The law in plain words
Under G.L. c. 208, § 31, parents' rights are "held to be equal" unless one has committed misconduct. "The happiness and welfare of the children shall determine their custody."
Wondering who usually ends up with custody? Our page on the chances of getting full custody in Massachusetts explains what the figures can and cannot show.
Legal custody and physical custody
Massachusetts has four custody types.
- Sole legal custody: one parent makes the major decisions, like school, medical care and religious upbringing.
- Shared legal custody: both parents make those decisions together.
- Sole physical custody: the child lives with one parent. The other gets reasonable parenting time, unless that would not be in the child's best interest.
- Shared physical custody: the child lives with each parent for periods of time, with frequent and continued contact with both.
The statute still says "visitation." The court now calls it parenting time.
A parent without custody can still see the child's school and medical records.
Is Massachusetts a 50/50 state?
No. At trial, § 31 says there is no presumption either for or against shared legal or physical custody. The only exception is the abuse presumption below.
The state's highest court has rejected the claim that the law favors joint physical custody. Even "shared physical custody" means frequent contact, not an equal split.
- While a divorce is pending: married parents have temporary shared legal custody, unless there is an emergency, abuse or neglect. A judge can order temporary sole legal custody with written findings.
- No temporary shared physical custody: the law creates no presumption of it.
- At trial: a parent asking for shared custody in a contested case must file a shared custody implementation plan.
Shared-parenting bills were sent to study in 2025 and 2026. None became law.
What the judge considers
Chapter 208 has no numbered list of factors. The court's own guidance lists what judges look at:
- the child's well-being, school and community
- the child's relationships with each parent and others
- any abuse, drug use or abandonment
- whether one parent has been the primary caregiver
- the child's preference, depending on age and maturity
The judge must also ask whether the child's living conditions hurt the child's physical, mental, moral or emotional health.
For unmarried parents, c. 209C, § 10 adds more. The judge must try to preserve the child's bond with the primary caretaker. The judge also looks at where the child lived in the last six months.
Those points do not create a presumption for the current caretaker. A judge must weigh all relevant factors.
Your child's preference
No Massachusetts law sets an age at which a child decides. The child's preference is one factor, and it does not control the outcome on its own.
In a custody case between unmarried parents under Chapter 209C, a child 14 or older must be added to the case as a party. The child takes part formally, but does not get the final say.
In one appeal, a 10-year-old's preference was not given decisive weight. Young children's views generally carry little weight.
The judge may appoint a guardian ad litem to investigate and write a report. The report is kept from the public. A parent without a lawyer must file a motion to get a copy.
Mothers' and fathers' rights
For married parents, neither starts ahead. Section 31 holds parents' rights equal, unless one has committed misconduct.
For unmarried parents, the rule is different. The parent who gave birth has custody until a court orders otherwise. See the next section.
A father's chances depend on the same evidence as anyone's: his role, his home and the child's needs.
If you were never married
Since January 1, 2025, Chapter 209C says the person who gave birth has custody before parentage is established. That parent keeps custody afterward until a court orders otherwise.
Signing an acknowledgment of parentage does not, by itself, give the other parent custody rights.
- The acknowledgment: signed and notarized by both parents. Once final, it has the force of a court judgment.
- Changing your mind: either signer can cancel within 60 days. Since July 1, 2025, a notarized cancellation can be filed with the Department of Public Health.
- An earlier cut-off: a signer may become a party to a court or agency case about the child within the 60 days. If so, they must cancel then.
- After that: a challenge is allowed within one year, only for fraud, threats or pressure, or a serious mistake about the facts.
Joint custody has a stricter test for unmarried parents. It needs a court-approved agreement, or proof the parents already shared responsibility and can plan together.
To ask for custody, establish parentage first. Use the Complaint to Establish Parentage (CJD 106), or CJD 109 if parentage is already established.
Domestic violence and abuse
Under c. 208, § 31A, the judge must weigh past or present abuse against the abusive parent.
A pattern of abuse, or one serious incident, creates a presumption, a starting assumption the abusive parent can try to disprove. Sole or shared custody with the abusive parent is presumed not in the child's best interests.
- Abuse here means: causing or trying to cause bodily injury, or causing reasonable fear of it. A serious incident includes forced sex.
- Rebutting it: the abusive parent must show the custody award is in the child's best interests.
- A 209A order alone does not prove a pattern, but the facts behind it can.
- Findings: the judge must write findings on the abuse's effect on the child within 90 days.
- Safeguards: the judge can order supervised visits or exchanges, a batterer's program, or no overnights.
Since September 18, 2024, abuse under the 209A restraining order law includes coercive control. Section 31A has its own definition of abuse, which was not changed. It does not mention coercive control, so whether that alone triggers the presumption is not settled.
A 209A abuse prevention order can award temporary custody. It can be granted without notice if there is immediate danger. A hearing follows within 10 court business days. Filing is free.
Emergency and temporary orders
- Temporary orders: file a Motion for Temporary Orders (CJD 400) with an affidavit. The court sets a hearing, and the order lasts until replaced.
- While a divorce judgment is being modified: a custody order without notice is allowed only in an emergency. It lasts no more than five days, and the other parent gets notice and a hearing date.
- Abuse: a 209A abuse prevention order can include temporary custody. If a Probate Court custody order already exists, custody in a 209A order from another court lasts no more than 30 days.
Massachusetts courts can also act in an emergency to protect a child who is in the state.
Moving with your child
Under c. 208, § 30, a child of divorced parents born in Massachusetts, or living there five years, cannot be moved out of state without consent. A child old enough must consent; for a younger child, both parents must.
Without consent, the move needs a court order "upon cause shown." That phrase means the move must be in the child's best interests. The test depends on how parenting is split.
- Sole physical custody: the first question is whether the moving parent has a good, sincere reason, called a "real advantage." Then the judge weighs all the effects on the child.
- Shared physical custody: the child's best interests decide. The moving parent's own advantage counts for much less.
Courts apply the same tests to unmarried parents. Before any parentage or custody order exists, the consent rule above may not apply. A case already in court, a restraining order, or rules on which state hears the case can still stop a move.
No statute covers moves within Massachusetts. A move that breaks the schedule can lead to a modification case.
Changing custody
- After divorce: under § 28, the parent asking must show a material and substantial change in circumstances. The change in custody must also be needed for the child's best interests.
- Unmarried parents: under c. 209C, § 20, a substantial change in the parents' or the child's circumstances is needed.
- Agreement: if both parents agree, they can file a joint agreement for the judge to approve.
File a Complaint for Modification (CJD 104). When a divorce judgment is being modified, temporary orders need specific findings of the harm expected without them.
The parenting course
Under Standing Order 3-23, parents must take "Two Families Now" in new divorce, separate support, parentage and custody cases. Joint petitions for an agreed divorce are excluded. In a modification or contempt case, a judge may order it.
- Format: a four-hour online course, taken at your own pace.
- Cost: $49 per parent. It can be waived for parents who cannot afford it.
- Deadlines: register within 30 days of service, and finish within 30 days of registering.
- Proof: file the certificate within 14 days of finishing.
A parent can ask to skip it, for example where communication with the other parent is unsafe. Missing it can lead to sanctions.
How to file for custody in Massachusetts
Massachusetts must usually be the child's home state, meaning the child lived there for the six months before filing. Massachusetts still uses its own jurisdiction law, Chapter 209B, rather than the uniform act most states use.
- Choose the case type. Married parents ask for custody in the divorce. Unmarried parents file a parentage or custody complaint.
- Pick the county. Outside divorce, file where the child lives.
- Fill in the Child Care or Custody Disclosure Affidavit. This is the form people call the "affidavit of care and custody." It lists the child's addresses for the last two years.
- File in the Probate and Family Court, in person, by mail or through eFileMA.
- Serve the other parent, with the parenting course notice.
Addresses can be kept confidential if safety is at risk. The court's filing guide lists every form.
How much does it cost to file for custody in Massachusetts?
Fees come from the Probate and Family Court fee list.
| Filing | Fee |
|---|---|
| Divorce complaint | $215 |
| Custody, parenting time or parentage complaint | $115 |
| Each summons | $5 |
| Complaint to modify custody or parenting time | $50 |
| Complaint to move a child out of state, after judgment | $50 |

You qualify for a waiver if you get certain benefits, or your after-tax income is at or below 125% of the poverty line. You also qualify if paying would mean going without basic needs. File an Affidavit of Indigency with your complaint. If it is complete and shows you qualify, the clerk must waive normal fees without a hearing.
What changed recently
- November 5, 2025: allowing gender-affirming care that another state bans cannot, by itself, be used to change custody.
- July 1, 2025: an acknowledgment of parentage can be canceled by filing with the Department of Public Health.
- January 1, 2025: the Parentage Act rewrote Chapter 209C in gender-neutral terms.

Building the record
Massachusetts judges look at who has been the primary caregiver, and where the child has lived. Those questions are answered with dates, not adjectives.
Note each exchange, school task and doctor visit as it happens. Casewell keeps those notes and the messages behind them together, so a lawyer can read a clear timeline.
Before you record a call or a handover, check whether you can record your co-parent in Massachusetts.
