To fix a birth certificate, you apply to the vital records office of the state of birth with an affidavit describing the error and documents that show the correct information. Small errors found soon after birth are simply corrected; later changes are amended and marked as such. A legal name change needs a certified court order.
Correction, amendment or name change
New York explains the difference clearly. A correction fixes a mistake made when the record was filed; no new document is created, and the record shows its change history. An amendment, such as one after an adoption, a court-ordered name change or an acknowledgment of paternity, can produce a new certificate with the original sealed. Getting married or simply using a different name does not change a birth certificate at all.
The usual process
The national model rules describe what most states follow. You file an affidavit that identifies the certificate, the incorrect information and the correct information, together with documentary evidence. The evidence generally has to be old: created at least five years before the application, or within seven years of the birth, so that it reflects the facts rather than the requested change. Texas and Michigan both require the affidavit to be notarized and sent with ID and supporting documents.
Who may ask
Under the model rules, a parent may apply while the registrant is under eighteen, the registrant may apply once eighteen or older, and a legal guardian may apply. Many states follow that pattern, and some let the hospital or other person who filed the birth correct its own errors.
Marked as amended
An amended certificate states that it has been amended, and the state keeps a record of the evidence, the date and who made the change. Minor corrections made within the first year after birth can often be made without that marking. Most states also limit repeat changes: once an item has been amended, changing it a second time usually requires a court order.
Legal name changes
A name change granted by a court does not update a birth certificate on its own. Michigan says so directly: you must send the vital records office a certified copy of the court order, and depending on the order the state either adds the change to the record or issues a new certificate. Given names can often be changed by affidavit only during the first year; after that, a court order is the usual route.
Ordering after a correction with BirthChek
BirthChek orders certified copies; corrections and amendments themselves are filed directly with the state office. Once your record has been changed, order a new certified copy so you have one that shows the corrected information.
