Is Polyamory Legal in Somerville, Massachusetts?
Polyamory itself is not a crime in Massachusetts. Adults can engage in multiple consensual relationships without facing state criminal charges. Somerville follows state law, so local police do not enforce anti-polyamory statutes.
Marriage, Civil Unions, and Polyamorous Families
Massachusetts only issues marriage licenses to two people. Polyamorous households cannot obtain a single marriage license for three or more partners. Some families use contracts, co-parenting agreements, and estate planning to clarify rights. Courts generally enforce contracts that are clear, consensual, and do not violate public policy.
Local Enforcement, Housing, and Benefits
Somerville enforces state family law and local housing rules. Landlords may set their own occupancy standards, but they cannot discriminate based on relationship structure if it conflicts with fair housing law. For issues involving taxes, insurance, or parental rights, consult a licensed attorney. You can review general Massachusetts family law guidance at mass.gov.
