Common Law Marriage in Connecticut: Is It Recognized? (2026)

Connecticut does not recognize common law marriage and never has. Connecticut courts have consistently held that a valid marriage requires a license and ceremony. However, Connecticut does recognize a common-law marriage validly formed in another state under the principle of comity and the Full Faith and Credit Clause.

Does Connecticut Recognize Common Law Marriage?

No. Connecticut does not permit couples to form a common-law marriage. Connecticut has never recognized common-law marriage under its own law, making it one of the states that maintained a license-and-ceremony requirement from the beginning of its statehood rather than abolishing a previously recognized practice.

Connecticut General Statutes section 46b-22 establishes the authority of officials to solemnize marriages in Connecticut, and section 46b-25 requires a marriage license before a marriage ceremony may be performed. There is no provision in Connecticut law for a marriage to arise from cohabitation, mutual agreement, or the passage of time. No amount of living together, using the same last name, filing joint tax returns, or calling each other spouses creates a valid Connecticut marriage without a license and ceremony.

The Connecticut Supreme Court addressed this directly in McAnerney v. McAnerney, 165 Conn. 277 (1973), affirming that Connecticut does not recognize common-law marriages formed within its borders. Connecticut courts have consistently applied this rule in the decades since, declining to extend marriage status to couples who did not comply with the statutory requirements regardless of the length or nature of their relationship.

Connecticut Has Never Recognized Common Law Marriage

Unlike states such as Alabama (which abolished common-law marriage effective January 1, 2017) or Pennsylvania (which abolished it effective January 1, 2005), Connecticut did not abolish a previously recognized form of marriage. Connecticut never recognized common-law marriage formation as a matter of its own law.

This historical posture means there is no grandfather date, no cutoff, and no class of pre-existing common-law marriages formed within Connecticut that retain validity. Any couple who believes their cohabiting relationship in Connecticut constitutes a marriage under Connecticut law is mistaken, regardless of when the relationship began.

The Legislature has never acted to introduce common-law marriage, and no such legislation has been seriously considered in recent sessions. The Connecticut Family Law Act (C.G.S. Title 46b) addresses marriage, dissolution, and family relations comprehensively without providing any common-law marriage pathway.

Out-of-State Common Law Marriages: Connecticut Recognizes Them

Although Connecticut does not allow common-law marriages to form here, Connecticut courts recognize a common-law marriage validly formed in another state under the doctrine of comity and the Full Faith and Credit Clause of the United States Constitution (Art. IV, sec. 1). This means that a couple who formed a valid common-law marriage in Colorado, Texas, Iowa, Kansas, Montana, Rhode Island, the District of Columbia, or another jurisdiction that permits common-law marriage will be treated as legally married in Connecticut when they relocate or interact with Connecticut courts.

Connecticut courts apply the law of the state where the marriage was formed to determine whether the couple met the requirements for a valid common-law marriage in that state. The requirements vary by state but generally include: legal capacity to marry (both parties unmarried and of sufficient age), a present mutual agreement to be married rather than merely to live together, cohabitation in the state where the marriage is claimed, and publicly holding out as a married couple in that state. A couple must satisfy the standards of the originating state, not Connecticut standards, for the marriage to be recognized.

Once recognized in Connecticut, the common-law marriage carries the same legal consequences as a ceremonial marriage: equitable distribution of marital property, spousal support eligibility, inheritance rights, and the right to seek dissolution through the Connecticut courts.

How to Prove a Common Law Marriage in Connecticut

Because Connecticut does not form common-law marriages, proof of common-law marriage arises only when a party claims that a valid common-law marriage was formed in another state before the couple came to Connecticut. In those proceedings, Connecticut courts apply the law of the state where the marriage allegedly formed and evaluate whether the evidence meets that state's requirements.

Documentary evidence that courts typically consider includes:

• Joint federal and state tax returns filed as married
• Mortgage documents, deeds, or bank accounts listing both persons as spouses
• Insurance policies or retirement account beneficiary designations naming the other person as "spouse"
• Affidavits from family members, coworkers, or neighbors confirming the couple held themselves out as married in the originating state
• Records showing the couple used the same surname or introduced each other as husband and wife
• Medical records, hospital admission forms, or emergency contact designations listing the other person as spouse

No single document is conclusive. Courts evaluate the full record to determine whether the couple genuinely agreed to be married and publicly represented themselves as married under the law of the state where the relationship was based. A couple who lived informally in Connecticut without ever claiming a common-law marriage in another state cannot retroactively invoke the doctrine.

How a Common Law Marriage Ends in Connecticut

A common-law marriage validly formed in another state and recognized in Connecticut can only be dissolved by formal divorce through the Connecticut Superior Court. There is no common-law divorce. The couple remains legally married until a court enters a dissolution judgment, and all standard Connecticut dissolution procedures under C.G.S. Title 46b apply.

This requirement has real consequences. A common-law spouse who simply walks away from the relationship remains legally married. If that person later enters a ceremonial marriage in Connecticut or elsewhere without first obtaining a divorce, that second marriage is void. The former common-law spouse retains equitable distribution rights in marital property acquired during the marriage, spousal support rights, and intestate inheritance rights.

Spouses in a recognized common-law marriage who separate in Connecticut must go through a full dissolution proceeding to divide property, address support, and resolve any parenting issues, just as any other married couple would.

The 7-year myth. A widespread misconception holds that cohabiting for seven years automatically creates a common-law marriage. This is false everywhere in the United States. No state has ever required a specific number of years of living together as the trigger for common-law marriage. In Connecticut, no amount of cohabitation creates a marriage. In states that do recognize common-law marriage, the requirements focus on mutual present agreement to be married and public holding-out as spouses, not on any durational threshold.

Cohabiting Couples in Connecticut: Rights and Protections

Connecticut law does not provide a general domestic partnership or civil union status for opposite-sex couples who are not married (same-sex civil unions were converted to marriages by Connecticut following the passage of marriage equality). Couples who choose to cohabit without marrying in Connecticut generally do not acquire marital property rights through cohabitation alone.

However, unmarried cohabiting partners in Connecticut may have contractual or equitable claims against each other when a relationship ends, depending on their specific arrangements. Courts may enforce express agreements about property, finances, or support between cohabiting partners. The availability of such claims depends on the facts of the individual relationship and does not rest on any common-law marriage theory.

Unmarried cohabiting partners should consult a Connecticut family law attorney about cohabitation agreements, beneficiary designations, powers of attorney, and joint ownership arrangements to protect their interests, since Connecticut marital-status protections do not apply to them automatically.
