The District of Columbia Application To Amend Birth Certificate of An Adult is a form used to request a change to an existing birth certificate. This form may be used to correct errors or to update the certificate with new information. There are two types of applications: an amendment to the existing certificate and a substitute certificate. The amendment application requires a written statement outlining the corrections or changes requested, such as correcting misspelled names or adding a parent’s name. The substitute certificate application requires a certified copy of the new birth certificate. Both applications must include supporting documentation such as a court order, a marriage certificate, or other official documentation to confirm the changes. The application is available online or can be obtained from the Vital Records Office in Washington, DC.
