What Is a Demand Letter? The 2026 Florida Guide to Demand Letters in Injury and Insurance Claims

A demand letter is a formal written request that another party pay money, perform an obligation, or correct a wrong by a stated deadline, sent before a lawsuit is filed. In a Florida personal injury or insurance claim, the demand letter is the document that converts a pile of medical records, wage records, and repair estimates into a single number, explains why the recipient is legally responsible for that number, and sets a date by which the recipient must respond. It is not a court filing and it is not a lawsuit. In most cases it is the last low-cost off-ramp before litigation, and it is where a large share of Florida claims actually resolve.

This guide was written by the trial attorneys at The Farber Law Firm in Coral Gables for Florida claimants, business owners, and policyholders. It explains what a demand letter does, the parts a serious one contains, the statutory pre-suit notices Florida law requires in specific case types, and the mistakes that quietly cost claimants money. It is general legal information about Florida law as of August 2026, not legal advice about your matter.

What a demand letter actually does

A demand letter serves four separate functions, and a letter that does only the first one is usually ignored.

• It communicates a number. The recipient cannot evaluate what you have not quantified.
• It builds the liability record. It states the facts, identifies the legal duty breached, and attaches the proof.
• It creates a deadline. A response window converts an open-ended conversation into a decision point.
• It preserves leverage. In some Florida claim types, a properly served notice starts a statutory clock or unlocks remedies that are unavailable without it.

There is also a defensive function that claimants often miss. A demand letter is discoverable in later litigation. Anything you overstate, misdate, or omit will be shown to a jury next to the medical records. Adjusters and defense counsel read demand packages looking for internal inconsistencies as much as they read them looking for a settlement figure.

Is a demand letter required in Florida?

For an ordinary negligence claim, no. Nothing in Florida law requires you to send a demand letter before filing a negligence suit arising from a car crash, a slip and fall, or most other injury events. Sending one is a practical choice, not a legal prerequisite.

But Florida imposes mandatory pre-suit notice in several specific categories, and in those categories the notice is jurisdictional or claim-preserving. Skipping it can get a case dismissed or a remedy stripped even when the underlying claim is strong.

First-party residential and commercial property insurance claims

Fla. Stat. § 627.70152 requires a claimant to serve a written notice of intent to initiate litigation on the insurer, through the Department of Financial Services, at least ten business days before filing suit on a property insurance policy, and no later than the applicable limitations period. The notice must state the alleged acts or omissions, the disputed amount, and the amount of attorney fees and costs incurred to date, and must attach a pre-suit settlement demand and the estimate of damages. The insurer must respond within ten business days and may accept, reject, or demand appraisal. Serving this notice incorrectly is one of the most common reasons Florida property insurance suits get dismissed.

Bad faith claims against an insurer

Fla. Stat. § 624.155 requires a Civil Remedy Notice filed with the Department of Financial Services, identifying the statutory provisions violated, the facts, and the policy language at issue. The insurer then has sixty days to cure by paying the damages or correcting the conduct. If it cures, no bad faith action lies. A Civil Remedy Notice is a distinct document from an ordinary demand letter, and drafting one loosely gives the carrier a cure defense.

Medical malpractice

Chapter 766 requires a pre-suit investigation, a verified written medical expert opinion corroborating negligence, and a Notice of Intent to Initiate Litigation served on each prospective defendant, followed by a ninety-day investigation period during which the limitations period is tolled. There is no way to shortcut this for a Florida medical negligence claim.

Claims against a government entity

Fla. Stat. § 768.28(6) requires written notice to the appropriate agency and, for state agencies, to the Department of Financial Services, before suing the state or its subdivisions. The claim must be presented in writing within three years of accrual for most claims, and the agency has one hundred eighty days to investigate before suit can be filed. Sovereign immunity limits also cap recovery per § 768.28(5) absent a legislative claim bill.

Construction defect claims

Chapter 558 requires a written notice of claim describing the alleged defects, served on the contractor, subcontractor, supplier, or design professional, with an opportunity to inspect and offer to repair before suit.

What a strong Florida demand letter contains

A demand package in a serious injury case is rarely a one-page letter. It is a letter plus an organized evidentiary exhibit set. The letter itself generally moves through the following sections.

Identification of parties, policy, and claim

Name the claimant, the insured, the claim number, the date of loss, the adjuster, and the policy or policies implicated. In a Florida auto case that usually means bodily injury liability, personal injury protection, uninsured or underinsured motorist coverage, and any umbrella or resident-relative policy.

The liability narrative

State what happened in chronological order with citations to the proof: the Florida Traffic Crash Report, scene photographs, surveillance, 911 audio, witness statements, incident reports, maintenance logs. Then connect those facts to the legal duty. In a premises case that usually means Fla. Stat. § 768.0755 and the transitory foreign substance knowledge requirement. In a rear-end case it means the rebuttable presumption of negligence against the following driver. In a commercial vehicle case it may mean federal motor carrier regulations and negligent hiring or retention.

Comparative fault, addressed head-on

Since HB 837 took effect in March 2023, Fla. Stat. § 768.81 bars recovery entirely for a claimant found more than fifty percent at fault in most negligence actions, and reduces recovery proportionally below that threshold. A credible demand letter anticipates the carrier's fault argument and answers it with evidence rather than ignoring it.

Injuries, treatment, and causation

Summarize the emergency care, diagnostic imaging, specialist treatment, procedures, therapy course, and current status. Identify the treating physicians by name and specialty. Address pre-existing conditions directly. Florida juries and adjusters both discount claims where prior treatment for the same body part surfaces later in records the claimant never mentioned.

Economic damages

Itemize medical bills, and be careful about the number you use. Billed charges, contractual adjustments, letter of protection balances, and amounts actually paid are different figures with different evidentiary treatment in Florida. HB 837 amended the admissibility of medical damages evidence, so present both what was billed and what remains outstanding rather than a single unexplained total. Add lost wages with employer verification, loss of earning capacity where supported by a vocational or economic opinion, out-of-pocket costs, mileage, and future care supported by a treating physician or life care plan.

Non-economic damages

Describe how the injury changed daily function in concrete, verifiable terms: the specific work tasks that are no longer possible, the sleep disruption, the activities given up, the caregiving burden shifted to a spouse. Adjectives do not move claim values. Specific, corroborated facts do.

The demand and the deadline

State a single, specific dollar figure and a response deadline, commonly thirty days. Explain how the figure was derived. Attach the exhibit index. State that the demand is made for settlement purposes and is inadmissible under Fla. Stat. § 90.408, which excludes evidence of settlement offers and negotiations to prove liability or the amount of a claim.

What to attach, and what not to

Attach the documents that prove the elements: crash or incident report, photographs, medical records and bills keyed to an index, imaging reports, wage documentation, and any expert or treating physician narrative. Attach a declarations page if you are making an uninsured motorist claim.

Be far more careful with three things. First, a blanket medical authorization gives a carrier access to your entire history rather than the records relevant to the claim. Second, a recorded statement given before your treatment course is complete freezes an incomplete description of your injuries. Third, social media content that contradicts a functional limitation will surface, and it is routinely subpoenaed.

Timing: when to send it

The general rule in an injury case is to send the demand after the claimant reaches maximum medical improvement, or after a treating physician can state the permanent condition and future care needs with reasonable medical probability. Demanding earlier usually means demanding on incomplete damages, and Florida releases are final.

Timing is bounded by hard deadlines that a demand letter does not pause. Under Fla. Stat. § 95.11(5)(a), as amended by HB 837, most negligence causes of action accruing on or after March 24, 2023 carry a two-year limitations period. Wrongful death actions are governed by § 95.11(4)(d). Claims under an insurance policy for property loss are governed by § 627.70132, which requires notice of a hurricane or windstorm claim within one year of landfall and a supplemental claim within eighteen months. Personal injury protection benefits require initial treatment within fourteen days of the crash under § 627.736(1)(a). A negotiation that is still open when a deadline runs is a claim that is gone.

What happens after you send it

Expect one of five outcomes: acceptance at the demanded figure, which is uncommon; a counteroffer, which is the normal path; a request for additional documentation, which may be genuine or may be a delay tactic; a denial with stated reasons, which tells you what the litigation defense will be; or silence. Silence past the deadline is itself information. In a first-party property claim it may support the pre-suit notice under § 627.70152 and, where the conduct fits the statute, a Civil Remedy Notice under § 624.155.

Counteroffers in Florida injury claims often open low relative to the demand. That is a negotiating posture, not a verdict on the claim. What moves a carrier is the demonstrated ability and willingness to try the case, which is why the quality of the liability record in the demand package matters more than the adjectives in it.

Common mistakes we see in Florida demand letters

• Demanding a number with no derivation, so the adjuster has nothing to evaluate or approve internally.
• Sending before maximum medical improvement and locking in an incomplete damages picture.
• Ignoring comparative fault under § 768.81 and letting the carrier frame the fault narrative first.
• Using a single billed-charges total without addressing what was paid or remains owed.
• Missing a statutory pre-suit notice in a property, bad faith, malpractice, government, or construction defect claim.
• Attaching a blanket medical authorization instead of the specific relevant records.
• Treating the response deadline as the limitations deadline. They are unrelated.
• Overstating facts that the records later contradict, which damages credibility on everything else.

Do you need a lawyer to send a demand letter?

No. Any person can write and send a demand letter, and for a small property damage dispute with clear liability that is often the sensible route. The calculus changes when the claim involves disputed fault, permanent injury, multiple coverage layers, a commercial or governmental defendant, or a statutory pre-suit notice, because in those matters the letter is the first exhibit in a case file rather than a piece of correspondence.

If you are weighing whether to send a demand yourself, the practical question is whether you can prove causation and quantify future damages without expert support. If the answer is no, a consultation before you send anything is worth more than a consultation afterward, because the demand cannot be unsent and the records cannot be unattached.
