Massachusetts Divorce Laws (2026): Grounds, Residency, and Process

Massachusetts allows divorce on a no-fault ground called "irretrievable breakdown of the marriage," available as either a joint 1A petition (both spouses agree) or a unilateral 1B complaint. The one-year residency requirement applies only when the cause of the divorce arose outside Massachusetts; a plaintiff domiciled in Massachusetts whose cause arose in-state can file without waiting a year, and no prior separation period is required.

Grounds for divorce in Massachusetts

Massachusetts recognizes both no-fault and fault-based divorce. The no-fault ground is "irretrievable breakdown of the marriage," which means the marriage has broken down permanently with no reasonable expectation of reconciliation. You do not have to prove anyone did anything wrong.

There are two no-fault paths. A 1A divorce requires both spouses to file a joint petition, along with a signed separation agreement covering property, alimony, and custody. A 1B divorce is filed unilaterally when one spouse wants a divorce but the other does not agree, or the parties cannot reach a full settlement at the time of filing.

Fault grounds are still available under M.G.L. c.208, sec. 1: adultery, cruelty and abusive treatment, utter desertion for one year, habitual intoxication or drug addiction, nonsupport, and impotency. Pursuing a fault ground can affect alimony and property division in some cases, but most Massachusetts divorces proceed on the no-fault ground.

Residency requirement

Massachusetts residency turns on where the cause of the divorce arose, not on a flat one-year rule. Under M.G.L. c.208, sec. 5, if the cause occurred outside the commonwealth, the plaintiff (the spouse who files) must have lived in Massachusetts for one year immediately before the action is commenced. If instead the plaintiff is domiciled in Massachusetts when the action is commenced and the cause occurred within Massachusetts, no one-year period applies at all.

Two details matter. The requirement attaches to the plaintiff, not to "you or your spouse," so it is the filing spouse's residence or domicile that counts. And under either path, a divorce will not be granted if it appears the plaintiff moved into Massachusetts for the purpose of obtaining a divorce.

Divorce is filed in the Probate and Family Court for a county where one of the parties lives, but M.G.L. c.208, sec. 6 adds a mandatory exception that catches many filers: if either party still resides in the county where the parties last lived together, the action must be heard and determined in a court for that county. The court with jurisdiction can transfer the case to another county if either party would face hardship or inconvenience.

Waiting period and separation

Massachusetts uses a nisi period, which is different from a separation requirement. A nisi period is a mandatory pause after the judge issues the divorce judgment before it becomes final. You do not have to live apart before you file.

For a 1A (joint) divorce, M.G.L. c.208, sec. 1A sets no minimum interval between filing and the hearing. It directs the opposite, that the petition be given a speedy hearing. The statutory periods run from the hearing forward instead: the court must make its finding on irretrievable breakdown within 30 days of the hearing, and a judgment of divorce nisi enters automatically 30 days after the court gives its initial approval to the agreement. The 90-day nisi period under M.G.L. c.208, sec. 21 then runs before the divorce becomes absolute. So the roughly 120-day floor is measured from the court's approval, not from the date of filing.

For a 1B (unilateral) divorce, M.G.L. c.208, sec. 1B requires that no hearing take place and no judgment of divorce nisi be entered until at least six months after the complaint is filed. After that hearing (and trial if needed), a 90-day nisi period runs after the judgment, so the statutory floor for a 1B divorce is roughly nine months from filing to finality, not counting any additional time a contested case takes to reach trial.

There is no requirement to live separately before filing. The nisi period protects parties who may reconcile after judgment, since either spouse can move to rescind the divorce within that window.

How property is divided

Massachusetts is an equitable distribution state, not a community property state. That means marital property is divided fairly based on the circumstances of the marriage, but "fairly" does not automatically mean 50/50. The court has broad discretion.

Under M.G.L. c.208, sec. 34, the judge considers the length of the marriage, each spouse's contributions (including homemaking), the age and health of each party, the amount and sources of income, vocational skills, employability, liabilities, and the needs of any dependent children. The statute lets the judge assign to either spouse "all or any part of the estate of the other," regardless of whose name is on the title and regardless of when the asset was acquired.

That reach is wider than many readers expect. Massachusetts has no statutory separate-property category, so assets owned before the marriage or received as a gift or inheritance are part of the divisible estate rather than automatically shielded. Judges frequently leave such assets with the spouse who brought them in, especially in shorter marriages, but that is a discretionary outcome under the section 34 factors, not a protection the statute guarantees. If property division is contested, you will need detailed financial disclosures, and a judge will decide based on the factors above.

Alimony, custody, and child support

Alimony, child custody, and child support are decided as part of the divorce process in Massachusetts. In a 1A divorce, the parties resolve all these issues in their separation agreement before filing. In a 1B divorce, the court decides any unresolved issues at trial.

Massachusetts reformed its alimony law significantly with the Alimony Reform Act of 2011. The type and duration of alimony (general term, rehabilitative, reimbursement, or transitional) depends on the length of the marriage and each spouse's financial need.

How to file for divorce in Massachusetts

Step 1: Confirm residency. If the cause of the divorce arose outside Massachusetts, the spouse who files must have lived in the state for one year before filing. If that spouse is domiciled in Massachusetts and the cause arose here, no one-year period applies. Note that section 5 bars a divorce where the plaintiff moved into the state in order to obtain one.

Step 2: Choose the right path. If you and your spouse have reached a full agreement on all issues, a 1A joint petition is faster. If not, file a 1B unilateral complaint.

Step 3: File in the right court. File in the Probate and Family Court for a county where one of you lives, except that if either spouse still resides in the county where you last lived together, the case must be heard in that county. Pay the filing fee (fees vary by court; check with the Probate and Family Court in your county for the current amount).

Step 4: Serve the other spouse. In a 1B case, you must serve the complaint and summons on your spouse according to Massachusetts rules of civil procedure. In a 1A case, both spouses file together, so formal service is not required.

Step 5: Exchange financial disclosures. Both parties must file a Financial Statement (short or long form depending on income) with the court. Full disclosure is required; hiding assets can expose you to sanctions.

Step 6: Attend hearings and negotiate. A 1A divorce requires one hearing where the judge reviews and approves the separation agreement. A 1B divorce may require pretrial conferences and, if issues remain unresolved, a trial before a judge.

Step 7: Receive the judgment nisi. The judge enters the judgment nisi. The 90-day nisi period then runs. After that period, the divorce is absolute (final) unless one spouse files to rescind.
