So your boyfriend born in New York,perhaps one of the easiest states for a person who was born in New York to obtain a replacement birth certificate if the need arises. The department Vital Records in New York encourages people to go online to obtain a replacement birth certificate. This helps you to avoid the long lines you will confront by seeking to get your birth certificate in person and the waiting period for getting it by mail.Of course you must have supporting documentation of proof of identity to process your order. You need to be the person whose name is listed on the birth certificate or the parent or guardian of the person listed on the birth certificate. You must have a valid, unexpired state or government identification card. If you are trying to obtain a replacement for someone else, you have to have a notarized letter from that person tendering permission for you to obtain a copy of his or her birth certificate.
