I am not so sure about that. there was someone on here that had been adopted in hawaii, the birth records were amended and the original info sealed...but I can’t remember the details.
The original info may be sealed - from prying eyes. but the family or the person whose records they are can go back and see the originals if they so choose.
Not only in Hawaii, but it was quite common in Obama days and probably now, when children were adopted,records were sealed. The only way they could be opened is if both natural parents agreed when the child requested to know who they were.
It had to do with parents objecting to the grown children contacting them out of the blue.
Very odd people have children.
