A New York appellate court has upheld a Family Court ruling that denied a mother's request to change custody and visitation arrangements for her child. The decision, made by the Appellate Division of the Supreme Court on October 9, 2026, affects Kristin S. Buchholz and Robert Trombley, Jr., who have been in a legal dispute over custody. The ruling emphasizes the importance of a child's best interests in custody decisions.

The case, known as Matter of Buchholz v. Trombley, was filed under docket number 618 CAF 25-00372. The court's decision comes after a previous order from Family Court in Genesee County dismissed Buchholz's petition for modification of custody and visitation. This ruling is significant as it reinforces the standards courts use when determining custody issues, particularly the best interests of the child.

Kristin S. Buchholz is the petitioner in this case, seeking to modify an existing custody arrangement with her former partner, Robert Trombley, Jr. The dispute arose after Buchholz withdrew her request concerning their oldest child during the hearing. This left the court to focus on the custody arrangement for their younger child. The Family Court had to evaluate various factors to determine what would be in the best interests of the child, including the current home environment and the emotional and intellectual development of the child.

The case reached the appellate court after Buchholz appealed the Family Court's decision from February 20, 2025. The appeal was heard by a panel of judges, including Curran, Montour, Ogden, Delconte, and Skinner. The court's ruling emphasized that the Family Court's determination regarding custody is entitled to great weight, especially when based on firsthand assessments of witness credibility.

The court ruled that Buchholz did not provide sufficient evidence to support her claim that modifying the custody arrangement would be in the best interests of the child. The judges stated, "a sound and substantial basis in the record supports the court's determination that the mother failed to establish that the requested modification would be in the best interests of the child." This statement highlights the court's reliance on existing evidence and assessments made during the Family Court proceedings.

Additionally, the court noted that Buchholz's claim of bias against the Family Court was not preserved for review, as she did not request the court's recusal during the initial proceedings. This aspect of the ruling underscores the importance of following proper legal procedures when raising concerns about a judge's impartiality.

The impact of this ruling is significant for families navigating custody disputes in New York. It reinforces the principle that courts will prioritize the best interests of the child above all else when making custody decisions. This case serves as a reminder that parents seeking to modify custody arrangements must present compelling evidence to support their claims.

Moving forward, this ruling may influence similar cases in New York, as it sets a clear standard for how courts evaluate custody modifications. Parents involved in custody disputes may need to be more prepared to demonstrate how changes in custody would benefit their children, as the court's focus remains on the child's welfare.

As for what comes next, it is unclear whether Buchholz will seek further appeal options. The court's ruling appears to be final unless new evidence emerges or procedural errors are identified. There are no related cases mentioned in the court filing, but the decision may have implications for future custody cases in the state.
