Massachusetts Divorce Laws: Residency, Waiting Period, Custody and Support

Generally, a Massachusetts divorce requires that the spouses lived together as a married couple in Massachusetts, and if the grounds arose in another state, that they had lived together in Massachusetts before that and one of them lived in Massachusetts when the grounds arose. Otherwise, the filing spouse must have lived in Massachusetts for one year before filing if the grounds arose outside the state, or must be domiciled in Massachusetts at filing if the grounds arose in the state. A divorce will not be granted if the filing spouse moved to Massachusetts just to get a divorce.

The no-fault ground is an irretrievable breakdown of the marriage, filed either jointly with an agreement (Section 1A) or by one spouse (Section 1B). Fault grounds are adultery, impotency, utter desertion for one year before filing, gross and confirmed habits of intoxication from alcohol or drugs, cruel and abusive treatment, and gross or cruel refusal to provide support by a spouse able to do so. A divorce can be granted even if both spouses have grounds.

Every divorce judgment is first a judgment nisi, which becomes absolute (final) 90 days after it is entered unless the court orders otherwise. In a joint no-fault case (Section 1A), the judgment nisi enters 30 days after the court approves the separation agreement, so the divorce is final about 120 days after approval. In a one-spouse no-fault case (Section 1B), the hearing cannot be held until at least six months after the complaint is filed, followed by the 90-day nisi period.

Spouses who agree can file a joint petition for divorce based on an irretrievable breakdown (Section 1A). They file a petition signed by both, a sworn affidavit that the marriage has irretrievably broken down, and a notarized separation agreement (which may be filed up to 90 days after the case starts); no summons or answer is needed. The court holds a hearing, decides whether the agreement makes proper provision for custody, support, alimony and property, and does not consider marital fault. These cases are placed on a separate, faster hearing list.

Massachusetts is an equitable distribution state. The court may assign to either spouse all or part of the other spouse's estate, including vested and nonvested retirement, pension and other benefits accrued during the marriage. The statute does not limit division to property acquired during the marriage. Factors include the length of the marriage, conduct during the marriage, each spouse's age, health, station, occupation, income, vocational skills, employability, estate, liabilities and needs, the opportunity of each to acquire future assets and income, any alimony, and the needs of dependent children. The court may also consider each spouse's contribution to acquiring, preserving or increasing the value of the estates, including as a homemaker.

Massachusetts has four types of alimony: general term (for an economically dependent spouse), rehabilitative (until a spouse is expected to become self-sufficient), reimbursement, and transitional (the last two only after marriages of 5 years or less). General term alimony is limited by the length of the marriage unless the court finds a longer term is required in the interests of justice: up to 50% of the months of marriage for marriages of 5 years or less, 60% for over 5 to 10 years, 70% for over 10 to 15 years, and 80% for over 15 to 20 years; it may be indefinite for marriages over 20 years. It ends when the recipient remarries or either spouse dies, may be reduced or ended if the recipient cohabits for 3 months or more, and generally ends when the payer reaches full Social Security retirement age. The amount should generally not exceed the recipient's need or 30 to 35 percent of the difference between the spouses' gross incomes. Factors include the length of the marriage, ages, health, income and employability, contributions, marital lifestyle, and lost economic opportunity.

Custody is decided by the happiness and welfare of the children, and the parents' rights are equal absent misconduct. The court considers whether the child's present or past living conditions harm the child's physical, mental, moral or emotional health. While the case is pending, parents generally have temporary shared legal custody unless there is an emergency, abuse or neglect, or the judge makes written findings that it is not in the child's best interest. At trial there is no presumption for or against shared legal or physical custody (except in certain abuse cases under Section 31A), and a parent seeking shared custody must submit a shared custody implementation plan. The statute does not set an age for the child's preference.

Child support is set under the Massachusetts Child Support Guidelines issued by the Chief Justice of the Trial Court. The guideline amount is presumed correct; a court may depart from it only with written findings that the guideline amount would be unjust or inappropriate and that the departure is in the child's best interests. Orders may be modified when the existing amount is inconsistent with the guideline amount.

Massachusetts does not use the term legal separation, but a married person may file a complaint for separate support in the Probate and Family Court if a spouse fails without justifiable cause to provide support, deserts them, or if they have justifiable cause to live apart. The court may order spousal support, decide custody and support of minor children, and prohibit the other spouse from restraining their personal liberty.

If the validity of a marriage is doubted, either spouse may file an action to annul it; it is started the same way as a divorce. A marriage performed in Massachusetts between close relatives (by blood or marriage) or while either party had a living spouse is void without any court judgment. A judgment of nullity for a marriage performed out of state requires that the filing spouse was domiciled in Massachusetts at the time of the marriage and at filing, or had lived in Massachusetts for five years before filing.

Grandparents may be granted reasonable visitation with an unmarried minor grandchild by the Probate and Family Court, on a written finding that it is in the child's best interest, if the parents are divorced, married but living apart, under a separate support order, if a parent has died, or if the parents were never married and do not live together (with paternity established, except when maternal grandparents are asking). Visitation is not available, and ends, if the child is adopted by someone other than a stepparent.

The court granting a divorce may allow a woman to resume her maiden name or the name of a former husband.

Child support orders cover minor children (under 18). The court may also order support, maintenance and education for a child aged 18 to 20 who lives in a parent's home and is principally dependent on that parent, and for a child aged 21 to 22 who lives in a parent's home and is principally dependent on that parent because the child is enrolled in an educational program (not including costs beyond an undergraduate degree).

The state child support agency (the IV-D agency, which by law is the Department of Revenue) can collect past-due support through income withholding notices to employers, demand letters, state and federal tax refund intercepts, federal administrative offset, passport denial, credit bureau reporting, contempt proceedings, capias and warrants, liens on real and personal property (unpaid support is automatically a lien), levy and seizure, forced sale of property, trustee process, and interception of unemployment and workers' compensation benefits, judgments, settlements and lottery winnings, bank accounts, and pension or retirement funds. It can also have driver's, professional, occupational, recreational and other licenses and vehicle registrations suspended, revoked or not renewed, after notice and a chance for a hearing. Each unpaid support payment becomes a judgment by law on its due date. The agency may assess interest and penalties by regulation.

After a divorce, either parent can file a complaint to modify. Support orders must be modified if the existing amount is inconsistent with the amount under the child support guidelines, or if health care coverage for the child needs to be provided for, unless the difference is due to an earlier justified departure from the guidelines that still applies. A parent's agreement does not prevent modification of child support. In cases where the state child support agency provides services, either parent can ask the agency to review the order every three years (or more often if regulations allow); within that cycle no change in circumstances needs to be shown, and outside it the requesting party must show a substantial change in circumstances. The agency must notify parents of this right at least once every three years.

Once a divorce or custody case is filed and until a judgment, parents have temporary shared legal custody unless there are emergency conditions, abuse or neglect, or the judge makes written findings that shared custody is not in the child's best interest and orders temporary sole legal custody. While a request to modify a divorce judgment is pending, either party (or a next friend for the children) can file a motion, with notice to the other party, for temporary orders about the children's care, custody and support; any temporary custody order must include specific findings showing the injury, harm or damage that could be expected if relief is not granted.

Both parties file a notice of intention to marry, under oath, with the clerk or registrar of any city or town in Massachusetts, on state forms that include a statement that there is no legal impediment to the marriage, and pay the town's fee. The notice must be filed at least three days before the marriage (Sundays and holidays count). The clerk issues the marriage certificate (license) on or after the third day and no later than 60 days after filing, and it must be returned if not used within 60 days of filing. A probate or district court judge may grant a certificate allowing the marriage without the three-day delay, and the delay can also be waived in emergencies such as imminent death. A party too ill to appear may have notice given on his or her behalf with a physician's affidavit.

A magistrate or minister may not perform a marriage if either party is under 18. The statute contains no exception for parental consent or court approval.

A person of full age may petition the probate court in the county where he or she lives to adopt a person younger than himself or herself (other than a spouse); a nonresident may petition in the county where the child lives. A married petitioner's spouse must join unless excused (for example, by prolonged absence, legal separation or incapacity) and the adoption is in the child's best interest. Written consent is required from a child over 12, the child's spouse, and the lawful parents (or the mother alone if the child was born outside marriage and no father is legally established); a parent's consent may be signed no sooner than the fourth day after birth and is final and irrevocable. For a child under 14, the Department of Children and Families investigates whether the child and the petitioners' home are suitable and reports to the court within 30 days. The court may dispense with consent when that is in the child's best interest under the statutory fitness factors.

A stepparent adopts through the same probate court petition; a minor may petition, or join a spouse's petition, to adopt the natural child of one of them. The court may waive the Department of Children and Families investigation and report when the petition is to adopt the child of one of the petitioners. The other legal parent's written consent is required unless the court dispenses with it because adoption without consent is in the child's best interest, considering factors such as abandonment, willful failure to visit or support, and parental unfitness.

The Probate and Family Court may appoint a guardian for a minor if the parents are deceased or incapacitated, consent, have had their parental rights terminated, have signed a voluntary surrender, or are found unavailable or unfit to have custody. A guardian named by a parent has priority. While a petition is pending, the court may appoint a temporary guardian for up to 90 days (extendable) to prevent substantial harm, with 7 days' notice to a minor 14 or older and to the persons named in the petition, unless an emergency justifies shortening or waiving notice.

The incapacitated person or anyone interested in his or her welfare may petition for a determination of incapacity and appointment of a limited or general guardian. The court may appoint a guardian only if it finds, among other things, that the person is incapacitated, that the appointment is necessary or desirable for continuing care and supervision, and that the person's needs cannot be met by less restrictive means, including appropriate technological assistance; any required medical certificate must be based on an examination within 30 days before the hearing. The court must encourage maximum self-reliance and independence and may limit the guardian's powers to create a limited guardianship.

The person who gave birth and the alleged genetic parent, presumed parent or intended parent may sign a written voluntary acknowledgment of parentage before a notary and file it with the registrar of vital records and statistics or with the court. Unless a signer rescinds within 60 days of signing, by filing a notarized rescission with the Department of Public Health or a petition in the Probate and Family Court, the acknowledgment establishes parentage with the same effect as a court judgment. After that it can be challenged only within one year and only for fraud, duress or material mistake of fact. If a signer is a party to a court or administrative proceeding about the child within the 60 days and does not rescind then, the acknowledgment becomes final at that point.

A petition to change a name is heard by the probate court in the county where the petitioner lives, and the change must be granted unless it is inconsistent with the public interest. The court requests a report from the commissioner of probation and requires a copy of the birth record (and records of any earlier name change). Under the version of the law effective November 25, 2025, public notice (publication) is required only if the court orders it for good cause, and name change records are not open to public inspection unless the court orders otherwise or the petitioner requests it.
