A common law spouse (or “common law partner”) is someone who is legally recognized as married under common-law marriage rules, even though they never had a formal marriage ceremony or license. In states that recognize common law marriage, these spouses generally have many of the same legal rights and obligations as couples who went through a traditional marriage.
Here’s a breakdown of the key entitlements and protections a common law spouse might have, and when those rights apply.
Property Rights
- Division on Separation or Divorce: In states that allow common law marriage, a valid common law spouse may be entitled to property division just like in a formal marriage.
- Community Property States: If you are common-law married in a community-property state (like Texas), then assets acquired during the marriage may be treated as community property.
- Separate Property Considerations: In common-law (non-community property) states, property each spouse acquired separately may remain separate; courts look at a “totality” of assets.
Inheritance Rights
- If a common law spouse dies without a will (intestate), the surviving spouse may have the right to inherit as a “spouse,” depending on state law.
- Even in states that don’t currently allow new common law marriages, a common law marriage formed earlier may still give inheritance rights.
Spousal Support / Alimony
- In many states, a common law spouse may be eligible for spousal support (alimony) if the relationship ends, just like in a traditional marriage.
- Courts will treat the common law spouse similarly to a “formal” spouse when deciding maintenance, based on the couple’s finances, length of relationship, and other factors.
Estate & Probate Rights
- A common law spouse may make claims in probate court—for example, to a share of the deceased partner’s estate.
- They also may have rights to a life estate or a “marital life estate” if the laws or a will grant such an interest.
Federal & Tax Benefits
- For federal income tax, the IRS treats a valid common law marriage the same as a traditional marriage.
- In community-property states, federal tax rules may also rely on the marital status (including common law) to split or report income.
- Common law spouses may file joint tax returns, which can affect tax liability, deductions, credits, etc.
Social Security & Other Benefits
- A common law spouse may be eligible for Social Security spousal benefits, survivor benefits, or other spousal entitlements if their marriage is valid under state law.
- They may also qualify for pension or retirement benefits, if the employer’s plan treats them like any other married spouse.
Parental / Family Law Rights
- In a dissolution (divorce) or separation, a common law spouse has rights just as a formal spouse would: child custody, child support, and parental rights may be enforceable.
- They can make decisions (or share in decision-making) about children, similar to any married parent.
Recognition Across State Lines
- Thanks to the Full Faith and Credit Clause of the U.S. Constitution, a common law marriage that’s valid in one state is generally recognized by other states, even if those states don’t allow new common law marriages.
- That means the rights listed above (inheritance, property, etc.) can often travel with you when you move, if the marriage was validly formed originally.
⚖️ Important Caveats & Challenges
- Proving the Marriage: Because there’s often no marriage certificate, common law spouses may need to provide strong evidence: joint bank accounts, shared leases, tax filings, public representation, etc.
- State Differences: Not all states recognize common law marriage (or do so only under limited conditions).
- Legal Risk: If a court doesn’t accept that a valid common law marriage existed, you may lose out on the rights listed above.
- Documentation: To protect your rights, it’s wise to keep clear records (mail, financial statements, joint accounts, affidavits from friends/family) that show you were living as a married couple.
Frequently Asked Questions (FAQ)
Q1: Can a common law spouse force a divorce?
Yes — in most states that recognize common law marriage, you must go through a formal divorce just like in a traditional marriage to end the legal relationship.
Q2: If my partner dies, do I automatically inherit everything?
Not necessarily “everything,” but as a legally recognized common law spouse, you may be entitled to a portion of their estate under intestacy laws or their will—just like any other spouse.
Q3: Can my common law spouse get Social Security benefits?
Yes — if your common law marriage is valid under state law, many federal benefits, including Social Security spousal or survivor benefits, may apply.
Q4: Do I need to file taxes together with my common law spouse?
You can file jointly (if the state recognizes the marriage), which may offer tax advantages. But you should consult a tax professional — your situation (income, deductions, credits) matters.
Q5: What if I move to a state that doesn’t allow common law marriage? Do I lose my rights?
No — if your common law marriage was valid in the state where you formed it, other states generally must recognize it under the Full Faith and Credit Clause.
Final Thoughts
A common law spouse is not just a “partner”: legally, in many cases, they are just as entitled to rights and obligations as a formally married spouse. Those rights can include property division, inheritance, support, tax benefits, and more.
But because the marriage isn’t documented in a traditional way, proving your status can be tricky — and the details depend heavily on the state. If you believe you’re in a common law marriage, or if you want to secure your rights, it’s smart to talk to a qualified family-law attorney in your state.
