In 1941, Indiana enacted a law that sealed all original birth certificates and adopted records from public access. This restriction also applied even to adopted children, which means without written approval from the State Board of Health, it was nearly impossible for adopted children to find out who their parents were. The law, however, was modified in 1993 to allow current adoptive children access to their original records, but no provisions were made for the children whose adoptions took place prior to 1994. The records are still unobtainable.
Pam Kroskie has created a non-profit organization, called Hoosiers for Equal Access Records (HEAR). A bill was drafted that would extend record access for those seeking records from 1941 onward. The Indiana Senate approved the bill in the summer, but when it made it to the floor of the House, progress stalled.
