When a child is adopted through a closed adoption, the records of that adoption are sealed by a judge to make the transaction private. Biological parents will sometimes do this if they do not want to be contacted by their biological child, or if the parties involved agree that it is best if certain information be anonymous. But sometimes a child may grow up and want to contact his biological parents, or she may need to know her parents in the event of a hereditary illness or risk that requires knowledge of family medical history.
Locate the county you were adopted in and contact the county clerk. She will be able to tell you the process of seeking access to your sealed adoption records. There may be certain restrictions and varying orders of procedure--such as a rule that you must be of legal age to make the request on your own--but you will have to go to court no matter what, and the process for arranging that appointment is by filing a petition.
Fill out the petition form with the county court. This is a fairly simple form requesting identifying information from the filer and a brief explanation for the reason for the petition. Once this petition is returned to the county court, a court date will be established.
Meet with the judge at your scheduled date and explain your reason for wanting the adoption records unsealed. Generally, you will have a better chance if your reasoning isn't based solely on personal desire or interest. Medical issues are the most common reason sealed adoption records are unsealed. However, you can consult an adoption lawyer to build the best argument no matter what your reasoning. The judge will either grant your petition and unseal the records or deny your petition. If this happens, you can request a confidential intermediary.
Negotiate with your biological parents and/or their representatives through a confidential intermediary. This is only an option if your parents are still alive (if they are dead, it is usually easier to unseal adoption records). Use the intermediary to explain your reasoning for wanting the records unsealed. If you can reach a mutual agreement, the records can be unsealed.
