Will my adopted stepchild automatically get my last name in Louisiana?

No — the name change is your choice, not automatic. You decide during the adoption process whether and how to change the child's name.

How it works in Louisiana:

  • In the Petition for Adoption, there is a section for the child's desired name after adoption
  • If you want the child to have your last name, enter it there
  • If you want to keep the child's current name, enter the current name
  • The judge approves the name as part of the adoption order

Your options:

  1. Change to your last name — the most common choice
  2. Keep the current name — completely valid
  3. Hyphenate — combine both names (e.g., Smith-Johnson)
  4. Change first and/or middle name — also allowed

After the adoption:

  • The new birth certificate from Louisiana Office of Vital Records reflects whatever name you chose
  • Update school records, medical records, Social Security, and other documents
  • We include a post-adoption checklist for all name-related updates

If the child is 12+: They must consent to the adoption, which includes any name change. Their preference matters.

There is no extra cost for the name change — it is included in the adoption process and our $349 fee.

Specify your preference on the questionnaire at stepparentadoption360.com/portal/register.
