We granted Regina Scott’s application for discretionary appeal to address whether a self-executing change of custody provision in the Scotts’ divorce decree was permissible under Weaver v. Jones, 260 Ga. 493 (396 SE2d 890) (1990) and Pearce v. Pearce, 244 Ga. 69 (257 SE2d 904) (1979). For the reasons that follow, we find that the automatic custody change provision was not a permissible extension of Weaver and Pearce and should be stricken from the parties’ divorce decree.
Regina and Charles Scott were divorced in 2001. Custody of their two-year-old daughter was placed jointly in the parties with Ms. Scott given primary physical custody. The divorce decree further provided in Paragraph 3 that
in the event that [Ms. Scott] moves to a residence outside of Cobb County, Georgia, it is hereby ordered and the court specifically finds, that this event constitutes a material *373change in circumstances detrimentally affecting the welfare of the minor child and that pursuant to Carr v. Carr, 207 Ga. App. 611 [(429 SE2d 95)] (1993), primary physical custody of the minor child shall automatically revert to [Mr. Scott]. This provision is a self-effectuating change of custody provision and no action of the Court shall be necessary to accomplish this change of custody.
The best interests of the child are controlling as to custody changes. OCGA § 19-9-3 (a) (2); Parr v. Parr, 196 Ga. 805 (27 SE2d 687) (1943). Whether particular circumstances warrant a change in custody is a fact question determined under the unique situation in each individual case. Wilson v. Wilson, 241 Ga. 305 (245 SE2d 279) (1978). In contemplating a custodial change, the trial court must exercise its discretion to determine whether a change is in the best interests of the child. OCGA § 19-9-3. The circumstances warranting a change in custody are not confined to those of the custodial parent: any new and material change in circumstances that affects the child must also be considered. Handley v. Handley, 204 Ga. 57, 59 (48 SE2d 827) (1948). The law thus recognizes that because children are not immutable objects but living beings who mature and develop in unforeseeable directions, the initial award of custody may not always remain the selection that promotes the best interests of the child.
Self-executing change of custody provisions allow for an “automatic” change in custody based on a future event without any additional judicial scrutiny. Our appellate courts have upheld several such automatic custody change provisions. In Weaver, supra, the parties contemplated that an older child, upon reaching the age of 14, might utilize the statutory procedures allowing a child of that age to choose the parent with whom the child wishes to reside. See OCGA §§ 19-9-1 (a) (3) (A), 19-9-3 (a) (4). Accord Pearce, supra (under terms of agreement, “each of the children shall be given the opportunity to decide” the parent with whom the child preferred to reside1). The self-executing change of custody provisions in those two cases thus provided that upon the child deciding to reside with the noncustodial parent, the obligations of the parents would switch automatically without further court intervention. The self-executing change of custody provisions in Weaver and Pearce were thus consonant with statutory and case law, which recognizes that “[a] child’s selection of the parent with whom he desires to live, where the child *374has reached 14 years of age, is controlling absent a finding that such parent is unfit. Without a finding of unfitness the child’s selection must be recognized and the court has no discretion to act otherwise. [Cits.]” Harbin v. Harbin, 238 Ga. 109-110 (230 SE2d 889) (1976).
The self-executing custody change provisions in Weaver and Pearce pose no conflict with our law’s emphasis on the best interests of the child. The same, however, cannot be said of other automatic change of custody provisions the appellate courts have earlier approved. It is well established that “Georgia law does not permit a modification of custody based solely on a custodial parent’s relocation” to another home, city or state, Ofchus v. Isom, 239 Ga. App. 738, 739 (1) (521 SE2d 871) (1999), or merely upon the custodial parent’s remarriage. See Mercer v. Foster, 210 Ga. 546 (3) (81 SE2d 458) (1954). Nevertheless, the appellate courts have ignored this case law to approve self-executing change in custody provisions triggered by remarriage or relocation that mandate, without regard to the child’s best interests, the removal of the child from the custodial parent. In Holder v. Holder, 226 Ga. 254 (174 SE2d 408) (1970), this Court approved a provision that automatically stripped the mother of custody of her children upon her remarriage. Looking only to whether the provision operated as a restraint upon marriage, this Court concluded that the mother “had the election whether to remarry or to retain custody of the children. She elected to remarry, and thereupon her right to custody under the agreement and decree ceased. [Cits.]” Id. at 256 (1). As to the trial court’s ruling that there had been no showing of a material change of circumstances substantially affecting the welfare and best interests of the children, we concluded in abbreviated fashion that change of circumstances was “not involved here.” Id. at 256 (3). See also Hunnicutt v. Sandison, 223 Ga. 301, 303-304 (1) (154 SE2d 587) (1967) (approving provision in divorce decree granting custody of children to appellant “so long as he did not remarry, and that in the event he remarried, the appellee would have custody of the children”).
Likewise, in Carr, supra, expressly relied upon by the trial court here, the divorce decree mandated a change in custody from the primary to the secondary custodial parent “in the event that either parent moves to another city (outside the metropolitan Atlanta area) or another state.” Id., 207 Ga. App. at 611. The Court of Appeals upheld the provision looking solely to the fact that it “did not prohibit [Ms.] Carr from moving, it simply set forth self-executing consequences if she decided to do so,” id. at 612, and finding the provision “more akin” to the provisions approved by this Court in Weaver and Pearce, *375supra. Id. at 613.2
We find no kinship between the flexible self-executing change of custody provision in Weaver that is designed to accommodate a 14-year-old child’s exercise of his or her statutory right to select the parent with whom the child desires to live, see also Pearce, and the draconian custody change provisions in Carr and Holder that altogether ignore the best interests of the child at the time of the triggering event.3 Once the triggering event occurs — such as remarriage or relocation — the child is automatically uprooted without any regard to the circumstances existing at that time. See Holder, supra at 256 (3). These provisions are utterly devoid of the flexibility necessary to adapt to the unique variables that arise in every case, variables that must be assessed in order to determine what serves the best interests and welfare of a child. Unlike the Weaver/Pearce provisions, the purpose of the automatic custody change provisions in Carr/Holder is not to accommodate a child’s rights and needs. Rather, the purpose is to provide a speedy and convenient short-cut for the non-custodial parent to obtain custody of a child by bypassing the objective judicial scrutiny into the child’s best interests that a modification action pursuant to OCGA § 19-9-3 requires. This “short-cut” operates at the expense of the child, even though
[a] change of custody is just as important to the child and to others as an original award of custody, and the parties should be afforded the same type of hearing on the subsequent application as they are entitled to on an original award. [Cit.], quoting 24 Am. Jur. 2d Divorce and Separation § 1008 (1983).
(Punctuation omitted.) Clapper v. Harvey, 716 A2d 1271, 1275 (Pa. Super. 1998).
While self-executing change of custody provisions are not expressly prohibited by statutory law, we hold that any such provision that fails to give paramount import to the child’s best interests in a change of custody as between parents violates this State’s public policy as expressed in OCGA § 19-9-3.
*376The trial court here found that relocating the Scotts’ child outside of Cobb County “constitutes a material change in circumstances detrimentally affecting the welfare of the minor child.” However, self-executing change of custody provisions are not rendered valid merely because the initial award of custody may have been based upon the child’s best interests. It is not the factual situation at the time of the divorce decree that determines whether a change of custody is warranted but rather the factual situation at the time the custody modification is sought.4 See Mallette v. Mallette, 220 Ga. 401, 403 (1) (139 SE2d 322) (1964); Danziger v. Shoob, 203 Ga. 623, 625 (48 SE2d 92) (1948).
Remarriage and relocation directly affect a child but they do not automatically warrant a change in custody. Mercer, supra, 210 Ga. at 548 (3); Ormandy v. Odom, 217 Ga. App. 780, 781 (459 SE2d 439) (1995). There are situations, such as the remarriage of a custodial parent to a loving stepparent or the relocation of residence to a superior school district or a safer neighborhood, where the change in circumstances clearly would promote the child’s best interests and welfare. See Wallerstein and Tanke, To Move or Not to Move: Psychological and Legal Considerations in the Relocation of Children Following Divorce, 30 Fam. L. Q. 305 (1996). The variables are too unfixed to determine at the time of the divorce decree what effect a future remarriage or relocation may have on a child. While many children experience a degree of trauma or difficulty as the result of a custodial parent’s remarriage or the relocation of the family unit, that emotional upset constitutes only a factor that can be “considered in the totality of the circumstances [cit.] and balanced in determining whether a change of condition occurred.” In the Interest of R.R., 222 Ga. App. 301, 305 (2) (474 SE2d 12) (1996).
The dissent posits that without a self-executing custody change provision, a child’s best interests may be damaged as the result of the custodial parent’s relocation before a modification action can be successfully concluded. However, custodial parents cannot simply pick up and move on a moment’s notice without notifying the noncustodial parent. See OCGA § 19-9-1 (c) (3), providing that notification “shall be given” by a custodial parent to the non-custodial parent and any other person granted visitation rights “at least 30 days prior to the anticipated change of residence”; id. at (c) (1), providing that *377the court awarding custody of a minor “shall retain jurisdiction of the case for the purpose of ordering the custodial parent to notify the court of any changes in the residence of the child.” This argument also fails to recognize that an automatic custody change provision forces the custodial parent to initiate judicial proceedings to maintain custody of a child even when there is no evidence other than the remarriage or the move itself to indicate a change in the child’s circumstances.5
Neither the convenience of the parents nor the clogged calendars of the courts can justify automatically uprooting a child from his or her home absent evidence that the change is in the child’s best interests. The paramount concern in any change of custody must be the best interests and welfare of the minor child. Jordan v. Jordan, 195 Ga. 771 (25 SE2d 500) (1943). Therefore, we repudiate our holding in Holder and disapprove the opinion in Carr, supra, 207 Ga. App. at 611, relied upon by the trial court to impose the self-executing change of custody provision upon Ms. Scott in the instant appeal. Because the provision in Paragraph 3 of the parties’ divorce decree fails to provide for a determination whether the custody change is in the best interest of the parties’ daughter at the time the change would automatically occur, it violates the public policy as expressed in OCGA § 19-9-3. It follows that the trial court’s denial of Ms. Scott’s motion is reversed and the divorce decree is vacated with direction that the trial court set aside Paragraph 3 of the decree.
Judgment reversed with direction.
All the Justices concur, except Sears, P. J., and Carley, J., who dissent.The age of the children in Pearce was not pertinent to our holding therein and the opinion contains no discussion regarding the applicability of OCGA §§ 19-9-1 (a) (3) (A), 19-9-3 (a) (4) to the parties’ decision to allow their children to choose the parent with whom they wanted to reside.
This Court denied certiorari in Carr, after initially granting then vacating the writ, on the basis that it failed to satisfy the relevant criteria. Carr v. Carr, 263 Ga. 451 (435 SE2d 44) (1993). “The denial of a writ of certiorari by the Supreme Court is not binding as a precedent in another case, and does not come within the doctrine of stare decisis.” Seaboard A.L. Ry. v. Brooks, 151 Ga. 625, 631 (107 SE 878) (1921).
No relevant distinction may be drawn between self-executing change of custody provisions based upon their source. Whether originating with the parties, a guardian ad litem or the trial judge, once the provision is incorporated into the divorce decree it stands on equal footing with all the provisions in the decree passed upon and ordered by the trial court.
Our sister states have recognized that these types of automatic custody change provisions should not be given effect because they are premised on a “mere speculation” of what the best interests of the children may be at a future date. See, e.g., Zeller v. Zeller, 640 NW2d 53 (N.D. 2002); deBeaumont v. Goodrich, 644 A2d 843 (Vt. 1994); Hovater v. Hovater, 577 So2d 461 (Al. Civ. App. 1990). It has been recognized that “a majority of jurisdictions treat stipulations regarding the automatic change of custody as void.” Zeller, supra at 59 (Sandstrom, J., dissenting).
Regarding the speedy resolution of custody disputes in the court, we agree with Judge Beasley’s exhortation that
[t]he judicial process for resolving custody disputes should be expedited all along the way so that the dynamic character of the children’s growth and development is not prejudiced or harmed by delayed change of custody when that is needed or by the insecurity of inconclusiveness if custody is to remain the same.
