Heirship may feel obvious within a family, but it still must be proved in court. Louisiana procedure allows a deceased person’s death, marriage, and the facts necessary to establish the relationship of heirs to be proved through official certificates or affidavits. It also permits jurisdictional facts, such as domicile and ownership of Louisiana property, to be shown by affidavit in appropriate cases. See Louisiana Code of Civil Procedure Article 2821.
“Heirs” technically inherit under Louisiana intestacy law. When a person leaves a will, the people who inherit under the will are called legatees. A succession may need to identify both heirs and legatees, depending on the circumstances.
What the Affidavit Procedure Requires
Affidavits used under Article 2821 must be executed by two people with knowledge of the facts and filed in the succession record. Louisiana does not require both affiants to be disinterested, but the proof should be competent, specific, and tied to the facts that matter. See Louisiana Code of Civil Procedure Article 2822.
In practice, heirship proof should identify the spouse, descendants, ascendants, or collateral relatives whose rights may be affected. It should also match relevant documents, such as:
- Death certificates
- Birth certificates
- Marriage records
- Divorce judgments
- Adoption judgments
- Acknowledgments of paternity
- Prior succession judgments
When filiation is disputed, the succession may require much more than family recollection. Louisiana law addresses formal acknowledgment in Civil Code Article 196, a child’s action to establish paternity in Article 197, and intestate inheritance in Article 880.
Article 197 is particularly important because an action to establish paternity for succession purposes after the alleged father’s death is subject to a one-year peremptive period.
When Affidavits Are Not Enough
Article 2823 allows the court to require additional evidence of any fact stated in an affidavit. A court is not required to accept incomplete or conclusory heirship allegations merely because they appear in a sworn document.
Once heirship becomes disputed in a contradictory proceeding, Louisiana draws a firm procedural line. Under Article 2824, a disputed fact cannot be proved solely through the affidavit procedure provided by Articles 2821 and 2822. Instead, the parties must introduce admissible evidence as in an ordinary proceeding.
Small succession affidavits have additional requirements involving signers, notice to nonsigning heirs, property descriptions, and inherited interests. Our guide to a small succession in Louisiana explains that separate procedure.
Why Heirship Proof Matters
Heirship problems frequently sit at the center of larger succession disputes. In Taboni, a claimant could not establish standing to enforce a promissory note held by the decedent because he had not proved that he was an heir through the documents or affidavit procedure contemplated by Louisiana law. See Taboni v. Estate of Longo, 803 So. 2d 55 (La. App. 4 Cir. 2001), reversed on other grounds, 810 So. 2d 1142 (La. 2002).
The burden of proof can also matter in forced-heirship litigation. In In re Succession of Ferguson, 114 So. 3d 1260 (La. App. 2 Cir. 2013), a forced-heir claimant was unsuccessful because the record did not establish that the affiants or executrix had reason to know of the claimed disability at the relevant time.
Field Law Can Help
An heirship issue that appears minor at the beginning can later control possession, administration, and title. Field Law can identify what evidence is sufficient, what documents are missing, and whether an uncontested proceeding may become succession litigation.
