There is no such thing as a common law marriage certificate issued by a state or county at the moment the marriage begins, because a common law marriage forms through the couple’s agreement and conduct rather than through a filing. To get something that functions as a certificate, you either file a sworn declaration with a county clerk in a state that offers one, ask a court to issue an order recognizing the marriage, or assemble an evidence file that federal agencies and courts will accept as proof.
Why No Certificate Is Issued
A ceremonial marriage produces a certificate because the couple applied for a license before the wedding and an officiant signed the record afterward. A common law marriage skips both steps. It comes into existence when two people agree to be married, live together, and hold themselves out as spouses. No government office was involved at the start, so no certificate sits on file waiting to be requested.
What people searching for a certificate actually need is proof. Depending on the state and the situation, that proof is a signed declaration recorded with a county clerk, a court order recognizing the marriage, or a well-organized set of supporting documents. Each of these functions as your marriage certificate for legal and administrative purposes.
Whether Your State Allows a Common Law Marriage
Only a handful of jurisdictions still permit new common law marriages to form. If the couple lived exclusively in a state that doesn’t allow them, no amount of evidence creates one.
The states that broadly recognize new common law marriages are Colorado, Iowa, Kansas, Montana, South Carolina, and Texas. Oklahoma and Rhode Island recognize them through case law rather than statute.1National Conference of State Legislatures. Common Law Marriage by State Utah takes a different approach: a couple must petition a court or administrative body for a formal order recognizing the relationship, and the petition has to be filed during the relationship or within one year after the couple separates or one partner dies. New Hampshire recognizes common law marriage only for inheritance, when a couple cohabited and were generally known as married for at least three years and one partner has died.
Several states that abolished common law marriage still honor unions formed before a cutoff. Pennsylvania recognizes those created before January 1, 2005, Ohio before October 10, 1991, and Indiana before January 1, 1958.1National Conference of State Legislatures. Common Law Marriage by State If your relationship began after your state’s cutoff, no proof will make it valid.
What You Have to Prove
Before pursuing formal documentation, confirm that your relationship meets the requirements. The specifics vary by state, but recognizing jurisdictions look for the same core elements.2Social Security Administration. POMS GN 00305.060 – Common-Law Marriage – General
- A mutual, present-tense agreement to be married. A promise to marry someday doesn’t count, and once made the agreement can only be ended by death, divorce, or annulment.
- Legal capacity. Both partners must be at least 18 and free to marry, meaning neither is currently married to someone else. An undissolved prior marriage, including a prior common law marriage, makes any new marriage void.
- Cohabitation. The couple must actually live together. No state sets a minimum duration.
- Holding out as married. You must present yourselves to the community as spouses, and people outside the relationship must have understood you that way.
- Formation in a recognizing state. The marriage has to originate somewhere that permits it.
Filing an Administrative Declaration
The closest thing to a traditional certificate comes from states that let a couple record a sworn declaration with the county clerk. Texas is the clearest example. Both partners appear in person and swear under oath that they agreed to be married, have been living together in the state, and have represented themselves to others as married. The clerk files the Declaration of Informal Marriage and forwards a copy to the state’s vital statistics bureau.3Texas Department of State Health Services. Declaration and Registration of Informal Marriage Once recorded, that declaration is prima facie evidence of the marriage: it’s presumed valid unless someone proves otherwise.
This route is fast and inexpensive. Filing fees for marriage-related declarations generally run between $15 and $62 depending on the county. The limitation is that both partners have to agree and appear together. If one partner disputes the marriage or has died, the administrative option isn’t available.
Getting a Court Order
A judicial decree is the other way to obtain formal documentation, and it’s the only option when the marriage is contested, when a partner has died and surviving family members dispute the relationship, or when the marriage comes up in divorce or probate.
You file a petition in state court asking the judge to recognize the common law marriage. This can happen inside a divorce case, a probate proceeding, or a standalone declaratory judgment action. The petitioner has to prove every required element through testimony, documents, and witnesses. A resulting order is the strongest possible proof.
Timing matters. In Texas, if a legal proceeding to prove the marriage isn’t started within two years of the date the couple separated, a rebuttable presumption arises that no agreement to marry ever existed.4State of Texas. Texas Family Code Title 1 Subtitle A Chapter 2 Subchapter E Section 2-401 The presumption can be overcome, but it makes the case significantly harder. Utah’s window is tighter: petitions must be filed during the relationship or within one year after separation or death. Missing that window means losing judicial recognition entirely.
Building the Evidence File
Whether you’re filing a declaration, going to court, or preparing for the day you’ll need to prove the marriage to an agency, the strength of your claim depends on documentation. Gather as much of the following as possible:
- Joint tax returns filed as “married filing jointly.” This is among the strongest evidence because it’s a sworn statement to the government.
- Financial records showing interdependence: joint bank accounts, shared credit cards, co-signed loans, and mortgages in both names.
- Property records such as deeds, vehicle titles, or leases listing both partners.
- Insurance and benefits records: life insurance naming the other partner as beneficiary, health plan enrollment as spouses, emergency contact designations.
- Estate planning documents that refer to the other person as a spouse, including wills, powers of attorney, and healthcare directives.
- A shared last name and documents reflecting any name change.
- Signed statements from family, friends, or community members confirming they understood you to be married.
The most practical single step you can take now is to write and sign a dated statement together declaring that you consider yourselves married, intend the relationship to be permanent, and have lived together since a specific date. Have it notarized. It isn’t a legal requirement, but a contemporaneous written agreement is far more persuasive than testimony reconstructed years later.
Using Your Proof With Federal Agencies
Federal agencies generally recognize a common law marriage if it’s valid under the law of the state where it was formed, but each agency runs its own verification.
Social Security
Social Security applies the marriage laws of the state where the couple lived when the worker filed for benefits or died. If that state recognizes common law marriage, the agency evaluates the claim using evidence similar to what a court would consider.2Social Security Administration. POMS GN 00305.060 – Common-Law Marriage – General The preferred proof is signed statements from both spouses, or from the surviving spouse, plus statements from two blood relatives confirming the marriage.5Social Security Administration. Code of Federal Regulations 404.726 If blood relatives aren’t available, statements from other people who knew the couple can substitute. The SSA also uses Form SSA-753, which asks third parties whether the couple was generally known as married, lived together continuously, and referred to each other as spouses.6Social Security Administration. Statement Regarding Marriage – Form SSA-753
Employment and Other Federal Benefits
FMLA regulations define “spouse” to include a husband or wife recognized through common law marriage, and COBRA continuation coverage and HIPAA enrollment rights apply the same way. If an employer questions marital status, a joint tax return or signed affidavit is typically enough. The State Department also recognizes common law marriages for purposes such as passport applications, using its own declaration form that asks for proof of common residency and financial interdependence.
Moving to Another State
A common law marriage validly created in a recognizing state will generally be honored in every other state, including those that don’t allow new ones. Courts across the country routinely recognize common law marriages formed elsewhere, so a couple who married under Colorado law and later moved to California is still married in California’s view. Complications arise only when the validity of the original marriage is disputed. If you can’t prove the marriage met the requirements of the state where it began, another state has no obligation to recognize it. That’s one more reason to build a strong evidence file even if you never plan to leave.
Ending the Marriage
A common law marriage carries exactly the same legal weight as a ceremonial one, which means it can only be dissolved by a formal divorce or annulment. There is no “common law divorce.” Separating, moving apart, or dropping a shared last name does not end the marriage.
The divorce process is identical to any other: filing a petition, completing financial disclosures, dividing property, and obtaining a final decree. If the marriage itself is disputed, the court must first hold an evidentiary hearing to determine whether a marriage existed before granting the divorce.
The stakes of skipping this step are serious. Marrying someone new without dissolving an existing common law marriage can constitute bigamy, a criminal offense in most states. The first spouse also retains marital property rights, so assets acquired during a later relationship, including a house, retirement accounts, and savings, may be partially claimed. If you believe a common law marriage ever existed in your relationship, get a formal divorce before entering a new one, even if years have passed since the separation.
