Florida Bar Rule 4-1.5 is the ethics rule that governs attorney fees and costs in Florida. It bars any fee that is illegal or clearly excessive, requires lawyers to communicate the basis of their charges in advance, forces written agreements whenever any portion of a payment is nonrefundable, caps contingency percentages on a published sliding scale, and gives clients three business days to cancel a signed contingency contract. If you are hiring a Florida lawyer or looking over a fee agreement you have already signed, the rule sets the floor for what the attorney must do and tells you where you can push back.
When Is a Fee Reasonable
Rule 4-1.5(a) prohibits any fee that is illegal, obtained through fraud, or clearly excessive. A fee is clearly excessive when a competent lawyer would be firmly convinced that the amount far exceeds what the work justified.1The Florida Bar. Florida Rules of Professional Conduct
The rule lists specific factors used to measure a fee against that standard:
- The time required and the complexity or novelty of the legal questions.
- Whether taking your case prevents the lawyer from accepting other work.
- The customary rate charged for similar services in the area.
- The amount at stake and the result obtained.
- Time limits you imposed or the circumstances created.
- The length and nature of the lawyer’s relationship with you.
- The experience, reputation, and ability of the lawyer handling the work.
- Whether the fee is fixed or contingent.
These factors apply to every fee structure, so a lawyer cannot escape the reasonableness test by relabeling a charge. If the total does not hold up under the factors, it is excessive no matter what the invoice calls it.
What Has to Be in Writing
Rule 4-1.5(e) requires the lawyer to tell you the basis or rate of the fee before starting work, or within a reasonable time after. For any meaningful engagement that communication should be in writing, and it should spell out the scope of representation, which tasks the lawyer will perform, how billing works, and the rate or amount.1The Florida Bar. Florida Rules of Professional Conduct
A written agreement is mandatory the moment any part of the fee is nonrefundable. The document has to identify exactly which portion is nonrefundable and explain why. If a lawyer tells you a retainer is nonrefundable without putting that in writing, the rule has already been violated. Ask for the written explanation before you pay.
Retainers, Flat Fees, and Advance Deposits
Florida treats three kinds of upfront payment differently, and the label controls where the money sits and who owns it.
A retainer secures the lawyer’s future availability. It is not payment for work. A flat fee is a lump sum covering all services for the full representation and can be designated nonrefundable. An advance fee is money you pay upfront that the lawyer draws from as hours are billed, earned incrementally rather than all at once.
An advance fee must stay in the lawyer’s trust account until it is earned through actual work. A nonrefundable retainer or nonrefundable flat fee belongs to the lawyer on receipt and does not go into trust. If a single payment covers both an advance fee and a nonrefundable portion, the entire check first goes into the trust account, and the nonrefundable portion is withdrawn within a reasonable time.2The Florida Bar. Florida Rules Regulating Trust Accounts
Chapter 5 of the trust account rules reinforces that framework. Client funds must be held in a separate, clearly labeled trust account at a federally insured Florida institution. A lawyer may only withdraw earned fees that are not in dispute, and anything the client contests stays in trust until the disagreement is resolved.
Contingency Fee Caps
In personal injury, property damage, and wrongful death cases, Rule 4-1.5(f)(4)(B) caps the lawyer’s percentage based on how far the case has progressed and how much is recovered.1The Florida Bar. Florida Rules of Professional Conduct
Before the Defendant Files an Answer
- 33 1/3% of any recovery up to $1 million
- 30% of the portion between $1 million and $2 million
- 20% of any amount above $2 million
After the Answer Is Filed, Through Entry of Judgment
- 40% of any recovery up to $1 million
- 30% of the portion between $1 million and $2 million
- 20% of any amount above $2 million
When Liability Is Admitted and Only Damages Are Contested
- 33 1/3% of any recovery up to $1 million
- 20% of the portion between $1 million and $2 million
- 15% of any amount above $2 million
Appeals and Post-Judgment Collection
If the case goes to appeal, or post-judgment action is required to collect, the lawyer may add 5% to the recovery on top of the percentages above.
One contract detail matters as much as the percentage: the agreement must state whether litigation expenses are deducted before or after the fee is calculated. If costs come out first, the percentage applies to a smaller number. If costs come out after, the lawyer takes a percentage of the gross and you pay costs from what is left. The difference can run into thousands of dollars, so check which method your contract uses.
Costs Are Separate From the Fee
Filing fees, process server charges, expert witnesses, deposition transcripts, and medical records are case costs, not attorney fees. Rule 4-1.5(b)(2) says costs also have to be reasonable and lists the factors used to evaluate them: whether the lawyer disclosed costs upfront, whether a written agreement specifies how they are calculated, the actual amount charged by third parties, and whether each cost can be traced to your case. When the fee agreement includes a written method for calculating costs, those charges are presumed reasonable. At the end of a contingency case, the lawyer must prepare a closing statement itemizing every cost and every fee paid to each lawyer who participated. You are entitled to see exactly where your recovery went.
The Statement of Client’s Rights and the Three-Day Cancellation Window
Before you sign a contingency fee contract, your lawyer must hand you a Statement of Client’s Rights and give you time to read and understand each item. You and the lawyer both sign the statement, you keep a copy, and the lawyer keeps one in the file.
The contract itself has to confirm that you received and read the statement before signing. It also has to tell you, in writing, that you can cancel the contract within three business days of signing by giving written notice. Cancel in that window and you owe no fees for work the lawyer performed during those three days. The lawyer may still ask for reimbursement of money already advanced to third parties on your behalf, such as filing fees or records charges.
If a lawyer skips the Statement of Client’s Rights or rushes you past it, treat that as a warning.
Medical Malpractice: Tighter Caps From the Constitution
Florida’s Constitution imposes a stricter ceiling on contingency fees in medical liability cases. Article I, Section 26 guarantees the claimant at least 70% of the first $250,000 in damages and at least 90% of everything above that, after reasonable costs are deducted. That leaves the lawyer with no more than 30% of the first $250,000 and 10% of any additional recovery.3FindLaw. Florida Constitution Art. I, Section 26
These limits apply automatically. A client can waive them, but the waiver requires informed consent: you must be told that you are not required to sign it and that you have the right to consult a separate attorney before giving up the protection. A waiver signed without those safeguards is suspect.
Fees a Florida Lawyer Cannot Charge
Two categories are off-limits for contingency arrangements, regardless of what the client agrees to.
A Florida lawyer cannot charge a contingency fee in a criminal case. The reasoning is that a lawyer’s advice on whether to go to trial or accept a plea should not depend on how the lawyer gets paid.
A contingency fee is also prohibited in domestic relations matters when the fee depends on securing a divorce or on the size of the alimony, support, or property settlement awarded. The rule removes any financial incentive for the lawyer to push a particular outcome in a family case.
Shared Fees and Referral Arrangements
When lawyers at different firms split a fee, Rule 4-1.5(g) requires two things: the total has to remain reasonable, and the client has to agree to the arrangement in writing.4The Florida Bar. Practice Tips – Referral Fee Basics The division can either track the actual work each lawyer performs, or follow a written agreement in which both firms assume joint legal responsibility for the representation and remain available to the client. Under the joint-responsibility route, the agreement with you must disclose that the fee is being divided and how.
In contingency cases for personal injury, property damage, and wrongful death, a referring lawyer who takes on only secondary responsibility is capped at 25% of the total fee. Anything above 25% is presumed clearly excessive unless both firms participated substantially equally in the legal work and obtained court approval.
Joint responsibility is not a formality. Both firms are liable to you for the quality of the work and the outcome, and both should be reachable when you have questions.
Challenging a Fee You Believe Is Excessive
If you think you were overcharged, the Florida Bar runs two free programs that let you resolve the dispute outside court.
Fee Arbitration
Fee arbitration is binding. Both sides have to consent, and once the arbitration agreement is signed neither party can walk away without the other’s permission. A single arbitrator handles disputes of $15,000 or less; larger amounts go to a three-member panel that must include at least one non-lawyer and one lawyer. The arbitrators issue a written decision that is enforceable as a court judgment.5The Florida Bar. Fee Arbitration Procedural Rules The program itself is free, though you pay your own costs if you bring a lawyer to the hearing.6The Florida Bar. Fee Arbitration Program Agreement to Arbitrate A lawyer who loses an arbitration award and fails to pay within 30 days becomes delinquent with the Bar and cannot practice until the delinquency is cured.7The Florida Bar. Lawyer Discipline – A Roadmap to Florida’s Lawyer Regulation System
Grievance Mediation
If you would rather negotiate than hand the decision to a third party, a Bar-approved mediator can help both sides reach a voluntary agreement. The process is confidential and neither side is bound unless both accept a resolution.8The Florida Bar. Fee Disputes? The Florida Bar Offers Two Free Solutions Mediation can also run before an arbitration hearing without delaying it; if the parties settle, the hearing is cancelled.
When a Fee Dispute Becomes an Ethics Complaint
A disagreement over the amount of a fee is not, by itself, a disciplinary matter. The Bar steps in when the amount demanded is clearly excessive, extortionate, or fraudulent, or when the fee violates a specific prohibition in the rule. A lawyer who voluntarily submits to arbitration can point to that willingness as a mitigating factor if a complaint is later filed.
