In order to preserve the right to notice and consent to the adoption of the child, an unmarried biological father must, as the "registrant," file a notarized claim of paternity form with the Florida Putative Father Registry maintained by the Office of Vital Statistics of the Department of Health which includes confirmation of his willingness and intent to support the child for whom paternity is claimed in accordance with state law. The claim of paternity may be filed at any time before the child's birth, but a claim of paternity may not be filed after the date a petition is filed for termination of parental rights.
Fla. Stat. § 742.021
