Child Support Services Division (CSSD) of the Montana Department of Public Health and Human Services

“The mission of the Child Support Enforcement Division (CSED) of the Montana Department of Public Health and Human Services is to diligently pursue and ultimately achieve financial and medical support of children by establishing, enforcing, and increasing public awareness of parental obligations.

The division provides federally mandated child support enforcement services. These include:

  • Locating absent parents
  • Establishing paternity
  • Establishing financial and medical support orders
  • Enforcing current and past-due child support
  • Offering medical and spousal support
  • Modifying child support orders

Administrative decisions of the division can be appealed through judicial review by a district court.” — CSSD


Montana’s child support laws are designed to ensure that children receive the financial support they need from both parents. The Montana Department of Revenue is responsible for enforcing child support orders and collecting payments.

If you are a parent who is owed child support, you can contact the Montana Department of Revenue to help you collect the payments you are owed. The department can help locate the non-custodial parent, establish paternity, and set up or enforce a child support order.

If you are a non-custodial parent who is struggling to make your child support payments, the Montana Department of Revenue can help you with payment plans or other options. It is important to keep up with your child support payments, as failure to do so can result in wage garnishment, tax refund interception, or even jail time.

If you have any questions about Montana’s child support laws or how to set up or enforce a child support order, you can contact the Montana Department of Revenue for help. Be sure to check out our resources and child support calculator below.

Are Your Additional Expenses Being Managed?

Did you know that state systems only manage base child support payments & do not provide a way for parents to manage transactions & make payments for additional child expenses such as medical, education, child care or any other child-related expenses? Even if you have your base payments coming thru the state you need a solution to manage, track & pay all your child expenses – while providing a complete history & record.

SupportPay was built to help parents manage all child support & expenses while working with state payment systems.
