Massachusetts Alimony Law Overview

Massachusetts Alimony Reform Act (2011) significantly restructured alimony. General term alimony is capped at 30-35% of the difference in gross incomes. Duration is strictly capped by statute based on marriage length. Alimony terminates at the payor's full Social Security retirement age.

Formula & Calculation Approach

Amount: generally should not exceed 30-35% of the difference in the parties' gross incomes. Duration caps: marriages under 5 years = max 50% of months married; 5-10 years = 60%; 10-15 years = 70%; 15-20 years = 80%; 20+ years = indefinite.

Duration Rules in Massachusetts

Strictly capped: under 5yr = up to 50% of duration; 5-10yr = 60%; 10-15yr = 70%; 15-20yr = 80%; 20+ yr = indefinite but terminates at payor's Social Security retirement age.
