Contingency Fees Explained: Percentages, Ethics & Medical Liens

The System That Funds the Courthouse

Without contingency fees, most personal injury and civil rights litigation simply would not happen. A plaintiff facing $500,000 in damages from a trucking accident cannot afford to pay $400 per hour for the 500+ hours of attorney time needed to litigate the case. Contingency fees — where the attorney collects a percentage of the recovery rather than an upfront hourly fee — solve this access-to-justice problem by aligning the attorney's financial interest with the client's outcome. American attorneys collect an estimated $30–40 billion per year in contingency fees, making it the predominant fee structure in personal injury, mass tort, employment discrimination, and consumer class action practice.

The arrangement is uniquely American. Most other common-law jurisdictions either prohibit contingency fees (England, historically) or regulate them so heavily that they function differently. England's conditional fee arrangement (CFA) allows attorneys to charge an "uplift" on their standard rate if successful, but not to take a percentage of damages.

Standard Contingency Fee Tiers

Contingency fee percentages are not set by law in most states — they are products of contract, subject to ethical reasonableness requirements. Industry norms have settled around a tiered structure that increases at litigation milestones, reflecting the escalating time and risk attorneys bear as cases progress.

Medical malpractice and family law cases often use different fee caps. MICRA (California's Medical Injury Compensation Reform Act) caps contingency fees in medical malpractice cases at 40% of the first $50,000, 33.33% of the next $50,000, 25% of the next $100,000, and 15% of damages above $600,000. California's 2023 MICRA reform increased these thresholds. Federal statutes cap contingency fees in Social Security disability cases at 25% of past-due benefits (capped at $7,200 as of 2024).

Costs: Who Pays and When?

Contingency fee agreements govern not just the percentage but also the treatment of case expenses — filing fees, deposition costs, expert witness fees, medical record retrieval, court reporters, and jury consultants. Two contrasting approaches are common:

• Costs deducted before fee calculation: The attorney's percentage applies to the net recovery after costs are subtracted. This is more favorable to the client. Example: $1 million settlement, $50,000 costs, $950,000 net; 33% fee = $313,500 attorney fee, $636,500 to client.
• Costs deducted after fee calculation: The fee applies to the gross recovery, then costs are deducted. More common in complex cases. Example: $1 million settlement, 33% = $330,000 fee; remaining $670,000 minus $50,000 costs = $620,000 to client.

Clients must scrutinize which approach their agreement uses — the difference on a million-dollar case can exceed $16,000. Ethical rules require the method to be specified in writing before or at the start of representation.

Model Rules 1.5: Ethical Boundaries

The American Bar Association's Model Rule of Professional Conduct 1.5 governs attorney fees in all jurisdictions, with state variations. Its requirements for contingency fees are specific:

• The agreement must be in writing, signed by the client before or at the start of representation.
• It must state the method by which the fee is determined, including the percentage that will accrue in the event of settlement, trial, or appeal.
• It must state whether expenses are to be deducted before or after the fee is calculated.
• Upon conclusion, the attorney must provide a written statement showing the outcome and, if there is a recovery, showing the remittance to the client and the method of determination.

Contingency fees are prohibited under Model Rule 1.5(d) in two categories of representation: domestic relations cases (divorce, custody, alimony — because contingency creates incentive to prolong proceedings) and criminal defense cases (no financial recovery from which a percentage could be taken). A few states — California, Texas — have developed their own variations on these prohibitions.

Alternative Fee Arrangements

Hourly billing, contingency fees, and hybrid arrangements compete for different client contexts:

Medical Lien Priority at Settlement

A personal injury recovery is not simply deposited into the client's bank account. Medical providers, health insurers, and government programs hold liens against the settlement that must be resolved before the client receives their net share. Lien priority — who gets paid first and how much — is one of the most technically complex aspects of settlement administration.

Medicare's conditional payment claims carry federal law force under the Medicare Secondary Payer Act (42 U.S.C. §1395y). Medicare has the right to recover its conditional payments from any settlement proceeds, and failure to satisfy Medicare's lien exposes both the client and the attorney to double damages liability. The attorney has a legal obligation to protect Medicare's interest and may be personally liable if they distribute settlement proceeds while knowing Medicare's lien remains unsatisfied.

Medicaid liens are governed by state law within federal parameters set by the Supreme Court's 2013 Wos v. E.M.A. decision, which held that states cannot impose irrebuttable presumptions allocating settlement proceeds to Medicaid. Most settlements therefore require a formal allocation between medical damages (subject to the lien) and non-medical damages like pain and suffering (not subject to the lien).
