Background
Brandi Hunter (Mother) and Frank Bernhard (Father) share one child, born in 2017. A California court in Yolo County issued a custody and child support judgment in December 2021, awarding Mother sole physical custody and joint legal custody. The judgment required Mother to pay Father child support because he was unemployed at the time, but reserved jurisdiction to modify support retroactive to the date Father became employed. With the California court’s permission, Mother and Child relocated to St. Louis County, Missouri. Father subsequently purchased a home in Wildwood, Missouri in October 2022 to be closer to the child.
In December 2023, Father filed a motion in St. Louis County circuit court to modify the California custody judgment, seeking sole legal custody and designation as residential parent, citing concerns about the child’s education at City Garden Montessori charter school in St. Louis. He alleged the child was falling behind academically, displayed behavioral issues, and was confused by a gender-fluid teacher. Mother moved to dismiss three times, arguing Missouri lacked jurisdiction. The trial court rejected those challenges and, after trial, modified the judgment to award joint physical custody with equal parenting time, designated Father as residential parent for education and mailing purposes, and ordered Father to pay Mother $561 per month in child support. Mother also filed a cross-motion seeking retroactive child support back to Father’s first date of employment in June 2022.
Mother appealed on four grounds: (1) the court improperly refused to compel testimony from a Children’s Division investigator; (2) no change of circumstances existed to justify custody modification; (3) the child support calculation improperly credited Father’s claimed disability income; and (4) the court failed to give full faith and credit to the California judgment’s reservation of jurisdiction to make child support retroactive.
The Court’s Holding
The Court of Appeals affirmed on all four points. On Point One, the court found no abuse of discretion or prejudice in the refusal to compel the Children’s Division employee’s testimony, because other witnesses — including Father, the kindergarten principal, and the guardian ad litem — had already established that the allegation against the child’s teacher was unsubstantiated. The excluded testimony would have been cumulative, and the court’s residential designation rested on other grounds entirely, namely the child’s academic performance and the quality of available schooling in Father’s district.
On Point Two, the court held that Father’s relocation from California to Missouri constituted a substantial change of circumstances under section 452.411, satisfying the statutory threshold for modification under section 452.410. The court further found the modification was in the child’s best interests under the eight factors of section 452.375.2, crediting Father’s testimony and the guardian ad litem’s recommendation that the Rockwood school district would better serve the child academically. The court also noted Mother had been reluctant to allow Father meaningful parenting time after he moved to Missouri, a proper factor in the best-interests analysis. On Point Three, the court found no abuse of discretion in setting child support based on Father’s disability income of $3,000 per month, because there was no evidence Father was voluntarily limiting his income to evade support obligations — he had scheduled surgery and planned to return to his airline career within two years.
On Point Four, the court held that Missouri properly exercised jurisdiction to modify the California child support order because both parents and the child had relocated to Missouri, causing California to lose continuing exclusive jurisdiction under the Uniform Interstate Family Support Act (UIFSA). The three judges who had presided over this matter in Missouri, Yolo County, and Nevada County had reached a consensus that Missouri held jurisdiction over all financial matters. The court further found that the California judgment’s reservation of retroactive modification authority conferred no enforceable right on Mother — it merely left open a discretionary possibility that Missouri’s court was equally free to decline.
Key Takeaways
- Under Missouri section 452.411 and controlling precedent, a parent’s interstate relocation is itself a substantial change of circumstances sufficient to trigger the modification analysis under section 452.410 — no additional showing of changed circumstances is required.
- Exclusion of evidence is not reversible error where the same facts were established through other testimony, and an appellant must also demonstrate actual prejudice to the merits of the case.
- UIFSA’s continuing exclusive jurisdiction framework means that when all parties and the child have relocated to a new state, the issuing state loses jurisdiction and the new state may modify both custody and child support orders without being bound by jurisdictional reservations in the original order.
- Courts will not impute higher income to a non-custodial parent based on earning capacity unless the evidence establishes the parent is voluntarily reducing income to evade support obligations; disability payments tied to a temporary medical condition and a clear plan to return to work do not meet that threshold.
Why It Matters
This decision offers a useful illustration of how UIFSA operates in practice when families move across state lines after an initial custody and support order is entered. The case confirms that a receiving state can assert comprehensive jurisdiction — over both custody and financial matters — once all parties have relocated there, and that jurisdictional reservations in the original out-of-state judgment do not constrain the new forum’s discretion. Family law practitioners handling multi-state custody matters should note that the court coordinated directly with its California counterparts before asserting jurisdiction, a practice that both reinforced the legitimacy of Missouri’s authority and avoided conflicting orders.
The decision also reaffirms Missouri’s evidentiary harmless-error standard in custody proceedings: the exclusion of a witness’s testimony will not warrant reversal when the substance of that testimony was introduced through other witnesses. Parties seeking to preserve error on evidentiary rulings must demonstrate not only that the ruling was wrong, but that the excluded evidence would have meaningfully changed the outcome — a high bar when multiple witnesses have already addressed the same facts.
