Prenuptial Agreement in
Louisiana
Louisiana operates under a civil law tradition inherited from its French and Spanish heritage, and its marital property system is distinct from every other state in the country. What other states call a prenuptial agreement, Louisiana calls a "matrimonial agreement," and it is governed by the Louisiana Civil Code rather than the UPAA or UPMAA. Louisiana is a community property state, and without a matrimonial agreement, spouses are automatically subject to the legal regime of community property; a matrimonial agreement can establish a regime of separation of property or modify the community regime for specific assets.

How Louisiana handles marital property
Louisiana is a community property state. Property acquired during the marriage is generally owned equally by both spouses under Louisiana's civil law tradition.
Legal framework
State-specific (Civil Law) in Louisiana
Louisiana follows its own civil law framework for prenuptial agreements (called "matrimonial agreements"). These must be made by authentic act (notarized) or by act under private signature duly acknowledged. They must be executed before the marriage.
Louisiana is the only U.S. state that follows a civil law system (based on French law) rather than common law. Prenuptial agreements here are called "matrimonial agreements" and have unique requirements. Consulting a Louisiana attorney is particularly important.
Requirements

Best practices
Tips for a strong prenup in Louisiana
Following these best practices helps ensure your agreement is clear, fair, and enforceable.
Louisiana's matrimonial agreement must be executed before a notary and two witnesses — this is a mandatory formality under the Civil Code, not just a best practice.
If you want to opt out of community property entirely, your agreement must affirmatively establish a regime of separation of property; simply not having a community agreement is not sufficient to avoid community property rules for property acquired after marriage.
Because Louisiana uses the Civil Code rather than common law, work with an attorney who is specifically licensed and experienced in Louisiana civil law marital property.
After marriage, you can modify a matrimonial agreement with court approval — plan your agreement carefully, but know that adjustments are possible if circumstances change significantly.
Revenue produced by separate property (such as rent from a pre-marital rental property) becomes community property under the default regime — address this explicitly if you want rental income to remain separate.
Cost
How much does a prenup cost in Louisiana?
The cost of a prenuptial agreement in Louisiana varies depending on how you create it and the complexity of your financial situation.

Per spouse. Involves multiple consultations, document drafting, negotiation rounds, and review. Each party typically needs their own attorney, so total costs can reach $5,000–$20,000+ for the couple.

Process
How to get a prenup in Louisiana
Follow these steps to create an enforceable prenuptial agreement that meets Louisiana's legal requirements.
Start the conversation early
Bring up the topic of a prenup with your partner well before the wedding — ideally at least 2–3 months ahead. The agreement must be executed before the marriage ceremony. It cannot be modified during the marriage without court approval in certain circumstances. Starting early shows both parties entered the agreement without pressure.
Gather your financial information
Both partners should prepare a complete picture of their finances: assets, debts, income, and any expected inheritances. Louisiana requires full financial disclosure for a prenup to be enforceable.
Draft the agreement
Create your prenuptial agreement using prenups.ai's guided questionnaire, which is specifically tailored to Louisiana's community property system and State-specific (Civil Law) requirements. The AI drafts a comprehensive, jurisdiction-aware document in minutes.
Review with independent attorneys
Two witnesses are required when the agreement is executed as an authentic act. While Louisiana may not strictly require each party to have their own attorney, independent legal review significantly strengthens enforceability and ensures both spouses understand the terms.
Sign and execute properly
Notarization is required. Louisiana law requires the agreement to be made by authentic act (before a notary and two witnesses) or by acknowledged private signature. Both parties must sign the agreement voluntarily. Keep the original in a safe place and provide copies to both spouses and their attorneys.

Common questions about prenups in Louisiana
Why does Louisiana use "matrimonial agreement" instead of "prenuptial agreement"?
Louisiana follows the civil law tradition and its family law is codified in the Louisiana Civil Code, which uses the term "matrimonial agreement" for what other states call a prenup. The agreement must be executed before a notary and two witnesses to be valid.
What is the default marital property regime in Louisiana without an agreement?
Without a matrimonial agreement, Louisiana spouses are automatically subject to the legal regime of community of acquests and gains, meaning most property and income acquired during the marriage belongs equally to both spouses.
Can a Louisiana matrimonial agreement establish separate property?
Yes. A matrimonial agreement can establish a regime of separation of property, under which each spouse retains individual ownership of property they acquire during the marriage rather than it becoming community property.
Can spouses modify a Louisiana matrimonial agreement after marriage?
Yes, but post-marriage modifications require court approval under Louisiana Civil Code Article 2329. Both spouses must petition the court and demonstrate that the modification serves their mutual interest.
Does Louisiana require a notary for a matrimonial agreement?
Yes. Under Louisiana Civil Code Article 2331, a matrimonial agreement must be made by authentic act, which requires execution before a notary public and two witnesses. An agreement that does not meet these formalities is not valid in Louisiana.
How much does a prenup cost in Louisiana?
Traditional attorney-drafted prenups in Louisiana typically cost $2,500–$10,000 per spouse, or $5,000–$20,000+ for the couple. Online services like prenups.ai offer AI-generated prenuptial agreements for $349 one-time, tailored to Louisiana's community property system. Many couples use an AI-generated draft as a starting point and then have it reviewed by a local attorney at a fraction of the traditional cost.
How long does it take to get a prenup in Louisiana?
With prenups.ai, you can have a draft prenuptial agreement in under 20 minutes. Traditional attorney routes in Louisiana typically take 2–6 weeks due to scheduling, drafting, negotiation, and review. The agreement must be executed before the marriage ceremony. It cannot be modified during the marriage without court approval in certain circumstances. We recommend starting the process at least 2–3 months before your wedding to allow time for review and any revisions.
Can I create a prenup without a lawyer in Louisiana?
Yes. Louisiana does not require you to have an attorney to create a valid prenuptial agreement. However, having each party consult with independent legal counsel significantly strengthens enforceability. Many couples use prenups.ai to create the initial draft and then have it reviewed by attorneys, which is much more affordable than starting from scratch.
What happens if I don't get a prenup in Louisiana?
Without a prenup, Louisiana's default community property rules apply. Louisiana is a community property state. Property acquired during the marriage is generally owned equally by both spouses under Louisiana's civil law tradition. A prenup lets you define your own terms instead of leaving these decisions to state law or a judge's discretion.
