A legal name change is a chancery case filed in the circuit court of the county where you live, governed by § 68.07, Florida Statutes, using the Supreme Court–approved family law forms (Form 12.982 series).
The petition is filed in the circuit court of the county of residence and must state the facts § 68.07 requires — including prior names, residence history, occupation, and whether you have ever been adjudicated bankrupt or convicted of a crime (§ 68.07(3), Fla. Stat.).
Unless the petition only restores a former name, the petitioner must submit fingerprints for electronic processing by the Florida Department of Law Enforcement and the FBI before the hearing (§ 68.07(2), Fla. Stat.). Minor name changes are petitioned by parents or guardians under the same statute.
The court holds a hearing and, on the statutory showing, enters a final judgment changing the name. Certified copies of the judgment are what the DHSMV, Social Security Administration, and passport agencies require to update records.
