Inheritance Rights of Unborn and Posthumously Born Children in Louisiana

Louisiana succession law addresses one of the more poignant questions that can arise after a death: what happens to a child who was not yet born when their parent died? The answer depends on whether the child was conceived before or after the parent’s death, and in some cases, on specific written authorizations the parent left behind.

Children Conceived Before Death and Born After Death

Louisiana Civil Code Article 940 provides a clear rule for the most common situation: a child conceived before a parent’s death but born after the parent dies.

Such a child is treated as having existed at the time of the parent’s death and has the same inheritance rights as any other child born during the parent’s lifetime. The fact that the child had not yet been born at the moment of the parent’s death does not affect their legal rights.

This means the posthumously born child:

• Has full rights as a forced heir (if they qualify by age or disability)
• Inherits equally with other children in an intestate succession
• Can receive a legacy under a will on the same terms as other children

Children Conceived After a Parent’s Death

More unusual — but increasingly relevant with advances in reproductive medicine — is the situation where a child is conceived using the gametes (sperm or eggs) of a person who has already died.

Louisiana law provides limited inheritance rights for children conceived posthumously when both of the following conditions are met:

1. The deceased parent left written authorization for their surviving spouse to use their gametes after their death.
2. The child is born to the surviving spouse within three years of the deceased parent’s death.

If both conditions are satisfied, the posthumously conceived child may inherit property from the deceased parent. If either condition is not met, the child does not have inheritance rights from that parent under Louisiana succession law.

Practical Implications

For families navigating succession after a death where a pregnancy is involved — or where reproductive medicine decisions were made before death — the succession timeline matters. A succession cannot be fully closed while inheritance rights of an unborn or unconceived child remain unresolved.

The succession representative has a duty to account for all potential heirs. If a posthumously born child is expected, the court may need to defer final distribution until the child is born and their rights are confirmed.

Estate Planning Considerations

If you have concerns about inheritance rights for future children — whether through natural birth or assisted reproductive technology — estate planning documents can address these situations explicitly. A well-drafted will can specify your intent about posthumously conceived children and ensure your estate plan reflects your wishes.

Consult an Attorney Before the Succession Closes

If a pregnancy is involved in a Louisiana succession — whether the child was conceived before or after the parent’s death — the succession cannot and should not be finalized until the child’s inheritance rights are fully addressed.
