Alimony in Massachusetts: how it works, what it costs, and how long it lasts

Last updated 2026-07-09

What is alimony in Massachusetts and what law governs it?

Alimony in Massachusetts is a court-ordered payment from one spouse to the other after a divorce. The point is economic. It eases the transition for a spouse who earns less, either because of time out of the workforce, a wide income gap, or both.

The law that runs the show is the Massachusetts Alimony Reform Act of 2011, which took effect March 1, 2012 ^[1]. Before that act, Massachusetts alimony was open-ended and there was no consistent formula. The reform changed all of it. It created four alimony types, tied duration caps to the length of the marriage, capped the amount at a percentage of the income difference, and wrote automatic termination events into the statute.

Divorcing in Massachusetts now means this is the framework your agreement or your judge will use. General term alimony is what most people picture when they say "alimony." The other three types (rehabilitative, reimbursement, and transitional) solve narrow problems in narrow situations, and you want to know the difference before you sign anything.

For how alimony works across the country, see our general alimony overview.

What are the 4 types of alimony in Massachusetts?

Massachusetts General Laws Chapter 208, Section 48 defines all four types ^[1]. Here's how each one works in practice.

General term alimony is ongoing support paid by the higher earner to the spouse with a substantially lower income. It's the default for marriages with a real income gap where the lower earner needs time to rebuild. Duration is capped (that's the next section), and the amount can change if circumstances do.

Rehabilitative alimony supports a recipient who's expected to become self-sufficient through school, job training, or getting back into the workforce. It runs no more than 5 years, no matter how long the marriage lasted ^[1]. Courts use it when the road to self-support is clear but takes time.

Reimbursement alimony is a one-time or fixed payment that pays back a spouse who financially supported the other through education or a career jump. Picture one spouse putting the other through medical school, then the marriage ends soon after. That's what reimbursement alimony addresses. It's available only for marriages of 5 years or less ^[1].

Transitional alimony helps a spouse adjust to a new lifestyle or a new location after a short marriage. It also applies only to marriages of 5 years or less and runs no more than 3 years ^[1].

General term alimony gets litigated the most. If your marriage ran longer than 5 years and one of you earned a lot more, that's almost certainly your category.

How long does alimony last in Massachusetts?

General term alimony has hard duration caps written into the statute. The longer the marriage, the longer alimony can run, but there's always a ceiling ^[1].

Marriage length	Maximum alimony duration
Up to 5 years	Up to 50% of the number of months married
5 to 10 years	Up to 60% of the number of months married
10 to 15 years	Up to 70% of the number of months married
15 to 20 years	Up to 80% of the number of months married
20+ years	Indefinite (no statutory cap)

Quick math: a 12-year marriage caps general term alimony at about 8.4 years (70% of 144 months).

Indefinite doesn't mean permanent. Even past 20 years, the court can set a term, and general term alimony ends automatically when the recipient remarries, either spouse dies, or the payor reaches full Social Security retirement age as defined by federal law ^[1]. That retirement trigger is new since the reform act, and it carries weight. Full Social Security retirement age is 67 for anyone born in 1960 or later ^[2].

Courts can also reduce or suspend general term alimony if the recipient lives with a new partner in a "common household" for at least three continuous months, under M.G.L. c. 208, Section 49(d) ^[1]. That cohabitation provision gets fought over regularly.

Rehabilitative alimony caps at 5 years. Reimbursement alimony has no time limit but is fixed and can't be modified. Transitional alimony caps at 3 years.

How much alimony will a Massachusetts court award?

The statute sets a ceiling, not a floor. General term alimony "should generally not exceed the recipient's need or 30 to 35 per cent of the difference between the parties' gross incomes" at the time of the order, under M.G.L. c. 208, Section 53(b) ^[1].

That 30-35% band gives judges room, but the need cap matters just as much. Say the lower earner's monthly expenses run $3,000, and 35% of the income difference would come out to $4,500. The court won't order $4,500.

What counts as gross income here? Courts use a broad definition: wages, self-employment income, investment income, rental income, and other recurring sources. It tracks closely with the income definition in the Massachusetts child support guidelines, though it isn't identical ^[3].

Beyond the percentage cap, judges weigh 13 statutory factors when setting the actual amount ^[1]:

1. Length of the marriage 2. Age of each spouse 3. Health of each spouse 4. Income, employment, and employability of each spouse 5. Economic and non-economic contributions of each spouse to the marriage 6. Marital lifestyle 7. Lost economic opportunity as a result of the marriage (a spouse who left a career, for example) 8. Ability of each spouse to maintain the marital lifestyle 9. Available sources of each spouse's income 10. Opportunity for future asset acquisition 11. Premarital cohabitation that preceded the marriage 12. Conduct of the parties during the marriage (fault is a factor, though courts use it sparingly) 13. The tax consequences to each party

One note on taxes. Federal law changed in 2019. Under the Tax Cuts and Jobs Act, alimony paid under agreements finalized after December 31, 2018 is no longer deductible by the payor or taxable to the recipient ^[4]. Older agreements (pre-2019) can still follow the old rules. This is real money and it shapes how you negotiate the number.

Does Massachusetts consider fault when awarding alimony?

Yes, but it's complicated. Fault (adultery, abuse, abandonment) is one of the 13 statutory factors, so a judge is allowed to weigh it. In practice, Massachusetts courts don't apply fault mechanically. Most judges give it limited weight unless the conduct hurt the other spouse economically.

The clearest case where fault moves the needle is economic misconduct. If the higher earner hid assets or ran up debt, the court may award more generous support. If the lower earner damaged the marital estate, that can cut the other way.

Massachusetts allows no-fault divorce under M.G.L. c. 208, Sections 1A and 1B ^[5], and most divorces run that way. Filing no-fault doesn't erase evidence of conduct, though. Someone can still raise it at a hearing.

If fault and alimony are genuinely contested, working with a divorce attorney is the practical call. If you and your spouse agree on everything, a no-fault uncontested divorce is far simpler and cheaper.

Can alimony be modified or terminated in Massachusetts?

General term alimony and rehabilitative alimony can both be modified. Reimbursement alimony can't, once it's ordered. Transitional alimony can't be modified either ^[1].

To modify a modifiable award, the moving party has to show a material change in circumstances since the last order. Courts look at a real income change, involuntary job loss, a serious health change, or the recipient moving in with a new partner.

Cohabitation deserves its own flag. Under M.G.L. c. 208, Section 49(d), a court can reduce, suspend, or terminate alimony if the recipient lives with another person in a common household for three or more continuous months ^[1]. The payor has to file a complaint for modification and prove the cohabitation, and that fight can get expensive on its own.

Automatic termination events for general term alimony:

• The recipient remarries
• Either spouse dies
• The payor reaches full Social Security retirement age ^[1]

Notice the asymmetry. The recipient's cohabitation can reduce alimony, but only remarriage ends it automatically. Living with a partner long-term without remarrying doesn't end alimony on its own. It opens the door to seek modification.

What's the process for setting alimony in an uncontested Massachusetts divorce?

If you and your spouse agree on alimony, you write it into your separation agreement. That agreement goes to the court with your divorce papers, and once the judge approves it, it becomes a court order.

For a 1A (joint petition) no-fault divorce, you file together and hand in your separation agreement at the same time. There's a 30-day wait after the hearing before the judgment becomes absolute (called a judgment nisi), then another 90 days before it's final ^[5]. Filing to final judgment runs about four months at a minimum.

For a 1B (unilateral) no-fault divorce, one spouse files, there's a waiting period before a hearing can be scheduled, then the same post-hearing wait before the judgment is final ^[5].

The filing fee for a Massachusetts divorce is $215 at the Probate and Family Court ^[6]. That covers the base case. If your separation agreement is ready and nothing is contested, you generally don't need a lawyer, though paying one to review the agreement before you sign is money well spent.

DivorceClear's $149 document packet includes the Massachusetts forms and a separation agreement template with an alimony clause you fill in, which fits when you and your spouse already agree on terms.

The Massachusetts Probate and Family Court runs a self-help center with forms and instructions at mass.gov ^[6]. Use it. It's genuinely good, and the forms there are the official versions.

How does Massachusetts handle alimony and child support together?

When there's a child support order too, alimony gets figured on the income that's left after child support. The Massachusetts Child Support Guidelines say alimony and child support should be set in coordination so one doesn't swallow the other ^[3].

In practice, judges usually set child support first under the guidelines, then look at alimony based on the remaining income difference. Child support is modifiable on its own. Alimony is separate.

Want a child support estimate? The state runs an online calculator built on the current guidelines ^[3]. That figure feeds straight into any alimony talk.

Parenting issues and money issues are related but distinct. See our piece on the child support calculator if you're working both at once.

What does Massachusetts alimony cost to litigate or negotiate?

Filing fees at the Probate and Family Court are $215 ^[6]. Same price whether you're fighting over alimony or not.

Cost explodes in legal fees. A contested alimony hearing in Massachusetts can pull in financial affidavits, subpoenas for tax returns and pay stubs, expert witnesses on earning capacity, and repeat court appearances. Attorney rates in the Boston area commonly run $250 to $450 an hour at mid-market firms, consistent with the American Bar Association's reporting on legal fees, though regional variation is real ^[7]. A fully contested alimony fight can cost each spouse $10,000 to $30,000 or more.

An agreed separation agreement with terms you negotiated yourselves costs $215 in court fees plus whatever you spend on document prep. That's the whole argument for settling.

Some couples hire a mediator to reach agreement before filing. Massachusetts has court-connected mediation programs and private mediators. Mediation typically runs $150 to $350 per hour, and most alimony mediations wrap in two to four sessions ^[8].

Honest version: if you and your spouse are close on numbers, spending $500 to $1,000 on mediation to close the gap beats litigating almost every time.

How does Massachusetts alimony affect taxes after the 2018 tax law change?

People miss this one until it's too late.

For divorce agreements finalized on or after January 1, 2019, alimony payments are no longer deductible by the payor and no longer taxable income to the recipient, under the Tax Cuts and Jobs Act of 2017 ^[4]. That change is permanent.

For agreements signed before December 31, 2018, the old rules still apply: payor deducts, recipient reports as income, as long as the agreement hasn't been modified in a way that adopts the new rules ^[4].

Why does it matter for negotiation? Under the old rules, a $3,000 monthly payment cost a payor in the 32% bracket about $2,040 after the deduction. Under the new rules, it costs the full $3,000. That's a big gap, and it means the gross number in a post-2018 agreement has to be thought about differently.

If you're writing your own separation agreement, run the after-tax math before you settle on a number. The IRS lays out the alimony rules in plain language in Publication 504 at irs.gov ^[4].

What happens to alimony if the payor retires or loses income?

The Alimony Reform Act addressed retirement head-on. General term alimony ends automatically when the payor reaches full Social Security retirement age ^[1]. That age is 66 for people born between 1943 and 1954, rising in steps to 67 for anyone born in 1960 or later ^[2].

Retire early, before full retirement age, and it's a different story. The payor has to file a complaint for modification and show a material change in circumstances. Voluntary early retirement doesn't automatically cut alimony, and courts have discretion. Some judges are sympathetic. Others impute income based on what the payor could still earn.

Involuntary job loss is a cleaner case for modification. If the payor loses a job, they can ask for a temporary order reducing or suspending payments during the search. Wait too long to file and arrears pile up. In Massachusetts, alimony arrears accrue interest at 12% per year ^[9].

The practical move: file a modification complaint the moment circumstances change materially. Don't wait, and don't stop paying without a court order cutting your obligation.

Is a prenuptial or postnuptial agreement binding on alimony in Massachusetts?

Yes, with conditions. Massachusetts courts enforce prenuptial and postnuptial agreements on alimony when they meet the standard requirements: full financial disclosure, no coercion, and a genuine chance for both parties to review with independent counsel ^[10].

The Supreme Judicial Court set the modern standard for postnuptial agreements in Ansin v. Craven-Ansin, 457 Mass. 283 (2010), holding that such agreements are enforceable when they were fair and reasonable at execution and remain fair and reasonable at the time of divorce ^[10].

"Fair and reasonable at the time of divorce" is the escape valve. If enforcing the agreement would leave one spouse eligible for public assistance, courts have found it unconscionable. That's uncommon, but it happens.

Got a prenup or postnup that covers alimony? Fold it into your separation agreement process and make sure your decree references it. If you're waiving alimony rights by agreement in your divorce, the court will examine whether that waiver was knowing and voluntary.

Where do you actually file alimony paperwork in Massachusetts?

Divorce and alimony in Massachusetts go through the Probate and Family Court. There are 14 divisions, one in each county ^[6]. You file in the county where either spouse lives.

The forms you need for an uncontested divorce with an alimony agreement:

• CJ-D 101 (Joint Petition for Divorce, for 1A) or CJ-D 110 (Complaint for Divorce, for 1B)
• Financial Statement (Short or Long Form, depending on income)
• Separation Agreement (your drafted agreement, signed by both parties)
• R-408 Certificate of Absolute Divorce (completed after judgment)

Every official Massachusetts Probate and Family Court form is available at mass.gov ^[6]. The court's self-help center pages are the best free resource in the state for DIY filers.

Frequently asked questions

How long do you have to be married to get alimony in Massachusetts?

There's no minimum marriage length to be eligible for alimony in Massachusetts. But for marriages of 5 years or less, only reimbursement or transitional alimony is available, not general term. Rehabilitative alimony caps at 5 years regardless of marriage length. The longer the marriage, the longer general term alimony can run, up to indefinite for marriages over 20 years.

Does Massachusetts have a formula for calculating alimony?

There's a cap, not a precise formula. General term alimony can't exceed the recipient's need or 30 to 35 percent of the difference between the parties' gross incomes, under M.G.L. c. 208, Section 53(b). Within that ceiling, judges weigh 13 statutory factors. Unlike child support, no worksheet spits out a number. The 30-35% band gives courts discretion.

Does a spouse's adultery affect alimony in Massachusetts?

It can, but usually only modestly. Fault is one of the 13 statutory factors a judge considers. Massachusetts courts generally don't award dramatically higher or lower alimony over adultery alone unless the conduct caused direct economic harm to the marriage. A spouse who drained marital assets to fund an affair faces a different calculus than one who simply had an affair.

Can I waive alimony in a Massachusetts divorce settlement?

Yes. Both spouses can agree to waive alimony entirely in their separation agreement, and courts will honor that waiver if it's knowing, voluntary, and not unconscionable. Use clear language stating each party waives any right to alimony, past, present, and future. Courts occasionally refuse to enforce a waiver that would leave a spouse needing public assistance, but that's uncommon.

What happens to alimony if the recipient starts working or earns more money?

The payor can file a complaint for modification at the Probate and Family Court and show a material change in circumstances, specifically that the recipient's income rose substantially. The court can reduce or terminate alimony if the recipient is now closer to or at self-sufficiency. Earning more doesn't cut alimony automatically. You need a new court order.

Does alimony end in Massachusetts when the recipient lives with someone new?

Not automatically. Under M.G.L. c. 208, Section 49(d), cohabitation in a common household for at least three continuous months gives the payor grounds to seek modification, reduction, or suspension of alimony. The payor has to file a complaint for modification and prove the cohabitation. Only remarriage automatically terminates alimony.

Is alimony taxable income in Massachusetts?

For agreements signed after December 31, 2018, alimony is not taxable income to the recipient and not deductible by the payor at the federal level under the Tax Cuts and Jobs Act. For agreements signed before that date, the old rules still apply unless the agreement was modified to adopt the new treatment. Massachusetts generally conforms to federal tax treatment for alimony.

What is the difference between alimony and a property settlement in Massachusetts?

Alimony is ongoing income support, paid periodically. A property settlement is a one-time division of assets and debts. They do different jobs: property division is about what you own, alimony is about ongoing income needs. Reimbursement alimony is the type closest to a property settlement in concept, but it's still categorized as support, not equitable division under M.G.L. c. 208.

Can alimony be included in an uncontested Massachusetts divorce?

Yes, and it's common. If both spouses agree on the amount and duration, you include the alimony terms in your separation agreement and file it with your divorce papers at the Probate and Family Court. The judge reviews the agreement for fairness. As long as it's reasonable, the court approves it and folds it into the divorce judgment, making it an enforceable court order.

How do Massachusetts courts calculate alimony when one spouse is self-employed?

Courts look at actual income shown on tax returns plus any expenses run through the business that personally benefit the owner. If a self-employed spouse under-reports income, the judge can impute income based on earning capacity, prior earnings, and industry standards. A forensic accountant, or at minimum a review of three to five years of tax returns, is standard in contested cases involving self-employment.

What court handles alimony in Massachusetts?

The Probate and Family Court handles all divorce and alimony matters in Massachusetts. There are 14 county divisions. You file in the county where you or your spouse currently lives. The court's self-help centers at mass.gov provide official forms and instructions for self-represented filers.

Can alimony be paid as a lump sum in Massachusetts?

Yes. Parties can agree to a lump-sum payment in place of periodic alimony, and courts can order it. A lump sum fully settles the alimony obligation and generally can't be modified later. It can be attractive when one spouse wants a clean financial break. The tax treatment differs from periodic alimony, so run the numbers carefully before you agree to a lump-sum structure.
