Why do lawyers take 33 percent of an injury recovery? The short answer is that a one-third contingency fee prices in the risk, time and money a lawyer puts up before anyone knows whether the case will pay. No national law sets that number. Instead, it is a market convention that some states have written into their own rules, and it moves when the risk moves.
This guide stays on the why. For the mechanics of how a contingency fee gets calculated and paid out, our guide on how contingency fees work walks through it step by step. Here, the goal is to explain the reasoning behind the percentage, so the figure in your agreement makes sense before you sign it.
Why do lawyers take 33 percent and not some other share?
The one-third contingency fee is a convention, not a federal rule, and no official source sets a national standard percentage. That point matters, because many people assume the law fixes the number. It does not — lawyers and clients agree on the price, within limits each state sets.
Still, lawyers take 33 percent so often for a few practical reasons:
- It is easy to explain. A client can picture one share for the lawyer and two for themselves.
- It balances risk across many cases. A firm wins some cases, loses others, and needs the winners to cover the losers.
- Some states anchor to it. Michigan, for example, caps personal injury contingency fees at one-third, and Florida starts its presumptive scale at 33⅓%.
In other words, the 33 percent contingency fee survives because it works for both sides often enough. Yet it is a starting point, not a law of nature.
The American rule: why the fee comes out of the recovery
In US courts, each side normally pays its own lawyer, so an injured person usually cannot make the other side cover their legal fees. The Supreme Court confirmed this “American rule” in Alyeska Pipeline Service Co. v. Wilderness Society (1975). It held that, absent a statute or an enforceable contract, litigants pay their own attorneys’ fees.
That rule shapes the whole fee system. Because the defendant will not pay the fee on top of the recovery, the fee has to come out of it. As a result, a contingency fee is a share of what the client receives, not an extra charge to the other side.
It also explains why the percentage feels large. No one pays the lawyer by the hour, and nobody else will cover the bill. So the share has to fund the work on the cases that win and absorb the cases that lose.
The risk lawyers take on behind the 33 percent
A contingency lawyer earns nothing unless the case produces a recovery, which means every hour on a losing case goes unpaid. The 33 percent share is how many lawyers take that gamble into account.
Consider what the lawyer cannot know at the start:
- Whether the facts will hold up once the records and witnesses come in.
- Whether the other side will dispute fault or the injuries.
- How long the case will take, from a few months to several years.
- Whether the other side has insurance or assets to pay a judgment.
The ABA Model Rules recognise this risk directly. ABA Model Rule 1.5(a) lists eight factors for judging whether a fee is reasonable. One of them asks simply whether the fee is fixed or contingent. In plain terms, a fee that might turn out to be zero can fairly run higher than a guaranteed one.
Most states base their ethics rules on the ABA Model Rules, though each state adopts its own version. So check how your state words it.
Time the lawyer gives up
When lawyers take a 33 percent case on contingency, they also turn down other work, and the percentage has to cover that lost opportunity. A lawyer who commits months to one injury claim cannot spend those months on paying hourly matters.
Rule 1.5(a) treats this as a fair consideration too. Another of its eight factors is the likelihood, if apparent to the client, that taking the case will keep the lawyer from other work. Therefore, a demanding case that ties up a small firm can justify a fuller share than a quick, simple one.
Several other factors on the same list point the same way:
- the time and labor the case requires and the difficulty of the questions;
- the skill the work demands;
- the experience, reputation and ability of the lawyer; and
- the fee lawyers customarily charge in the area for similar services.
Costs the firm advances
On top of time, many contingency lawyers pay the case costs as they go, which adds a second layer of risk to the percentage. Costs can include filing fees, medical records, expert reviews and depositions.
The ethics rules allow this. Under ABA Model Rule 1.8(e)(1), a lawyer may advance court costs and litigation expenses, and repayment may depend on the outcome. That means some lawyers agree to absorb those costs if the case loses.
However, that is not automatic. Whether the client owes costs after a loss depends on the agreement itself. Rule 1.5(c) requires a contingency agreement to state which expenses come out of a recovery. It must also say whether they come out before or after the lawyer calculates the fee. On top of that, it must flag any expenses the client owes win or lose. Our guide to contingency fee agreements covers that fine print.
Either way, the firm loses any money it fronts on a losing case. That is part of why lawyers take 33 percent on the cases that do win: those fees keep the system running.
Why is the contingency fee 40 percent in some agreements?
A higher contingency fee percentage usually reflects more work and more risk at a later stage of the case, especially once a lawsuit starts. Many agreements step up the percentage as the case moves forward.
Rule 1.5(c) expects this. It says a contingency agreement must state the percentage or percentages that apply at settlement, at trial or on appeal. So one agreement can lawfully contain more than one number.
Florida’s rule shows how a stepped scale works. Under Rule 4-1.5(f)(4)(B) of the Rules Regulating The Florida Bar, a tort fee above certain levels is presumed clearly excessive:
- 33⅓% on the first tier of a recovery if the case resolves before the defendant answers or anyone demands arbitration;
- 40% on that first tier after the answer, through judgment;
- lower percentages on the larger portions of a recovery; and
- an extra 5% for an appeal or post-judgment collection.
That is one state’s rule, not a national norm. Even so, it shows the logic. Once the other side answers, the case usually needs discovery, motions and possibly trial preparation. The 40 percent figure prices that added work.
Sliding scales and caps: when the percentage rises or falls
Risk is not the only force on the contingency fee percentage; in some situations, law and court rules push it down. The table below shows how a few confirmed rules set or limit the share.
| Rule | What it covers | How it limits the percentage |
|---|---|---|
| Michigan Court Rule 8.121 | Personal injury and wrongful death | Caps the fee at one-third, calculated on the net recovery after disbursements |
| Florida Bar Rule 4-1.5(f)(4)(B) | Tort cases | Presumptive limits of 33⅓% or 40% on the first tier, lower on larger tiers |
| Federal Tort Claims Act, 28 U.S.C. § 2678 | Claims against the US government | 25% of a judgment or post-suit settlement; 20% of an administrative settlement |
| New Jersey court rule | Tort cases | Caps contingent fees on a sliding scale |
Michigan’s limit is strict. The State Bar of Michigan’s ethics opinion RI-122 quotes the court rule and treats anything above it as a clearly excessive fee, even if the client agreed. Similarly, the federal cap on claims against the government sits below one-third. That reflects a policy choice by Congress, not a judgment about the work.
The pattern across these rules is consistent. Bigger recoveries often carry lower percentages on the upper portions, and earlier resolution often carries a lower rate. Meanwhile, later-stage work often carries a higher one.
Do lawyers take 33 percent no matter what? Negotiating the share
Not always — the one-third contingency fee is a price, not a fixed rate, though the room to negotiate depends on the case and the lawyer. The reasonableness factors in Rule 1.5(a) cut both ways.
A case with clear fault, strong records and little expected work carries less risk. In that situation, some people ask whether the lawyer will accept a lower percentage, or a lower rate if the case settles early. On the other hand, a hard case with disputed liability may leave little room to move.
Useful questions to ask the lawyer at the consultation include:
- What percentage applies if the case settles before anyone files a lawsuit?
- Does the percentage change if you file suit, if the case goes to trial, or if there is an appeal?
- Do costs come out before or after you calculate the fee?
- Will I owe any costs if there is no recovery?
- What about this case makes you price it the way you have?
The last question is the most revealing. A lawyer who can explain why the percentage fits the risk is giving you the reasoning this article describes. For more on what to ask, see our list of questions to ask a personal injury attorney. Also, the first offer in a case is rarely the last; our guide on whether the first settlement offer is negotiable explains why.
Whatever you agree, Rule 1.5(c) requires a contingency agreement in writing, signed by the client. So any change belongs in that signed document.
The bottom line
So, why do lawyers take 33 percent? A contingency lawyer works for free unless the case succeeds, gives up other work, and often fronts the costs. The one-third share is how many lawyers take that combined risk into account. Yet no national law fixes it. Some states cap it, some use stepped scales that rise to 40% after the defendant answers, and federal claims carry lower limits.
The number in any one agreement should match the risk in that case. Many people ask the lawyer to explain it, check how costs interact with the fee, and make sure the signed agreement spells out every percentage.
Frequently asked questions
A one-third contingency fee prices in the risk that the lawyer gets nothing if the case loses, the other work the lawyer turns down, and the costs the firm often advances. It is a market convention, not a national law.
No national law sets it. Some states limit contingency fees by rule — Michigan caps personal injury fees at one-third, for example — but in most places the percentage is agreed between lawyer and client within state ethics limits.
Many agreements raise the percentage once a lawsuit is filed and answered, because the case then needs discovery, motions and possibly trial preparation. Florida’s rule, for instance, allows a presumptive 40% on the first tier of a recovery after an answer is filed.
Often it is, depending on the case and the lawyer. A case with clear fault and little expected work carries less risk, so some people ask about a lower percentage or a lower rate for an early settlement.
A contingency lawyer is paid only if there is a recovery, so every hour on a losing case goes unpaid. ABA Model Rule 1.5(a) lists whether a fee is fixed or contingent as one of eight factors in judging whether a fee is reasonable.
Under the American rule, each side normally pays its own lawyer unless a statute or an enforceable contract says otherwise. That is why a contingency fee comes out of the recovery rather than being added on top.
Many do. ABA Model Rule 1.8(e)(1) lets a lawyer advance court costs and litigation expenses, with repayment depending on the outcome, but whether you owe costs after a loss depends on your written agreement.
Yes. Claims against the US government under the Federal Tort Claims Act are capped at 25% of a judgment or post-suit settlement and 20% of an administrative settlement, and sliding scales in some states reduce the percentage on larger recoveries.
Yes. Under ABA Model Rule 1.5(c), a contingency agreement must be in writing, signed by the client, and must state the percentage that applies at settlement, trial or appeal.
Many people ask what percentage applies at each stage, whether costs come out before or after the fee, whether they owe costs if the case loses, and why the lawyer priced the case the way they did.
