Marriage laws in the United States vary by state, and one of the more misunderstood issues is cousin marriage. In Massachusetts—from Boston to Springfield and from Cape Cod to the Berkshires—residents often wonder whether it’s legal to marry a cousin. The question carries both cultural and legal weight.
This article offers a detailed look at Massachusetts law regarding cousin marriage. It covers legal statutes, regional perspectives, health considerations, and evolving public attitudes to help residents and out-of-state couples understand their rights.
Understanding Marriage Laws in Massachusetts
Marriage in Massachusetts is governed by state statutes that set out rules on eligibility, prohibited relationships, age requirements, and licensing procedures. These laws aim to ensure that marriages are entered into voluntarily and legally.
Key Legal Requirements
- Age: Individuals must be 18 or older, or at least 16 with court approval.
- Consent: Both parties must be mentally competent to consent.
- Relation: Marriages are prohibited between certain close relatives.
It’s the third factor—relation—that is most relevant when it comes to marrying a cousin.
The Massachusetts Law on Cousin Marriage
What the Law Says
Massachusetts prohibits marriage between immediate family members, such as parent-child, siblings, and aunts/uncles with nieces/nephews. However, first cousin marriage is not prohibited under state law.
Prohibited Relationships
Massachusetts law forbids marriage between the following:
- Parent and child
- Grandparent and grandchild
- Siblings (including half-siblings)
- Aunt or uncle with their niece or nephew
First cousins are not included on this list, which means such marriages are legally recognized.

Regional Perspectives in Massachusetts
Greater Boston
Diverse and multicultural, cities like Boston, Cambridge, and Somerville may be more accepting of cousin marriage due to cultural familiarity in immigrant communities.
Western Massachusetts
In areas like Springfield and Pittsfield, cousin marriages are legal but may be less common or more culturally stigmatized in traditional New England communities.
Cape Cod and the Islands
Regions like Nantucket and Martha’s Vineyard follow the same marriage laws. Local municipalities provide marriage licenses without discriminating against cousin couples.
Why Massachusetts Permits Cousin Marriage
Historical Reasons
Unlike some states that outlawed cousin marriage in the 19th century due to eugenics concerns, Massachusetts never adopted such a ban. This may reflect its progressive legal history and more urban, immigrant-rich population.
Scientific Research
Modern genetics show only a moderate increase in risk for children of first cousins—about 4–7%, compared to 3–4% in unrelated couples. The risk is comparable to that of older maternal age and is not considered prohibitive by most medical professionals.
Cultural Considerations
Massachusetts’ diversity means many communities—including South Asian, Middle Eastern, and African populations—consider cousin marriage a normal and accepted practice.
How to Get Married as Cousins in Massachusetts
License Requirements
- Apply at any city or town clerk’s office.
- No residency requirement.
- Must wait three days after applying (waivers available).

No Extra Requirements for Cousins
Cousin couples are not subject to additional forms, screenings, or medical tests. Clerks may not deny a marriage license based on the familial relationship if it’s legal.
Public Attitudes Toward Cousin Marriage
In Cities
Urban centers like Boston and Worcester are more likely to be tolerant due to cultural diversity.
In Smaller Towns

Health and Genetics Considerations

Medical Community View

Cousin marriage is:
- Legal and more common in Canada, the UK, and many European and Middle Eastern nations.

Massachusetts’ legal stance aligns more closely with international norms than some U.S. states.
