What alimony is (and is not)

Alimony is court-ordered support from one spouse to the other after separation or divorce. It is separate from child support (see Mass. Child Support Guidelines; Mass. Gen. Laws c. 208, § 28) and from property division. A single judgment may include all three, but each has its own legal tests.

No spouse is automatically entitled to alimony. Courts typically ask whether one party has a genuine need and whether the other has the ability to pay, then apply Massachusetts's statutory framework.

Eligibility and statutory factors

General term alimony is generally capped at 30%–35% of the difference in the parties’ gross incomes arising from the marriage, subject to statutory exclusions and deviations.

Fault. Conduct is generally secondary; economic factors dominate under the Reform Act.

Document income, earning capacity, health, length of marriage, contributions as homemaker or to the other spouse's career, and the marital standard of living. Those facts drive both temporary (pendente lite) and final awards.

Types of alimony in Massachusetts

General term, rehabilitative, reimbursement, and transitional alimony.

Labeling matters. Rehabilitative awards usually require a plan (schooling, retraining, re-entry to the workforce). Durational or term awards run for a fixed period. Lump-sum or reimbursement awards may be non-modifiable depending on the judgment language and statute.

How amount is set

Because Massachusetts uses a formula or guideline overlay, start with that math, then test it against need, ability to pay, and any statutory caps. General term alimony is generally capped at 30%–35% of the difference in the parties’ gross incomes arising from the marriage, subject to statutory exclusions and deviations.

Temporary support while a divorce is pending often follows different local practices or guidelines than the final award. Confirm what your county or division actually uses.

How long alimony lasts

General term duration is capped by marriage-length formulas (e.g., percentages of marriage length for marriages under 20 years), with different rules for marriages of 20 years or more.

Permanent / indefinite support. Limited. For marriages of 20 years or longer, alimony may be indefinite, but still subject to modification and statutory termination events.

When alimony ends or can be changed

Death, remarriage, or cohabitation as defined by statute; reaching full Social Security retirement age for general term alimony in many cases.

Either party may usually seek modification upon a substantial change in circumstances unless the award was expressly made non-modifiable. Retirement, disability, remarriage, cohabitation, and large income swings are frequent triggers — but the statutory test and burden of proof are Massachusetts-specific.

Taxes

TCJA changed federal deductibility for post-2018 instruments; Massachusetts alimony calculations and deviations should be reviewed in light of nontaxable treatment.

Child support remains non-deductible and non-taxable. Do not assume alimony treatment mirrors child support.
