Florida DNA Testing Laws and Your Legal Rights

Florida DNA testing laws cover four very different situations: paternity disputes in family court, mandatory collection from people arrested or convicted of felonies, postconviction testing that can prove innocence, and a general privacy rule that requires your express consent before anyone else analyzes your DNA. The rights you have depend entirely on which of those buckets you are in.

Court-Ordered DNA Testing in Paternity Cases

A Florida court can order the child, the mother, and the alleged father to undergo genetic testing when paternity is disputed. The judge can do this on the court’s own initiative or when a party files a sworn statement claiming or denying paternity and describing facts that make sexual contact between the parties reasonably possible or reasonably unlikely. The testing must be done by a qualified laboratory using methods accepted in the scientific community.¹

A result showing a 95 percent or greater statistical probability of paternity creates a rebuttable presumption that the man is the biological father. He can still present evidence to challenge the finding, but the burden is now his. If he cannot rebut it, the court can enter summary judgment declaring him the legal father. A test that excludes him entirely ends the case with prejudice, meaning it cannot be refiled.¹

Objecting to the Results

Any objection to the test results must be filed in writing at least 10 days before the hearing. Without an objection, the results come into evidence with no additional testimony from the lab. Either side can hire an outside expert to challenge or support the procedure, the result, or the underlying statistics. The court is required to tell each person being tested about the objection process and what happens if they do not use it.¹

Refusing the Test

Refusing a court-ordered DNA test carries real consequences. Judges routinely draw adverse inferences from refusal. An alleged father who refuses may face a default judgment of paternity and the child support obligation that comes with it. A mother who refuses may lose the ability to establish the alleged father’s paternity and forfeit any claim for support. The court decides how the cost of testing is split among the parties.

Mandatory DNA Collection in Criminal Cases

Florida casts a wide net for criminal DNA collection. The samples go into a statewide database run by the Florida Department of Law Enforcement, which feeds the national Combined DNA Index System (CODIS) used by police across the country.²

You are a “qualifying offender” who must submit a sample if you fall into any of these categories:

You are convicted of any felony or attempted felony in Florida, or a similar offense in another state.
You are convicted of certain misdemeanors, including stalking, voyeurism, specified obscenity offenses, and crimes committed to benefit a criminal gang.
You are arrested for any felony or attempted felony in Florida.
You are in law enforcement custody and subject to a federal immigration detainer.

If you are arrested, the sample is taken at booking. If you are incarcerated, it must be collected no later than 45 days before your projected release.³

Outside those mandatory categories, police generally obtain DNA through a search warrant backed by probable cause, through voluntary consent that must be knowing and voluntary to hold up in court, or by collecting genetic material a person left behind in a public place. There is no constitutional protection under federal or Florida law for DNA you abandon in public, such as a discarded cup or cigarette butt.

Getting Your Profile Removed From the Database

If your DNA was collected but the case did not end in a conviction, you can petition FDLE to remove your profile. What you submit depends on how you got into the database.

For arrest-based collection, you give FDLE a certified copy of the no-information filing, the dismissal order, the acquittal, or official documentation that no charges were filed within the applicable time. For conviction-based collection, you submit a certified copy of a final court order showing the conviction was overturned on direct appeal or set aside in a postconviction proceeding. A court order is not “final” for this purpose while time remains for an appeal, or while the case has been sent back for retrial and is not yet fully resolved.⁴

Postconviction DNA Testing

Florida lets people convicted of felonies ask a court to test DNA evidence from their original case. There is no filing deadline. A petition can be submitted at any time after the judgment and sentence become final.⁵

Two groups qualify. If you went to trial and were found guilty of a felony, you can petition for DNA testing that could exonerate you or reduce your sentence. If you pleaded guilty or no contest to a felony before July 1, 2006, you can also petition, but only to seek exoneration, not a sentence reduction.⁵

The petition must be filed under oath and include:

A description of the physical evidence containing DNA, its current or last known location, and how it was originally obtained.
A statement that the evidence was never DNA-tested, or that earlier testing was inconclusive and newer techniques would produce a definitive result.
A declaration of innocence explaining how the testing will prove exoneration or justify a reduced sentence.
An explanation of why the defendant’s identity is a genuinely disputed issue.
Proof the prosecution has been served with a copy.

The court screens the petition and denies it if it is insufficient on its face. If it survives that screen, the prosecution has 30 days to respond. When ruling, the court looks at whether the physical evidence still exists, whether the DNA results would be admissible with reliable proof the evidence has not been altered, and whether there is a reasonable probability the defendant would have received a different verdict or sentence if the DNA results had been available at the original trial. A denial can be appealed within 30 days, and a motion for rehearing must be filed within 15 days of the denial order.⁵

Genetic Privacy Outside Law Enforcement

For everything that is not a criminal investigation or a court-ordered paternity test, Florida’s genetic privacy statute is strict. Under Section 760.40, no person or entity may perform DNA analysis without the express consent of the individual being tested, or that of their legal guardian. Express consent means an affirmative action after you receive a clear disclosure about how the sample will be collected, used, stored, and shared.⁶

The results of any DNA analysis are the exclusive property of the person tested. They are confidential by law, exempt from Florida’s public records requirements, and cannot be disclosed without express consent. Anyone who performs the analysis or receives the results must notify the person tested that the analysis occurred and must tell them whether the results were used in any decision about insurance, employment, a mortgage, a loan, credit, or educational opportunities. If the results contributed to a denial in any of those categories, the analysis must be repeated for accuracy, and if the first analysis turns out to be wrong, the denial must be reconsidered.⁶

Federal Protections and Where They Stop

The federal Genetic Information Nondiscrimination Act (GINA) adds another layer. GINA prohibits employers from using genetic information in hiring, firing, pay, promotions, or any other employment decision. Employers cannot request, require, or purchase genetic information about employees or applicants. “Genetic information” includes your own test results, your family members’ test results, and your family medical history. On the health insurance side, GINA bars health insurers from using genetic information to deny coverage or set premiums.⁷

GINA has a significant gap worth knowing about. It does not cover life insurance, long-term care insurance, or disability insurance. Providers of those products can legally use genetic information when evaluating applications, setting rates, or denying coverage. Florida’s own genetic privacy statute requires notice and an accuracy review when DNA results are used in insurance decisions, but it does not outright ban the practice for those excluded insurance types.⁷

Consumer DNA Kits and Police Access

Law enforcement agencies now use forensic genetic genealogy searching, where crime scene DNA is compared against profiles in public genealogy databases to generate investigative leads. A U.S. Department of Justice interim policy limits federal and federally funded use of the technique to leads in unsolved violent crimes, and it bars uploading DOJ-grant-funded profiles to a nongovernmental database without written approval.⁸

If you submit your DNA to a consumer genealogy service, your genetic profile may be searchable by law enforcement depending on the service’s policies and database settings. Some services let users opt out of law enforcement matching; others open their databases to police searches by default. Florida’s consent requirements under Section 760.40 apply to DNA analysis performed within the state, but they do not control what a third-party company headquartered elsewhere does with data you voluntarily uploaded to its platform. Reading the privacy policy before you mail in a sample is worth the time.
