To check if you are married, work through two questions in order: was a legally valid marriage ever created between you and the other person, and has it been ended by divorce, annulment, or death? If a valid marriage was formed and no court has dissolved it, you are still married, even if you have lived apart for years and think of yourself as single. The answer usually lives in vital records, but common law relationships, foreign ceremonies, and marriages that may have been void from the start can complicate it.
Look for a Marriage Record First
The cleanest proof is a marriage certificate issued by a government office. In a typical ceremonial marriage, the couple applied for a license at a county clerk’s office, provided identification, paid a fee that generally runs between $35 and $100, had the ceremony performed by an authorized officiant, and the completed license was returned to the issuing office for recording. Once recorded, certified copies can be requested from that office.
If you are not sure whether a ceremony you participated in was ever properly recorded, contact the vital records office in the county or state where the ceremony took place and request a search. That search will tell you whether a marriage was recorded, when, and to whom.
When a certificate cannot be located, other records can help establish that a marriage exists. Joint tax returns, shared bank or mortgage accounts, property deeds listing both names, insurance policies naming each other as beneficiaries, and legal name-change records all serve as supporting evidence. The Social Security Administration, for its part, requires original documents or agency-certified copies to process a name change after marriage; photocopies and notarized copies are not accepted.1Social Security Administration.

Since the Supreme Court’s 2015 decision in Obergefell v. Hodges, every state must license marriages between two people of the same sex and recognize same-sex marriages performed in other states.2Justia. Obergefell v. Hodges, 576 U.S. 644 (2015) A same-sex marriage on record carries the same legal weight as any other. Civil unions and domestic partnerships entered before 2015 are not automatically treated as marriages for federal purposes; a marriage license had to be obtained afterward.
Could a Common Law Marriage Apply?
You might be legally married without ever having had a ceremony or a license. About six states still recognize new common law marriages, and several others honor common law marriages that were established before the state changed its law. Requirements vary, but recognizing states generally look for three things: an agreement or mutual intent to be married, living together as a couple, and publicly holding yourselves out as spouses through things like a shared last name, referring to each other as husband or wife, or filing joint tax returns.
A valid common law marriage is every bit as binding as a ceremonial one. It carries the same property rights, the same inheritance protections, and the same obligations. And here is where people routinely get tripped up: ending a common law marriage requires a formal divorce. Moving apart or deciding the relationship is over does not dissolve it. Until a court grants a divorce, you remain legally married, with all the tax filing obligations, debt exposure, and benefit eligibility that entails.
Disputes over whether a common law marriage actually existed tend to be messy. The person claiming the marriage bears the burden of proving it. Shared leases, joint accounts, affidavits from people who knew the couple socially, and testimony about how the couple presented themselves all come into play.
Marriages Performed Outside the United States
A marriage performed outside the United States is generally recognized here if it was valid under the laws of the country where it took place. This is called the “place of celebration” rule, and it applies across federal agencies including USCIS and the IRS.3U.S. Citizenship and Immigration Services. Chapter 2 – Marriage and Marital Union for Naturalization
There are exceptions. The federal government does not recognize polygamous marriages even if they are legal where performed. Proxy marriages, where one party was not physically present at the ceremony, are not recognized unless the marriage was later consummated. A marriage entered solely to evade immigration laws is treated as invalid regardless of where or how it was performed.3U.S. Citizenship and Immigration Services. Chapter 2 – Marriage and Marital Union for Naturalization
To prove a foreign marriage to a U.S. agency, you will typically need an authenticated or apostilled copy of the foreign marriage certificate. Countries that are part of the Hague Apostille Convention issue an apostille through their foreign affairs ministry, which makes the document usable in the United States without further authentication. For countries outside the convention, the document usually must go through the local U.S. embassy or consulate for authentication.
Reasons the Marriage May Never Have Been Valid
Not every ceremony produces a valid marriage. Some unions are void from the start, meaning they never legally existed. The most common reasons a marriage is void include bigamy (one spouse was already married to someone else), a close family relationship between the spouses, or the complete absence of a legal ceremony where one was required. No court order is needed to “end” a void marriage because there is nothing to end, though courts sometimes issue a formal declaration to resolve disputes over property or custody.
An annulment is different. It is a court order declaring that a marriage that appeared valid was actually defective and should be treated as if it never existed. Grounds typically include fraud or misrepresentation, one spouse lacking mental capacity to consent, one spouse being underage without proper consent, or coercion. Each jurisdiction sets its own grounds and time limits, so the window to file can be narrow.
If you entered a marriage believing in good faith it was valid and it turns out to have been void, you may qualify as a “putative spouse” in jurisdictions that recognize this doctrine. A putative spouse is entitled to share in marital property rights alongside the legal spouse.
Children born during a void or annulled marriage do not lose their legal status. Most states have statutes providing that a child born of a marriage later declared void is considered the legitimate child of both parents, often without any court action required, as long as at least one parent entered the marriage in good faith.4Social Security Administration.

Separated Is Not Divorced
This trips people up more than almost anything else. If you are separated from your spouse but do not have a final decree of divorce or separate maintenance, you are still legally married. The IRS treats you the same way: without a final court decree, you are considered married on December 31, and your filing options are limited to married filing jointly or married filing separately.5Internal Revenue Service. Filing Taxes After Divorce or Separation Living in different states, splitting finances, or thinking of yourselves as single does not change that.
The practical check is simple: pull the final divorce decree. If you cannot produce one, and no court has entered one, the marriage still exists. If you believe a divorce was filed but you never received the final paperwork, the clerk of the court where the case would have been filed can search their docket for any judgment.
Ask a Court to Decide When It Is Genuinely Unclear
When the question cannot be resolved through documents alone, because records are missing, a common law marriage is disputed, or one party claims the marriage was void, you can ask a court for a definitive answer. This typically involves filing a petition for a declaratory judgment in family court, where a judge reviews the evidence and issues a binding ruling on whether a valid marriage exists.
Courts look at everything available: marriage certificates and licenses, joint financial records, testimony from witnesses who knew the couple, evidence of cohabitation and how the couple presented themselves publicly, and any documentation suggesting the marriage was defective from the start. In common law marriage disputes, testimony from friends, family, and neighbors about how the couple held themselves out can carry substantial weight. The court’s decision resolves the question for all legal purposes going forward.
Why the Answer Matters
Marital status decides more than a checkbox on a form. For federal tax purposes, whatever your status is on December 31 is your status for the entire year, with no proration.6Internal Revenue Service. Filing Status For 2026, the standard deduction for a married couple filing jointly is $32,200, compared to $16,100 for a single filer.7Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026 Filing the wrong status in either direction can produce back taxes, penalties, and interest. Filing a joint return also makes both spouses jointly and severally liable for the entire tax debt, meaning the IRS can collect the full amount from either spouse regardless of who earned the income.8Office of the Law Revision Counsel. 26 U.S. Code 6013 – Joint Returns of Income Tax by Husband and Wife
Social Security benefits turn on marriage duration. You generally need to have been married for at least one year to collect spousal benefits on a living spouse’s record, at least nine months before death for survivor benefits, and at least ten years to collect on an ex-spouse’s record after divorce.9Social Security Administration.
