A common-law spouse can collect Social Security benefits on a partner’s earnings record, but only if the marriage is valid under the law of the state where it was formed and you can prove that to the Social Security Administration. Spousal benefits reach up to 50 percent of the worker’s benefit at full retirement age; survivor benefits reach up to 100 percent. The rules for amounts, timing, and remarriage are the same as for any other marriage. The hard part is the proof.
When the SSA Recognizes a Common-Law Marriage
The SSA applies the law of the state where the common-law marriage was established, not the state where you live now. If you formed a valid common-law marriage in a recognizing state and later moved somewhere that requires a ceremony, the SSA still treats you as married.1Social Security. GN 00305.060 Common-Law Marriage — General
Every recognizing state sets its own requirements, but the common elements are mutual consent to be married, an intent to be married from that point forward, and holding yourselves out to others as a married couple. Some states also require cohabitation.2Social Security Administration. Code of Federal Regulations 404.726 – Evidence of Common-Law Marriage
Only a handful of jurisdictions still allow new common-law marriages to form. Several states that once recognized them have abolished the practice, though marriages validly created before the cutoff remain valid. The SSA will not tell you in advance whether your state qualifies; it evaluates that when you file.
Ignore the seven-year myth. No state creates a common-law marriage simply because a couple has lived together for a set number of years. If the state’s legal requirements are met, the marriage exists; if they aren’t, no amount of time together will create one.
Spousal Benefits
Once the SSA accepts your common-law marriage, spousal retirement benefits work the same way they do for any married couple. The maximum is 50 percent of the worker’s primary insurance amount, which is the benefit the worker earns at full retirement age.3Social Security Administration. Benefits for Spouses To qualify, you generally need to meet three conditions:
- You are at least 62, or you are caring for the worker’s child who is under 16 or disabled.4Social Security Administration. Who Can Get Family Benefits
- You have been married for at least one year, with an exception if you are the biological parent of the worker’s child.5Social Security Administration. What Are the Marriage Requirements to Receive Social Security Spouse’s Benefits
- The worker is receiving retirement or disability benefits.
Claiming before your full retirement age reduces the benefit permanently. Filing at 62 can drop the amount to as little as 32.5 percent of the worker’s primary insurance amount instead of 50 percent.3Social Security Administration. Benefits for Spouses
Deemed Filing
If you turned 62 on or after January 2, 2016, you cannot claim only a spousal benefit while letting your own retirement benefit grow. When you apply for one, the SSA deems you to have applied for both and pays you the higher amount.6Social Security Administration. Filing Rules for Retirement and Spouses Benefits Deemed filing does not apply to survivor benefits, so a surviving common-law spouse can take a survivor benefit at 60 and still delay their own retirement benefit until 70.
Survivor Benefits
If your common-law spouse dies, you may qualify for survivor benefits worth up to 100 percent of what they were receiving or entitled to receive. The earliest filing age is 60, which pays roughly 71.5 percent; the percentage rises for each month you wait, reaching 100 percent at your survivor full retirement age (between 66 and 67 for most people).7Social Security Administration. What You Could Get from Survivor Benefits
The marriage generally must have lasted at least nine months before the worker’s death.8Social Security Administration. Who Can Get Survivor Benefits Federal law waives that requirement in certain situations, including accidental death and deaths in the line of military duty.9Legal Information Institute. 42 USC 416(c)(1) – Definition of Widow The nine-month rule also does not apply if you are caring for the deceased worker’s child who is under 16 or disabled. If you have a qualifying disability, you can claim survivor benefits as early as age 50.10Social Security Administration. Survivors Benefits
Remarriage
Remarrying before age 60 generally ends survivor benefits on your deceased spouse’s record. Remarrying at 60 or older (or at 50 or older if you have a disability) does not affect them. From age 62, you can compare benefits available on a new spouse’s record and switch if they are higher.10Social Security Administration. Survivors Benefits
Divorced Common-Law Spouses
Ending a common-law marriage generally requires a formal divorce, the same as any other marriage. After divorce, you can claim benefits on a former spouse’s record if the marriage lasted at least 10 years, you are at least 62, currently unmarried, and your own retirement benefit is less than what you would receive on the ex’s record.11Social Security Administration. Code of Federal Regulations 404.331 – Who Is Entitled to Wife’s or Husband’s Benefits as a Divorced Spouse
If your ex has not filed for their own benefits yet, you also need to have been divorced for at least two continuous years before you can claim. That waiting period ends once they start collecting. Survivor benefits are also available to divorced common-law spouses when the 10-year marriage requirement is met.
The practical difficulty is proving the marriage years after the fact. Gathering the paperwork while you are still on decent terms is easier than reconstructing it after a contentious split.
Proving the Marriage to the SSA
The SSA does not take your word for it. It requires specific sworn statements and corroborating documents before recognizing a common-law marriage.
Sworn Statements
If both spouses are living, each completes Form SSA-754 (Statement of Marital Relationship), and a blood relative of each spouse completes Form SSA-753 (Statement Regarding Marriage). If one spouse has died, the surviving spouse files an SSA-754; two blood relatives of the deceased and one blood relative of the survivor each file an SSA-753.12Social Security Administration. GN 00305.065 – Development of Common-Law (Non-Ceremonial) Marriages
The forms ask detailed questions about when the relationship began, where you lived, how you introduced yourselves to others, and how long the person filling out the form has known you as a couple. Answers that conflict across the statements will slow the claim or sink it.
If blood relatives cannot be located or refuse to participate, the SSA will accept a statement from another person with knowledge of the marriage, provided you submit a written explanation of why the relative’s statement is unavailable. A prior state court or administrative ruling establishing the common-law marriage can serve as evidence on its own.12Social Security Administration. GN 00305.065 – Development of Common-Law (Non-Ceremonial) Marriages
Supporting Documents
Beyond the sworn statements, the SSA looks for records showing you lived as a married couple. Useful items include mortgage or rent receipts with both names, insurance policies naming each other as beneficiaries, medical records, and joint bank accounts. Joint federal tax returns filed as “married filing jointly” carry particular weight, because the IRS also treats a state-valid common-law marriage as a marriage for federal tax purposes.13Internal Revenue Service. Revenue Ruling 2013-17 The SSA notes that this list is not exhaustive; anything showing you held yourselves out as married can help.12Social Security Administration. GN 00305.065 – Development of Common-Law (Non-Ceremonial) Marriages
Consistency matters. If you have been filing tax returns as single or head of household while considering yourself married, expect the SSA to ask about it.
How to Apply
You can apply online, by phone, or in person, but for common-law marriage claims an in-person visit is usually the most practical route because the SSA will want to review originals and may interview you about the marriage evidence.
Bring the completed SSA-753 and SSA-754 forms, birth certificates, joint tax returns, insurance policies, property records, and anything else that supports the marriage. The SSA accepts only originals or certified copies issued by the originating agency, not photocopies or notarized copies. Originals are returned after the agency makes its own copies.14Social Security Administration. GN 00301.275 – Retention or Return of Documents
Scheduling an appointment before you visit a field office cuts down on wait times. You can book one by calling 1-800-772-1213.
If the SSA Denies the Claim
A denial can be appealed. You can request reconsideration first, where a different SSA employee reviews the file. If reconsideration fails, you can request a hearing before an administrative law judge, and beyond that the Appeals Council.15Social Security Administration. Appeal a Decision We Made
Common-law marriage denials usually come down to thin or contradictory evidence rather than the underlying legal question. Read the denial closely to see what the SSA found insufficient, then gather stronger corroborating documents or additional witness statements before you appeal. Resubmitting the same package rarely changes the result.
