Forced heirship is the Louisiana legal doctrine that protects certain children from being disinherited by their parents. Under La. C.C. art. 1493, a deceased parent must leave a minimum share of their estate — called the forced portion or légitime — to qualifying children, regardless of what the will says. Louisiana is the only state in the United States that still has forced heirship as part of its core succession law.

The quick answer: who is a forced heir in Louisiana?
A child of a Louisiana decedent qualifies as a forced heir if — at the time of the parent’s death — the child is:
- Under the age of 24, OR
- Of any age and permanently incapable of taking care of themselves or administering their estate due to mental incapacity or physical infirmity (La. C.C. art. 1493(A))
If neither condition applies — the child is 24 or older and capable — the parent has full freedom to leave that child out of the will. The child is not a forced heir and forced heirship doesn’t protect them.
Forced heirship can also extend, in limited circumstances, to grandchildren by representation — specifically when the parent (the decedent’s own child) has predeceased the decedent and the grandchild is under 24 or permanently incapacitated. The grandchild then steps into the parent’s shoes as a forced heir.
Where forced heirship comes from
Forced heirship traces back to Louisiana’s Civil Code roots in French and Spanish law — one of the few civil-law features that survived the state’s incorporation into the United States. For most of Louisiana’s history, ALL children of any age were forced heirs, regardless of capacity. A parent could not disinherit any child without statutory cause.
The current limited form of forced heirship dates to the 1990s. In 1995, Louisiana voters approved Constitutional Amendment 4 (codified as La. C.C. art. 1493), narrowing forced heirship to children under 24 or permanently incapacitated. Earlier rules continue to apply to deaths before that effective date, which is mostly historical now.
Louisiana’s forced heirship is distinct from anything in common-law states. Most states allow complete testamentary freedom — a parent can disinherit any adult child for any reason. Louisiana does not.
The forced portion (légitime) — how much must go to forced heirs?
The forced portion, also called the légitime, is the minimum share of the estate that must pass to forced heirs. The remaining share — called the disposable portion — is what the parent can freely will to anyone they choose.
The size of the forced portion depends on how many forced heirs there are:
| Number of forced heirs | Forced portion (légitime) | Disposable portion |
|---|---|---|
| 1 forced heir | 1/4 of the estate | 3/4 of the estate |
| 2 or more forced heirs | 1/2 of the estate | 1/2 of the estate |
The forced portion is divided equally among all forced heirs. So if there are 3 forced heirs, each receives 1/6 of the estate (1/2 ÷ 3). If there are 4 forced heirs, each receives 1/8 (1/2 ÷ 4). And so on.
The remaining disposable portion can be given to the surviving spouse, non-forced-heir children, charities, friends, or whoever the testator chooses.
Calculating the légitime — the “notional mass”
The forced portion is calculated on the notional mass of the estate, not just whatever’s left at death. The notional mass includes:
- All assets at death (the “active mass”)
- Minus debts and certain administration expenses
- Plus certain gifts the decedent made during life (called collation for gifts to descendants)
This means a parent cannot simply gift away assets during life to reduce the forced portion — certain lifetime gifts are pulled back into the calculation. The rules around collation are intricate and depend on whether the gift was expressly “extra portion” and other factors.
What happens if a will violates forced heirship?
If a will leaves a forced heir less than their légitime — either by giving them nothing or by giving them less than their statutory share — the will is not entirely invalid. Instead, the disposition is reduced by the court to satisfy the forced portion.
This is called a reduction action (La. C.C. arts. 1503–1518). The forced heir (or someone acting on their behalf) files an action with the succession court asking the court to claw back enough property from the over-favored beneficiaries to restore the forced portion. The court then re-allocates.
If the forced heir doesn’t bring a reduction action within the legal time limit (generally 5 years from the time of opening the succession), the right to claim the légitime is lost.
How a parent CAN legitimately disinherit a forced heir
Despite forced heirship’s protective intent, Louisiana law does allow a parent to disinherit a forced heir on specific narrow grounds (La. C.C. art. 1621). The grounds include:
- The child has raised a hand to strike the parent, OR has actually struck the parent
- The child has been guilty of cruel treatment, crime, or grievous injury toward the parent
- The child has attempted to take the parent’s life
- The child, without reasonable basis, accused the parent of a crime punishable by life imprisonment or death
- The child used physical violence or has been convicted of a crime of violence against the parent
- The child has been a usual or notorious user of illegal substances and has refused parental help
- The child has refused communication with the parent for two years without cause (where they had means to do so)
- The child marries a person against the parent’s consent, when the child was a minor
- Other specific grounds in the statute
These grounds are narrow, specific, and difficult to prove. The cause must be expressly stated in the will (you can’t just imply it), the proof must be admissible, and the burden falls on the person trying to enforce the disinheritance. See our complete guide on when a parent can disinherit a forced heir in Louisiana for the full legal analysis.
How to plan around forced heirship (legitimately)
For parents who want to minimize the impact of forced heirship without crossing into illegal disinheritance, several planning techniques can help — some more effective than others:
Wait until all children are 24+
The simplest technique — if available — is to wait until all children are over 24 and capable. At that point, forced heirship no longer protects them, and full testamentary freedom returns. Many estate plans are restructured at this milestone.
Use trusts strategically
Property held in certain types of trusts can be structured to satisfy the légitime requirement while still controlling timing and conditions of distribution. The forced heir’s interest must be vested (not contingent), but the trust can defer actual distribution until specific events (graduation, age 30, etc.).
Use the disposable portion thoughtfully
The disposable portion (1/2 or 3/4 depending on number of forced heirs) can go to a surviving spouse, charities, or other beneficiaries. Properly drafted, this can substantially shift the practical distribution while still respecting forced heirship.
Lifetime gifts to non-forced-heir beneficiaries
Gifts during life to non-forced heirs (such as a spouse, friends, charities) reduce the estate value at death — but watch out for the collation rules that can pull lifetime gifts to descendants back into the calculation.
Usufruct strategies for surviving spouses
Louisiana law lets a parent grant the surviving spouse a usufruct over the property left to forced heir children. The forced heirs technically receive their share (the naked ownership), but the surviving spouse uses the property for life. This is one of the most common Louisiana planning techniques.
What does NOT work
- Just omitting the child from the will. Silence doesn’t disinherit. A forced heir not named in the will still gets the légitime.
- Saying “I don’t want them to inherit anything” without legal cause. A disinheritance clause without a valid statutory ground is unenforceable.
- Transferring everything to a trust that excludes the forced heir. If the trust property would have been in the estate, it’s subject to forced heirship analysis.
- Out-of-state moves at the last minute. Louisiana law applies to the succession of a Louisiana decedent regardless of where they died, particularly for Louisiana real estate.
When did forced heirship end (or change) in Louisiana?
Forced heirship did NOT end. Louisiana voters approved Constitutional Amendment 4 in 1995, which substantially narrowed forced heirship from “all children of any age” to “children under 24 or permanently incapacitated.”
The amendment took effect on January 1, 1996. Successions of decedents dying before that date are governed by the old, broader rule. Successions of decedents dying on or after that date are governed by the current narrower rule.
The current rules remain in force in 2026. There have been periodic legislative proposals to further narrow or eliminate forced heirship, but none have succeeded in recent years.
Forced heirship and other Louisiana estate planning concepts
Forced heirship vs. intestate succession
Forced heirship is the rule that applies when there is a will. Intestate succession is the rule that applies when there is no will. They’re separate systems, though they share some underlying concepts about who counts as an heir.
Forced heirship vs. community property
Forced heirship operates on the separate property of the deceased parent plus their half of community property. Community property itself follows different rules — the surviving spouse owns their half independently and the deceased spouse’s half passes through succession.
Forced heirship vs. usufruct
A usufruct is the right to use property for a period. Louisiana law commonly grants the surviving spouse a usufruct over property the deceased spouse left to forced heir children. The forced heirs receive their portion (the naked ownership), but the surviving spouse uses the property until death or remarriage.
Forced heirship vs. trusts
A revocable living trust holding what would be the légitime is generally subject to forced heirship analysis as if the property were still in the estate. Trusts can satisfy the légitime requirement through proper structuring, but cannot circumvent forced heirship.
Special situations
Adopted children
Adopted children have the same forced heirship rights as biological children for purposes of inheriting from their adoptive parents. They generally do not retain forced heirship rights to inherit from their biological parents (with limited exceptions for stepparent adoption).
Children born outside marriage
Children born outside of marriage have forced heirship rights to their natural parent’s estate if filiation has been legally established (through acknowledgment, judicial determination, or other means). See our guide on the rights of children born outside of marriage in Louisiana successions.
Stepchildren
Stepchildren are NOT forced heirs of a stepparent, regardless of how long the relationship existed. Forced heirship requires legal parentage, not just a parental relationship. See our guide on the inheritance rights of illegitimate children for related issues.
The permanent incapacity exception — what counts?
The exception for adult children with “permanent incapacity” is taken seriously. It generally requires the inability to manage one’s own affairs (financial, legal, daily living) due to mental or physical condition, expected to be permanent. Routine adult dependency, mental health treatment, or addiction generally don’t qualify. Medical and legal evaluation matters.
Frequently asked questions
What is forced heirship in Louisiana?
Forced heirship is the doctrine requiring a Louisiana decedent to leave a minimum share (the “forced portion” or légitime) of their estate to qualifying children — children under 24 at the parent’s death, or children of any age permanently incapacitated. Louisiana is the only state with forced heirship as part of its core succession law.
Who is a forced heir in Louisiana?
A child of the decedent who is under 24 at the parent’s death, OR a child of any age who is permanently incapable of taking care of themselves or administering their estate due to mental or physical condition. Grandchildren can also qualify by representation if their parent (the decedent’s child) predeceased the decedent and the grandchild meets either condition.
How much does a forced heir inherit?
If there is one forced heir, they receive 1/4 of the estate (1/4 légitime). If there are two or more forced heirs, they collectively receive 1/2 of the estate (divided equally among them). The remaining 3/4 or 1/2 is the disposable portion the decedent can freely give to anyone.
Can I disinherit a child in Louisiana?
If the child is 24 or older and capable of managing their affairs, yes — they’re not a forced heir and you can disinherit them freely. If the child is under 24 or permanently incapacitated, you can only disinherit them on specific narrow statutory grounds (La. C.C. art. 1621) such as actually striking the parent, attempting their life, or refusing communication for 2+ years. The grounds are difficult to prove. See our complete guide on disinheriting a forced heir in Louisiana.
When did forced heirship end in Louisiana?
Forced heirship did NOT end — it was narrowed. Constitutional Amendment 4, effective January 1, 1996, limited forced heirship to children under 24 or permanently incapacitated. Before that, all children were forced heirs regardless of age. The current narrower rule remains in effect in 2026.
How is the forced portion calculated?
The forced portion is calculated on the “notional mass” of the estate: all assets at death, minus debts and certain expenses, plus certain lifetime gifts subject to collation. The result is multiplied by 1/4 (one forced heir) or 1/2 (two or more) to determine the protected share.
What happens if a Louisiana will violates forced heirship?
The will isn’t invalid — instead, the over-favored dispositions are reduced by court order through a “reduction action” (La. C.C. arts. 1503–1518). The court redistributes property from the over-favored beneficiaries to satisfy the forced portion.
How long does a forced heir have to claim their légitime?
Generally five years from the opening of the succession to file a reduction action. After that, the right to claim is lost.
Does forced heirship apply to property in a trust?
Yes, generally. Property held in a revocable living trust is treated for forced heirship purposes as if it were still in the decedent’s estate. Trusts can satisfy the légitime requirement but cannot circumvent it.
Can a forced heir waive their forced heirship rights?
A forced heir can renounce their right to claim the légitime after the parent dies. They cannot prospectively waive the right while the parent is still alive (with very limited exceptions).
How do I plan around forced heirship without disinheritance?
Common strategies include: (a) waiting until all children turn 24 to make final estate decisions, (b) using usufruct for the surviving spouse over property left to forced heirs, (c) carefully using the disposable portion (1/2 or 3/4) for non-forced-heir beneficiaries, (d) gifts during life to non-descendant beneficiaries, (e) using certain trust structures. Each requires Louisiana-specific drafting.
Forced heirship is one of the most distinctively-Louisiana parts of estate law — and one where mistakes are expensive to fix after the fact.
