"Do you believe that Open Records Legislation should include the rights of mothers to identifying information?
on the children that they surrendered their right to parent?"
Absolutely. Either party not having access to information that pertains to them is archaic.
"Do you think that the Adoptive Parents should have the right to the mother's identifying information after the Adoptee reaches adulthood?"
I think maybe something should be done so that if the child, after they reach adulthood, are unable to look after themselves for some reason (special needs, etc.), then it should be opened up to adoptive parents, as their guardians. That could likely be accomplished with a simple "Power of Attorney". Otherwise, I don't see why. If the adoptee is an adult, the info belongs to them.
"Do you think that many adoptive parents already have identifying information on the mothers?"
Well, that's hard to say, since I am primarily in the foster care arena. We obviously have a certain amount of information, and the goal, according to any social worker I've dealt with, is for "openness when safe and possible". I know personally, more than a few adoptive parents who have done private domestic infant adoption, WANTED an open adoption, and now aren't able to get ahold of their child's first mother (or father...there is one case where mom was deceased and the afamily wanted the first father involved). So, they do have identifying information, but sadly, still no contact with first family.
Not only does it help adoptive families to have openness for clinical reasons (medical, etc.), but it also helps for their children to be generally happier and more well-adjusted. I think most AP's that I talk to now understand that, and strive for it when "safe and possible".
