Louisiana Adult Adoption: How It Works and Who Qualifies

Adult adoption in Louisiana comes up in situations that have nothing to do with child welfare. A stepparent who raised a child from infancy but never formalized the relationship. A long-term caregiver who wants to establish legal family ties before a health crisis. An adult who was raised by grandparents and wants that bond recognized by law for inheritance purposes. In all of these cases, Louisiana law provides a pathway — and it is more streamlined than most people expect.

Under Louisiana Civil Code Article 212, any person who has reached the age of majority may be adopted by another adult. The process bypasses most of the requirements that govern the adoption of minors: there is no home study, no termination of the biological parents' rights, and no post-placement supervision period. It is fundamentally a civil law contract between two consenting adults, ratified by a court.

Who Can Adopt an Adult in Louisiana

Louisiana law does not impose strict restrictions on who may petition to adopt an adult, as long as both parties are adults and both consent. The adopting person must be of legal age (18 or older in Louisiana). Unlike adoption of minors, the adopting party does not need to be significantly older than the person being adopted, though courts may consider the relationship's nature as part of the "best interest of the parties" analysis.

There is one notable exception to the normal process: if the adopting person is the spouse or surviving spouse of the adult adoptee's parent, no court approval is required. In that scenario, the adoption can be completed without a petition, which simplifies the process significantly for stepparent situations where the adoptee is already an adult.

For all other cases, a formal court petition is required.

The Adult Adoption Process in Louisiana

Step 1: File a petition in District Court. Adult adoptions in Louisiana are handled by District Courts rather than juvenile courts. The petition must be filed in the parish where either the adopting person or the adoptee is domiciled. The petition identifies both parties, states their relationship, and affirms their mutual consent to the adoption.

Step 2: Consent of both parties. Both the adopting adult and the adult being adopted must consent to the adoption. This is the central requirement. There is no requirement to obtain consent from the adoptee's biological parents because adult adoption does not terminate biological parental rights — it creates an additional legal parent-child relationship.

Step 3: Court hearing. The court schedules a hearing to confirm that both parties understand the legal consequences of the adoption and that the adoption serves the best interest of both parties. These hearings are typically brief and uncontested in straightforward cases.

Step 4: Judgment of adoption. Once the judge signs the judgment, the adoption is legally complete. The adoptee takes the right to use the adopting party's surname if they choose, and the legal relationship of parent and child is established for all purposes including inheritance.

What Adult Adoption Does — and Doesn't Do

What it creates:

• A legal parent-child relationship between two adults
• Inheritance rights: the adoptee becomes a legal heir of the adopting party's estate under Louisiana succession law
• The right to use the adoptive parent's surname
• All other legal benefits of the parent-child relationship, including the ability to be listed as a dependent on insurance if applicable

What it does not do:

• Terminate the adoptee's legal relationship with their biological parents (unlike adoption of a minor, which severs those ties)
• Require a home study or post-placement supervision
• Require proof of unfitness of any biological parent
• Automatically change the adoptee's original birth certificate (an amended birth certificate can be requested following the judgment)

The fact that biological relationships are not severed distinguishes adult adoption from minor adoption in a meaningful way. An adult adoptee retains inheritance rights from their biological family while also gaining inheritance rights from their adoptive parent. Louisiana's forced heirship laws, which protect inheritance rights for certain heirs, may be relevant depending on the estate planning context — something worth discussing with an estate attorney alongside the adoption process.

Why Louisiana Families Pursue Adult Adoption

Formalizing a stepparent relationship. Many families in Louisiana have stepparents who raised children from early ages without ever completing the adoption while the child was a minor — often because the biological parent's rights were never terminated or consent was not available. Once the child reaches adulthood and consents, the adoption can proceed without any of those earlier obstacles.

Establishing legal authority for medical and financial decisions. When a caregiver who raised a child reaches a point of age or illness, or when the adult "child" needs a recognized next-of-kin for medical decisions, adult adoption creates the legal framework that an informal relationship lacks.

Inheritance and estate planning. Louisiana's succession law requires formal legal relationships for inheritance rights in intestate estates. Adult adoption is sometimes used alongside estate planning to ensure that a person who has been treated as a family member for decades is legally recognized as such.

Kinship situations following informal care. In Louisiana, informal kinship care arrangements — where grandparents, aunts, uncles, or others raise children without formal legal proceedings — are common. When those children reach adulthood, adult adoption provides a straightforward mechanism to formalize the relationship.

Costs and Timeline

Because adult adoption does not require a home study, agency fees, or an extended post-placement period, the costs are significantly lower than adoption of a minor. Primary costs are attorney fees for drafting and filing the petition and court filing fees, which vary by parish. In uncontested cases, the process can be completed in a matter of weeks rather than the months or years a child adoption requires.

If the situation involves the spouse or surviving spouse of the adoptee's parent, no court petition is required at all, which reduces cost and time further.

Working With an Attorney

While Louisiana's adult adoption process is more accessible than adoption of a minor, working with an attorney who understands the Louisiana Children's Code and Civil Code is still advisable. The attorney ensures the petition is filed correctly, that the consent documentation meets court standards, and that the inheritance implications are clearly understood before the judgment is entered. Given the relatively low attorney time required for a straightforward adult adoption, this is one situation where legal representation is both practical and affordable.
