The Florida Administrative Code allows for changes to the gender on a birth certificate if "authentic, certified, or notarized supporting documentary proof" is provided. As proof of gender change, the Bureau of Vital Statistics will accept a regular passport gender change letter. If you do not have a passport, then you will need to provide other proof of identification and residence address as well as a medical report from a doctor who has examined you within 60 days of filing the form. In addition to the passport letter, the vital statistics bureau will accept a state ID card with a female name marker or a hospital discharge summary with the original signature of a physician who has examined you. The form must be signed by someone who has the authority to administer medical treatment and cannot be filed posthumously. The form must also include an affidavit stating that you are living as a woman and will continue to do so for at least 90 days after filing the form. Once the form has been filed, it takes three months for the change to take effect. If you want to file the form earlier, you can apply for a new birth certificate during another mandatory waiting period. The form can be filed with the county clerk's office or with the Department of Health.
