Forced Heirship Louisiana: Who Qualifies and What They're Owed

Louisiana is the only state in the country that restricts a parent's ability to disinherit their children. Every other state allows a testator to leave their estate to anyone they choose, cutting out children entirely if they wish. In Louisiana, that's not legal for certain children — and a will that tries to do it can be challenged in court.

This is forced heirship, rooted in Louisiana's French and Spanish civil law tradition. If you're settling a Louisiana estate and there are children involved — regardless of what the will says — you need to understand whether forced heirship applies.

Who Is a Forced Heir?

Under Louisiana Civil Code Article 1493, a forced heir is a child of the decedent who meets at least one of two criteria at the exact moment of the parent's death:

Criterion 1 — Age: The child has not yet reached their 24th birthday. A child who is 23 years and 364 days old at the time of the parent's death is a forced heir. A child who turned 24 the day before the parent died is not.

Criterion 2 — Permanent incapacity: The child is of any age but suffers from a mental incapacity or physical infirmity that renders them permanently unable to care for themselves or manage their own affairs. This includes children with inherited, incurable diseases or conditions that may cause future incapacity, even if they are currently asymptomatic.

Note that only descendants of the first degree (the decedent's own children) are automatically considered forced heirs. Grandchildren can qualify through the doctrine of representation — but only if the grandchild personally meets the age or incapacity criteria, OR if their predeceased parent (the decedent's child) would have been 23 or younger at the time of the grandparent's death.

What Is the Forced Heir's Guaranteed Share?

The legally protected portion is called the legitime (sometimes spelled "légitime"). It's calculated based on the total number of forced heirs:

The legitime applies to the entire estate — both separate property and the decedent's share of community property. The remaining portion (called the disposable portion) can be freely given to anyone the testator chooses: other children, a spouse, a charity, or a stranger.

There is one exception: if the standard forced fraction is greater than what the forced heir would have received under pure intestacy, the legitime is reduced to the intestate share. In practice this mainly matters in large families.

What Happens When a Will Tries to Violate Forced Heirship?

A will that attempts to leave a forced heir less than their legitime is not automatically void. Instead, the forced heir has the right to bring a legal action called a reduction — a court proceeding that challenges the will's distributions and forces a recalculation to restore the forced heir's entitled share.

The forced heir must affirmatively assert this right. If they don't bring the action within the applicable prescriptive period, they may lose the ability to claim the legitime. This is why any estate involving children under 24 or potentially incapacitated children — even if the will appears to have excluded them — requires careful legal review.

What Grounds Exist to Disinherit a Child?

Louisiana does allow a parent to disinherit a forced heir, but only for specific, enumerated causes listed in the Civil Code. These include:

• The child struck or physically mistreated the parent
• The child failed to communicate with or visit the parent for two years without just cause
• The child was convicted of a crime carrying a sentence of death or hard labor
• The child accused the parent of committing a crime carrying a capital sentence, unless the accusation was made in self-defense

The grounds for disinheritance must be stated expressly in the will. If the will is silent on the reason, or if the stated reason doesn't match one of the enumerated causes, the forced heir can challenge the disinheritance and recover their legitime.

Forced Heirship and the Surviving Spouse

Forced heirship and the surviving spouse's usufruct interact in ways that can create genuine family tension.

When a parent dies intestate and is survived by both a spouse and children, the surviving spouse acquires a usufruct (right of use) over the decedent's half of community property, while the children receive naked ownership of that same property. The children cannot force the sale of the property without the spouse's consent during the usufruct period, and the usufruct only terminates upon the spouse's death or remarriage.

When the parent dies testate (with a will) and there are forced heirs, the testator may have tried to give the spouse more than the disposable portion allows. If doing so reduces a forced heir's legitime below the statutory minimum, the will is vulnerable to a reduction action.

Blended families — where the surviving spouse has stepchildren from the decedent's prior relationship — are the most common source of forced heirship disputes.

Practical Implications for Estate Settlement

If there are children under 24: Before distributing any assets, identify whether any forced heirs exist and calculate the legitime. Distributing to others first can expose the succession representative to personal liability if a forced heir later asserts their claim.

If a child claims permanent incapacity: The burden is on the child to demonstrate that the incapacity meets the Civil Code's standard. Medical documentation, physician statements, and in some cases expert testimony may be required. This is contested territory that virtually always requires attorney involvement.

If the estate is small: Even small estates are subject to forced heirship. The dollar thresholds for the Small Succession Affidavit ($125,000 or $200,000) are about estate size for procedure purposes — they don't exempt the estate from forced heirship obligations.

Forced heirship is one of the most legally complex aspects of settling a Louisiana estate, especially in blended families.
