What Maine law says about spousal support
Plain-English summaries of Maine’s statute and court rules as of the date shown on each, with the quoted text. Not legal advice: laws change and courts apply them case by case.
Formula
Income difference × (years married × 0.015), factor max 0.3 — from Jan. 1, 2027
Presumptive annual general support equals the difference between the spouses’ spousal support incomes times a durational factor of 0.015 per year of marriage, with the factor capped at 0.3; it is figured yearly but may be paid monthly or weekly. A court may depart with written findings that it would be inequitable or unjust.[1]

Show statute text
“There is a rebuttable presumption that the annual amount of any general support awarded under this paragraph must equal the difference in the parties' spousal support incomes multiplied by a durational factor that is calculated by multiplying the number of years of the marriage by 0.015, except that the durational factor may not exceed 0.3.”
Formula
Applies to actions pending on or after January 1, 2027
The 2026 amendments (Public Law 2025, chapter 571, approved March 19, 2026) apply to all actions pending on or after January 1, 2027; for older awards, the new presumption cannot itself be the substantial change that justifies a modification.[2]
