Louisiana Affidavit of Heirship: Forms, Process & Cost

A Louisiana affidavit of heirship is a sworn statement — typically signed by two disinterested witnesses who knew the family — that identifies who the legal heirs of a deceased person are. It’s a useful tool for proving heirship without a full succession proceeding, but it doesn’t do everything. Knowing when to use it (and when you need something more) is the difference between a quick, cheap solution and a title problem that costs thousands to unwind later.

What is an affidavit of heirship in Louisiana?

An affidavit of heirship is a sworn document, signed under oath before a Louisiana notary, that declares who the heirs of a decedent are. It’s typically signed by two witnesses — people who knew the deceased and the family well enough to swear under penalty of perjury that they know who the heirs are — and are unrelated to the heirs themselves (“disinterested” witnesses).

The affidavit usually contains:

• The full legal name of the decedent
• Date and place of death
• Marital status at death (and details of any prior marriages)
• Names, addresses, and relationships of all heirs
• A statement that the decedent died with or without a will
• A list of children (including any predeceased children whose own children would inherit by representation)
• Sworn signatures of the witnesses
• Notarization

Louisiana’s statutory framework for the affidavit of heirship is found in La. R.S. 9:2821 (specifically for proving who inherits mineral rights and certain immovable property) and in the broader principle that sworn statements can serve as evidence of family relationships when no other public record exists.

Affidavit of heirship vs. small succession affidavit — what’s the difference?

These are commonly confused. They are not the same instrument.

In practice: if you want to prove the family tree (often years after the death, often for title curative work), use the affidavit of heirship. If you want to transfer property to the heirs now, use the small succession affidavit. See our complete guide to the Louisiana small succession affidavit.

When you need a Louisiana affidavit of heirship

The most common situations:

Older inherited real estate without clear title

Grandma died in 1985. No formal succession was ever opened. The property has been in the family ever since. Now someone wants to sell, mortgage, or develop it — and the title examiner says the chain of title is broken. An affidavit of heirship from two people who knew the family can re-establish who the heirs were, which becomes the foundation for clearing title.

Mineral rights and oil & gas leasing

This is the most frequent commercial use in Louisiana. When an oil & gas company wants to lease mineral rights from heirs of a long-deceased landowner, it needs to know who the heirs are. La. R.S. 9:2821 specifically contemplates the affidavit of heirship as evidence for mineral rights purposes. Most landmen and oil & gas attorneys will accept a properly-executed affidavit of heirship in lieu of a full succession for leasing purposes.

Bank accounts (in limited cases)

Some Louisiana banks will accept an affidavit of heirship in conjunction with other documentation for low-value accounts. Increasingly, however, banks prefer a small succession affidavit or a Judgment of Possession. Don’t assume a heirship affidavit alone will move bank funds — call the bank’s estate department first.

Affidavit of death, domicile, and heirship

A specific variation, sometimes called an “affidavit of death and heirship” or “affidavit of death, domicile, and heirship,” rolls multiple statements into one document: proof of death, proof of where the decedent was domiciled (which controls jurisdiction), and identification of heirs. This combined affidavit is the most common form requested by title companies and oil & gas leaseholders.

Who can sign an affidavit of heirship?

Two disinterested witnesses. “Disinterested” means they don’t stand to inherit anything from the decedent. They have to know the family well enough to swear under oath about who the heirs are — typically longtime friends, neighbors, in-laws, or distant relatives who themselves wouldn’t inherit.

The witnesses must:

• Be adults (18+) of sound mind
• Have actually known the decedent and the family
• Have personal knowledge of the marital history, children, and any predeceased descendants
• Not be heirs themselves (or spouses of heirs)
• Sign in front of a Louisiana notary

Finding two disinterested witnesses can be the hardest part of the process, especially for families where most adults are themselves heirs. Long-time family friends, neighbors, ministers, and longtime business associates are common signers.

Where to file a Louisiana affidavit of heirship

It depends on the purpose:

• For real estate: record in the conveyance records of the parish where the property is located. This creates a public record that future title examiners can rely on.
• For mineral rights: typically filed in the parish conveyance records and provided directly to the oil & gas company or landman.
• For bank accounts: provide directly to the bank’s estate department.
• For general family records: keep with the family papers; provide to any institution that asks.

Recording fees in Louisiana parishes typically run $50–$150 depending on the parish and the length of the document.

Cost of a Louisiana affidavit of heirship

Attorney fees for preparing an affidavit of heirship typically range from $500 to $1,200, depending on:

• Complexity of the family tree (multiple marriages, predeceased children, half-siblings, etc.)
• Whether genealogical research is needed
• Whether a combined “death, domicile, and heirship” affidavit is needed
• How many parishes the document must be recorded in
• Whether the witnesses are easily available or need significant coordination

Add roughly $100–$300 in third-party costs: notary fees, parish recording fees, certified death certificates if not already on hand.

Limitations of an affidavit of heirship

An affidavit of heirship is powerful but limited. Understand what it can’t do:

• It doesn’t transfer title. An affidavit of heirship is evidence of who the heirs are. It doesn’t move property out of the decedent’s name into theirs. For that, you need either a small succession affidavit or a Judgment of Possession from a full succession.
• It can be challenged. Because it’s based on witness testimony rather than a court finding, an affidavit can be challenged by anyone who claims to be a missed heir or who disputes the family tree. A Judgment of Possession has the force of res judicata; an affidavit doesn’t.
• Title insurance companies vary in acceptance. Some title insurers will write coverage over an affidavit of heirship; others require a formal succession. Check with the title company before relying on an affidavit alone for a major real estate transaction.
• It’s not a substitute for probate. If the decedent left a will that hasn’t been probated, the affidavit of heirship doesn’t replace the probate step.

Common mistakes to avoid

Using interested witnesses

If a witness is also an heir (or married to an heir), the affidavit is fatally defective. Title examiners and oil & gas attorneys catch this immediately. Use only disinterested witnesses.

Missing predeceased children

Louisiana’s representation rules (La. C.C. art. 881 et seq.) mean that children of a predeceased child inherit in their parent’s place. Forgetting to list a child who died young — or that child’s own children — creates a defective affidavit that can be challenged decades later.

Ignoring prior marriages

Children from prior marriages are often missed in family-prepared affidavits. Louisiana succession law treats them as heirs even if they were estranged or had no relationship with the decedent. A proper affidavit names them.

Assuming an affidavit replaces a succession

The most expensive mistake: relying on an affidavit alone to sell inherited property, when the title company later refuses to insure the buyer because the affidavit isn’t enough to clear title. Always check the title company’s requirements before relying on an affidavit for a real estate sale.

Frequently asked questions

How much does an affidavit of heirship cost in Louisiana?

Attorney fees typically range from $500 to $1,200. Add $100 to $300 for notary fees, parish recording, and certified death certificates. Most clients pay between $700 and $1,500 all-in.

What’s the difference between an affidavit of heirship and a small succession affidavit?

An affidavit of heirship proves who the heirs are — it’s signed by two disinterested witnesses and used as evidence in other proceedings. A small succession affidavit transfers property to the heirs — it’s signed by the heirs themselves and presented to banks, the OMV, and the parish recorder to effectuate the transfer. See our guide to the Louisiana small succession affidavit.

Who can sign an affidavit of heirship?

Two disinterested witnesses — adults (18+) who knew the decedent and family well, are not heirs themselves, and are not married to an heir. Common signers include longtime friends, neighbors, in-laws, ministers, or business associates.

Where do I file an affidavit of heirship in Louisiana?

If it concerns real estate, record it in the parish conveyance records where the property is located. For bank or financial accounts, provide it directly to the institution. For mineral rights, file in parish conveyance records and provide a copy to the leasing company.

Is an affidavit of heirship enough to sell inherited property in Louisiana?

Sometimes — but always check with the title insurance company first. Some title insurers will write coverage over an affidavit of heirship; others require a full succession and Judgment of Possession. For high-value transactions, a Judgment of Possession is the safer route.

Can I download a Louisiana affidavit of heirship form?

There’s no single official statewide form. The document must be drafted to fit the specific decedent and family situation — generic templates frequently miss Louisiana-specific requirements (representation, prior-marriage children, community property considerations) and get rejected by title examiners or oil & gas attorneys. Send us your situation and we’ll prepare the affidavit correctly.

How long does it take to prepare an affidavit of heirship?

From engagement to fully-executed document, typically 1–2 weeks. Faster if the family tree is simple and the witnesses are easily available; slower if genealogical research is needed or witnesses are hard to coordinate.

Can an affidavit of heirship be used for mineral rights leasing?

Yes — this is one of the most common uses in Louisiana. La. R.S. 9:2821 specifically contemplates the affidavit as evidence of heirship for mineral rights purposes. Most landmen and oil & gas attorneys accept properly-executed affidavits for leasing.

How long is an affidavit of heirship valid?

An affidavit of heirship doesn’t “expire” in the traditional sense. Once recorded, it remains part of the public record. However, if circumstances change (a previously-unknown heir surfaces, for example), the affidavit may need to be amended or supplemented.

What if a key witness has died or moved away?

You need two living, available witnesses. If the original witnesses are gone, identify others who knew the family. If no one is left who has personal knowledge of the family tree, you may need to combine the affidavit with genealogical records, baptismal certificates, or older family documents — or proceed with a formal succession instead.
