Modifies provisions relating to the custody and support of children

HB 2043 revises Missouri's child custody and support laws by replacing three existing statutes with new provisions. It requires courts to consider specific factors when setting support, including the child's needs, parents' finances, custody arrangements, and work-related childcare costs. The bill adds that support payments may be reduced or paused if a parent voluntarily gives up custody for over 30 consecutive days. It also extends parental support obligations until age 22 for children in secondary school or vocational/college programs (if enrolled full-time and making progress), or for incapacitated children beyond age 18.
