Montana Child Support Enforcement Division

Child Support · Montana · Free

State agency that establishes paternity, opens child support orders, enforces payments, modifies obligations when income changes, and processes interstate cases for Montana parents. Custodial and non-custodial fathers can open a case online or by phone; bring the other parent's information, income records, and any existing orders. Modification requires a substantial change in circumstances — job loss, new parenting time, or disability.
