How to File an Unlawful Detainer in Duval County, Florida

Jacksonville-area property owners dealing with an occupant who has no lease and no rent agreement need to file an Unlawful Detainer, not a standard eviction. This guide covers Duval County's exact filing requirements.

What Is an Unlawful Detainer, and Why Isn't It Just an "Eviction"?

An eviction requires a landlord-tenant relationship — meaning rent was owed or agreed to, verbally or in writing. An Unlawful Detainer, under Chapter 82 of the Florida Statutes, is for the opposite situation: no rent agreement exists at all. File the wrong one, and Florida courts will dismiss the case outright.

What You'll Need to File

• Complaint for Unlawful Detainer
• Summons (one per defendant)
• Affidavit of Ownership (if filing pro se, without an attorney)
• Certificate of Mailing (needed if the Sheriff is unable to personally serve the occupant and posts the Summons instead)
• One copy for yourself, plus two copies of the Complaint and Summons for each defendant

A written notice to vacate is not legally required before filing an Unlawful Detainer — but many county Clerk packets recommend sending one anyway as good practice, commonly with a 3-day window, before filing.

Official self-help forms and instructions are available through the Florida Courts Self-Help Center and the Florida Bar's consumer information pages.

The Most Common Mistake: Filing a Standard Eviction Instead

Duval County sees a high volume of eviction filings — cases filed incorrectly as a standard eviction instead of an Unlawful Detainer face real backlog delays getting corrected, not just outright dismissal.

Real Situations We Help With

"My Daughter's Ex Moved In and Refused to Leave"

A homeowner in Jacksonville allowed her daughter's partner to stay temporarily. There was never a lease, never any rent paid. When the relationship ended and he wouldn't leave, a standard eviction was initially filed — and dismissed, because no rent agreement had ever existed. Refiling correctly as an Unlawful Detainer resolved it.

The above is an illustrative example based on a common situation, not an account of a specific individual customer.

What to Expect at a Hearing

If the occupant files a response, both sides will be required to attend a hearing before a judge (not a jury). A few practical things to know:

• Address the judge as "Your Honor" or "Judge," and do not interrupt while they are speaking
• A bailiff (a deputy sheriff) maintains order in the courtroom and will direct you where to sit
• The burden of proof is on you as the person bringing the case — simply telling your story may not be enough. Bring documentation, texts, or other evidence supporting your claim that no lease or rent agreement ever existed
• Evidence presented must generally conform to Florida's Rules of Evidence (Chapter 90, Florida Statutes) to be considered by the judge
