HB 3110 Missouri House · 2026 Regular Session

Provides that the court shall not order a parent to pay child support to the other parent for reasonable or necessary expenses of the child if the parents are awarded equal time with the child

HB 3110 would change how child support is calculated when parents share equal physical custody. Specifically, it requires courts to stop or reduce child support payments for any period exceeding 30 consecutive days that a child spends with the parent who would otherwise pay support, if the other parent voluntarily gave up custody. This directly affects parents in divorce or custody cases with near-equal time-sharing arrangements. The bill does not eliminate support entirely but automatically adjusts payments based on actual custody time, rather than requiring separate court orders for each custody period. This change aims to align support obligations more closely with the actual time each parent spends caring for the child.
