Louisiana is a community property state
Louisiana is a community property state — all property acquired during marriage belongs equally to both spouses under the community property regime. A prenup is especially important in Louisiana — without one, all income and assets earned during the marriage are automatically split 50/50 regardless of who earned them.
Prenup Cost in Louisiana — Full Breakdown
| Option | Cost in Louisiana | Best for |
|---|---|---|
| Two separate attorneys (one per spouse) | $1,000–$5,500 | Complex assets, business ownership, high net worth, or prior marriages |
| One attorney drafts; second reviews | $550–$3,025 | Moderate assets; one party takes the lead on drafting |
| Online platform (HelloPrenup) | $599/couple | Straightforward finances, combined assets under $500K, no children from prior relationships |
| DIY template (not recommended) | $0–$99 | Not recommended — enforceability risk without attorney review |
Louisiana attorneys typically bill $150–$325/hour for family law matters. A standard prenup requires 7–18 hours of attorney time per side — covering the initial consultation, drafting, negotiation, revisions, and signing.

Key enforcement note
Louisiana is a community property state with strict notarization requirements. Prenups (called 'matrimonial agreements') must be executed in authentic form — notarized before a notary AND signed in the presence of two witnesses. An informally signed agreement is legally void.
What Makes a Louisiana Prenup More Expensive
Attorney cost varies within the $1,000–$5,500 range based on complexity:
Business ownership
Valuing and protecting a business interest in a Louisiana prenup adds significant complexity — potentially requiring a business valuation expert and more detailed drafting provisions.
Adds $1,000–$3,000+
Real estate
If either party owns real estate in multiple states, each property's treatment must be addressed under the relevant state's laws.
Adds $500–$2,000
Prior marriage or children
Protecting children from a prior relationship requires careful estate planning integration — often a separate process running alongside the prenup.
Adds $500–$2,000
Negotiation and revisions
If the parties disagree on terms and require multiple rounds of revision, attorney fees increase proportionally. The simple estimates assume 2–3 drafts.
Variable — $300–$500/round
Attorney location
Attorneys in Louisiana's major metros (especially the state's largest cities) typically bill 65–163 more per hour than suburban or rural attorneys.

Is Louisiana a community property state?

How far in advance should I sign a prenup in Louisiana?
Family law attorneys recommend finalizing your Louisiana prenup at least 30–60 days before the wedding, and ideally 3–6 months in advance. Courts look unfavorably on prenups signed within days of the wedding, viewing them as potentially coercive.
Can I do a prenup without a lawyer in Louisiana?
