You do not adopt your stepparent — rather, your stepparent adopts you. But yes, this is absolutely possible and increasingly popular in Washington DC.
Adult adoption means your stepparent legally becomes your parent. The result:
- Full legal parent-child relationship
- Automatic inheritance rights in both directions
- Medical decision-making authority
- Official family recognition on all legal documents
- A new birth certificate can be issued listing your stepparent
How it works in Washington DC:
- Your stepparent files a Petition for Adult Adoption in Superior Court
- You sign a consent form (the only consent needed)
- No biological parent involvement required
- No home study or background check
- Brief finalization hearing — typically 4-8 weeks
There is no age limit. You could be 25 or 75. The adoption is equally valid and meaningful.
Cost: $349 for document preparation + court filing fees ($100–$400)
Many adult adoptees tell us this is something they have wanted for years. The finalization hearing is deeply emotional — making official what your heart has known all along.
