A contingency fee agreement is the dominant fee structure in US plaintiff personal injury, employment discrimination, and consumer protection litigation. The lawyer takes a percentage — typically one-third before suit is filed and 40% after — of any recovery, and the client pays nothing if there is no recovery. The trade-off is steep: in a successful case, the lawyer's share can dwarf what you take home after costs and liens. ABA Model Rule 1.5(c) requires every contingency fee agreement to be in writing, signed by the client, and to specify how the fee is calculated, what costs are deducted, and whether costs come off the top or after the lawyer's percentage. State bar rules often add more — California, New York, Texas, and Florida each have their own contingency fee statutes. The clause that governs deduction order, expense responsibility, and lien handling is typically more important than the headline percentage.
What is a Contingency Fee Agreement?
A contingency fee agreement is a written contract under which a lawyer's compensation is a percentage of the client's recovery rather than an hourly or fixed fee. It is governed by ABA Model Rule of Professional Conduct 1.5(c), state bar rules (e.g., New York 22 NYCRR 1215; California Business and Professions Code § 6147; Florida Bar Rule 4-1.5(f)), and applicable substantive statutes (e.g., medical malpractice fee caps under N.Y. Judiciary Law § 474-a). Required disclosures typically include the fee percentage, the deduction order, costs treatment, and the client's right to a written settlement statement at the conclusion.
Red flags to watch for
Whether the percentage is calculated on gross recovery (before costs) or net recovery (after costs) materially affects what you take home. ABA Model Rule 1.5(c) requires this method to be stated. A 40% gross recovery contingency fee with $50,000 in costs and a $250,000 settlement leaves the client with $100,000 — versus $120,000 under a net recovery calculation.
Many agreements step up from 33% pre-suit to 40% after suit and 45% after appeal. Some go higher. Each step should be tied to a specific event (filing complaint, completion of discovery, jury verdict). Vague triggers like 'preparation for trial' invite disputes.
Under ABA Model Rule 1.8(e), a lawyer may advance court costs and expenses, repayment of which may be contingent on outcome. If the agreement requires you to repay costs even if you lose the case, ask why — and whether your state bar permits or restricts that arrangement.
In personal injury cases, ERISA plan liens, Medicare/Medicaid subrogation, and hospital liens often consume a substantial portion of net recovery. A retainer agreement that does not address how liens are handled — and how they affect the lawyer's fee calculation — is non-transparent. Some jurisdictions (e.g., Florida) require lien disclosure as part of contingency fee disclosures.
ABA Model Rule 1.2(a) gives the client the absolute right to decide whether to accept a settlement offer. A clause that purports to give the lawyer authority to settle without client consent is unenforceable and unethical.
If you change lawyers mid-case, the original lawyer is typically entitled to a quantum meruit fee — but the agreement's specific language affects how this is calculated. A clause that purports to entitle the discharged lawyer to the full contingency percentage regardless of work done is challengeable.
Your legal rights
US clients in contingency fee arrangements are protected by: ABA Model Rules of Professional Conduct (particularly Rules 1.2, 1.5, 1.8, 1.16) as adopted in their state; state bar contingency fee disclosure statutes (e.g., California Business and Professions Code §§ 6147–6148; New York 22 NYCRR Part 1215; Florida Bar Rule 4-1.5(f)); state constitutional and statutory contingency fee caps in specific case types (e.g., medical malpractice); the right to discharge a lawyer at any time, paying a quantum meruit fee for work performed; and federal substantive law caps where applicable (e.g., 28 U.S.C. § 2678 for FTCA cases caps fees at 25%). Disputes are heard in state bar fee arbitration programs (often mandatory in California and New York), state disciplinary boards, or civil court.
Questions to ask before you sign
- 1Is the fee percentage calculated on gross recovery or net of costs, and at what stage do percentages step up?
- 2What costs and expenses will be advanced, and am I responsible for repaying them if we lose?
- 3How will medical, ERISA, Medicare, or other liens be handled — and does that affect the fee calculation?
- 4Will I receive a written settlement statement at the conclusion showing all deductions?
- 5What happens if I want to change lawyers mid-case — what fee will you be entitled to?
- 6Is fee arbitration available with the state bar if we disagree about fees, and is it mandatory or optional?
