held himself out to be a Cherokee medicine man1 and who was ordained as a minister by the Universal Life Church. In 2001, the parties’ estate planning attorney expressed his concern that the 1989 ceremony was not valid; and, accordingly, on 14 October 2001, Plaintiff and Defendant participated in a second ceremony at the First Presbyterian Church in Franklin, North Carolina (the 2001 ceremony).
In 2005, Plaintiff commenced this action seeking, inter alia, divorce, equitable distribution, alimony, and child support, alleging that the parties’ date of marriage was 15 October 1989, the date of the 1989 ceremony. Defendant filed responsive pleadings alleging, inter alia, that Hawk Littlejohn was not authorized under North Carolina law to perform a valid marriage ceremony; and, therefore, the parties’ *371date of marriage was 14 October 2001, the date of the 2001 ceremony. Accordingly, Defendant prayed the trial court to declare the 1989 ceremony invalid under North Carolina law.
Following a hearing, the trial court entered an order on 15 October 2007 (the 2007 order), concluding that the 1989 ceremony resulted in a valid marriage, that 15 October 1989 was “the date of marriage for all matters related to this Chapter 50 action” and that Defendant was estopped from contesting the validity of the 1989 ceremony.2
The trial court subsequently entered a number of additional orders and an equitable distribution judgment. Defendant appeals from the 2007 order and from a number of subsequently entered orders that he contends were affected by the 2007 order. Defendant also appeals from an order in which the trial court concluded that Plaintiff was “actually substantially dependent on [] Defendant for her support as of the date of separation” and a separate order in which the trial court held open the issue of whether to award attorney’s fees. Because the trial court left open the award of attorney’s fees, this Court, relying on our Supreme Court’s decision in Bumpers v. Cmty. Bank of N. Va., 364 N.C. 195, 695 S.E.2d 442 (2010), reasoned that Defendant’s appeal was interlocutory and dismissed it as untimely. Duncan v. Duncan,_N.C. App._,_, 732 S.E.2d 390, 392(2012).
Following discretionary review, our Supreme Court reversed, holding that an open request for attorney’s fees does not prevent a judgment on the merits from being final. Duncan v. Duncan, 366 N.C. 514, 742 S.E.2d 799 (2013). On remand from our Supreme Court, we now consider the merits of Defendant’s appeal.
II. Analysis
Defendant’s arguments on appeal are essentially that (1) the trial court erred in its 2007 order by determining that 15 October 1989 was the date of marriage for all matters related to this action; and (2) the trial court erred in its order in which it determined that Plaintiff was actually substantially dependent on Defendant for her support as of the date of separation. For the reasons stated below, we affirm the orders of the trial court.
*372A. Date of Marriage
Defendant argues that the 1989 ceremony was invalid; and, therefore, that the trial court erred in establishing the date of marriage based on the 1989 ceremony. As an initial matter, we hold that the issue regarding the validity of the 1989 ceremony was properly before the trial court. A marriage based on a ceremony in North Carolina not properly solemnized pursuant to the requirements of N.C. Gen. Stat. § 51-1 is voidable. See Fulton v. Vickery, 73 N.C. App. 382, 387, 326 S.E.2d 354, 358 (1985) (stating that a marriage performed by a minister of the Universal Life Church, not otherwise cured by N.C. Gen. Stat. § 51-1.1, was voidable). A party may apply to the court for a declaration that a voidable marriage “be declared void from the beginning!)]” N.C. Gen. Stat. § 50-4 (2013). However, avoidable marriage remains valid “for all civil purposes, until annulled by a competent tribunal in a direct proceeding." Geitner v. Townsend, 67 N.C. App. 159, 161, 312 S.E.2d 236, 238 (1984) (emphasis added).
Here, in his counterclaim, Defendant prays the court for an order “to declare [the 1989 ceremony] invalid[,]” which we believe is an application under N.C. Gen. Stat. § 50-4 for an order to “declare [a voidable] marriage void[,]” to the extent that the parties’ marriage is based on the 1989 ceremony. In other words, we believe that N.C. Gen. Stat. § 50-4 applies in this case even though Defendant does not seek to annul his marriage in toto — indeed, he admits that he and Plaintiff were lawfully married by virtue of their 2001 ceremony — but merely requests that the court declare the marriage invalid insomuch as it is based on the 1989 ceremony. Further, where one party sues for divorce, we believe that a counterclaim by the opposing party seeking an- order to declare the marriage invalid constitutes a “direct proceeding.” See Sprinkle v. N.C. Wildlife, 165 N.C. App. 721, 735, 600 S.E.2d 473, 482 (2004) (holding that “a counterclaim is in the nature of an independent proceeding], and] the filing of a counterclaim is to initiate a ‘civil action’ ”).
In this case, Defendant argues that the trial court erred by concluding that the 1989 ceremony was properly solemnized and by concluding that he “was judicially and equitably estopped from arguing” otherwise. For the reasons below, we believe that the trial court erred by concluding that the 1989 ceremony was properly solemnized and that Defendant was judicially estopped from contesting the validity of the 1989 ceremony; however, we do not believe that the trial court erred by concluding that Defendant was equitably estopped from contesting the validity of the 1989 ceremony. Therefore, we affirm the 2007 order to the extent that it concludes that Defendant is equitably estopped from challenging the *373validity of the 1989 ceremony and the date of marriage, for purposes of this action, to be 15 October 1989.
1. The 1989 Ceremony Was Voidable
Regarding the validity of the 1989 ceremony, Defendant does not argue that the ceremony did not take place. Rather, he contends that Hawk Littlejohn, who officiated the ceremony, was not authorized under the North Carolina law in effect at that time to solemnize a marriage.
Our Supreme Court has held that “[a] common law marriage or marriage by consent is not recognized by this State.” State v. Lynch, 301 N.C. 479, 487, 272 S.E.2d 349, 354 (1980). Rather, “[t]o constitute a valid marriage in this State, the requirements of G.S. 51-1 must be met.” Id. at 486, 272 S.E.2d at 353. The version of N.C. Gen. Stat. § 51-1 in effect in 1989 required, in pertinent part, that the parties “ ‘express their solemn intent to marry in the presence of (1) an ordained minister of any religious denomination; or (2) a minister authorized by his church; or (3) a magistrate.’ ”Pickard v. Pickard, 176 N.C. App. 193, 196, 625 S.E.2d 869, 872 (2006) (quoting Lynch, 301 N.C. at 487, 272 S.E.2d at 354).3 However, when it is established that a marriage ceremony has occurred - as is the case here - “the burden of showing that it was an invalid marriage rests on the party asserting its invalidity.” Overton v. Overton, 260 N.C. 139, 143, 132 S.E.2d 349, 352 (1963); see also Kearney v. Thomas, 225 N.C. 156, 163, 33 S.E.2d 871, 876 (1945) (stating that where there is “proof that a marriage ceremony took place, it will be presumed that it was legally performed and resulted in a valid marriage”). Accordingly, Defendant bore the burden of demonstrating that Hawk Littlejohn was not authorized under N.C. Gen. Stat. § 51-1 to solemnize the 1989 marriage ceremony. Based on the evidence that was before the trial court, we believe that Defendant met this high burden.
The record on appeal contains a statement of the evidence that was presented to the trial court, pursuant to Rule 9(c) of our Appellate Rules.4 With regard to the evidence presented before the trial court concerning Hawk Littlejohn’s authority to solemnize the 1989 ceremony, the Rule 9(c) statement sets forth that the parties made the court aware of the Supreme Court’s 1980 opinion in Lynch, supra-, and, further, that the *374parties stipulated that Hawk Littlejohn had performed the 1989 ceremony, that he was a minister ordained by the Universal Life Church, and that the relevant facts regarding the Universal Life Church as it applies in this case were essentially the same as described by the Supreme Court in Lynch.
In Lynch, our Supreme Court reversed a bigamy conviction of a defendant where one of his two marriages was solemnized before a Universal Life Church minister. Lynch, supra. The Court described the Universal Life Church as a church, headquartered in Modesto, California, with “no traditional doctrine” who “will ordain anyone, without question to his/her faith,” and that their ministers, which number over 7 million, have the authority to officiate at marriages but otherwise are “not require[d] to give up [their] membership with any other church to be a minister of the ULC, Inc.” Id. at 483, 272 S.E.2d at 351. The Court further described that the process of receiving certification as an ordained minister in. the Universal Life Church involved simply mailing one’s name, address and ten dollars to the Church’s California headquarters, and that the Church did not require any further proceedings or training as a requirement for ordination. Id. In reversing the bigamy conviction, the Court stated as follows:
A ceremony solemnized by a [layman] who bought for $10.00 a mail order certificate giving him ‘credentials of minister’ in the Universal Life Church, Inc. — whatever that is - is not a ceremony of marriage to be recognized for purposes of a bigamy prosecution in the State of North Carolina. The evidence does not establish — rather, it negates the fact — that [the “minister”] was authorized under the laws of this State to perform a marriage ceremony.
Id. at 488, 272 S.E.2d at 355 (emphasis added).
Since the record shows that Plaintiff stipulated that the “relevant facts” concerning the Universal Life Church and Hawk Littlejohn’s ordination as a minister therein were essentially the same as described by our Supreme Court in Lynch, and since our Supreme Court in Lynch stated that evidence that an individual was ordained by the Universal Life Church — as the Church is described in that case — “negates the fact that [the individual] was authorized under the laws of this State to perform a marriage ceremony,” we are compelled in the present case to conclude that Defendant met his high burden of demonstrating that *375Hawk Littlejohn was not authorized under the applicable version of N.C. Gen. Stat. § 51-1 to solemnize the 1989 ceremony.
We do not agree with the trial court’s conclusion that N.C. Gen. Stat. § 51-1.1 passed by our Legislature in 1981, the year after Lynch was decided, renders the 1989 ceremony valid. Specifically, the trial court correctly found that “the Legislature passed N.C. Gen. Stat. Sec. 51-1.1 in 1981, prior to the parties [sic] marriage, which expressly validated all marriages performed by ministers of the Universal Life Church prior to July 3, 1981[,]” but then erroneously concluded that “the effect of [N.C. Gen. Stat. § 51-1.1] is to give legislative approval to marriages performed by ministers of the Universal Life Church[.]”
In other words, we believe the trial court erred by concluding that our Legislature intended to give its approval to marriage ceremonies performed by ministers of the Universal Life Church, even if they were performed after 3 July 1981, because we believe the express terms of the statute validated only those otherwise voidable marriages solemnized by a minister of the Universal Life Church before 3 July 1981. See Meza v. Div. of Soc. Servs., 364 N.C. 61, 66, 692 S.E.2d 96, 100 (2010) (stating that “[w]hen the language of a statute is clear and without ambiguity, it is the duty of this Court to give effect to the plain meaning of the statute, and judicial construction of legislative intent is not required”).
Indeed, in Fulton v. Vickery, this Court described N.C. Gen. Stat. § 51-1.1 as a “curative statute.” 73 N.C. App. at 385, 326 S.E.2d at 357. In other words, by limiting the scope of the statute only to those marriages performed prior to 3 July 1981, the Legislature intended to provide relief to any “innocent” couple whose marital status was suddenly put in doubt by the Lynch decision. However, had the Legislature intended to validate otherwise voidable marriages solemnized by the Universal Life Church/or all time, it could have easily done so.5
In this case, since the trial court found that the parties were married by Hawk Littlejohn on a date after 3 July 1981, the curative effect of N.C. Gen. Stat. § 51-1.1 would not apply. Accordingly, the parties’ marriage — as based on the 1989 ceremony — was voidable, and subject to attack in a direct proceeding pursuant to N.C. Gen. Stat. § 50-4.
*3762. Judicial Estoppel
Defendant argues that the trial court erred by concluding that, even if the 1989 ceremony was voidable, Defendant was judicially estopped from contesting its validity. We agree.
Our Supreme Court has stated that three factors are to be considered in applying the doctrine of judicial estoppel: (1) whether a party’s position in a legal proceeding is clearly inconsistent with an earlier position taken in a legal proceeding; (2) whether the party succeeded in persuading a court to accept the party’s earlier position; and (3) whether the party seeking to assert the inconsistent position would derive some unfair advantage or impose an unfair detriment on the opposing party. Whitacre v. BioSignia, Inc., 358 N.C. 1, 29, 591 S.E.2d 870, 888-89 (2004).
In this case, the trial court’s order does not contain any finding that Defendant took the position in this or any other judicial proceeding that the 1989 ceremony was valid. Rather, the record reflects that Defendant denied in his initial pleading in this action Plaintiff’s allegation that they were married in 1989. Accordingly, we hold that the trial court erred by concluding that Defendant was judicially estopped from contesting the validity of the 1989 ceremony.
3. Equitable Estoppel
Defendant argues that the trial court erred by concluding that he is equitably estopped from challenging the validity of the 1989 ceremony. Specifically, he argues that Plaintiff is barred from asserting equitable estoppel because she has “unclean hands” by having participated in the 1989 ceremony. Plaintiff, on the other hand, argues that estoppel6 does apply in this case. In support of their respective positions, each party has cited opinions from this Court and our Supreme Court which address the propriety of estopping a party from challenging the validity of a void or voidable marriage. We have carefully reviewed these cases and believe that the trial court correctly concluded that Defendant was equitably estopped from challenging the validity of the 1989 ceremony.
*377Whether principles of estoppel apply “tum[s] on the particular facts of each case.” Mayer, 66 N.C. App. at 535, 311 S.E.2d at 668. The application of estoppel in divorce actions in North Carolina can be illustrated in three cases decided by this Court, Hurston v. Hurston, 179 N.C. App. 809, 635 S.E.2d 451 (2006); Redfern v. Redfern, 49 N.C. App. 94, 270 S.E.2d 606 (1980); and Mayer, supra, each of which involved (1) a wife seeking post-marriage support from her husband; (2) the husband seeking to avoid such obligation by asserting that the marriage was void based on the fact that either he or his putative wife had failed to obtain a valid divorce from a prior marriage; and (3) the wife contending that her putative husband was estopped from contesting the validity of their marriage. We compare each of these decisions below.
Hurston, a case relied upon by Defendant, involved facts at one extreme of the spectrum. There, it was the wife who had been previously married and who had obtained an invalid Dominican Republic divorce. Therefore, we held in Hurston that the wife could not assert estoppel because she had “unclean hands,” reasoning that though her putative husband “might have been negligent” by not ever questioning during the marriage the validity of the wife’s first divorce, “it was the [wife] who did not obtain the valid divorce decree before attempting to enter into another marriage],]” describing her as being “culpably negligent.” Hurston, 179 N.C. App. at 815, 635 S.E.2d at 454. Accordingly, we held that the husband was not equitably estopped from contesting the validity of the marriage.
Redfem involved facts on the other extreme of the spectrum. Specifically, in Redfem, it was the husband — and not the wife — who had been previously married and had entered the second marriage before, unbeknownst to his putative wife, the divorce decree from his first marriage had been signed. This Court determined that the husband was culpably negligent in failing to obtain a signed divorce decree; and, therefore, he was estopped from contesting the validity of the second marriage as his defense to avoid paying support to his putative wife. Redfern, 49 N.C. App. at 97, 270 S.E.2d 608-09.
The facts in Mayer fall between the extremes of Hurston and Redfem. Like the wife in Hurston, the wife in Mayer had obtained an invalid Dominican Republic divorce in an attempt to end her first marriage. However, unlike the putative second husband in Hurston, the putative second husband in Mayer was involved in helping his wife obtain the invalid Dominican divorce from her first husband. Specifically, the putative second husband had insisted that his wife obtain the Dominican divorce and had accompanied her there to help her obtain the divorce. *378The putative second husband, nonetheless, argued that his wife should not be able to assert estoppel since “the equities in this case weigh no more heavily for [the wife] than for him since [inter alia] she and he are in pari delicto [in that she participated equally with him to obtain the Dominican divorce].” Mayer, 66 N.C. App. at 531, 311 S.E.2d at 666. This Court concluded that even though no children had been bom to the marriage and though the parties had not been married for that long, the scales of equity still tipped towards allowing the wife to assert estop-pel to bar her putative second husband’s defense to her claim for spousal support. Id. at 66 N.C. App. at 535, 311 S.E.2d at 668. Specifically, this Court stated that to allow a party to a marriage to challenge the validity of that marriage where he was actively involved in obtaining an invalid divorce for his putative spouse and which was relied upon by his putative spouse would cause “matrimonial uncertainty.” Id. We note that in Taylor v. Taylor, our Supreme Court cited our analysis in Mayer with approval, quoting our reasoning that “ ‘in spite of the criticism that the application of a quasi-estoppel doctrine circumvents a state’s divorce law, it would be even more mimical to our law and to our public policy to permit [the husband] to avoid his marital obligations by acting inconsistently with his prior conduct.” 321 N.C. 244, 250-51, 362 S.E.2d 542, 546-47 (1987) (citation omitted) (alteration in original).
We believe that the facts in the present case —. as found by the trial court in the 2007 order — are most similar to the facts in Mayer. Specifically, the findings suggest that both Plaintiff and Defendant were equally negligent in relying on Hawk Littlejohn’s credentials. Accordingly, we believe that the trial court correctly applied the law in concluding that Defendant was equitably estopped from challenging the validity of the 1989 ceremony.
The scales of equity might have tipped towards Defendant had the evidence shown that Plaintiff had actually known at the time of the 1989 ceremony that Hawk Littlejohn was not authorized to solemnize a North Carolina marriage or that she had misrepresented to Defendant prior to the 1989 ceremony that she had engaged in some due diligence to determine the validity of Hawk Littlejohn’s credentials where she, in fact, had not done so. Further, had Plaintiff not agreed to participate in the 2001 ceremony, the scales of equity would have swayed against her, at least with respect to any benefit she seeks in this action that relates to the period of the marriage occurring after she had learned in 2001 that her marriage was voidable. However, there is no evidence in the record indicating that Plaintiff was any more culpable than the wife in Mayer. We note that Defendant has pled allegations that might enhance Plaintiff’s *379culpability, including allegations about her expertise in Native American culture and her desire and insistence that she and Defendant participate in the traditional Cherokee ceremony officiated by Hawk Littlejohn. However, there is nothing in the Rule 9(c) statement indicating that any testimony or other evidence was presented to the trial court regarding these allegations. Rather, the Rule 9(c) statement simply recites that the parties both testified and that the testimonial evidence supported many of the trial court’s findings in the 2007 order.
Accordingly, we affirm the trial court’s determination that the date of marriage for purposes of this action is 15 October 1989. Further, because we hold that the trial court did not err in concluding that 15 October 1989 was the date of marriage for all matters related to this action, we necessarily hold that the trial court did not err in basing all subsequent orders on that date of marriage.
III. Dependent Spouse Determination
In his final argument, Defendant contends that, in its 31 March 2008 order, the trial court erred in making its conclusion of law 2, which states as follows:
Taking into account the income and expenses of the parties living as [a] family unit for the several months prior [to] the separation of the parties, . . . Plaintiff is without sufficient means to maintain her accustomed standard of living and . . . Plaintiff is, therefore, a dependent spouse in that she is actually substantially dependent on . . . Defendant for her support as of the date of separation. Further, given that... Plaintiff’s income is not sufficient to meet her monthly expenses,... Plaintiff is substantially in need of maintenance and support.
Defendant, however, makes no argument in his brief that any specific findings in the order are not supported by competent evidence. Defendant only nonspecifically argues that “the trial court erred in its legal conclusion #2 that. . . [P]laintiff is ‘actually substantially dependent on... Defendant for her support as of the date of separation,’... as that conclusion was based on a finding that is not supported by the evidence.” “Findings of fact to which no error is assigned ‘are presumed to be supported by competent evidence and are binding on appeal.’ ” Pascoe v. Pascoe, 183 N.C. App. 648, 650, 645 S.E.2d 156, 157 (2007) (citation omitted). This Court has held that when an appellant, as here, fails to argue specifically in his brief that contested findings of fact were unsupported by the evidence, any such argument is abandoned. Peters *380v. Pennington, 210 N.C. App. 1, 16, 707 S.E.2d 724, 735 (2011) (citation omitted). Since Defendant made no argument as to which, if any, of the findings of fact in the trial court’s 31 March 2008 order were unsupported, “this Court is therefore bound to accept as true the information therein.” Pascoe, 183 N.C. App. at 651, 645 S.E.2d at 158 (citation omitted). We have nevertheless reviewed the relevant findings of fact and conclude that they are supported by competent record evidence and are binding on appeal. Therefore, we hold that the trial court did not err in finding Plaintiff to be actually substantially dependent on Defendant, and Defendant’s argument to the contrary is without merit.
AFFIRMED.
Judge DAVIS concurs.. In Defendant’s verified complaint, he alleged that Hawk Littlejohn was not, in fact, a Native American but had changed his name from his given name, Larry Snyder.
. In late 2007, Defendant appealed from the 2007 order. However, this Court dismissed the interlocutory appeal for lack of jurisdiction. Duncan v. Duncan, 193 N.C. App. 752, 761 S.E.2d 71, 2008 WL 4911807 (2008) (unpublished).
. N.C. Gen. Stat. § 51-1 was amended in 2001 to add a provision winch authorizes a ceremony to be valid as long as it is held “[i]n accordance with any mode of solemnization recognized by any religious denomination, or federally or State recognized Indian Nation or Tribe.” N.C. Gen. Stat. § 51-1(2) (2013).
. The record states that the audio recording of the hearing has been lost.
. There is no evidence in the record regarding the current criteria for ordination in the Universal Life Church; and, accordingly, we express no opinion about marriages that might have been solemnized by other Universal Life Church ministers since Lynch. Further, we express no opinion regarding the voidability of marriages solemnized by a Universal Life Church minister under the current version of N.C. Gen. Stat. § 51-1.
. The trial court concluded that Defendant was “equitably estopped” from challenging the validity of the 1989 ceremony. In the cases cited by the parties, the reviewing courts employ both the doctrines of “equitable estoppel” and “quasi-estoppel.” Our Supreme Court has described “quasi-estoppel” as a “branch of equitable estoppel” with the key distinction being that the former “may operate without detrimental reliance on the part of the party invoicing the estoppel.” Whitacre, 358 N.C. at 18, 591 S.E.2d at 882. We believe that the distinction is insignificant in the present case and believe that the cases considering either doctrine are helpful in our resolution of this issue. See Mayer v. Mayer, 66 N.C. App. 522, 532-36, 311 S.E.2d 659, 666-69 (1984) (relying on analyses in cases applying “equitable estoppel” though applying “quasi-estoppel” principles).
