“SDCL 34-25-16.4 allows adoptees who have reached the age of 18 to open their own original certificate of birth together with the adoption information that was used to create a new certificate of birth.
Adult adoptees who have reached the age of 18 may use the Application of Adoption Information to request their original birth certificate prior to adoption. The application must be signed in front of a notary public or a copy of valid government-issued photo ID must be submitted with the request. The fee to request original birth records is $15 per each requested copy.
If you are not the adoptee and/or have not reached the age of 18 but wish to open adoption records, please contact Vital Records at (605)773-4961 for further guidance”
