Louisiana gives people substantial freedom to decide who will inherit their property. That freedom is not unlimited. Under Louisiana’s forced-heirship law, certain descendants are entitled to receive a minimum portion of a parent’s estate even when the parent’s will provides otherwise.
The rule does not protect every child, and it does not always require the parent to leave a forced heir 25% of the estate. Determining whether someone qualifies—and calculating what that person is entitled to receive—requires a closer examination of Louisiana law.
What Is Forced Heirship in Louisiana?
Forced heirship reserves part of a deceased person’s estate for descendants who meet Louisiana’s statutory definition of a forced heir.
The protected share is called the legitime. The portion reserved collectively for all forced heirs is called the forced portion. The remaining portion that the decedent may generally leave to other people is called the disposable portion.
If a parent leaves less than the required legitime to a forced heir, the will is not necessarily invalid. Instead, the forced heir may have the right to seek a reduction of excessive donations to restore the protected share.
Who Qualifies as a Forced Heir?
Under Louisiana Civil Code Article 1493, forced heirs generally include two categories of descendants.
Children Who Are Twenty-Three or Younger
A child of the decedent qualifies based on age if the child is twenty-three years of age or younger when the parent dies.
Article 1493 specifies that a person remains “twenty-three years of age or younger” until attaining the age of twenty-four. This category therefore includes minors and young adult children who have not yet reached their twenty-fourth birthday.
The child’s age when the will was signed does not control. The child’s age on the parent’s date of death generally determines whether the child qualifies.
Children Who Are Permanently Incapable of Caring for Themselves or Their Estates
A child of any age may qualify if, because of mental incapacity or physical infirmity, the child is permanently incapable of taking care of his or her person or administering his or her estate at the parent’s death.
Article 1493 also addresses an inherited, incurable disease or condition that, according to medical documentation, may render the descendant incapable of personal care or estate administration in the future.
Not every disability, diagnosis or medical limitation satisfies this standard. Whether an adult child qualifies can depend on medical documentation, functional abilities and the child’s condition at the legally relevant time.
A New 2026 Exception for Certain High-Net-Worth Disabled Forced Heirs
Effective August 1, 2026, Louisiana created a narrow exception affecting certain adult disabled forced heirs with extraordinary wealth.
Under Act 11 of the 2026 Regular Session, enacted as Louisiana Revised Statutes 9:2374, an adult who otherwise qualifies as a forced heir because of permanent incapacity and who has a direct or beneficial net worth exceeding $50 million has a forced portion of one dollar.
This highly specific exception will not affect most Louisiana families, but it is now part of the current forced-heirship analysis.
How Much Does a Forced Heir Receive?
The original version of this article said that a forced heir is always entitled to 25% of the estate. That is incomplete.
Under Civil Code Article 1495:
- If the decedent leaves one forced heir, the forced portion is generally one-fourth of the relevant estate.
- If the decedent leaves two or more forced heirs, the forced portion is generally one-half of the relevant estate.
When there are multiple forced heirs, the one-half forced portion is divided among them. Each forced heir does not receive one-half of the estate.
The calculation of an individual forced heir’s legitime is governed by Civil Code Article 1495.1. The result may also be limited when the calculated legitime would exceed what that heir would have received under intestate succession.
In addition, the calculation is not always based simply on the property physically remaining at death. Louisiana law establishes a calculation involving the net succession estate and certain lifetime donations. That is one reason forced-heirship disputes can require an examination of donations made before death as well as the will.
Are Grandchildren Forced Heirs?
Grandchildren are not automatically forced heirs merely because their parent died before the grandparent.
Representation for forced-heirship purposes occurs only under the specific rules in Article 1493. Depending on the circumstances, representation may apply when:
- The decedent’s predeceased child would have been twenty-three or younger at the decedent’s death; or
- A child of the predeceased descendant independently satisfies the applicable permanent-incapacity standard
The analysis may require looking at the ages, relationships and medical circumstances within that particular family line.

What Happens When a Will Leaves a Forced Heir Too Little?
A provision that infringes on a forced heir’s legitime is not automatically null.
Louisiana Civil Code Article 1503 provides that a donation impairing the legitime is reducible to the extent necessary to eliminate the infringement. In other words, the remedy generally addresses the shortfall rather than invalidating the entire estate plan.
A forced heir may need to assert the right through an action for reduction. The court may have to determine:
- Whether the claimant qualifies as a forced heir
- The value and composition of the calculation mass
- Which lifetime donations must be considered
- The amount of the forced and disposable portions
- What the forced heir received under the will or through other dispositions
- Which donations should be reduced
- Whether property should be returned or a monetary contribution made
These questions can turn an otherwise routine succession into contested litigation.
Can a Parent Disinherit a Forced Heir?
A parent cannot disinherit a forced heir merely because the relationship is difficult or because the parent prefers another beneficiary.
Louisiana recognizes specific statutory causes for disinherison. Civil Code Article 1621 includes causes involving certain violence, cruel treatment, serious criminal conduct, coercion intended to prevent the parent from making a will and an adult child’s unjustified failure to communicate with the parent for two years.
Louisiana requires more than simply omitting the forced heir’s name. The testament must identify the cause and state the facts or circumstances supporting the disinherison. A claimed disinherison may be challenged on grounds that:
- The alleged conduct did not occur
- The conduct does not match a statutory cause
- The testament does not state the necessary facts
- The conduct occurred after the disinheriting instrument was executed
- The child had just cause for the alleged failure to communicate
- The parent and child reconciled
Because the requirements are technical, someone considering disinherison should not rely on generic language. Read more about disinheriting immediate family members under Louisiana law.
Can the Legitime Be Placed in Trust?
Yes. Louisiana law permits a forced heir’s legitime to be placed in trust when the trust complies with the special rules governing a legitime in trust.
Under Louisiana Revised Statutes 9:1841, the trust generally must provide qualifying support from trust income, respect restrictions on conditions imposed upon the legitime and ultimately deliver the principal as the statute requires.
A trust may be useful when the forced heir:
- Is a minor
- Cannot independently manage property
- Has a disability
- Is financially vulnerable
- Receives means-tested government benefits
- Needs ongoing management and support
A trust intended to preserve eligibility for means-tested benefits requires specialized planning. Merely labeling a document a “special needs trust” does not ensure that it will accomplish that goal.
Our article on using a trust in a Louisiana estate plan discusses the broader benefits and limitations of trust planning.
Can You Leave Everything to Your Spouse?
Sometimes, but not always.
If no child or represented descendant qualifies as a forced heir, the testator may have greater freedom to leave property to a spouse. If a forced heir exists, leaving everything to the spouse in full ownership could infringe on the legitime.
Louisiana law offers planning options that may help support a spouse while respecting forced-heirship rights, including certain usufruct and trust arrangements. Community-property ownership and beneficiary designations also affect what the spouse receives.

Forced Heirship Depends on the Date of Death
Forced-heirship law has changed over time. The applicable law generally depends on the date the decedent died, not simply the date on which the testament was signed.
That distinction matters in older successions and when a will was prepared under a previous version of the law. It is possible for a will to have been drafted correctly when signed but require a different forced-heirship analysis when the testator later dies.
The estate plan should therefore be reviewed periodically, particularly when:
- A child approaches age twenty-four
- A child develops a serious disability
- A potential forced heir dies
- Grandchildren may qualify through representation
- The testator marries or divorces
- The testator makes substantial lifetime donations
- Louisiana changes its forced-heirship law
Field Law Can Help With Louisiana Forced-Heirship Planning
Forced heirship can affect wills, trusts, lifetime donations, surviving-spouse planning and contested successions. A small factual difference—such as a birthday, date of death, medical condition or predeceased child—may change the result.
Field Law helps Louisiana families determine whether a forced heir exists, calculate the protected share, structure a legitime in trust and address claims that a will or lifetime donation infringes on forced-heirship rights.
