Alimony Child Support in Montana
In Montana, child support and spousal maintenance (alimony) are governed by separate statutes with distinct rules. Child support obligations are calculated under Mont. Code Ann. § 40-4-204, using a formula that considers parental income and certain expenses; the Montana Child Support Guidelines, found at Mont. Admin. R. 37.62.106 et seq., provide the specific calculation method. Spousal maintenance, governed by Mont. Code Ann. § 40-4-203, is determined based on factors set out in the statute and may be ordered for a fixed duration. The worked example below demonstrates how the child support formula applies to a typical case.
