Louisiana does not recognize common law marriage. No matter how many years you live together, share bills, or introduce each other as spouses, the state will not treat you as legally married unless you obtained a marriage license from a parish clerk of court and had the ceremony performed by an authorized officiant.1Louisiana State Legislature. Louisiana Revised Statutes Title 9 – Marriage License That leaves unmarried couples without automatic rights to each other’s property, inheritance, medical decisions, and most government benefits. Closing that gap in Louisiana takes deliberate paperwork.
Why Louisiana Refuses to Recognize It
Louisiana is the only state whose private law comes from the French civil law tradition rather than English common law. Civil law treats marriage as a formal act that has to follow specific legal steps, so the license and the officiated ceremony are not optional. Skip either one and the state does not consider you married, regardless of how the relationship looks from the outside.
The consequences are broad. Married couples in Louisiana automatically fall under the state’s community property regime, which treats most assets and debts acquired during the marriage as belonging equally to both spouses.2Vernon Parish Chamber of Commerce. Louisiana’s Community Property Law Unmarried partners get none of that. Each person owns only what is titled in their name, and neither owes the other spousal support if the relationship ends. Louisiana’s intestacy rules are equally strict: property of someone who dies without a will passes to descendants, parents, siblings, and other blood or adopted relatives, along with a surviving spouse. An unmarried partner is not in that hierarchy at all.3Louisiana State Legislature. Louisiana Civil Code Art. 880 – Intestate Succession
The One Exception: Common Law Marriages From Other States
Louisiana will honor a common law marriage that was validly formed in a state that recognizes them. The Full Faith and Credit Clause of the U.S. Constitution requires every state to respect the legal acts of other states, and Louisiana courts apply that principle here.4LouisianaLawHelp.org. Common Law Marriage In Louisiana If you and your partner established a common law marriage while living in Colorado, Texas, Kansas, or another state that allows them, moving to Louisiana should not dissolve that marriage.
The burden is on you to prove it. You need to show the relationship met the legal requirements of the state where the marriage was formed, which typically include mutual agreement to be married, cohabitation, and holding yourselves out publicly as a married couple. Joint bank accounts, shared leases, joint tax filings, and using the same last name all help.
This matters beyond Louisiana law. The Social Security Administration recognizes common law marriages formed in states that allow them, so a surviving partner from a valid common law marriage can claim survivor and spousal benefits. The SSA looks at whether the marriage was contracted in a state where common law marriage is legal and whether both parties intended a permanent, exclusive union.5Social Security Administration. Common-Law Marriage – General If the marriage does not hold up on those terms, the benefits are gone.
What Unmarried Partners Lose By Default
Understanding the default rules makes clear why the paperwork below is worth doing.
Property
Without community property, ownership follows the title. If your name is not on the deed, you have no automatic claim to the house, even if you paid half the mortgage for a decade.2Vernon Parish Chamber of Commerce. Louisiana’s Community Property Law Couples who buy property together should put both names on the deed. Even then, if co-owners cannot agree on what to do with the property, either one can file to partition it. If it cannot be physically divided, which is the usual outcome with a house, the court orders a sale and splits the proceeds by ownership share.6Louisiana State Legislature. Louisiana Civil Code Art. 811 – Partition by Licitation or by Private Sale The process is slower and less predictable than the community property division married couples go through in a divorce.
Workers’ Compensation and Other Benefits
Louisiana workers’ compensation law expressly excludes unmarried partners from death benefits. The statute says no payments go to a “concubine” of the deceased employee, regardless of financial dependence, and children of the unmarried partner are excluded unless they were related to the deceased worker by blood or adoption.7Louisiana State Legislature. Louisiana Revised Statutes 23:1253 – Membership in Family or Relationship Federal survivor benefits generally require a legal marriage as well; the Social Security workaround described above is the main exception.
Taxes
Unmarried couples cannot file a joint federal return. The IRS bases filing status on marital status as of the last day of the tax year, and joint filing is only available to married couples.8Internal Revenue Service. Filing Status Transfers between partners also face gift tax rules that spouses avoid entirely through the marital deduction. For 2026, the annual gift tax exclusion is $19,000 per recipient, and amounts above that count against your lifetime estate and gift tax exemption.9Internal Revenue Service. Estate and Gift Tax One partner paying for a major renovation or covering the other’s debts can create tax obligations most couples never see coming.
Hospital and Funeral Decisions
Hospital visitation policies during emergencies often default to “immediate family,” which does not include an unmarried partner. Burial follows a strict statutory hierarchy: surviving spouse, then a majority of adult children, then parents, then siblings, and outward. An unmarried partner is nowhere on that list. Without written instructions from the deceased, the partner has no legal say in funeral arrangements.
How to Close the Gap
Everything unmarried couples lose by default can be addressed with contracts and estate documents. Doing it while both partners are healthy and getting along is far easier than trying to fix things after a crisis.
Cohabitation Agreements
A written cohabitation agreement is the single most useful document. It spells out how you handle property, finances, and shared expenses during the relationship, and what happens if you split up. Louisiana once restricted some agreements and gifts between cohabitants, but that prohibition was repealed decades ago, and these contracts are now enforceable.
A solid agreement covers who owns which property, how shared expenses are divided, what happens to jointly purchased assets at separation, and whether either partner will provide financial support to the other afterward. Neither partner has any right to support without a written agreement to that effect. There is no required format, but having the document drafted or reviewed by an attorney and signed before a notary strengthens its enforceability.
Wills and the Forced Heirship Rule
A will is the only way to make sure your partner inherits anything, since intestacy leaves them with nothing.3Louisiana State Legislature. Louisiana Civil Code Art. 880 – Intestate Succession Louisiana adds a wrinkle most states do not: forced heirship. Children who are 23 or younger at your death, and children of any age who are permanently incapable of caring for themselves, are forced heirs entitled to a portion of your estate that you cannot leave to anyone else.10Justia. Louisiana Civil Code Art. 1493 – Forced Heirs If you have forced heirs, the share available to leave to a partner is limited to the “disposable portion” of the estate. A will that ignores this can be partially overturned.
Revocable living trusts add flexibility, particularly for managing assets if you become incapacitated. Assets placed in a trust bypass the succession process entirely, which can mean faster access for a surviving partner and fewer openings for family members to challenge the arrangement.
Powers of Attorney and Healthcare Directives
Louisiana law gives an unmarried partner no default authority to handle your finances or medical care if you become incapacitated. A durable power of attorney, called a “mandate” in Louisiana, lets you name your partner as the person authorized to manage your financial affairs.11Louisiana State Legislature. Louisiana Civil Code Art. 2989 – Mandate Defined A separate healthcare declaration, sometimes called an advance directive, lets you name your partner as your healthcare agent. Both have to be signed while you are competent; a medical crisis is too late, and a court may appoint a family member instead.
Hospital Visitation Designation and Burial Instructions
Louisiana law allows any person 18 or older to designate individuals who cannot be denied hospital visitation.12Louisiana State Legislature. Louisiana Revised Statutes 40:1300.54 – In-Person Visitation Policies; Requirements Filing a visitor designation with the hospital at admission avoids the “immediate family only” problem. For funeral decisions, a written and notarized declaration specifying your burial wishes and naming your partner as the person in charge is the only way to override the statutory hierarchy.
Paternity for Unmarried Parents
When unmarried parents have a child, the mother is automatically a legal parent. The father is not, and he has no rights to custody, visitation, or decision-making until paternity is established. The simpler route is a voluntary acknowledgment of paternity signed by both parents as an authentic act. It carries the same legal weight as a court order, immediately establishes the father’s support obligation and rights to custody and visitation, and secures the child’s right to inherit from him. Either parent can request genetic testing before signing.13Justia. Louisiana Revised Statutes 9:392 – Acknowledgment; Requirements; Content Once signed, the acknowledgment supports child support and visitation without a separate court judgment.14Justia. Louisiana Revised Statutes 9:392.1 – Acknowledgment; Obligation to Support; Visitation
If the parents cannot agree, paternity can be established through a court action where a judge orders genetic testing. Skip both routes and the father has no standing to seek custody or visitation, and no legal recourse if the mother relocates with the child.
One Area Where Being Unmarried Does Not Matter
Louisiana’s Domestic Abuse Assistance Act applies to household members and dating partners, not just spouses. A “household member” includes anyone presently or formerly living in the same residence who is or was in a sexual or intimate relationship with the abuser.15Louisiana State Legislature. Louisiana Revised Statutes 14:35.3 – Domestic Abuse Battery A victim can request an emergency temporary restraining order without the abuser being notified, and the court can grant one on a showing of immediate and present danger of abuse.16Louisiana State Legislature. Louisiana Revised Statutes 46:2135 – Temporary Restraining Order After a full hearing within 21 days, the court can issue a protective order lasting up to 18 months, with extensions available.17Louisiana State Legislature. Louisiana Revised Statutes 46:2136 – Protective Orders The process is the same whether you are married, dating, or formerly cohabiting.
