Can the adopted child choose to undo the adoption when they turn 18 in Washington DC?

No. Adoption is permanent and irreversible — it cannot be undone when the child turns 18 (or at any age).

The legal reality in Washington DC:

• Once the Superior Court finalizes the adoption, it is a permanent court order
• There is no "undo" option at age 18 or any other age
• The adoptive parent IS the legal parent — forever
• The child cannot petition to restore the terminated biological parent's rights

Why this exists:

• Permanence provides security for the child
• It creates certainty for the legal family structure
• It protects inheritance rights and other legal benefits
• It prevents the biological parent from later trying to reclaim the child

What the adult child CAN do:

• As an adult (18+), they can choose to seek out the biological parent personally
• They can petition the court to access sealed adoption records (varies by state)
• They can establish a personal relationship with the biological parent (but no legal one)
• They CANNOT reverse the adoption or the legal parent-child relationship with you

This permanence is a feature, not a limitation. It means that when you adopt your stepchild, you are making a commitment that the law will honor forever — just like a biological parent-child bond.
