How should I go about unsealing my adoption records?

Actually closed and sealed adoption records are imposed, not chosen. Even in so-called 'open' adoptions the records are sealed by the State upon finalization of the adoption and the adoptee will never be able to apply for the record of birth in the same way non adopted people are able to. Most civilized nations do not withold this information from a human being. However in the United States only Six States have restored the right of adoptees to access their own factual record of birth. Two of those States were never sealed at all. In other States, petition the Family Court where the adoption was finalized and show 'good cause' - which is open to the interpretation of the Judge. Being native American is automatically 'good cause' and they can reconnect with their tribe, yet someone needing bone marrow from a relative have been turned away as not showing 'good cause' :( Join the movement for the restoration of Adoptee Rights so we have equal access to our vital records, just the same as non-adopted adults. adopteerights.net If you amend your Q to say where the birth and adoption took place, you will get more accurate answers

Call the place that handles ur adoption. There are "adoption reunion registries" if both bio parent & adoptee register they will send you both identifying information.

i was also adopted and that was all i wanted to know as well. when i called to open the records they asked if i have a medical reason for it i told them no i just wanted my records and i was now over the age of 18 they said it was closed for a reason and the only way they can reopen it is to have a medical reason from a doctor that was life or death situation. this was done in New York. So your state might be different good luck
