Adult adoption in Louisiana runs on Civil Code Article 212, which sets up two separate tracks: a stepparent can complete the adoption before a notary with no judge involved, while every other adult adoption requires a joint petition and a court hearing.1Louisiana State Legislature. Louisiana Civil Code Art 212 – Adult Adoption Requirements Which track you’re on decides how long the process takes, what you file, and whether you ever see a courtroom. One rule cuts across both tracks and voids the adoption if missed: the spouses of both parties have to sign.
The Two Tracks
If the person adopting is the spouse or surviving spouse of one of the adoptee’s parents, the adoption can be done by authentic act before a notary. No judicial authorization is required.1Louisiana State Legislature. Louisiana Civil Code Art 212 – Adult Adoption Requirements This is the stepparent path, and it can be wrapped up quickly.
Every other adult adoption takes the court path. The adopter and adoptee file a joint petition, and a judge holds a hearing to decide whether the adoption is in the best interest of both parties before authorizing it.1Louisiana State Legislature. Louisiana Civil Code Art 212 – Adult Adoption Requirements The petition is filed in the district court of the parish where either the adopter or the adoptee is domiciled.2Justia Law. Louisiana Code of Civil Procedure Article 74.5 – Adult Adoption
Louisiana does not require a minimum age difference between adopter and adoptee on either track.
Spousal Consent and Personal Appearance
Under Civil Code Article 213, the spouses of both the adopter and the adoptee must sign the act of adoption to concur. If a spouse refuses or is simply left off, the adoption is absolutely null and treated as if it never happened.3Justia Law. Louisiana Civil Code Art 213 – Adult Adoption Form Signing does not make the spouse a parent or child of anyone; it just acknowledges the adoption.
The same article requires the adopter and adoptee to personally consent in the authentic act. No one, including the concurring spouses, can sign through a representative or a power of attorney.3Justia Law. Louisiana Civil Code Art 213 – Adult Adoption Form If someone is out of state or incapacitated, there is no workaround. Everyone appears and signs.
Filing, Recording, and When It Takes Effect
Once the paperwork is done, the act of adoption (and the court judgment, if there is one) has to be filed for registry with the clerk of court. Notarial stepparent adoptions file just the authentic act; court-authorized adoptions file the judgment with the act. The filing can be made with the clerk of court in any parish, and the clerk records it in the conveyance records.4Louisiana State Legislature. Louisiana Code RS 9:463 – Adult Adoption Recordation
The adoption is effective when the act and any required judgment are filed for registry. There’s a useful timing rule: if you file within five business days of the last required signature (excluding legal holidays), the effective date rolls back to the date of that signature.4Louisiana State Legislature. Louisiana Code RS 9:463 – Adult Adoption Recordation That five-day window can matter for inheritance and benefit questions tied to a specific date.
What Changes Legally
After the adoption, the adopter is the adoptee’s legal parent for all purposes, and the legal relationship with the former legal parent is terminated.5Louisiana State Legislature. Louisiana Civil Code Art 199 – Effect of Adoption The adoptive parent becomes next of kin for things like healthcare decisions if the adoptee is incapacitated.
Louisiana keeps one door open that most states close. Even though filiation with the former legal parent ends, the adopted adult and their descendants keep the right to inherit from that former parent and from that parent’s relatives.5Louisiana State Legislature. Louisiana Civil Code Art 199 – Effect of Adoption So the adoptee gains inheritance rights from the new parent without losing them from the biological side.
Stepparent Adoptions Go Further
When the adopter is a stepparent (currently married to, or widowed from, one of the adoptee’s parents), the relationship between the adoptee and that parent, and all of that parent’s relatives, is completely unaffected.6Louisiana State Legislature. Louisiana Code RS 9:461 – Effect of Adult Adoption by Stepparent The adoptee adds a parent instead of trading one for another.
Estate Plans Should Be Updated
Because the adoptee counts as a legal child for all purposes, they now have the same inheritance standing as a biological child under Louisiana’s forced heirship and intestacy rules. Wills, trusts, and beneficiary designations belonging to both the adopter and the adoptee are worth reviewing once the adoption is effective, because default outcomes can shift.
Changing the Adoptee’s Name
An adult adoption in Louisiana changes only the adoptee’s name on the birth certificate; the parentage listed on the birth certificate stays as it was.7Louisiana Department of Health. Adoption Information And the name change isn’t automatic.
For anyone 18 or older, Louisiana requires the local District Attorney’s sign-off on the name change. You’ll need a notarized affidavit from the DA stating there’s no objection, and you submit that with the request for a new birth certificate along with a certified copy of the adoption decree or authentic act and a copy of the original birth certificate.7Louisiana Department of Health. Adoption Information
The birth certificate is only the start. Social Security, driver’s license, passport, bank accounts, professional licenses: each has to be updated separately. Nothing syncs automatically.
What Adult Adoption Won’t Do
Two federal points come up often enough to flag.
The federal adoption tax credit is only available when the adoptee is under 18 or is physically or mentally unable to care for themselves.8Internal Revenue Service. Understanding the Adoption Tax Credit A routine adult adoption won’t qualify.
Adult adoption also doesn’t create immigration benefits. The Child Citizenship Act of 2000 gives automatic citizenship to certain foreign-born adoptees of U.S. citizens, but only when the adoption occurred before the child turned 18, and some provisions require it before age 16 with two years of custody and joint residence.9U.S. Citizenship and Immigration Services. Adult Adoptees and U.S. Citizenship An adult adoption in Louisiana does not create a path to U.S. citizenship for a foreign-born adoptee.
Costs
Adult adoption is usually far cheaper than adopting a minor. The main expenses are court filing fees (which vary by parish, so check with the clerk of court where you plan to file), notary fees for the authentic act, and attorney fees if you use one. The notarial stepparent path avoids court filings and hearings, so it tends to be the cheapest. An attorney isn’t legally required, but because a missing spousal signature can void the whole adoption, having someone check the act before signatures go on it is worth the fee for most people.
