In Montana, Child Support orders may be established by the District Court, or by the Montana Child Support Services Division (CSSD) of the Montana Department of Health & Human Services.  Individuals who receive public assistance are automatically referred to CSSD. Individuals who do not receive public assistance may apply for CSSD services.  A court may also direct the parties to work with CSSD.

District Courts and CSSD follow Montana laws (MCA) and Administrative Rules governing both parents’ duty of support to a child. Amounts are determined to be reasonable or necessary for the child's support, and without regard to marital misconduct. Relevant factors include:

  • the financial resources of the child;
  • the financial resources of the parents;
  • the standard of living that the child would have enjoyed had the marriage not been dissolved;
  • the physical and emotional condition of the child and the child's educational and medical needs;
  • the age of the child;
  • the cost of day care for the child;
  • any parenting plan that is ordered or decided upon; and
  • the needs of any person, other than the child, whom either parent is legally obligated to support.
