Massachusetts caps alimony duration at 50% to 80% of the length of the marriage under the Alimony Reform Act of 2011, codified at M.G.L. c. 208, § 49. A 10-year marriage, for example, produces a maximum alimony obligation of 6 to 7 years (60-70% of the marriage duration). Only marriages exceeding 20 years may result in indefinite alimony, and even then the court retains discretion to set a fixed term. Alimony amounts are generally capped at 30-35% of the difference between the spouses' gross incomes under M.G.L. c. 208, § 53, though post-2019 tax changes have shifted the practical range to approximately 22-28%.

How Long Does Alimony Last in Massachusetts Under the Reform Act
Massachusetts alimony duration is determined by statutory caps tied directly to the length of the marriage, as established by the Alimony Reform Act of 2011. A marriage lasting 12 years produces a maximum general term alimony obligation of approximately 8.4 years (70% of 144 months). These caps apply to general term alimony only and represent the maximum duration a court may order without issuing a written deviation finding.
The durational limits under M.G.L. c. 208, § 49 break down into five tiers:
| Marriage Length | Maximum Alimony Duration | Example: Months Married → Months of Alimony |
|---|---|---|
| 5 years or less | 50% of months married | 48 months married → 24 months alimony |
| More than 5, up to 10 years | 60% of months married | 96 months married → 57.6 months alimony |
| More than 10, up to 15 years | 70% of months married | 156 months married → 109.2 months alimony |
| More than 15, up to 20 years | 80% of months married | 228 months married → 182.4 months alimony |
| More than 20 years | Indefinite (court discretion) | Court may still set a fixed term |
Marriage length is measured from the date of the marriage to the date of service of the divorce complaint. Massachusetts courts count the actual number of months, not rounded years. A marriage of 9 years and 11 months falls within the 60% tier, while a marriage of 10 years and 1 month moves into the 70% tier. This distinction can mean a difference of several years in the alimony obligation.
Courts may deviate beyond these durational limits only upon a written finding that deviation is "required in the interests of justice" under M.G.L. c. 208, § 49(b). In practice, judicial deviation is uncommon and typically requires extraordinary circumstances such as a recipient spouse's serious disability or a payor's concealment of assets.
Four Types of Alimony in Massachusetts
Massachusetts recognizes four distinct categories of alimony under M.G.L. c. 208, § 48, each with different duration rules, eligibility requirements, and purposes. General term alimony is the most commonly awarded type and accounts for the vast majority of alimony disputes in Massachusetts Probate and Family Courts.
General Term Alimony
General term alimony provides periodic payments to a spouse who is economically dependent on the other. Massachusetts courts award general term alimony when one spouse earns significantly more than the other and the lower-earning spouse cannot maintain a reasonable standard of living independently. The durational caps in M.G.L. c. 208, § 49 apply exclusively to general term alimony. A recipient spouse must demonstrate economic need, and the amount cannot exceed 30-35% of the difference between the parties' gross incomes under M.G.L. c. 208, § 53.
Rehabilitative Alimony
Rehabilitating alimony provides periodic payments for a defined period while the recipient spouse acquires education, training, or work experience needed to become self-supporting. Massachusetts courts commonly award rehabilitative alimony when one spouse left the workforce during the marriage and needs 2-5 years to complete a degree or professional certification. Rehabilitative alimony is not subject to the same percentage-of-marriage durational limits as general term alimony, giving courts greater flexibility to match the award duration to the actual rehabilitation timeline.
Reimbursement Alimony
Reimbursement alimony compensates a spouse who made significant economic or noneconomic contributions to the other spouse's financial resources during a marriage of 5 years or less. Massachusetts courts award reimbursement alimony when one spouse supported the other through graduate school, medical residency, or professional licensing, and the marriage ended before both spouses could benefit from the resulting increased earning capacity. Reimbursement alimony may be paid in periodic installments or as a one-time lump sum.
Transitional Alimony
Transitional alimony helps a spouse adjust to a changed lifestyle or relocate following a divorce after a marriage of 5 years or less. Massachusetts courts award transitional alimony for a fixed period, typically 6-18 months, to cover relocation costs, temporary housing expenses, or other immediate post-divorce needs. Transitional alimony cannot exceed 3 years in duration and terminates automatically upon the recipient's remarriage or cohabitation.
How Massachusetts Courts Calculate Alimony Amounts
Massachusetts courts calculate alimony using a statutory income-based formula that limits the award to 30-35% of the difference between the spouses' gross incomes under M.G.L. c. 208, § 53. A payor earning $200,000 annually and a recipient earning $60,000 annually face a gross income difference of $140,000, producing a maximum alimony range of $42,000 to $49,000 per year ($3,500 to $4,083 per month). The Tax Cuts and Jobs Act of 2017, which eliminated the federal alimony tax deduction effective January 1, 2019, has compressed the practical range to approximately 22-28% of the income difference in most cases.
Massachusetts courts must also consider the 15 factors listed in M.G.L. c. 208, § 53(a), including:
- Length of the marriage
- Age and health of both parties
- Income, employment, and employability of both spouses
- Economic and noneconomic contributions to the marriage
- Marital lifestyle and ability of each party to maintain it
- Lost economic opportunity resulting from the marriage
- Property division under M.G.L. c. 208, § 34
- Ability of each party to provide for themselves
The 2024 decision in Openshaw v. Openshaw clarified that a recipient's "need" for alimony can include the ability to accumulate savings after divorce, provided regular savings was part of the established marital lifestyle. Massachusetts courts are not required to limit alimony to covering only basic living expenses.
When Does Alimony End in Massachusetts: Termination Events
General term alimony in Massachusetts terminates automatically upon three specific events under M.G.L. c. 208, § 49: the death of either spouse, the remarriage of the recipient spouse, or the payor spouse reaching full Social Security retirement age. The payor's full retirement age is determined under the Old-Age, Survivors, and Disability Insurance (OASDI) program, which is currently age 67 for individuals born after 1960.
Remarriage of the Recipient
Massachusetts law terminates general term alimony automatically when the recipient spouse remarries. Under M.G.L. c. 208, § 49(c), alimony cannot be reinstated after remarriage unless the parties have an express written agreement providing for reinstatement. This is a significant change from pre-Reform Act law, which allowed courts to reinstate alimony in limited circumstances.
Cohabitation
Massachusetts courts may suspend, reduce, or terminate general term alimony when the recipient spouse cohabitates with another person in a common household for a continuous period of at least 3 months under M.G.L. c. 208, § 49(d). Cohabitation does not automatically terminate alimony — the payor must file a complaint for modification and prove the living arrangement constitutes a "common household" with shared finances, shared expenses, or a relationship analogous to marriage.
Payor Reaching Retirement Age
General term alimony terminates when the payor reaches full Social Security retirement age under M.G.L. c. 208, § 49(f). For individuals born after 1960, full retirement age is 67. Massachusetts courts cannot order alimony to continue beyond the payor's full retirement age absent a written deviation finding based on clear and convincing evidence that deviation is required in the interests of justice.
Material Change in Circumstances
Either spouse may petition to modify or terminate alimony based on a material change in circumstances under M.G.L. c. 208, § 37. Common grounds include job loss, significant income reduction (typically 25% or more), disability, or the recipient spouse's substantial increase in income. Massachusetts courts require the change to be both material and permanent, not temporary or voluntary.
How the Cavanagh Decision Changes Alimony in 2026
The Massachusetts Appeals Court's 2025 ruling in Cavanagh v. Cavanagh fundamentally changed how Massachusetts courts calculate alimony when child support is also at issue. Massachusetts courts must now run calculations twice — once computing alimony first and then child support, and once computing child support first and then alimony — and compare after-tax outcomes to determine which order produces the most equitable result for both parties.
Before Cavanagh, Massachusetts courts routinely calculated child support first and then determined alimony from the remaining income, effectively reducing alimony awards in cases involving minor children. The Cavanagh three-step process applies to all new divorce cases and modifications filed after the decision. The December 2025 update to the Massachusetts Child Support Guidelines expressly incorporates this methodology and raised the maximum combined parental income threshold from $400,000 to $450,000 per year.
Massachusetts Divorce Filing Requirements
Massachusetts requires a spouse to be domiciled in the Commonwealth at the time of filing if the grounds for divorce arose within the state under M.G.L. c. 208, § 4. A spouse whose grounds for divorce arose outside Massachusetts must have lived continuously in the Commonwealth for at least 1 year immediately prior to filing. Massachusetts law prohibits filing for divorce if the person moved to the state solely for the purpose of obtaining a divorce.
The filing fee for a divorce complaint in Massachusetts is $305, which includes the complaint filing fee ($215), summons surcharge ($15), and additional court surcharge ($90). As of March 2026. Verify with your local clerk. Additional costs may include a constable or sheriff service fee of $50-$75 for contested (1B) divorces and an e-filing processing fee of $22 for joint (1A) petitions filed electronically.
Massachusetts offers two no-fault divorce paths:
- 1A Joint Petition: Both spouses file together with a separation agreement. The court holds a hearing approximately 30 days after filing, and the judgment becomes final (nisi) 90 days after the hearing, then absolute 30 days later (total approximately 120-150 days).
- 1B Contested: One spouse files alone. A 6-month waiting period applies before the court schedules a hearing. Contested divorces in Massachusetts typically take 12-18 months from filing to final judgment.
Property Division and Its Effect on Alimony Duration
Massachusetts is an equitable distribution state where the court may divide all property owned by either spouse, including premarital assets, inheritances, and gifts, under M.G.L. c. 208, § 34. Massachusetts courts consider 15 factors when dividing property, including the length of the marriage, each spouse's age and health, income and employability, and contributions to the acquisition or preservation of assets.
Property division directly affects how long alimony lasts in Massachusetts because courts consider the overall financial picture when setting both the amount and duration of alimony. A recipient spouse who receives a larger share of marital assets — such as the marital home, retirement accounts, or investment portfolios — may receive a shorter alimony term or lower monthly payments. Massachusetts courts must avoid "double-dipping" by excluding income generated from equitably divided assets when calculating the alimony amount under M.G.L. c. 208, § 53(e).
Capital gains, dividends, and interest from equitably divided assets are excluded from the income calculation for alimony purposes. A recipient spouse who receives $500,000 in investment accounts generating $25,000 annually in dividends cannot claim that $25,000 as part of the income gap justifying alimony, and the payor's corresponding investment income is similarly excluded.
Modifying Alimony Duration After the Divorce
Either spouse may file a complaint for modification of alimony in the Massachusetts Probate and Family Court at any time during the alimony term under M.G.L. c. 208, § 37. Massachusetts courts require proof of a material change in circumstances that was not anticipated at the time of the original order. The filing fee for a modification complaint is $50, plus a $15 summons fee if service is required.
Common grounds for modifying alimony duration in Massachusetts include:
- Payor's involuntary job loss resulting in income reduction of 25% or more
- Recipient's significant increase in earned income
- Payor's serious illness or disability reducing earning capacity
- Recipient's cohabitation with a new partner for 3 or more continuous months
- Either party's retirement at or after full Social Security retirement age
- Recipient's completion of education or job training (for rehabilitative alimony)
Massachusetts courts cannot extend general term alimony beyond the statutory durational limits in M.G.L. c. 208, § 49 without a written finding that extension is required in the interests of justice. Parties may voluntarily agree to alimony terms that differ from the statutory guidelines, but such agreements must be approved by the court and are subject to the same modification standards.
Frequently Asked Questions
How long does alimony last in Massachusetts for a 10-year marriage?
Alimony for a 10-year marriage in Massachusetts lasts a maximum of 60-70% of the months of the marriage under M.G.L. c. 208, § 49. A marriage lasting exactly 10 years (120 months) falls in the 60% tier, producing a maximum alimony duration of 72 months (6 years). A marriage of 10 years and 1 month moves into the 70% tier, increasing the maximum to approximately 84.7 months.
Does alimony end when the recipient remarries in Massachusetts?
General term alimony terminates automatically upon the recipient's remarriage under M.G.L. c. 208, § 49(c). Alimony cannot be reinstated after remarriage unless the original agreement contains an express written reinstatement provision. Rehabilitative and reimbursement alimony may also terminate upon remarriage depending on the specific court order.
Can alimony last forever in Massachusetts?
Indefinite alimony is available in Massachusetts only for marriages exceeding 20 years under M.G.L. c. 208, § 49. Even in marriages longer than 20 years, the court retains discretion to set a fixed duration. Indefinite alimony still terminates upon the payor reaching full Social Security retirement age (currently 67 for those born after 1960), the recipient's remarriage, or either party's death.
What is the maximum alimony payment in Massachusetts?
Massachusetts caps alimony at the recipient's need or 30-35% of the difference between the spouses' gross incomes, whichever is less, under M.G.L. c. 208, § 53. Since the 2019 elimination of the federal alimony tax deduction, Massachusetts courts have practically adjusted awards to approximately 22-28% of the gross income difference in most cases.
Does cohabitation end alimony in Massachusetts?
Cohabitation does not automatically terminate alimony in Massachusetts. Under M.G.L. c. 208, § 49(d), the payor must prove the recipient has maintained a common household with another person for a continuous period of at least 3 months. The court may then suspend, reduce, or terminate alimony based on the financial impact of the cohabitation arrangement.
Can I waive alimony in a Massachusetts prenuptial agreement?
Massachusetts allows couples to waive alimony rights in a prenuptial agreement under the Massachusetts Uniform Premarital Agreement Act (M.G.L. c. 209, § 25). The agreement must be in writing, signed voluntarily by both parties, and accompanied by fair and reasonable disclosure of assets. Massachusetts courts may refuse to enforce an alimony waiver if enforcement would leave one spouse eligible for public assistance.
How does retirement affect alimony in Massachusetts?
General term alimony terminates when the payor reaches full Social Security retirement age under M.G.L. c. 208, § 49(f). For individuals born after 1960, full retirement age is 67. Early retirement does not automatically end alimony, but the payor may petition for modification based on reduced income. The retirement termination provision applies only to orders entered after March 1, 2012.
What is the difference between alimony and child support in Massachusetts?
Alimony supports a former spouse and is governed by M.G.L. c. 208, §§ 48-55, while child support provides for minor children under the Massachusetts Child Support Guidelines. Following the 2025 Cavanagh decision, Massachusetts courts must calculate both alimony and child support in two separate sequences and compare outcomes. The December 2025 Child Support Guidelines update raised the combined parental income cap from $400,000 to $450,000 per year.
How do I request alimony in a Massachusetts divorce?
A spouse requests alimony by including the request in the divorce complaint or by filing a separate motion for temporary alimony in the Probate and Family Court. The filing fee for a divorce complaint is $305 (complaint + summons + surcharges). Temporary alimony may be awarded within 30-60 days of filing under M.G.L. c. 208, § 17, while permanent alimony is determined at the final hearing or trial.
Does Massachusetts consider fault when awarding alimony?
Massachusetts courts may consider marital fault when determining alimony under M.G.L. c. 208, § 53(a). However, the Alimony Reform Act specifies that the "length of the marriage, need of the parties, and ability of the parties to maintain the marital lifestyle" carry the greatest weight. Adultery, cruel treatment, or abandonment may influence alimony only when those behaviors had a direct economic impact on the marital estate.
