Massachusetts Divorce Laws (2026): Grounds, Residency, and Process
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. You must have lived in Massachusetts for at least one year before filing, 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
To file for divorce in Massachusetts, you must have lived in the state for at least one year immediately before filing. An exception applies if the cause for the divorce arose in Massachusetts and both spouses last lived together in Massachusetts; in that case you may file without satisfying the one-year period (M.G.L. c.208, sec. 5).
Divorce is filed in the Probate and Family Court in the county where either party lives. If you file jointly, you may use the county where either spouse resides.
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, the court schedules a hearing at least 30 days after filing. Once the judge approves the agreement, there is an additional 90-day nisi period before the divorce is final, making the fastest possible timeline roughly 120 days from the date of filing.
For a 1B (unilateral) divorce, the case proceeds through hearings (and trial if needed), and a 90-day nisi period runs after the judgment. A contested 1B case typically takes considerably longer because the court must schedule hearings and, if unresolved, a 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 court may assign any asset acquired during the marriage, regardless of whose name is on the title.
Separate property (assets owned before marriage, or received as a gift or inheritance and kept separate) may be shielded, but Massachusetts courts have discretion to reach premarital assets in longer marriages. 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. Make sure you or your spouse has lived in Massachusetts for at least one year, or that the cause of the divorce arose in Massachusetts while you both lived there.
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 in the county where either spouse resides. 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.
