Start with G.L. c. 208 §§ 49, 53 (Alimony Reform Act). In Massachusetts, A material change of circumstances since the judgment (§ 49(e)). Reaching full retirement age is presumptively a material change allowing modification or termination for general term alimony (§ 49(f)); extensions beyond the durational cap require clear and convincing evidence. That is the question this guide answers for modifying alimony. Reimbursement alimony is expressly non-modifiable; parties may opt out of the Act’s provisions by written agreement. General term alimony terminates on the payor reaching full retirement age (presumptively), the recipient’s remarriage, or death of either party. Cohabitation (maintenance of a common household) for at least three months suspends, reduces, or terminates alimony (§ 49(d)).
The legal standard in Massachusetts
A material change of circumstances since the judgment (§ 49(e)). Reaching full retirement age is presumptively a material change allowing modification or termination for general term alimony (§ 49(f)); extensions beyond the durational cap require clear and convincing evidence.
Courts start from the decree, not from scratch. The judge asks what the parties and the court knew when alimony was set, what has changed since, and whether the change is significant and durable enough to make the existing terms unreasonable. The moving party carries the burden, and documentation — tax returns, pension statements, medical records, lease agreements — decides most of these cases.
Grounds that most often succeed
- Retirement. Many states now treat reaching full retirement age as a presumptive or statutory ground. Early or voluntary retirement is scrutinized: courts ask whether it was in good faith, whether it was foreseeable at divorce, and whether the recipient had a chance to save.
- Involuntary income loss. Layoffs, business failure, disability, or industry collapse — with proof of diligent job-seeking. Voluntary underemployment is commonly met with income imputation instead of relief.
- The recipient's changed need. Improved earnings, remarriage-adjacent cohabitation, an inheritance, or reduced expenses.
- Health changes. New disability or extraordinary medical costs on either side.
- Cohabitation. General term alimony terminates on the payor reaching full retirement age (presumptively), the recipient’s remarriage, or death of either party. Cohabitation (maintenance of a common household) for at least three months suspends, reduces, or terminates alimony (§ 49(d)).
Grounds that rarely work: a new partner's income without statutory cohabitation, ordinary inflation, the payor's new family expenses standing alone, or a temporary dip in earnings.
How the Massachusetts rule applies
Apply the Massachusetts authorities in order. The facts are simplified so the statute and the standard are visible.
A former spouse in Massachusetts asks to change periodic alimony after retirement or a drop in income.
- File a complaint for modification filed in the Probate and Family Court.
- Match the facts to the Massachusetts standard: A material change of circumstances since the judgment (§ 49(e)). Reaching full retirement age is presumptively a material change allowing modification or termination for general term alimony (§ 49(f)); extensions beyond the durational cap require clear and convincing evidence.
- Check whether this award can be modified at all: Reimbursement alimony is expressly non-modifiable; parties may opt out of the Act’s provisions by written agreement.
- If the request is to end support, prove a trigger: General term alimony terminates on the payor reaching full retirement age (presumptively), the recipient’s remarriage, or death of either party. Cohabitation (maintenance of a common household) for at least three months suspends, reduces, or terminates alimony (§ 49(d)).
Prospective from the modification complaint; accrued alimony cannot be cancelled. The forum is the Probate and Family Court that entered the judgment, or the Department of Revenue (DOR) Child Support Enforcement Division.
Cohabitation and remarriage
General term alimony terminates on the payor reaching full retirement age (presumptively), the recipient’s remarriage, or death of either party. Cohabitation (maintenance of a common household) for at least three months suspends, reduces, or terminates alimony (§ 49(d)).
Cohabitation cases are intensely fact-driven: shared finances, shared household expenses, the relationship's public character, and its duration all matter. Massachusetts procedure requires proof — surveillance or speculation is not enough, and the recipient gets discovery and a hearing before payments stop. Until a court order issues, keep paying.
Step-by-step: how to file
- Read the decree and any incorporated agreement. Reimbursement alimony is expressly non-modifiable; parties may opt out of the Act’s provisions by written agreement. Confirm the court retained jurisdiction to modify.
- Confirm the forum. Modification goes to a complaint for modification filed in the Probate and Family Court. If a party has moved away, UIFSA and registration rules determine where the petition belongs.
- Gather evidence dated to the change. Termination notices, disability awards, pension and Social Security statements, tax returns, medical records, or evidence of the recipient's cohabitation.
- File and serve promptly. Prospective from the modification complaint; accrued alimony cannot be cancelled.
- Exchange financial disclosure. Many courts require updated financial affidavits; self-employment cases often add forensic accounting or a vocational expert.
- Seek temporary relief if needed. Where circumstances are dire, ask the court for interim reduction or suspension pending the full hearing — Massachusetts judges can grant temporary remedies in appropriate cases.
- Litigate, mediate, or stipulate. A settlement must be reduced to an order and entered before payment obligations change.
When the change takes effect
Prospective from the modification complaint; accrued alimony cannot be cancelled.
The corollary: unilaterally reducing or stopping payments before an order issues builds arrears, interest, and contempt exposure — even if you ultimately win the modification.
Awards that cannot be modified (or are hard to change)
Reimbursement alimony is expressly non-modifiable; parties may opt out of the Act’s provisions by written agreement.
Common traps:
- Lump-sum or property-division awards styled as alimony are usually final when entered.
- Agreement language that waives modification binds the parties even though the statute would allow a petition.
- Expired terms — once a fixed term lapses, most states will not revive it; a timely pre-expiration motion is critical.
- Jurisdiction reservations — in some states, if the decree did not expressly reserve jurisdiction to modify, no later court can.

Frequently asked questions
Can alimony be modified in Massachusetts?
Yes, in most cases. A material change of circumstances since the judgment (§ 49(e)). Reaching full retirement age is presumptively a material change allowing modification or termination for general term alimony (§ 49(f)); extensions beyond the durational cap require clear and convincing evidence.
Does retirement end alimony in Massachusetts?
Retirement is a recognized ground in Massachusetts — G.L. c. 208 §§ 49, 53 (Alimony Reform Act) governs how courts weigh it. Reaching normal retirement age carries more weight than early or voluntary retirement, and the recipient's own retirement readiness is considered.
Does my ex's cohabitation stop alimony?
General term alimony terminates on the payor reaching full retirement age (presumptively), the recipient’s remarriage, or death of either party. Cohabitation (maintenance of a common household) for at least three months suspends, reduces, or terminates alimony (§ 49(d)). You must petition the court and prove the statutory elements — the obligation does not end by operation of the new relationship alone until a judge so orders (unless Massachusetts's statute makes termination automatic on remarriage).
Can alimony be increased?
Yes, where the statute permits. Recipients who prove a material increase in need — often medical — can seek upward modification, subject to the payor's ability to pay.
Can Massachusetts courts modify alimony retroactively?
Prospective from the modification complaint; accrued alimony cannot be cancelled.
What if my alimony was set by agreement?
Reimbursement alimony is expressly non-modifiable; parties may opt out of the Act’s provisions by written agreement. Agreements matter: read the incorporated terms before assuming a petition will be heard on ordinary changed-circumstances grounds.
