TL;DR
Forced heirship in Louisiana protects descendants under 24 and permanently incapacitated descendants. They are entitled to a forced portion — 25% of the estate if one forced heir exists, 50% if two or more. The forced portion can be cut only on the narrow statutory grounds of disinherison listed in La. C.C. art. 1621.
Louisiana is the only state in the United States with forced heirship laws — a concept inherited from French and Spanish civil law that requires parents to leave a portion of their estate to certain children, regardless of what the will says.
What Is Forced Heirship?
Louisiana is the only state in the United States with forced heirship laws. This concept, inherited from French and Spanish civil law, requires a parent to leave a minimum portion of their estate — called the forced portion — to certain children, regardless of what the will says.
If a will attempts to disinherit a forced heir or leave them less than their forced portion, the forced heir can file a legal action to claim what they are owed. This is called a reduction action.
Who Qualifies as a Forced Heir?
Under Louisiana Civil Code Article 1493, a child qualifies as a forced heir if, at the time of the parent’s death, the child is:
- Under 24 years of age, or
- Permanently incapacitated — meaning unable to care for their person or administer their property due to mental incapacity or physical infirmity, regardless of age
A child who is 24 or older and not permanently incapacitated is not a forced heir. The parent may disinherit them or leave them nothing without legal consequence.
How Much Is the Forced Portion?
The size of the forced portion depends on how many forced heirs exist:
| Number of Forced Heirs | Forced Portion of Estate |
|---|---|
| One forced heir | One-quarter (25%) of the estate |
| Two or more forced heirs | One-half (50%) of the estate |
The remaining portion — called the disposable portion — can be left to anyone the testator chooses, including non-forced heirs, charities, or friends.
What Happens If a Will Violates Forced Heirship?
If a will leaves a forced heir less than their forced portion, the forced heir has the right to bring a reduction action within five years of the testator’s death (or two years from the date the forced heir learned of the will, whichever is shorter).
A reduction action asks the court to reduce the legacies of other beneficiaries to the extent necessary to satisfy the forced heir’s claim. The forced heir does not receive more than their forced portion — they simply cannot be left with less.
Can a Parent Disinherit a Forced Heir?
Yes, but only for specific legal causes. Louisiana Civil Code Article 1621 lists the exclusive grounds for disinherison:
- The child struck the parent or treated them cruelly
- The child was convicted of a crime punishable by death or life imprisonment
- The child used violence or fraud to prevent the parent from making a will
- The child accused the parent of a crime punishable by death or life imprisonment (unless the accusation was made as a victim)
- The child failed to communicate with the parent for two years without just cause (for children over 18)
- The child mistreated the parent’s surviving spouse
If none of these grounds exist, a disinherison clause in the will is invalid and the forced heir can claim their forced portion.
Forced Heirship and Louisiana Successions
Forced heirship analysis is a critical step in every Louisiana succession. (See: How to Open a Succession in Louisiana.) Before filing the Petition for Possession, an attorney must:
- Identify whether any forced heirs exist
- Determine whether the will (if any) satisfies the forced portion
- Calculate the forced portion based on the net value of the estate
- Address forced heirship in the Descriptive List and Judgment of Possession
Failing to address forced heirship in the succession documents can result in the Judgment of Possession being challenged after the fact — a costly and time-consuming problem.
Forced Heirship vs. Usufruct
Forced heirship is frequently confused with usufruct, but they are distinct concepts:
- Forced heirship concerns the rights of children against a parent’s will
- Usufruct concerns the rights of a surviving spouse to use and enjoy the deceased spouse’s half of community property (deeper dive: Usufruct and Naked Ownership in Louisiana)
Both concepts can apply simultaneously in the same succession, and both must be addressed in the Judgment of Possession.
Practical Implications for Estate Planning
If you have children under 24 or permanently incapacitated children, Louisiana forced heirship law significantly constrains your estate planning options. Key considerations include:
- You cannot leave your entire estate to your spouse if you have forced heirs
- Lifetime gifts made within three years of death may be subject to reduction if they impair the forced portion
- Trusts can be used to satisfy the forced portion while still controlling how and when assets are distributed
