In some states, (North Carolina, Georgia, Virginia) the city and county of the adoptee’s birth is changed on the amended birth certificate, to where the adoptive parents were living at the time the adoption was finalized. Often, the states will not give the adoptee the correct location of their birth. Some adoptees have been denied passports for having incomplete birth certificates. The hospital may also be omitted on the amended birth certificate, especially if it primarily serves unwed mothers. In the United States, many such hospitals were run by the Salvation Army, and named after its founder, William Booth. By the mid-1970s, all of these hospitals had closed due to high costs and the reduced need for secrecy, as the social stigma of having a child out of wedlock in America had decreased. More and more mothers were raising their child as a single parent (often with the help of the newly created institution of government welfare).
The probate laws of most states in the U.S. prohibit an adoptee from automatically inheriting from his or her birth parents. This applies regardless of whether or not the birth father participated in or agreed to the adoption. Had the adoption not have taken place, any son or daughter would be an heir upon his or her father's death—regardless of who his childhood caretakers were. There can be additional complications if the birth father has subsequently moved to another state. Should a birth parent include an "unknown" adoptee in his or her will, the probate court has no obligation to fulfill this type of request, while "known" adoptees may have the same status as non-family members. However, there is some variation in probate laws from one state to another.
Most open adoptions lie somewhere in the middle, according to Grotevant and McRoy, exchanging letters, pictures, and phone calls, and having face-to-face meetings once or twice a year. Whatever their situation, many families report that relatives and friends condemn openness, and voice fears that the arrangement will make the birth parent want the child back.
