How to Find a Lost Sibling
Jupiter Images © 2009

If you have the name, date of birth, and place of birth for your lost sibling, you have several private and public resources available to help you locate him. If you lost your sibling due to a closed adoption and do not know identifying information about him, you may need to ask permission of the court for access to your adoption records.

Contact the adoption agency. If you were separated from a sibling due to adoption, the agency that handled your case may be able to open your file and give you contact information for your sibling.

Get a court order to open your file. Each state makes it own laws regarding access to adoptions records. And many jurisdictions require a court order to open adoption files. If you were adopted in a closed-adoption state, you will need to petition the court for an order to open your adoption file and obtain information about your sibling.

Sign up with a reunion registry. Many private companies and non-profit organisations offer free registries for adoptees to enter their contact information and data regarding their adoption so that they may locate birth parents and lost siblings.

Employ a private service. If you have lost touch with a sibling for reasons other than adoption, you may be able to locate them using a private investigation company or private locater service that searches public records.

Search public records on your own. If you know the cities where your lost sibling has lived, you can search for him through public marriage, birth, and property records at no cost. Many of these public records are available online, through the office of the clerk of the court or department of vital records.
