In rare cases, it is possible a court will "set aside" (reverse) an adoption that has already been finalized. This will "reactivate" the original birth certificate, which was previously
sealed and replaced as a result of the adoption.
In order to do this, you would have to prove some sort of fraud on the court or coersion. This is very difficult to prove, and rarely occurs.
The only real chance you have is if all interested parties consent to the reversal.
