Understanding Child Custody Laws in Missouri

Missouri courts determine all custody matters using the best interest of the child standard. This means the court evaluates each parent’s ability to provide a stable, nurturing environment, the child’s existing relationships and routines, and any special needs or preferences (for children old enough to express them).

Child support in Missouri is calculated using the Income Shares model. Both parents' incomes are combined, and the state's guideline table determines the total obligation. Each parent's share is proportional to their income.

Missouri recognizes both legal custody (decision-making authority) and physical custody (where the child lives). Joint legal custody is common; physical custody arrangements vary based on the family’s circumstances. The filing fee to initiate custody proceedings in Missouri is $135–$225.
