Massachusetts Alimony Statute: Types, Formula, and Deviations

Massachusetts alimony law caps general term payments at 30 to 35 percent of the income gap between spouses and ties how long the payments last to how long the marriage lasted. These rules come from the Alimony Reform Act of 2011, codified at M.G.L. c. 208, §§ 48–55, and apply to divorces finalized after March 2012, including modifications of older orders.

The Four Types of Alimony

Massachusetts recognizes four distinct categories, each built for a different situation.¹ The one a court picks depends on the length of the marriage, the recipient’s financial position, and what the support is meant to accomplish.

General Term Alimony

This is periodic support paid to an economically dependent former spouse and is by far the most common form. It applies when one spouse has an ongoing need and the other has the ability to pay.² Duration is capped by marriage length, and the amount follows the 30-to-35-percent formula.

Payments end automatically if the recipient remarries or either spouse dies. They can be suspended, reduced, or terminated if the recipient lives with a romantic partner for at least three continuous months.³ Payments also typically end when the paying spouse reaches full retirement age under Social Security, unless the court finds the recipient still cannot support themselves.¹

Rehabilitative Alimony

Rehabilitative alimony is temporary support for a spouse expected to become self-sufficient within a foreseeable timeframe — finishing a degree, completing job training, or building enough work experience to earn a living. Payments cannot last more than five years.⁴

An extension beyond five years is possible but requires “compelling circumstances.” The recipient must show unforeseen events prevented self-sufficiency despite genuine effort, and that the payor can continue paying without undue hardship. Rehabilitative alimony ends on remarriage or the death of either spouse.

Reimbursement Alimony

Reimbursement alimony compensates a spouse for financial contributions that directly benefited the other’s career or education. The classic case: one spouse worked to put the other through medical school, and the marriage ended shortly after. It is limited to marriages of five years or less.¹

Unlike the other forms, this one is about fairness rather than ongoing need, and the 30-to-35-percent income formula does not apply.⁵ It can be paid as a lump sum or in installments. Once ordered, neither party can seek a modification, and it ends only on the recipient’s death or a set end date. Remarriage and cohabitation do not end it.

Transitional Alimony

Transitional alimony helps a spouse adjust to the financial upheaval of divorce — relocation costs, setting up a new household, bridging a gap. It is available only after marriages lasting five years or less, cannot last longer than three years from the divorce date, and cannot be modified, extended, or replaced with a different form of alimony.⁶ It ends on the recipient’s death or the date set in the order.

How the Payment Amount Is Calculated

For general term alimony, the payment generally should not exceed whichever is less: the recipient’s actual financial need, or 30 to 35 percent of the difference between the two spouses’ gross incomes at the time the order is issued.⁷ If one spouse earns $150,000 and the other earns $50,000, the income gap is $100,000, and alimony would typically fall between $30,000 and $35,000 per year.

Income for this calculation follows the same definition used in the Massachusetts child support guidelines, which covers wages, salaries, tips, commissions, bonuses, and most other forms of compensation. Two categories are excluded:

Capital gains, dividends, and interest from assets that were already split between the spouses in the property division.
Any gross income the court already factored into a child support order.

That second exclusion drives how alimony and child support interact. The court calculates child support first, then removes that income from the alimony equation. This prevents double-counting, but it also means a large child support obligation can significantly reduce the alimony amount.⁸

How Long Alimony Lasts

The Alimony Reform Act ties the maximum duration of general term alimony directly to the length of the marriage:⁹

5 years or less: no longer than half the number of months the marriage lasted.
5 to 10 years: no more than 60 percent of the months of the marriage.
10 to 15 years: no more than 70 percent of the months of the marriage.
15 to 20 years: no more than 80 percent of the months of the marriage.
More than 20 years: the court has discretion to order indefinite alimony.

In concrete terms: a 12-year marriage falls in the 10-to-15-year bracket, so alimony could last up to 70 percent of 144 months, roughly 100 months, or about eight and a half years. Even marriages exceeding 20 years do not guarantee indefinite alimony; the court still evaluates whether indefinite support is warranted on the facts.

General term alimony also typically ends when the paying spouse reaches full retirement age as defined by the Social Security Administration. The payor can petition to terminate or reduce payments at that point, though the court retains the ability to continue alimony if the recipient shows a compelling ongoing need.¹

What the Court Weighs Before Ordering Alimony

Before setting a dollar amount, a judge first decides whether alimony is appropriate at all. The starting point is whether one spouse is “economically dependent” on the other, the statutory basis for general term alimony.² From there the court weighs each spouse’s income, employment history, and earning capacity; what each person contributed economically and domestically; and whether one spouse left the workforce or delayed a career to raise children or support the household.⁸

Age and health matter. A spouse with a chronic illness or disability that limits work is more likely to receive support, and for a longer period. The court also considers each spouse’s ability to maintain a lifestyle reasonably close to what existed during the marriage, balanced against the payor’s ability to support two households.

One rule catches people off guard. The “length of the marriage” is measured from the wedding date to the date the divorce complaint is served, not when the divorce is finalized. If the couple lived together and shared finances before the wedding, a judge can extend the marriage length to include that cohabitation period, which directly affects both amount and duration.

When a Judge Can Deviate From the Formula

The duration caps and the 30-to-35-percent formula are guidelines, not absolute ceilings. For general term and rehabilitative alimony, a judge can order a different amount or duration if specific circumstances justify it. Statutory grounds include:⁸

Either spouse is elderly or has a chronic illness or unusual health condition.
The parties’ tax situations make a strict application of the formula inequitable.
The paying spouse is providing and paying for health insurance or court-ordered life insurance for the recipient.
The paying spouse has significant investment income, annuities, or capital gains from assets not transferred to the recipient in the property division.
The couple lived together and shared finances for a long period before marrying.
The recipient cannot support themselves because of physical or mental abuse by the paying spouse.
The recipient has no property, no prospects for employment, and no other means of support.

The judge can also deviate for “any other factor the court considers relevant,” provided the reasoning is set out in a written explanation. That requirement means a deviation has to be grounded in something specific.

Two rules protect the payor after the initial order. If the paying spouse remarries, the new spouse’s income and assets cannot be used in an alimony modification proceeding. And income from a second job or overtime that started after the original order is presumed irrelevant to modification, so a spouse who picks up extra work should not be penalized with a higher obligation.¹⁰

Changing or Ending an Order

General term alimony can be modified in either amount or duration when there is a “material change of circumstances,” a legal standard requiring more than a minor fluctuation.³ Common examples: a substantial job loss, a major health event, a significant increase in the recipient’s income, or new financial obligations that genuinely change the picture. The court reviews updated financial statements from both sides.

Cohabitation is one of the most litigated triggers. If the recipient has lived with a romantic partner for at least three continuous months, the paying spouse can move to reduce or end alimony. The court looks at whether the couple shares finances, splits expenses, and functions as economic partners. Once cohabitation is shown, the burden shifts to the recipient to demonstrate that alimony is still necessary.

Some forms of alimony are more resistant to change than others. Reimbursement and transitional alimony cannot be modified at all once ordered. Rehabilitative alimony can be modified in amount during the support period based on a material change of circumstances, and can be extended beyond five years only if the recipient proves compelling circumstances, genuine effort toward self-sufficiency, and that the payor can afford to continue.⁴

If the Paying Spouse Doesn’t Pay

When a payor falls behind, the recipient can file a contempt complaint in the Massachusetts Probate and Family Court.³ The paying spouse must explain the missed payments and bears the burden of proving inability to comply.¹¹

When a judge finds civil contempt, the available remedies escalate quickly. The court can order jail time stayed on condition of corrective action, full payment of arrears, structured repayment covering current support plus a set amount toward arrears, a mandatory job search with reporting to a probation officer, or automatic wage withholding. Liens can be placed on real property and bank accounts. In severe cases, professional licenses, driver’s licenses, and passports can be suspended. Willful nonpayment can also be prosecuted as criminal contempt, which carries fines and incarceration independent of the civil process.

Taxes, Health Insurance, and Bankruptcy

For divorce or separation agreements finalized after December 31, 2018, alimony payments are neither deductible by the payor nor counted as income for the recipient.¹² Older agreements finalized before 2019 follow the prior rules — the payor deducts and the recipient reports the income — unless a later modification specifically adopts the new tax treatment. Under current law, a dollar of alimony costs the payor a full dollar and gives the recipient a full dollar.

Divorce is a qualifying event under COBRA, so a former spouse covered under the payor’s employer plan can elect to continue that coverage for up to 36 months, though at full unsubsidized cost.¹³ A Massachusetts court can treat that cost as a basis for deviating from the standard formula when the payor is covering the recipient’s insurance.

Alimony is a domestic support obligation under federal bankruptcy law and cannot be discharged in either Chapter 7 or Chapter 13.¹⁴ If the payor files for bankruptcy, the alimony obligation survives, and overdue alimony is treated as a priority debt in Chapter 13. Property settlement obligations — for example, a hold-harmless clause on a joint credit card — can be treated differently, so how each obligation is labeled in the divorce judgment matters if bankruptcy ever enters the picture.
