Definition
Forced heirs are persons whom a testator or donor is legally prohibited from disinheriting below a minimum share of the estate reserved for them by law. The concept originates in civil law traditions — specifically the Louisiana Civil Code — and operates as a limitation on testamentary freedom: regardless of what a will provides, forced heirs retain a legally protected portion of the decedent's estate. That protected portion is called the legitime (or forced portion). Only in cases where the law recognizes just cause for disinheritance may a testator lawfully exclude a forced heir.
In Louisiana, forced heirship is a constitutional and statutory right. Forced heirs historically included all descendants; modern Louisiana law has narrowed the class significantly, generally limiting forced heir status to descendants who are twenty-three years of age or younger, or descendants of any age who are permanently incapacitated from caring for themselves.
Common Language
Wiktionary: Plural of forced heir.
No substantive common-language definition exists independent of the legal term. "Forced" in ordinary English suggests coercion; in this legal context it does not mean a person is compelled to inherit, but rather that the testator is compelled to preserve a share for them. The heir's right is the operative force — not any compulsion on the heir.
Common Confusion
Forced heirs are sometimes conflated with intestate heirs or pretermitted heirs. These are distinct categories. Intestate heirs inherit because there is no valid will; forced heirs inherit a protected portion even when a valid will exists. Pretermitted heirs are those inadvertently omitted from a will — a common law concept with different remedial mechanics than forced heirship. Forced heirship is also distinct from elective share statutes in common law states, which protect surviving spouses but not descendants. Researchers should not assume that elective share doctrine and forced heirship are interchangeable: they rest on different legal traditions, protect different classes of persons, and apply different calculations.
Recognized Forms
/SUBTYPES
The forced portion (legitime): The fixed share of the estate that cannot be devised away. In Louisiana, this portion is calculated based on the number of forced heirs and the nature of the estate.
Disinheritance for just cause: Louisiana law enumerates specific grounds on which a testator may lawfully disinherit a forced heir — such as a child striking a parent, or cruel treatment. Outside these enumerated grounds, disinheritance is ineffective as to the forced portion.
Why It Matters in Research
Forced heirship is almost entirely a Louisiana phenomenon within American law, rooted in the state's French and Spanish civil law heritage. Researchers working in any other U.S. jurisdiction will not encounter forced heirs as a live doctrine — but they will encounter the concept when tracing Louisiana succession disputes, reviewing multi-state estate plans involving Louisiana property, or reading comparative law materials.
The doctrine has changed substantially over time, and this is the critical research trap. The historical Louisiana Civil Code applied forced heirship broadly to all legitimate descendants; post-1995 constitutional amendments and statutory revisions dramatically narrowed the protected class. A researcher reading older Louisiana cases, treatises, or the historical dictionary entries here will encounter forced heirship rules that no longer reflect current law. The Civil Code article cited in both Black's editions — article 1495 — has been amended and renumbered; any research path beginning with that citation must be updated against current Louisiana Revised Statutes and the Louisiana Constitution, Article XII, Section 5.
For estate planning documents drafted before the 1995 reforms, researchers should be alert to provisions structured around old forced heirship calculations. Wills and trust instruments from that era may have been deliberately or inadvertently shaped by rules that no longer apply to the same class of persons.
The corpus connection to intestacy and escheat is real but indirect: forced heirship prevents certain transfers away from descendants, while escheat operates when no heirs exist at all. These doctrines occupy opposite ends of the succession problem.
Historical Dictionary Support
Both Black's editions define forced heirs identically in substance: persons whom the testator or donor cannot deprive of the reserved portion except for just cause, citing Civil Code La. art. 1495. The second edition adds three Texas cases — Crain v. Crain, Hagerty v. Hagerty, and Miller v. Miller — suggesting that Texas courts were also grappling with the concept, likely in the context of community property and civil law inheritance disputes affecting property straddling the Louisiana-Texas border or involving Louisiana-origin law.
What the historical dictionaries do not capture is the volatility of the doctrine. Both entries reflect a pre-reform understanding in which the class of forced heirs was far broader than it is today. Neither flags any limitation by age or capacity. Researchers relying solely on these entries for a current understanding of Louisiana forced heirship would significantly overstate the protected class. The entries are accurate to their period but should be treated as historical baselines, not current doctrine.
Jurisdictional Note
Forced heirship in its classical form is operative only in Louisiana among U.S. jurisdictions. Common law states protect surviving spouses through elective share statutes but generally impose no forced share for descendants. Internationally, forced heirship or legitime-equivalent rules are standard in civil law countries across continental Europe and Latin America, making the concept central to international succession and conflict-of-laws research.
