In Louisiana, drafting a prenuptial agreement (matrimonial agreement) typically costs between $1,500 and $3,500. The price depends heavily on your net worth, the complexity of your assets, and whether you rush the process before the wedding.

Getting married in Louisiana means you are automatically entered into the state's 'Community of Acquets and Gains.' Under this system, almost everything you earn or buy during the marriage is split 50/50. To opt out of this default system, couples must sign a matrimonial agreement, commonly known as a prenuptial agreement or prenup. This contract establishes a separate property regime. While discussing legal fees before a wedding is never fun, understanding how Louisiana attorneys price these agreements can help you budget properly and protect your financial future. You can easily find a seasoned family lawyer in our directory to help draft your agreement.

Standard Attorney Fee Structures in Louisiana

Family law attorneys generally use two different billing methods: flat fees and hourly billing. The route your lawyer takes depends entirely on how complicated your financial life is and how much negotiating needs to happen between you and your future spouse.

Costs for Simple Separate Property Regimes

If you and your partner have standard W-2 jobs, simple retirement accounts, and simply want to ensure that your earnings remain separate, your attorney will likely offer a flat fee. For a straightforward matrimonial agreement, flat fees typically range from $1,500 to $2,500. This fee generally covers the initial consultation, drafting the contract, and executing the document as an 'Authentic Act' before a notary and two witnesses, as required by La. Civ. Code art. 2331. If you are filing in the Civil District Court for the Parish of Orleans, New Orleans or the 19th Judicial District Court, Baton Rouge, you will also pay a small fee to record the agreement in the parish conveyance records.

Costs for High-Net-Worth Individuals

If you own a business, have complex investments, or are bringing significant generational wealth into the marriage, a simple template will not work. High-net-worth prenups require extensive financial disclosures and customized clauses regarding spousal support (alimony) waivers. In these situations, lawyers usually charge an hourly rate ranging from $250 to $500 per hour. When both parties are negotiating back and forth to protect business valuations and real estate portfolios, the total cost can easily escalate to $4,000 to $7,000 or more. You may also need to pay extra to hire a forensic accountant to properly appraise your business before signing.

Hidden Costs of Rushed Agreements

One of the biggest mistakes couples make is waiting until the month of the wedding to contact a lawyer. Rushing a matrimonial agreement triggers 'rush fees' from your attorney, which can add $1,000 or more to your bill. More importantly, signing an agreement just days before walking down the aisle creates a massive legal vulnerability. A spouse could later argue in court that they signed the document under duress or coercion because the wedding invitations were already mailed. Judges in Louisiana scrutinize rushed agreements heavily, so it is best to start the process 3 to 6 months in advance.

Why Both Spouses Must Pay for an Attorney

To save money, couples often ask if one lawyer can write the agreement for both of them. This is a severe conflict of interest. For a matrimonial agreement to be ironclad, both spouses must have independent legal counsel. This ensures neither party is taken advantage of. While the wealthier spouse can physically pay the invoice for the other spouse's attorney, each party must have their own lawyer review the document. Therefore, if the primary drafting attorney costs $2,000, you should budget an additional $1,000 for the opposing attorney's review fees.

Frequently Asked Questions (FAQ)

Does a Louisiana prenuptial agreement have to be notarized?

Yes. Under Louisiana law, a matrimonial agreement must be made by an Authentic Act or by an act under private signature duly acknowledged. An Authentic Act means it is signed in front of a licensed notary public and two witnesses.

Do we have to file the agreement with the court?

To be effective against third parties (like creditors or banks), the agreement must be filed for registry in the conveyance records of the parish where you live, not necessarily in a standard court proceeding.

Can a prenup dictate child custody in Louisiana?

No. You cannot legally pre-determine child custody, visitation, or child support in a matrimonial agreement. Judges will always make these decisions at the time of a divorce based on the best interest of the child.

What happens if we do not sign a prenup?

If you marry without an agreement, you automatically fall under the Louisiana Community Property system. Any debt you take on and any money you earn during the marriage is equally shared by both spouses.
