Authentic acts, as defined in Article 1833 of the Louisiana Civil Code, are writings executed before a Notary Public, in the presence of two competent witnesses, and signed by each party, witness, and the Notary. These acts carry a high evidentiary value, serving as full proof of the agreement they contain.
What is an Authentic Act in Louisiana for a Notary Public?
If you’ve ever dealt with legal documents in Louisiana, you may have heard the term Authentic Act thrown around. But what does it actually mean? And why is it so important?
Unlike other states, Louisiana follows civil law traditions rather than common law. This means that legal documents are treated differently here. One of the most powerful and legally binding documents you can create in Louisiana is called an Authentic Act, which requires a notary public and two witnesses to be valid.
In this guide, we’ll break down:
✅ What an Authentic Act is
✅ Why it matters
✅ When you need one
✅ How to properly execute an Authentic Act
✅ Common mistakes to avoid
By the end, you’ll have a solid understanding of this essential legal tool and how it plays a role in real estate transactions, wills, contracts, and other agreements in Louisiana.
What is an Authentic Act?
In simple terms, an Authentic Act (or Acte Authentique) is a legal document that has been executed in the presence of a notary public and two competent witnesses. It’s considered the highest form of written proof under Louisiana law, meaning it holds more weight than other types of legal documents.
Here’s how Louisiana Civil Code Article 1833 defines it:
“An authentic act is a writing executed before a notary public or other officer authorized to perform that function, in the presence of two witnesses, and signed by each party who executed it, by each witness, and by the notary public.”
Unlike a simple contract or private writing, an Authentic Act does not require additional proof in court. If a dispute arises, the law presumes that the document is valid unless proven fraudulent.
Why is an Authentic Act Important?
The main advantage of an Authentic Act is that it provides strong legal protection. Courts in Louisiana automatically presume its validity, which means you don’t have to provide extra proof if someone challenges it.
Key Benefits of an Authentic Act:
✅ Stronger legal standing – Courts assume it’s valid.
✅ Less risk of disputes – Difficult to challenge in court.
✅ Prevents fraud – The notary ensures proper identity verification.
✅ Used in major transactions – Real estate, wills, successions, and contracts.
Without an Authentic Act, some legal transactions may be more vulnerable to disputes or even declared invalid.
When Do You Need an Authentic Act?
Not all legal documents require an Authentic Act, but for certain transactions, it’s either mandatory or highly recommended.
Situations Where an Authentic Act is Required or Recommended:
1. Real Estate Transactions
- Property sales and transfers must be executed as an Authentic Act to be legally valid.
- This ensures that ownership transfers are properly documented and not subject to later disputes.
- Mortgages and real estate donations also require notarization.
2. Wills & Successions
- A notarial will in Louisiana must be executed as an Authentic Act.
- This ensures the will is valid and enforceable after the person’s passing.
3. Durable Power of Attorney (Mandate)
- A General or Specific Mandate (Power of Attorney) must be in authentic form for certain transactions, such as selling property on behalf of someone else.
4. Contracts & Agreements
- Some legal agreements, such as marriage contracts, donations, and some business contracts, require an Authentic Act.
- This adds legal security and makes the contract harder to dispute.
5. Affidavits & Official Statements*
- In some cases, notarized statements or sworn affidavits need to be in the form of an Authentic Act to be considered legally binding.
How to Properly Execute an Authentic Act
Now that you know why an Authentic Act is important, let’s go over how to correctly execute one.
Step 1: Prepare the Document
- The document must clearly outline the agreement, transaction, or statement being made.
- It should include full names and addresses of the parties involved.
Step 2: Find a Louisiana Notary Public
- Unlike many other states, Louisiana notaries have broader powers and can draft documents without an attorney.
- Make sure the notary is commissioned and in good standing.
Step 3: Gather Two Competent Witnesses
- Witnesses must be over 18 years old and not related to the parties involved.
- Witnesses must sign the document in the notary’s presence.
Step 4: Verify Identity & Signatures
- The notary must confirm identities with valid ID.
- All parties, including witnesses and the notary, must sign in person.
Step 5: Notary Completes the Act
- The notary must sign and affix their official seal to complete the process.
- The document is now considered an Authentic Act under Louisiana law.
Common Mistakes to Avoid
Even a small mistake can invalidate an Authentic Act. Here are some common errors to watch out for:
🚫 Missing Witnesses – If there are fewer than two witnesses, the document is invalid.
🚫 Not Signing in the Presence of a Notary – All parties must sign at the same time in front of the notary.
🚫 Incorrect or Incomplete Information – Misspelled names, missing addresses, or unclear terms can cause legal problems.
🚫 Unqualified Witnesses – Witnesses cannot be related to the parties involved.
🚫 Failure to Include the Notary’s Seal – A notary’s official stamp and signature are required.
