How Montana calculates child support
Montana calculates child support using the Melson Formula, which starts with each parent's self-support reserve (basic living needs) before computing the child support obligation. This approach ensures neither parent falls below subsistence while providing for the children.
State-specific details including deviation factors, modification procedures, and enforcement rules are available through the official Montana child support agency.
