What the rule says
Louisiana is the only US jurisdiction that recognizes forced heirship — a substantive limit on testamentary freedom that preserves a forced share for certain descendants. The framework derives from Louisiana's civil-law heritage and reflects French and Spanish legal traditions.
Under La. Civ. Code arts. 1493-1495:
Who are forced heirs
A forced heir is a descendant of the first degree (child of the decedent) who:
- Is under the age of 24 at the time of the decedent's death, OR - Is permanently incapable of taking care of themselves and managing their estate due to mental incapacity or physical infirmity, regardless of age
Grandchildren can be forced heirs by representation if their parent (the decedent's child) predeceased the decedent and would have qualified as a forced heir.
Not forced heirs: - Adult descendants over age 24 who are not incapacitated - Spouses (Louisiana's spousal protections come through other mechanisms — usufruct over community property and elective share rights, not through forced heirship) - Other relatives
What is the legitime
The legitime is the forced share that forced heirs must receive:
- One forced heir: The legitime is one-fourth of the estate. - Two or more forced heirs: The legitime is one-half of the estate, divided equally among forced heirs.
The legitime is computed on the "mass" of the estate, which includes: - All property of the decedent at death - Lifetime donations made by the decedent (with specific exclusions) - Less debts and certain other items
How the legitime is satisfied
If the testator's will gives the forced heir less than the legitime, the forced heir can claim the difference. The claim is satisfied:
1. From property given to other beneficiaries by the will (subject to specific Louisiana procedures) 2. From lifetime donations, in reverse order of donation date if needed 3. By reduction of excessive donations to satisfy the legitime
A forced heir can also be satisfied through usufruct (subject to specific Louisiana rules), giving the forced heir income/use of property without full ownership.
Just causes for disinheritance
La. Civ. Code art. 1621 provides limited grounds for disinheriting a forced heir. The grounds are exclusive — only specific listed reasons can support disinheritance:
- The forced heir attempted to take the parent's life - The forced heir was guilty of cruel treatment, crime, or grievous injury toward the parent - The forced heir attempted to prevent the parent from making a testament - The forced heir refused to ransom the parent or pay for the parent's release in specific circumstances - The forced heir struck or assaulted the parent - The forced heir failed to communicate with the parent for two years after attaining age 18, without just cause (subject to specific exceptions) - The forced heir was convicted of a capital crime, etc.
Grounds must be expressly stated in the testament with reasons. Disinheritance without proper grounds is invalid.
What this means in practice
Forced heirship produces several distinctive Louisiana outcomes:
- A Louisiana parent with three minor children cannot disinherit them through a will. The legitime guarantees the children together at least one-half of the estate. - A Louisiana parent with a permanently disabled adult child cannot disinherit that child. Even if the disabled child is age 50, they remain a forced heir. - A Louisiana parent with three adult non-disabled children CAN disinherit any or all of them. Adult non-disabled descendants are not forced heirs and have no claim to the estate against the testator's wishes. - Estate planning involves substantial legitime planning when minor or disabled descendants exist.
Coordination with community property
Forced heirship interacts with Louisiana's community property regime. The legitime is calculated on the decedent's estate (including the decedent's separate property and one-half of community property). Community property characterization can affect how the legitime is calculated and satisfied.
Coordination with usufruct
The surviving spouse's usufruct over community property (covered in la_intestacy_succession_descendants_spouse) can interact with forced heirship in complex ways. Forced heirs may receive their legitime in naked ownership, with the surviving spouse's usufruct continuing during the surviving spouse's life.
What you can do about it
For Louisiana residents engaged in estate planning:
- Identify forced heirs. Children under 24 or permanently disabled descendants of any age. - Plan to satisfy the legitime. Wills must provide for forced heirs adequately or face legitime claims. - Use lifetime donations strategically. Subject to forced heirship limits. - Consider trusts. Louisiana trust law allows forced heir interests to be held in trust under specific conditions. - Engage a Louisiana attorney. Forced heirship planning requires specialized expertise.
For non-Louisiana clients with potential Louisiana succession exposure (Louisiana real property, Louisiana domicile, etc.):
- Account for forced heirship. Even out-of-state planning may need to address Louisiana forced heirship if Louisiana property or domicile is involved. - Coordinate with Louisiana counsel.
Historical context and 1995/1996 reforms
Louisiana significantly narrowed forced heirship in 1995-1996. Before the reforms, all descendants were forced heirs regardless of age. The post-reform framework limits forced heirship to descendants under 24 or those permanently disabled.
The 1995-1996 reforms were among the most significant changes to Louisiana succession law in modern history. Estate planning advice from before the reforms is unreliable; current Louisiana practice reflects the post-reform framework.
Who this affects most
Louisiana forced heirship is most consequential for:
- Louisiana parents of minor children - Louisiana parents of adult children with permanent disabilities - Estate planners advising on Louisiana-specific limits on testamentary freedom - Out-of-state clients with Louisiana real property or domicile - Blended families where forced heirship preserves shares for children of prior relationships when those children meet forced heir criteria
Louisiana's forced heirship is the most distinctive feature of Louisiana succession law from a national perspective. No other US state imposes this kind of substantive limit on testamentary freedom. Effective Louisiana estate planning must account for forced heirship when forced heirs exist.
