In nearly all US states adoption records are sealed and withheld from public inspection after the adoption is finalized. Most states have instituted procedures by which parties to an adoption may obtain non-identifying and identifying information from an adoption record while still protecting the interests of all parties. Non-identifying information includes the date and place of the adoptee's birth; age, race, ethnicity, religion, medical history, physical description, education, occupation of the biological parents; reason for placing the child for adoption; and the existence of biological siblings.
“Although I’m very open, [his birth mother] drops into and out of our lives as she needs to,” Miller said. After one long absence, when her son was nine years old, she paid for his birth mother to fly from Colorado to California and stay with them for ten days. Miller doesn’t give up, she said, “because I think we need to honor the pieces that we didn’t provide in the makeup of the child.”
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).
Prior to the 1980s, it was common practice to keep adoptions closed. Oftentimes, women facing unexpected pregnancies would temporarily move to another location, have their babies, and return home. The doctor or a child-placing agency would then find an adoptive family, unbeknownst to the birth mother. Clearly, this led to various complications in each of their lives, especially for the adopted child.
It’s important to keep in mind that, while adoption relationships can change, it is more complicated to increase contact than to decrease it. If a birth mother starts with an open relationship and then decides later that she needs distance, she can do this at any time. However, if an adoption is closed and a birth mother wants more contact, then she has to come to an agreement with the adoptive family. Therefore, it is especially important that a birth mother choosing closed adoption is sure that it is what she wants.
Oftentimes the birth and adoptive parents will sign a Post-Adoption Contract (sometimes called an Open Adoption Agreement), putting in writing any promises regarding contact after the adoption is finalized. Even in those states which do not expressly have laws in this area, these agreements can usually be prepared if the parties desire to formalize the agreement. In an increasing number of US states, courts will find these agreements legally enforceable, as long as they serve the best interests of the child. It is not unusual for these agreements to be more like "handshake" agreements, although they offer less protection to a birth parent if the adoptive parent's promises were not honored.
