Just a correction today:
Here is what the Wisconsin Adoption Records Search law law says, per the website:
Birth parents are required to provide medical/genetic information to the court at the time parental rights are terminated. Updated medical/genetic information may be filed with the Department of Children and Families at any time thereafter. Upon written notification from a licensed medical provider that an adoptee has developed a genetically transferable disease or condition, an effort will be made to notify birth parents.
Actually, the law doesn't say that they must provide updated medical information, only they it "may" be filed....So that gets around the directive to provide the information.
I will correct the original post. --lorraine
