Legal Separation and Annulment in Massachusetts

Whether Massachusetts offers legal separation, how it differs from divorce, and the grounds for an annulment.

Short answer: 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. Mass. Gen. Laws ch. 209, § 32

Legal separationMassachusetts 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.
AnnulmentIf 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.
