Common Law Marriage in Massachusetts

Many couples believe that couples living together for a long time create a “common law marriage.” This is a common assumption, especially for couples who share a home, finances, or children.
Massachusetts law does not recognize common law marriage. Many family law cases involve this issue because unmarried couples often expect the same legal rights as married spouses.
This article explains common law marriage, whether it exists in Massachusetts, and what legal rights apply to unmarried couples.

What Is Common Law Marriage?

Common law marriage is a legal concept recognized in some states. Some states recognize marriages formed without a formal ceremony or marriage license if legal requirements are satisfied.
While the rules vary by state, common law marriage typically requires:

• Living together for an extended period
• Intending to be married
• Holding yourselves out to others as a married couple

When recognized, common law marriage creates the same legal rights and responsibilities as a traditional marriage.

Does Massachusetts Recognize Common Law Marriage?

Massachusetts requires couples to enter a marriage lawfully through a license and formal ceremony before the state recognizes the relationship.
This means that:

• Massachusetts law does not create an automatic marriage after a certain number of years.
• Living together does not create spousal rights.
• Referring to each other as “husband” or “wife” does not make the relationship legally binding.

This has been settled by Massachusetts law for many years and is consistently confirmed by state statutes and court decisions.

Why Many Couples Believe They Are Common Law Married

Despite the law, many people still believe common law marriage exists in Massachusetts. This confusion often comes from:

• Extended shared living arrangements
• Sharing children
• Joint bank accounts or property
• Filing joint tax returns as a couple
• Social or cultural beliefs about marriage

These factors may reflect a committed relationship, but they do not create a legal marriage under Massachusetts law.

Legal Rights of Unmarried Couples in Massachusetts

Unmarried couples have fewer legal rights than married spouses, but some protections may still apply under Massachusetts family law.

Property and Finances

In some situations, unmarried partners use a cohabitation agreement to clarify property rights and financial responsibilities.
Property rights depend on:

• Title ownership
• Written agreements
• Contract and equity principles

The law does not provide an automatic right to divide property the way it does in a divorce.

Children and Parenting

Unmarried parents still have legal rights and responsibilities regarding their children, including matters involving child custody and parenting time.

• Child custody
• Parenting time
• Child support

These decisions are based on the best interests of the child, not the parents’ marital status.

Support Between Partners

Unmarried partners generally do not have the right to spousal support (alimony), even after a long-term relationship.

What Happens When an Unmarried Couple Separates?

Because there is no marriage, there is also no divorce process for unmarried couples.
Instead:

• Property disputes may be handled through civil court
• Parenting issues are addressed separately in family court
• Financial protections are limited compared to divorce

This can come as a surprise to couples who assumed their relationship would be treated like a marriage.

Common Law Marriages From Other States

Massachusetts may recognize a valid common law marriage from another state, as long as:

• The couple formed the common law marriage in a state where it is legal
• The relationship met that state’s legal requirements

If recognized, the marriage is treated as valid in Massachusetts, including for divorce or inheritance purposes.

When to Speak With a Family Law Attorney

It may be helpful to speak with a family law attorney if you:

• Are in a long-term cohabiting relationship
• Own property together
• Share children
• Are separating from an unmarried partner
• Want to protect your legal and financial interests

Understanding your rights early with informed legal advice can help prevent costly disputes later.
