How is child custody decided in Massachusetts?

Federal & State Law Editorial TeamLast reviewed: 2026-04-30

Massachusetts child custody is governed by G.L. c. 208, § 31 (divorce) and G.L. c. 209C, § 10 (children of unmarried parents).

1. Forms of Custody (G.L. c. 208, § 31)

  • Sole legal custody — one parent has the right and responsibility to make major decisions including education, medical care, emotional, moral, and religious development.
  • Shared legal custody — both parents share these rights and responsibilities.
  • Sole physical custody — child resides with and is under the supervision of one parent, subject to reasonable visitation by the other parent.
  • Shared physical custody — child has periods of residing with and being under the supervision of each parent.
  • 2. Temporary Orders and Presumption (G.L. c. 208, § 31)

    For temporary orders pending divorce, in the absence of evidence to the contrary, there is a presumption that temporary shared legal custody is in the best interest of the child. There is no presumption as to physical custody at the temporary stage, and no presumption for permanent shared legal custody.

    3. Abuse Prohibition (G.L. c. 208, § 31A)

    A finding by a preponderance of the evidence of a pattern or serious incident of abuse creates a rebuttable presumption that it is not in the child's best interest to be placed in sole or shared legal or physical custody with the abusive parent. Written findings are required.

    4. Best Interest Factors

    Massachusetts does not have a single statutory list, but case law (notably Custody of Kali, 439 Mass. 834 (2003)) directs courts to consider:

  • The child's relationship with each parent.
  • Each parent's ability to provide a stable, loving, supportive environment.
  • Each parent's mental and physical health.
  • Each parent's history of abuse.
  • The child's adjustment to home, school, and community.
  • The child's preferences if of sufficient age.
  • The willingness of each parent to facilitate the child's relationship with the other parent.
  • The desirability of preserving sibling relationships.
  • 5. Child's Preference

    No statutory age. Massachusetts courts consider the wishes of children with sufficient maturity. The court may interview the child in chambers, often in the presence of the Guardian ad Litem if appointed.

    6. Guardian ad Litem

    Massachusetts probate and family courts frequently appoint a GAL to investigate and report on custody (M.G.L. c. 215, § 56A). Reports are influential.

    7. Modification (G.L. c. 208, § 28)

    Requires a material and substantial change in circumstances since the prior judgment, plus a finding that modification is in the child's best interest (Yannas v. Frondistou-Yannas, 395 Mass. 704 (1985)).

    8. Removal from Massachusetts (G.L. c. 208, § 30)

    A child of divorced parents shall not be removed out of the Commonwealth without consent of both parents or court order. The court applies:

  • For sole custody: the Yannas v. Frondistou-Yannas test — does the move have a 'real advantage' to the custodial parent, and is it in the child's best interest?
  • For shared custody: the Mason v. Coleman, 447 Mass. 177 (2006) test — pure best interest analysis without a presumption favoring the moving parent.
  • This is legal information, not legal advice.
