If an American citizen has a child while living in Spain, he or she needs to report the birth to the nearest U.S. Consulate before the child turns 18. Once the birth has been reported, the consulate will issue a Consular Report of Birth Abroad of a Citizen of the United States of America, also called a Consular Report of Birth or FS-240. As soon as the registration of the birth has been approved, the consulate will issue an original copy of the FS-240 to the parents. If you need to get a copy of this certificate once you have returned to the U.S., you will need to apply through the U.S. Department of State.
Write a letter requesting a copy of the FS-240. The letter must include the child's full name at birth (along with any adopted names); the names of the parents; the date and place of the birth; serial number of the FS-240 (if you know it); and any available passport information for the parents and the child.
Sign the letter and have it notarized.
Photocopy your valid photo ID and include the photocopy with the letter of request.
Purchase a money order, or write a check from a U.S. bank account for $30. Make it payable to "Department of State."
Mail the letter of request and payment to:
Vital Records Section Passport Services 1111 19th Street, NW, Suite 510 Washington, D.C. 20522-1705

A DS-1350 contains the same information as the FS-240; is acceptable for all legal purposes; and can be obtained in multiple copies by the process outlined above. The fee is $30 for the first copy and $20 for each additional copy.
If you will be in the D.C. area, walk-in services are available Monday through Friday from 9 a.m. to 11 a.m. and from 2 p.m. to 3 p.m. at the above office. You don't need an appointment, but you need a valid photo ID to enter the building.
Be prepared to wait several weeks to receive the document. Keep passport and all other relevant documents handy in case the Department of State should request copies.
