Ask anyone who handles Florida Lemon Law cases what separates strong claims from weak ones, and the answer is rarely the defect. It is the file. Two owners with the same broken transmission can end up in very different places depending on what they can prove.
The encouraging part: the evidence a lemon claim needs is ordinary paperwork, most of which passes through your hands anyway. This checklist covers what to keep, why each item matters, and how to fill gaps.
The purchase file
Start with the documents from the day you got the vehicle.
The purchase or lease agreement establishes the price, the trade-in, the taxes and fees, and the date. Those numbers drive the refund formula described in the refund calculation guide.
The finance contract or lease shows the interest you pay, which a repurchase refunds. The window sticker or build sheet documents the equipment, which matters if a comparable replacement vehicle is ever on the table. The warranty booklet matters twice: it defines the coverage, and it lists the manufacturer's address for the defect notification.
The delivery date deserves special attention, because the 24-month Lemon Law Rights Period runs from it. The dated delivery receipt or the contract itself usually proves it.
The repair file: the heart of the case
Every visit to the dealer should produce a repair order, and every repair order belongs in your file. Each one should show four things:
- The date the vehicle went in and the date it came out
- Your complaint, in your words
- The work performed and parts replaced
- The mileage at the visit
Those four fields carry the whole statutory framework, and a missing one weakens the order that contains it. The complaint lines establish that the same defect kept returning, which feeds the three attempts rule explained in the three repair attempts guide. The in and out dates establish the cumulative days for the days out of service path. The mileage at the first relevant visit fixes the use offset in the refund math.
Two habits protect this file. First, never leave the service department without paperwork, even when the visit was quick and nothing was found; a no-fault-found visit is still a repair attempt. Second, read the complaint line before you leave. If it does not describe what you actually reported, ask for it to be corrected.
Your own log
A simple contemporaneous log multiplies the value of the official paperwork. The format does not matter; notes on a phone work. Each entry: the date, what the vehicle did, where, and what it interrupted.
The log fills the gaps repair orders leave. It captures the occurrences that did not result in a visit, the conversations with service advisors, the callbacks advisors committed to, and the rental car days. When a defect is intermittent, the log is often the only evidence of how often it really happens. Photos and videos belong here too: a dashboard warning, a puddle under the engine, a screen gone black. Date-stamped media is hard to argue with.
