Nassau County, Florida, has about 104,000 residents (2024 Census Bureau estimate).

Criminal Cases in the Nassau County Circuit Court
In Florida the public criminal record is the court file. Criminal cases from Nassau County are heard by the Nassau County Circuit Court, which hears felonies, civil cases over $50,000, divorces, probate and juvenile matters; the County Court takes misdemeanors, traffic cases, small claims and civil cases up to $50,000, and the file of each case is kept by the Clerk of the Circuit Court and Comptroller.
The court records page SearchSystems verified for the county is at flcourts.gov/Florida-Courts/Court-Locations/First-District/Nassau (page title: - Florida Courts), which answered when SearchSystems opened it on September 23, 2026.
Florida has no single public index of every trial court case; each court's records are looked up through that court.
The Florida Criminal History and Your Own Copy
Florida is one of the states that lets anyone look up another person's statewide criminal history: anyone can run a name-based criminal history search online for $24, for $24 a search, through the Florida Department of Law Enforcement. The result is the repository record, what agencies reported to the state, which is wider than one county's court index but can lag it. The search is on the Florida Department of Law Enforcement site.
Arrest Records Kept Locally in Nassau County
The Nassau County Sheriff's Office and the agency that reports for Fernandina Beach keep the arrest records in Nassau County: the report and the booking record of each arrest stay with the agency that made it, separate from the court file and from the state repository.
The FBI's agency list also places five state agencies and one state police unit in Nassau County (the arrest records guide names each one); each keeps the records of its own arrests.
The agencies and their counts, year by year, are in Nassau County arrest records.
The Crimes Behind the Records: Nassau County in 2025
The two agencies in Nassau County with all twelve months of 2025 on file reported 140 violent and 199 property crimes to the FBI that year; the same agencies with both 2025 and 2024 complete reported 339 crimes in 2025 against 332 in 2024. Each reported crime is a report on file with the agency that took it, and each arrest that follows is the start of a criminal record.
The full crime section, agency by agency, is on the Nassau County public records guide.

The Sex Offender Registry for Nassau County
Registered sex offenders living in Nassau County are listed on the Florida Sexual Offenders and Predators Registry, run by the Florida Department of Law Enforcement at offender.fdle.state.fl.us. The registry is public and can be searched online.

Asking an Agency in Nassau County for a Record
An arrest report, a booking record or a local criminal history letter comes from the agency that holds it, not from the court.
Under the Florida Public Records Act (Chapter 119) a county office must answer a request promptly and in good faith; the statute sets no number of days, and it may charge the copy fees set by statute, plus a special service charge for large requests.

(page title: Public Records Request/Fee Schedule | Nassau County Sheriff's Office).
