Massachusetts Family Law: Divorce, Custody, Support, and Alimony

Massachusetts family law covers marriage, divorce, child custody, child support, alimony, property division, and abuse prevention orders, and almost all of it runs through the Probate and Family Court. Two features set the state apart from most others. Judges here can divide any property either spouse owns, including assets one spouse brought into the marriage or inherited. And Massachusetts is one of only two states (with Vermont) that has not adopted the Uniform Child Custody Jurisdiction and Enforcement Act, which matters any time a custody case crosses state lines.¹ The sections below walk through the parts of the system most people need to understand.

How Divorce Works in Massachusetts

A divorce begins with a complaint filed in the Probate and Family Court. The filing fee is $200 plus a $15 surcharge, with small additional costs for the citation ($15) or summons ($5) needed to serve the other spouse.²

Most divorces are no-fault, filed on the ground of irretrievable breakdown of the marriage.³ There are two routes:

A 1A divorce is filed jointly when both spouses agree on all terms and submit a signed separation agreement.
A 1B divorce is filed by one spouse when the other does not agree or the couple cannot settle their issues.

Fault grounds also remain on the books under Chapter 208, Section 1: adultery, desertion for at least one year, habitual intoxication, cruel and abusive treatment, and gross refusal to provide support when able. Fault cases need evidence and tend to be more expensive to litigate, though proven fault can affect how the judge divides property or sets alimony.⁴

The Nisi Period and Timeline

Timing surprises many people. In a 1A case, the judge issues a judgment nisi after the hearing, and that judgment does not become final for 120 days. In a 1B case, the court cannot hold a hearing until at least six months after filing, and the judgment nisi then becomes final 90 days later.⁵⁶

During that nisi period you are still legally married. You cannot remarry. Changes to health insurance, beneficiary designations, and other arrangements that depend on marital status may not take effect until the divorce is absolute. Courts encourage mediation and settlement throughout the case, and many contested matters resolve before trial.

Child Custody

Massachusetts courts decide custody based on the happiness and welfare of the child, the standard set out in Chapter 208, Section 31. The law starts from the position that both parents have equal rights and asks which arrangement best supports the child’s stability, relationships, and daily needs.⁷

Two kinds of custody can each be sole or shared. Legal custody governs major decisions about the child’s education, health care, and religious upbringing. Physical custody determines where the child lives. Joint legal custody is common when parents can communicate and cooperate. Evidence of domestic violence or abuse weighs heavily against the abusive parent.

Modifying a custody order requires proof of a material and substantial change in circumstances, like a parent’s relocation disrupting the child’s schooling or a significant shift in a parent’s living situation. Either parent can file a complaint for modification; the filing fee for a modification of child-related issues is $50.²

When Parents Were Never Married

Chapter 209C governs custody for unmarried parents, and one default rule matters more than any other: before paternity is legally established, the birth parent has sole custody. The other parent has no custodial rights until a court adjudicates paternity or the parents file a voluntary acknowledgment.⁸

Once paternity is established, either parent can seek custody. The court applies a best-interests standard similar to the one used in divorce cases but also looks at who served as the primary caretaker and where the child has lived in the six months before the case was filed. Joint custody is awarded only if the parents have a written agreement or the court finds they have already been sharing parental responsibilities successfully.

Custody Across State Lines

Because Massachusetts has not adopted the UCCJEA, interstate custody questions here are governed by the Massachusetts Child Custody Jurisdiction Act, codified in Chapter 209B. The basic framework is similar: the child’s home state, where the child has lived for six months before the case is filed, generally has jurisdiction. But the procedural differences from the UCCJEA used by nearly every other state can create complications, and interstate custody is one of the areas where consulting an attorney pays off.¹

Child Support

Child support is calculated under the Massachusetts Child Support Guidelines, updated periodically by the Trial Court. The most recent version took effect on December 1, 2025. The formula considers each parent’s gross weekly income, the number of children, health insurance costs, child care expenses, and any other existing support obligations.⁹

Each parent’s share of the combined support obligation is proportional to their share of combined available income. A judge can deviate from the guidelines when applying them would be unjust in the specific circumstances, but must explain the reasoning. Orders remain in effect until the child turns 18, or up to 23 if the child is still financially dependent and enrolled in an educational program.

Unpaid support is collected by the Department of Revenue’s Child Support Enforcement Division, which has broad authority: income withholding, intercepting state and federal tax refunds, liens on property, bank account seizures, suspending driver’s and professional licenses, credit bureau reporting, and contempt actions that can carry jail time.¹⁰

Changing a support order requires a material change in circumstances. Modification filings involving child support, custody, or parenting time cost $50.²

Alimony

The Alimony Reform Act of 2011 rebuilt how Massachusetts courts award spousal support, creating four categories and imposing durational caps that did not exist before.¹¹

General term alimony: ongoing support for a spouse who is economically dependent; duration tied to the length of the marriage.
Rehabilitative alimony: support while a spouse gains skills, education, or employment needed to become self-sufficient.
Reimbursement alimony: compensation for contributions one spouse made to the other’s education or career in a short marriage.
Transitional alimony: short-term help for a spouse adjusting to a different lifestyle or location after the marriage ends.

Amount and Duration

The amount generally should not exceed the recipient’s need, or 30 to 35 percent of the difference between the spouses’ gross incomes. Judges weigh age, health, income, employability, each spouse’s contributions (including as a homemaker), and the lifestyle maintained during the marriage.¹²

General term alimony is also capped by the length of the marriage:

5 years or less: no longer than half the number of months of the marriage.
More than 5 up to 10 years: no more than 60 percent of the months.
More than 10 up to 15 years: no more than 70 percent.
More than 15 up to 20 years: no more than 80 percent.
Over 20 years: the court may order alimony for an indefinite period.

A judge can deviate from these limits by making written findings that the interests of justice require a longer duration.¹³

When Alimony Ends

General term alimony automatically terminates when the recipient remarries or either spouse dies. It also terminates when the paying spouse reaches full Social Security retirement age, unless the court specifically orders otherwise at the time of the original judgment, or later grants an extension based on clear and convincing evidence of changed circumstances.

Cohabitation is another trigger. If the paying spouse shows that the recipient has maintained a common household with another person for at least three continuous months, the court may suspend, reduce, or terminate alimony. Factors include whether the couple shares living expenses, presents themselves as a couple to others, and functions in collaborative domestic roles. If the cohabitation relationship later ends, the original alimony obligation can be reinstated, but it will not extend past its original termination date.¹³

Property Division

Massachusetts is an equitable distribution state, but with a broader definition of divisible property than most. Under Chapter 208, Section 34, a judge can assign “all or any part of the estate of the other” spouse. In plain terms, that means everything either spouse owns is potentially on the table: assets acquired before the marriage, inherited property, and gifts included. The court is not limited to dividing only what was earned or purchased during the marriage.¹⁴

This is where Massachusetts surprises people. If you owned a home before the marriage or inherited money from a parent, a judge has the legal authority to award some or all of it to your spouse. In practice the source and timing of an asset influence how it is divided, but discretion is broad. Factors the court considers include:

Length of the marriage
Conduct of the parties during the marriage
Age, health, and occupation of each spouse
Income, employability, and vocational skills of each spouse
Each spouse’s contribution to acquiring, preserving, or increasing the value of the estate, including contributions as a homemaker
Each spouse’s opportunity to acquire future income and assets
The present and future needs of any dependent children

Divisible property includes real estate, retirement accounts, pensions, profit-sharing plans, deferred compensation, business interests, and insurance benefits. The court can order sales to achieve a fair result or assign specific assets to one spouse and offset the value elsewhere.

Retirement Accounts and QDROs

Dividing an employer-sponsored plan like a 401(k) or pension requires a Qualified Domestic Relations Order, or QDRO. The QDRO directs the plan administrator to pay a portion of benefits to the non-participant spouse. Without one, the administrator has no obligation to split the account, and early withdrawal penalties or taxes could apply if funds are moved improperly.¹⁵

Military retirement follows different rules under the Uniformed Services Former Spouses’ Protection Act. The maximum paid directly to a former spouse from military retired pay is 50 percent of disposable income, and the combined cap rises to 65 percent when property division is being collected alongside child support or alimony.¹⁶

Abuse Prevention Orders

Chapter 209A provides a fast, accessible process for obtaining a protective order against domestic abuse. A 209A order can protect anyone who has been abused by a family member, household member, or someone they are or were dating. You can file at any Probate and Family Court, district court, or superior court. If the court is closed, you can request an emergency order from a police officer, who contacts an on-call judge.¹⁷

A court can issue an emergency (ex parte) order the same day you file, without the other person present, if there is an immediate risk of harm. That temporary order lasts until a full hearing, typically scheduled within 10 business days. At the hearing, both sides present evidence and the judge decides whether to extend the order for up to a year. Orders can be renewed annually.

A 209A order can require the abuser to stay away, leave a shared home, have no contact with you or your children, pay temporary support, and surrender firearms. Violating a 209A order is a criminal offense. The order also matters in custody cases, because the judge must consider evidence of abuse when deciding custody and visitation.

Federal Firearm Consequences

A 209A order has larger consequences than many people realize. Under 18 U.S.C. § 922(g), anyone subject to a qualifying domestic violence protection order is prohibited from possessing firearms. Separately, a conviction for a misdemeanor crime of domestic violence permanently bars firearm possession under the Lautenberg Amendment, with no exception for law enforcement officers or military personnel.¹⁸

A Massachusetts 209A order is enforceable in every other state under 18 U.S.C. § 2265, which requires all states to give full faith and credit to protection orders issued by other jurisdictions. The order does not need to be registered elsewhere to be enforceable.¹⁹

Tax, Insurance, and Social Security After Divorce

Alimony and Taxes

For any divorce or separation agreement finalized after December 31, 2018, alimony is not deductible by the payer and is not taxable income to the recipient. If your divorce was finalized before 2019, the old treatment (deductible for the payer, taxable for the recipient) still applies unless the agreement was later modified to expressly adopt the new rules. Child support is never deductible and never counted as income, regardless of when the agreement was signed.²⁰

Claiming Children as Dependents

After divorce, the custodial parent (the one the child lives with for the greater number of nights during the year) is generally entitled to claim the child as a dependent. If nights are equal, the parent with the higher adjusted gross income gets the claim. The custodial parent can release the dependency claim by signing IRS Form 8332, which allows the noncustodial parent to claim the child tax credit. Head-of-household filing status and the earned income credit stay with the custodial parent regardless.²¹

Health Insurance

If you are covered under your spouse’s employer-sponsored plan, divorce is a qualifying event for COBRA continuation coverage. You have 60 days after the divorce to notify the plan administrator, who then has 14 days to provide enrollment information. COBRA for a divorced spouse can last up to 36 months, but you pay the full premium (both the employer and employee shares) plus a possible 2 percent administrative fee.²² Section 34 also lets a Massachusetts judge order the paying spouse to maintain health insurance for the other as part of an alimony order, and to extend, obtain, or reimburse the cost of coverage.

Social Security After a Long Marriage

If your marriage lasted at least 10 years, you may collect Social Security benefits based on your former spouse’s work record once you turn 62. You must be currently unmarried, and the benefit on your own record must be less than what you would receive on your ex-spouse’s record. Your claim does not reduce your former spouse’s benefits. If your ex has not yet filed but is at least 62, you can still file on their record as long as you have been divorced for at least two years.²³

Getting Married in Massachusetts

Both partners must appear together at any city or town clerk’s office to apply for a marriage license. You do not need to apply in the town where you live or plan to hold the ceremony. Each person brings valid photo ID (passport, driver’s license, or state ID), a Social Security number, and payment for the license fee, which varies by municipality but commonly runs around $50.²⁴

After you file the application, there is a mandatory three-day waiting period before you can pick up the license. If you need it sooner, you can file a Marriage Without Delay form with the probate or district court in the town where you submitted the application and ask a judge to waive the wait. That court filing carries its own fee of $180 plus a $15 surcharge.²⁵

Massachusetts does not require a blood test or state residency, so out-of-state couples can marry here. The marriage must be solemnized by an authorized officiant, such as a justice of the peace, a member of the clergy, or a person granted a one-day designation by the governor. You must be at least 18 unless you have parental consent and court approval.

Special Situations

Service Members

The Servicemembers Civil Relief Act protects active-duty military members involved in family law cases. If military duties prevent a member from appearing in court, the court must grant a stay of at least 90 days on a proper request that includes a letter from the member’s commanding officer. The protection applies to divorce, custody, and support proceedings and prevents default judgments against someone who cannot appear because of active service.²⁶

Bankruptcy

Child support and alimony cannot be discharged in bankruptcy. Federal law classifies them as domestic support obligations and gives them the highest priority during bankruptcy proceedings, meaning they are paid before almost all other debts. If a former spouse files for bankruptcy, your support order remains fully enforceable. Property division orders are also generally non-dischargeable, though the analysis is more complex and depends on the chapter filed.

Annulment

Annulment is a narrow alternative to divorce, available only when a marriage is void (bigamy, incest) or voidable (lack of capacity, impotence unknown to the other spouse, underage without the required permission, or fraud going to the essence of the marriage). It requires more evidence than a no-fault divorce, and courts interpret fraud grounds narrowly.²⁷ If an annulment is not available on these grounds, divorce is the route.
