Lawyers who get paid only if you win are working on a contingency fee: they collect nothing upfront and nothing at all if the case produces no recovery, taking instead a percentage of whatever money you receive. That percentage usually sits between 33% and 40%, with the exact number shaped by how far the case has to go and by what the written agreement says about expenses. Those agreement details — not the headline percentage — are what determine your take-home.
How the Arrangement Works
You pay nothing when you hire the lawyer and nothing while the case is pending. The lawyer’s compensation comes entirely from the money recovered on your behalf. If there’s no recovery, you owe no attorney fee. Because the lawyer is betting their time on the case, most are selective about which ones they take; weak claims or small potential recoveries often get turned down.
This is the opposite of hourly billing, where you pay for every hour whether you win or lose. A complex case under hourly billing can run up tens of thousands in fees before any money comes back to you. Contingency removes that risk, but introduces its own trade-offs around how costs and percentages are structured.
Professional ethics rules require every contingency fee agreement to be in writing and signed by the client. It must spell out the percentage, how that percentage changes at different stages, which expenses you’re responsible for, and whether those expenses are deducted before or after the lawyer’s cut is calculated.1American Bar Association. Model Rules of Professional Conduct – Rule 1.5 Fees Read every clause before you sign. A single line can shift thousands of dollars.
What Percentage the Lawyer Takes
One-third is the typical starting point, but many lawyers use a tiered structure that climbs as the case demands more work:
- Pre-litigation settlement (25%–33%): a demand letter or negotiation that resolves the case before any lawsuit is filed.
- After filing a lawsuit (33%–40%): once the complaint is filed and the case enters discovery, depositions, and motion practice.
- Trial or appeal (40% or higher): some agreements allow 40% to 45% if the case goes to verdict or requires post-trial appeals.
Across personal injury contingency cases as a whole, percentages generally fall between 20% and 50%, though numbers outside the 33%–40% band are less common.2Legal Information Institute. Contingency Fee
Gross Recovery vs. Net Recovery
Whether the percentage is calculated on the gross recovery or the net recovery (after case expenses are deducted) changes your bottom line. Take a $100,000 settlement with $10,000 in expenses and a one-third fee:
- Fee on gross: the lawyer takes one-third of $100,000 ($33,333). The $10,000 in expenses then comes out of your remaining $66,667, leaving you with $56,667.
- Fee on net: expenses of $10,000 are deducted first, leaving $90,000. The lawyer takes one-third of $90,000 ($30,000), leaving you with $60,000.
That one clause moves $3,333 in this example, and the gap widens with larger recoveries and higher expenses. Check which method your agreement uses, and push to negotiate if it’s gross.
What “No Fee If You Lose” Actually Covers
The promise covers the lawyer’s professional fee. It does not automatically cover the out-of-pocket costs of running the case. These are two separate buckets, and the mix-up is one of the most common misunderstandings.
Case costs can include court filing fees, deposition transcripts, medical records, expert witness fees, postage, and copying. In medical malpractice especially, expert witness fees alone can reach the thousands. Your lawyer will usually advance these costs as the case progresses. If you win, they’re deducted from the recovery before percentages are calculated.
The question is what happens to those advanced costs if you lose. Ethics rules allow lawyers to make repayment of advanced litigation expenses contingent on recovery.3American Bar Association. Model Rules of Professional Conduct – Rule 1.8 Current Clients Specific Rules Many lawyers do exactly that, meaning if you lose, you owe nothing at all. But some agreements require you to reimburse advanced costs no matter the outcome. Ask directly: “If we lose, do I owe anything?” Get the answer in writing.
Cases That Qualify, and Two That Don’t
Contingency fees show up almost exclusively in civil cases where the goal is monetary compensation. The common case types include:
- Personal injury — car accidents, slip-and-fall, product liability, wrongful death.
- Medical malpractice — expensive to litigate, but recoveries are substantial.
- Workers’ compensation, particularly denied or disputed claims.4American Bar Association. When You Need a Lawyer – Legal Fees and Expenses
- Employment discrimination, wrongful termination, and unpaid wage claims.
- Consumer class actions over defective products or deceptive practices.
Two case types are off-limits in most states. A lawyer cannot charge a contingency fee to defend a criminal case, and cannot charge one in a divorce or custody matter where the fee depends on whether the divorce is granted or on the amount of alimony, child support, or property the client receives.1American Bar Association. Model Rules of Professional Conduct – Rule 1.5 Fees For either, expect hourly billing or a flat fee instead.
State Caps on Medical Malpractice Fees
About a dozen states cap contingency fees in medical malpractice cases by statute. The caps often use a sliding scale tied to the size of the recovery: the percentage starts at 30%–40% on the first portion of the award and steps down to 10%–25% on amounts above set thresholds. A lawyer in a capped state cannot legally charge more than the limit even if the written agreement says otherwise. Outside medical malpractice, fee caps are uncommon, and the percentage is a matter of negotiation.
How Your Settlement Is Taxed
Tax treatment depends on why you received the money. Getting it wrong can produce an unexpected five-figure bill.
If the settlement compensates you for a physical injury or physical sickness, the entire amount is excluded from your taxable income, including the portion that goes to your lawyer. This covers most personal injury and medical malpractice recoveries.5Office of the Law Revision Counsel. 26 USC 104 – Compensation for Injuries or Sickness Punitive damages are taxable even if they arise from a physical injury claim. Emotional distress damages are also taxable unless they reimburse you for actual medical treatment.
Settlements for employment discrimination, breach of contract, defamation, and other non-physical claims are fully taxable as ordinary income. Here’s the trap: the IRS taxes you on the entire settlement, including the portion your lawyer takes. The Supreme Court confirmed this in 2005, so if you recover $500,000 and your lawyer takes $165,000, you owe income tax on $500,000.6Justia US Supreme Court. Commissioner v. Banks, 543 US 426 (2005)
Congress carved out relief for certain case types. If your settlement involves unlawful discrimination (race, sex, age, disability) or a whistleblower award, you can deduct the attorney fees from your gross income, meaning tax applies only to the net you actually receive. This deduction is available whether you itemize or not. For other taxable settlements, no equivalent deduction exists. If your case falls in that gap, talk to a tax professional before finalizing any deal; restructuring the settlement can sometimes reduce the hit.
If You Need to Fire Your Lawyer
You can fire a contingency lawyer at any time, for any reason. But ending the relationship doesn’t mean the lawyer walks away empty-handed. A discharged contingency lawyer is entitled to compensation for the reasonable value of work performed up to that point, under a concept called quantum meruit.
That payment doesn’t come due immediately. The former lawyer’s right to be paid ripens only when the contingency actually occurs, meaning when you eventually settle or win. At that point, the original lawyer’s share is calculated based on the proportion of total work performed, and it comes out of the overall contingency fee rather than stacking on top of what you’d owe a new lawyer.
To protect that interest, a discharged lawyer can file a charging lien against your eventual recovery. The settlement check will then list the former lawyer as a payee, and the fee dispute has to be resolved before you see the money. A legitimate reason to switch — a lawyer who stops communicating or misses deadlines — is worth the hassle. Switching out of impatience with the pace of litigation usually isn’t.
Questions to Ask Before You Sign
Most contingency lawyers offer a free initial consultation. Use it to evaluate the lawyer as much as to tell your story. Ask:
- What’s your fee percentage, and does it increase at different stages? Get the full tiered structure, not just the starting number.
- Is your fee calculated on gross or net recovery?
- What happens to advanced costs if we lose? Clarify whether you owe reimbursement regardless of outcome.
- How many cases like mine have you handled, and what were the results?
- Who will actually work on my case day to day?
Walk away from a lawyer who pressures you to sign immediately, quotes a percentage above the normal range without a clear reason, or can’t explain how expenses will be handled. A good contingency lawyer has answered these questions hundreds of times and has nothing to hide.
