Connecticut does not recognize common law marriage under any circumstances, regardless of how long a couple has lived together or whether they hold themselves out as married. Under Connecticut General Statutes § 46b-28a, couples cannot establish marital rights through cohabitation alone. However, Connecticut will recognize valid common law marriages formed in other states under the Full Faith and Credit Clause of the U.S. Constitution. If you established a common law marriage in one of the seven states that still permit them (Colorado, Iowa, Kansas, Montana, New Hampshire, Texas, or Utah), you must obtain a formal divorce in Connecticut to legally end that relationship. The filing fee for divorce in Connecticut is $360 as of March 2026, with a 90-day waiting period from the return date under C.G.S. § 46b-67 for contested cases.

Does Connecticut Recognize Common Law Marriage?
Connecticut does not recognize common law marriage for couples who live together within state borders. Under Connecticut General Statutes §§ 46b-11 and 46b-12, only couples who obtain a civil marriage license and complete a formal ceremony are considered legally married. No amount of cohabitation, joint property ownership, shared children, or public declarations of marriage will create a legal marriage in Connecticut. The Connecticut Supreme Court has consistently upheld this position since at least 1973, and the 2026 legislative session did not change this fundamental rule.
This means unmarried couples in Connecticut lack critical legal protections. Without formal marriage, partners cannot claim spousal inheritance without a will, automatic survivor benefits under Social Security, rights to file joint tax returns, automatic hospital visitation rights, or standing to sue for wrongful death. Partners who separate after long-term cohabitation have no automatic right to property division or alimony. Connecticut courts will not treat the relationship dissolution like a divorce, regardless of how closely the arrangement resembled a traditional marriage.
How Connecticut Treats Out-of-State Common Law Marriages
Connecticut courts will recognize a valid common law marriage established in another state that permits such unions, provided the marriage does not violate Connecticut public policy such as marriages involving minors or prohibited familial relationships. The Full Faith and Credit Clause of the U.S. Constitution requires Connecticut to honor legal marriages from other jurisdictions. As of 2026, seven states plus the District of Columbia still allow new common law marriages to be formed: Colorado, Iowa, Kansas, Montana, New Hampshire (for inheritance purposes only), Texas, and Utah.
If you and your partner established a common law marriage in one of these states and now live in Connecticut, you are legally married under Connecticut law. This recognition carries significant consequences. You must obtain a formal divorce to end the relationship. You cannot simply separate and move on as unmarried individuals. Connecticut courts have full authority to divide property, award alimony, and establish custody and support arrangements for children born during the common law marriage. The divorce process follows identical procedures whether the underlying marriage was ceremonial or common law.
Requirements to Prove a Valid Common Law Marriage
To dissolve a common law marriage in Connecticut, you must first prove that a valid common law marriage exists under the law of the state where it was formed. Requirements vary by state but generally include mutual present agreement to be married (both partners must consent to being spouses now, not in the future), cohabitation as a married couple, and public representation of the marriage to family, friends, employers, and the community. The burden of proof falls on the party asserting the marriage existed.
Connecticut courts examine evidence from the originating state to determine validity. Relevant proof includes joint bank accounts listing both parties as spouses, joint tax returns filed as married, insurance policies naming the partner as spouse, testimony from friends and family about the couples presentation as married, joint ownership of property as husband and wife, and any written agreements acknowledging the marital relationship. Courts in Connecticut apply the substantive law of the state where the common law marriage was allegedly formed, meaning a marriage valid in Colorado but formed before moving to Connecticut remains valid even if Connecticut itself would not have recognized such a marriage formed locally.
Filing for Divorce from a Common Law Marriage in Connecticut
The process for divorcing a common law spouse in Connecticut mirrors the standard divorce procedure. Connecticut requires at least one spouse to have been a Connecticut resident for a minimum of 12 months before the court can grant a final dissolution decree under C.G.S. § 46b-44. You may file the divorce complaint before the 12-month period completes, but the court will not issue a final judgment until residency requirements are satisfied. Military members who were Connecticut residents before joining the service maintain Connecticut residency for divorce purposes throughout their service.
The filing fee for divorce in Connecticut is $360 as of March 2026, plus approximately $50 for service of process, bringing minimum court costs to $410. Additional costs may include parenting education programs ($150 per party, or $300 total) if minor children are involved. Filing fee waivers are available through Form JD-FM-75 for individuals whose income falls below 125% of the federal poverty level or who receive state assistance such as SNAP, TFA/TANF, or Medicaid. Waivable fees include the entry fee, filing fee, service of process costs, and parenting education program costs.
Grounds for Divorce in Connecticut
Connecticut permits both no-fault and fault-based divorce under C.G.S. § 46b-40. The overwhelming majority of divorces, including those dissolving common law marriages, proceed on no-fault grounds. The primary no-fault ground is irretrievable breakdown of the marriage, which requires no proof of wrongdoing by either spouse. Either spouses testimony that the marriage has irretrievably broken down with no reasonable prospect of reconciliation is sufficient for the court to grant the divorce.
An alternative no-fault ground exists when spouses have lived apart due to incompatibility for a continuous period of at least 18 months immediately before service of the complaint, with no reasonable prospect of reconciliation. Fault-based grounds include adultery, fraudulent contract, willful desertion for one year, seven years absence, habitual intemperance, intolerable cruelty, imprisonment for life or conviction of an infamous crime, and confinement for psychiatric disability for five or more years. While fault is not a statutory factor for property division under C.G.S. § 46b-81, it can influence alimony awards under C.G.S. § 46b-82.
Property Division in Common Law Divorce Cases
Connecticut is an all-property equitable distribution state under C.G.S. § 46b-81, meaning courts can divide any asset owned by either spouse regardless of when or how it was acquired. This includes property acquired before the marriage, inheritances received by one spouse alone, and gifts from third parties. Connecticut makes no distinction between separate and marital property, which contrasts sharply with neighboring states where premarital property is typically protected from division. The typical property division in Connecticut ranges from 40/60 to 60/40 depending on multiple statutory factors.
Courts consider 12 statutory factors when dividing property: the length of the marriage, the causes for the dissolution, the age and health of each party, their respective occupations and stations in life, amount and sources of income, vocational skills and employability, the estate of each party, their liabilities and needs, the opportunity of each to acquire future assets and income, and each partys contribution toward the acquisition, preservation, or appreciation of assets. The landmark Connecticut Supreme Court decision in Bender v. Bender (258 Conn. 733, 2001) established that property includes any interest, whether vested or unvested, including pension benefits subject to equitable distribution.
Timeline and Waiting Periods for Divorce
Connecticut divorce cases proceed through several stages with mandatory timing requirements. After filing the complaint, the court assigns a return date, which starts the waiting period clock. Under C.G.S. § 46b-67, contested divorces traditionally required a 90-day waiting period from the return date before the court could enter a dissolution decree. However, Public Act 23-46 substantially revised this provision, and couples who reach a full agreement on all issues may now obtain a final judgment significantly faster, potentially as early as the return date itself.
For couples seeking the fastest resolution, Connecticuts nonadversarial divorce process under C.G.S. § 46b-44a allows divorces within approximately 35 days without a court appearance. However, strict eligibility criteria apply: the marriage must have lasted 9 years or fewer, no children were born to or adopted by the couple, neither spouse is pregnant, neither owns real property, combined assets total less than $80,000, neither has a defined benefit pension, no bankruptcy is pending, and no restraining orders exist between the parties. Most common law marriages would not qualify for this expedited process due to typical marriage duration or asset accumulation.
Property Rights for Unmarried Couples Who Are Not Common Law Married
If you cohabited in Connecticut without establishing a common law marriage in another state, you have no automatic property rights upon separation. Connecticut courts will not divide property or award support between unmarried partners using divorce law principles. Living together, regardless of duration, does not entitle either party to rights in the other partys property. There is no palimony in Connecticut, and long-term cohabitation does not create quasi-marital rights.
However, Connecticut courts will enforce valid cohabitation agreements between unmarried partners. In 1987, the Connecticut Supreme Court ruled that cohabitation agreements are express contracts enforceable according to ordinary contract principles. These agreements can establish rights regarding financial support similar to alimony, distribution of property accumulated during the relationship, and ownership of jointly acquired assets. Courts will not enforce agreements explicitly founded on sexual services, but will enforce agreements addressing financial and property matters. Without a written agreement, couples face costly and protracted litigation over property and financial matters, requiring proof of implied contracts, partnership agreements, joint ventures, or other tacit understandings.
Cohabitation Agreements as an Alternative to Marriage
For couples who choose not to marry but want legal protection, Connecticut recognizes cohabitation agreements as valid contracts. These agreements allow unmarried partners to establish rights and obligations arising from their relationship while remaining unmarried. Typical provisions address how property will be divided if the relationship ends, whether one partner will pay support to the other after separation, ownership of real estate, vehicles, and other assets, responsibility for debts incurred during the relationship, and inheritance rights between partners.
Cohabitation agreements must be in writing to be reliably enforceable. While Connecticut courts have recognized oral agreements, proving their terms becomes extraordinarily difficult without written documentation. Unlike divorce proceedings, disputes over cohabitation agreements proceed through general civil litigation rather than family court, applying contract law principles rather than divorce statutes. This often results in longer timelines and higher costs. Partners should consult with an attorney when drafting cohabitation agreements to ensure enforceability and comprehensive coverage of potential issues.
Comparison: Married Couples vs. Unmarried Cohabitants in Connecticut
| Issue | Married Couples | Unmarried Cohabitants |
|---|---|---|
| Property Division | Court divides all property equitably under C.G.S. § 46b-81 | No automatic division; contract law applies |
| Spousal Support/Alimony | Available under C.G.S. § 46b-82 | Not available unless cohabitation agreement exists |
| Inheritance Rights | Statutory share if spouse dies without will | No automatic inheritance; requires will |
| Social Security Benefits | Eligible for spousal and survivor benefits | Not eligible for partners benefits |
| Health Insurance | Can cover spouse on employer plans | May not qualify as domestic partner |
| Medical Decisions | Default authority for incapacitated spouse | Requires healthcare proxy document |
| Tax Filing | Can file jointly | Must file separately |
| Hospital Visitation | Automatic spousal rights | May be restricted without documentation |
Steps to Protect Yourself If You Believe You Have a Common Law Marriage
If you lived with a partner in a state that recognizes common law marriage and believe you may be common law married, take immediate steps to clarify your legal status. First, gather evidence of the marriage from the state where it was allegedly formed, including joint tax returns, joint bank accounts, insurance documents, and written communications referring to each other as spouses. Second, consult with a Connecticut family law attorney who can evaluate whether your relationship meets the requirements for common law marriage recognition.
If you are common law married and wish to separate, you must file for divorce in Connecticut rather than simply ending the cohabitation. Failure to obtain a divorce leaves you legally married, which affects your ability to remarry, your tax filing status, your rights to the other persons estate, and potential liability for debts incurred by your spouse. If you are not common law married but have accumulated joint property or want financial protection upon separation, consider drafting a separation agreement or pursuing civil litigation based on contract or equity principles to protect your interests.
Frequently Asked Questions About Common Law Divorce in Connecticut
Can I establish a common law marriage by living together in Connecticut?
No, Connecticut does not permit couples to establish common law marriages within its borders under any circumstances. Under C.G.S. §§ 46b-11 and 46b-12, marriage in Connecticut requires a civil marriage license and formal ceremony. Cohabitation for 5, 10, 20, or more years does not create marital rights. Joint property ownership, shared children, and holding yourselves out as married also do not establish common law marriage in Connecticut.
How do I divorce my common law spouse in Connecticut?
You file for divorce using the same procedures as any other divorce. One spouse must have been a Connecticut resident for at least 12 months under C.G.S. § 46b-44. File Form JD-FM-3 (Divorce Complaint) at the Superior Court, pay the $360 filing fee, and serve your spouse. You must prove the common law marriage was valid under the law of the state where it was formed.
What states still recognize common law marriage in 2026?
Seven states plus Washington D.C. currently allow new common law marriages: Colorado, Iowa, Kansas, Montana, New Hampshire (inheritance purposes only), Texas, and Utah. Several other states (Alabama, Florida, Georgia, Indiana, Ohio, Pennsylvania, South Carolina) recognize common law marriages formed before specific cutoff dates when those states abolished the practice.
Will Connecticut recognize my common law marriage from another state?
Yes, under the Full Faith and Credit Clause and C.G.S. § 46b-28a, Connecticut recognizes valid common law marriages established in states that permit them, provided the marriage does not violate Connecticut public policy. You would be treated as legally married for all purposes including divorce, property division, and spousal support.
How much does it cost to divorce a common law spouse in Connecticut?
Minimum court costs total approximately $410 ($360 filing fee plus $50 service of process) as of March 2026. If you have minor children, add $300 for mandatory parenting education programs. Attorney fees range from $250 to $600 per hour in Connecticut. An uncontested divorce with attorney assistance typically costs $1,500 to $5,000, while contested divorces average $15,000 to $30,000.
What happens to property if we separate but were never legally married?
Without a valid marriage or written cohabitation agreement, Connecticut courts will not divide property using divorce law principles. Property goes to whoever holds legal title. Joint accounts are typically split according to contributions or ownership designations. Disputes require civil litigation under contract law, which often proves more expensive and unpredictable than divorce proceedings.
Can I get alimony after ending a long-term unmarried relationship?
No, Connecticut does not award palimony or support to unmarried partners absent a valid cohabitation agreement. Only legally married spouses (including recognized common law spouses from other states) can receive alimony under C.G.S. § 46b-82. Unmarried partners must rely on enforceable written agreements to claim support.
How long do I have to live together to be common law married?
In Connecticut, no length of cohabitation creates common law marriage because Connecticut does not recognize the institution. In states that do allow common law marriage, there is no specific minimum duration requirement. The focus is on mutual agreement to be married and holding yourselves out publicly as married, not merely cohabitation duration.
Do children affect common law marriage recognition?
Having children together does not create a common law marriage in Connecticut or any other state. However, children born during a valid common law marriage (established in a state recognizing such unions) are legitimate and entitled to child support and custody determinations during divorce proceedings. Parental rights exist independently of marital status.
What is the waiting period for divorce in Connecticut?
Contested divorces face a 90-day waiting period from the return date under C.G.S. § 46b-67. However, Public Act 23-46 allows couples who reach full agreement on all issues to potentially finalize divorce on the return date. The nonadversarial process under C.G.S. § 46b-44a can complete in approximately 35 days for qualifying couples meeting strict eligibility criteria.
