Adoption does not necessarily end all ties with biological parents. If you were adopted, you may want to locate your birth mother for medical reasons or to know more about who you are and where you came from.
Talk to your adoptive parents
You have to decide whether your adoptive parents are open to talking about this issue. An adoptive mother may be uncomfortable with a child's desire to find a biological parent if it makes her feel as if she is being rejected. She may also be afraid that your search will open you up to hurt if your biological mother rejects you or if there is some embarrassing history behind your adoption. If your adoptive parent is willing to discuss the issue, she may have your original birth certificate or even know one or both of your biological parents.
Contact the agency that arranged your adoption
Even if your adoption was closed so that the records have been sealed by the state, you should be able to get information that does not directly identify your birth mother. You can also leave a letter with the agency asking the agency to give your birth mother your contact information if she asks. You may find that your birth mother has given the agency her contact information with instructions to release it to you if you ask.
Get a copy of your original birth certificate
In states with open adoption laws, if you are 18 or older and were not adopted before these laws took effect, you can request a copy of your original birth certificate from the state agency maintaining these records. The original birth certificate should have your birth mother's name on it.
Sign up for an adoption reunification registry
Some states have adoption reunification registries. If you register with one and your birth mother is also registered or signs up later, you will be notified.
Search courthouse records
If you know the state and county of your birth, the name of the hospital at which you were born and the date and time of your birth, you may be able to search the county courthouse's file of birth certificates to find one matching the facts you have.
Do an on-line search
If you know your birth mother's name and have a good idea of her age, you may be able to locate her using an on-line address search. You may have to pay for the service.
