Custody Modification Based on Parent–Child Relationship Breakdown; Parental Alienation Requires Proof, and Therapeutic Parenting Time May Bridge Reunification

Introduction

In Matter of David JJ. v Tara KK., 2025 NY Slip Op 04063 (App Div 3d Dept July 3, 2025), the Third Department affirmed a Family Court order modifying a prior consent custody order under Family Ct Act article 6. The parties are the divorced parents of a son (born 2011). Under a July 2018 consent order, the mother had sole legal custody and primary physical custody, with parenting time to the father as agreed.

The modification litigation was triggered in April 2023 after the child reported a physical altercation with the mother. The father petitioned for sole legal custody and primary physical custody; Family Court issued temporary orders granting him that relief and restricting the mother to supervised visitation. After a fact-finding hearing and a Lincoln hearing, Family Court modified the 2018 order to award joint legal custody, primary physical custody to the father, and therapeutic parenting time for the mother. On appeal, the mother challenged evidentiary rulings, the change-in-circumstances finding, best-interests determinations, and argued that the father had engaged in parental alienation.

Summary of the Opinion

  • Evidentiary error identified but deemed harmless: Family Court improperly allowed testimony describing video recordings that were not admitted, violating the best evidence rule, but the error was harmless given corroboration and other sufficient proof.
  • Change in circumstances established: A breakdown/deterioration of the mother–child relationship—confirmed by the mother and reflected in the child’s refusal to return or communicate—constituted a change in circumstances warranting a best-interests inquiry.
  • Best interests supported modification: The record provided a sound and substantial basis for joint legal custody and primary physical custody to the father, including concerns arising from the mother’s admissions about statements made to the child.
  • Parental alienation claim rejected: The mother’s allegation was unsupported; speculation and a single uncorroborated claim were insufficient.
  • Therapeutic parenting time affirmed: Given the child’s distress and the goal of repairing the relationship safely, therapeutic parenting time was appropriate.

Analysis

Precedents Cited

1) Best evidence rule and harmless error

The court held it was error to permit a caseworker to testify about the contents of videos not admitted into evidence, where the contents were disputed and the unavailability was unexplained, relying on Schozer v William Penn Life Ins. Co. of N.Y., 84 NY2d 639 (1994). Schozer supplies the controlling framework for when secondary evidence of a recording’s contents may be used; absent an adequate foundation regarding unavailability and authenticity, such testimony is improper.

Nonetheless, the Third Department applied a practical harmless-error analysis—because Family Court “placed little reliance” on the improper testimony, key allegations were corroborated by admissible evidence, and the record otherwise supported the outcome—citing Matter of Traci A. v Maxmillion B., 232 AD3d 1070 (3d Dept 2024) and Matter of Brandon HH. v Megan GG., 214 AD3d 1036 (3d Dept 2023). The decision thus reinforces that, in custody litigation, evidentiary missteps will not compel reversal absent demonstrated prejudice, especially where independent, admissible proof supports the best-interests findings.

The court similarly disposed of hearsay objections by pointing to corroboration or otherwise sufficient evidence, invoking Matter of Cassidy S. v Bryan T., 180 AD3d 1171 (3d Dept 2020) and Matter of Cory O. v Katie P., 162 AD3d 1136 (3d Dept 2018). These cases reflect the Third Department’s recurring emphasis that, even where hearsay appears, custody determinations stand if supported by a sound evidentiary basis overall.

2) Modification standard: change in circumstances

The court restated the settled two-step modification inquiry: first, the movant must show a post-order change in circumstances warranting reconsideration; second, the court evaluates the best interests. For this principle the court cited Matter of Tara DD. v Seth CC., 214 AD3d 1031 (3d Dept 2023).

The court then explained that “new developments or changes” suffice, citing Matter of John EE. v Jalyssa GG., 222 AD3d 1219 (3d Dept 2023), and specifically recognized that deterioration of the child’s relationship with a parent can constitute the requisite change. For that proposition it relied on Matter of C.M. v Z.N., 230 AD3d 1409 (3d Dept 2024), Theodore P. v Debra P., 209 AD3d 1146 (3d Dept 2022), and Matter of John V. v Sarah W., 143 AD3d 1069 (3d Dept 2016).

Applying those precedents, the court treated the post-2018 collapse of the mother–child relationship—accelerating after the April 2023 altercation and followed by the child’s refusal to return or communicate—as a legally sufficient change in circumstances. The court also aligned its conclusion with Matter of Lora PP. v Alphonso PP., 221 AD3d 1321 (3d Dept 2023) and Matter of Sarah I. v Ian J., 233 AD3d 1334 (3d Dept 2024), lv denied 43 NY3d 904 (2025), reflecting continued acceptance that relational breakdown can justify reopening custody.

3) Best interests factors and appellate deference

The court summarized the best-interests matrix—fitness, past parenting performance, home environments, domestic violence, the child’s wishes, and each parent’s willingness to foster the other relationship—citing Matter of Matthew DD. v Amanda EE., 187 AD3d 1382 (3d Dept 2020). On children’s expressed preferences (considering age, maturity, and susceptibility to influence), it relied on Matter of Chad KK. v Jennifer LL., 219 AD3d 1581 (3d Dept 2023).

The opinion underscores that parenting time is generally presumed beneficial, but a rigid schedule is not required where detrimental, citing Matter of Lora PP. v Alphonso PP., 221 AD3d 1321 (3d Dept 2023). It further emphasized strong appellate deference to Family Court’s credibility assessments, citing Matter of Michelle L. v Steven M., 227 AD3d 1159 (3d Dept 2024).

In affirming joint legal custody, the court invoked Matter of Christina E. v Clifford F., 200 AD3d 1111 (3d Dept 2021) for the proposition that joint legal custody is an “aspirational goal” when parties demonstrate they can communicate sufficiently, even amid hostility. In affirming primary physical custody to the father, it cited Matter of James EE. v Vanessa EE., 228 AD3d 1025 (3d Dept 2024) and again Matter of Michelle L. v Steven M., 227 AD3d 1159 (3d Dept 2024), anchoring the holding in the “sound and substantial basis” standard.

4) Parental alienation: definition and evidentiary burden

The Third Department applied its established definition of alienation as willful interference with the other parent’s access rights, so inconsistent with best interests that it “per se” signals probable unfitness, citing Matter of Jahari BB. v Zada CC., 232 AD3d 1142 (3d Dept 2024). It also cited Matter of Luke v Erskine, 222 AD3d 868 (2d Dept 2023), demonstrating doctrinal consistency across departments.

Critically, the court required evidentiary support, not inference: the mother offered only a single unsupported allegation and speculation, no documentary proof, and no expert/medical testimony. The court contrasted that absence with the mother’s own admissions of conduct potentially impeding the father–child relationship. In rejecting the alienation claim, the court relied on Matter of Kaczynski v Van Amerongen, 284 AD2d 600 (3d Dept 2001), and distinguished cases where the record can support alienation findings by citing Matter of Dobies v Brefka, 83 AD3d 1148 (3d Dept 2011) as a “compare” authority.

5) Therapeutic parenting time

The court upheld therapeutic parenting time given the child’s distress at the prospect of contact, the father’s support for counseling, and the goal of rebuilding safely, citing Lora PP. v Alphonso PP., 221 AD3d 1321 (3d Dept 2023) and Matter of Sarah I. v Ian J., 233 AD3d 1334 (3d Dept 2024). The decision confirms that therapeutic parenting time is an appropriate tool where immediate, conventional visitation may be harmful but continued relationship repair is in the child’s interests.

Legal Reasoning

  1. Procedural/evidentiary gatekeeping, then prejudice: The panel first addressed claimed trial errors. It agreed one ruling violated the best evidence rule but treated it as harmless due to limited reliance and corroboration. This sequencing preserves doctrinal rigor while preventing reversal where the final custody result rests on a broader, admissible record.
  2. Threshold change in circumstances satisfied by relational breakdown: The court treated the post-order collapse of the mother–child relationship—accelerating after a physical incident and followed by sustained refusal to return/communicate— as a substantial enough development to reopen custody.
  3. Best interests anchored in child welfare and parental conduct: The court affirmed joint legal custody because the parties could still coordinate exchanges and parenting time despite hostility, and because joint decision-making remained viable. It affirmed primary physical custody to the father because the child would not return to the mother, and because the mother’s admissions (including highly inappropriate statements about the father and statements designed to burden the child emotionally) reflected serious parental fitness concerns.
  4. Alienation requires proof, not narrative: The court did not treat “parental alienation” as a label that shifts custody by allegation alone. It required concrete evidence of willful interference and found none on this record.
  5. Repair, not rupture, where possible: The therapeutic parenting time component reflects a reunification-oriented approach: even while changing primary residence, the court preserved a structured path for restoring a healthier mother–child relationship, conditioned on therapeutic support.

Impact

  • Relationship breakdown as a recurring “change in circumstances” trigger: The decision strengthens the Third Department’s line of cases treating deterioration—especially after an incident involving physical conflict and subsequent refusal of contact—as sufficient to revisit custody. Practitioners should expect courts to treat sustained parent–child estrangement as more than a transient disagreement, particularly when corroborated by testimony and the child’s behavior.
  • Alienation claims face an evidentiary gate: The opinion signals that alienation arguments require more than conjecture; absent corroboration, records, communications, or expert testimony, courts may view alienation allegations skeptically—especially where the accusing parent’s own conduct appears relationship-damaging.
  • Therapeutic parenting time endorsed as a best-interests tool: Where a child experiences distress around contact, this case supports therapeutic parenting time as a tailored alternative to rigid visitation schedules, balancing emotional safety with the long-term goal of restoring parental bonds.
  • Harmless error doctrine in custody trials: Even when best evidence principles are breached, appellate courts may affirm if the ultimate custody findings rest on a sound, independent evidentiary foundation. Trial counsel should still preserve objections, but appellate strategy must identify prejudice—i.e., how the error materially drove the outcome.

Complex Concepts Simplified

Best evidence rule
A rule that generally requires the original recording/document (or a properly admitted duplicate) when a party seeks to prove its contents. If the video itself is not admitted, a witness usually cannot substitute by testifying “what the video showed” unless strict conditions are met (such as explaining unavailability).
Lincoln hearing
A private, in-camera interview of the child by the judge in a custody case (typically outside the parents’ presence) to hear the child’s views and experiences while reducing pressure on the child.
Change in circumstances
The required threshold showing to reopen an existing custody order. Courts will not relitigate custody without proof that something meaningful has changed since the last order—such as a significant deterioration in the child’s relationship with a parent.
Best interests of the child
The controlling standard for custody/parenting time decisions, assessed by multiple factors (stability, parental fitness, ability to co-parent, home environment, and the child’s needs and wishes, among others).
Joint legal custody vs. primary physical custody
Joint legal custody means both parents share decision-making authority on major issues (education, medical care, etc.). Primary physical custody concerns where the child mainly lives day-to-day.
Parental alienation
Willful behavior by one parent that undermines the child’s relationship with the other parent (for example, systematically blocking access or poisoning the child’s view). Courts generally require concrete evidence of such interference; it is not established by allegation alone.
Therapeutic parenting time
Visitation that occurs with therapeutic support—often involving a counselor or structured therapeutic plan—to help repair or build a healthy parent–child relationship when ordinary visitation may be emotionally harmful or conflict-laden.
504 plan
A school-based accommodation plan under Section 504 of the Rehabilitation Act to support a student with a disability so the student can access education comparably to peers.

Conclusion

Matter of David JJ. v Tara KK. reaffirms several practical custody doctrines in the Third Department: (1) custody modification requires a threshold change in circumstances, and a sustained parent–child relationship breakdown can satisfy that requirement; (2) best-interests determinations—especially credibility-driven ones—receive substantial appellate deference when supported by a sound and substantial basis; (3) parental alienation is a serious charge that demands evidentiary support, not speculation; and (4) therapeutic parenting time is an endorsed mechanism to protect a distressed child while preserving the possibility of reunification and healthier future contact.
