How Do Lawyer Fees Work? Contingency, Hourly, Flat, and Retainer

How do lawyer fees work? In most cases you’ll pay one of four ways: a percentage of what you recover (contingency), an hourly rate for time spent, a flat fee for a defined task, or an upfront deposit called a retainer that the lawyer draws against as work is done. Which one applies depends mostly on the type of case. Personal injury runs on contingency. Criminal defense, custody, and business disputes usually bill by the hour. A simple will or an uncontested divorce typically comes with a flat price. Understanding the model before you sign the fee agreement is the difference between a predictable bill and an unpleasant one.

Contingency Fees

Under a contingency arrangement, the lawyer gets paid only if you win. The fee is a percentage of whatever you recover through settlement or judgment, commonly around 33% for cases that settle before a lawsuit is filed and climbing to 40% once the case moves into active litigation or heads to trial. If nothing is recovered, you owe nothing for the lawyer’s time.

Most agreements use a sliding scale that raises the percentage as the case progresses through more expensive stages. Trial demands far more of the lawyer’s time and carries more financial risk for the firm, so the share goes up to reflect that investment. Personal injury, workers’ compensation, and employment claims are the most common contingency practices.

The ABA Model Rules require every contingency agreement to be in writing and signed by the client. It has to spell out the percentage at each stage—settlement, trial, appeal—and explain whether expenses come off the recovery before or after the percentage is calculated.¹

That before-or-after distinction matters more than most people realize. Suppose your case settles for $100,000 with $10,000 in expenses and a one-third fee. If the lawyer’s cut is calculated first, you receive about $56,667. If expenses come off first, you receive $60,000. Four thousand dollars can hinge on a single clause, so confirm which method applies before you sign.

Where Contingency Fees Are Not Allowed

Lawyers cannot take a contingency fee in criminal defense cases, or in divorce and custody matters where the fee depends on securing a divorce or on the size of alimony or property settlement.¹ If someone offers you a contingency deal for either, treat that as a red flag about the lawyer’s ethics.

Federal Fee Caps

Some federal claims cap fees by statute. Under the Federal Tort Claims Act, fees cannot exceed 25% of a court judgment or settlement, or 20% of an award resolved administratively before litigation. A lawyer who exceeds those caps faces a fine of up to $2,000 and up to a year in prison.²

Hourly Rates

When the outcome isn’t a money judgment, most lawyers bill by the hour. You pay for time spent, usually tracked in six-minute increments (tenths of an hour). Criminal defense, custody disputes, business litigation, and estate planning are the most common hourly practices.

Rates vary enormously. A junior associate at a small-market firm might charge $150 to $250 per hour, while a senior partner at a large firm in a major city could bill $500 to $1,000 or more. Different tasks within the same case may bill at different rates: a paralegal’s research time costs less than the lead attorney’s courtroom hours.

The drawback is unpredictability. A case expected to take 20 hours can easily take 50, and you won’t know the final number until the work is done. Ask early for an estimate of total hours and an honest assessment of what could push the number up. A good lawyer will give you a range rather than dodge the question.

Flat Fees

For predictable, well-defined work, many lawyers charge a single flat fee. Drafting a basic will, handling an uncontested divorce, forming an LLC, or representing you on a routine traffic ticket are all services with a scope clear enough to price upfront.

The appeal is certainty: you know what you’ll pay regardless of how many hours the work takes. The risk is that flat fees rarely cover unexpected complications. If your “simple” divorce turns contested, the flat fee agreement probably won’t apply anymore, and you’ll shift to hourly billing. Read the agreement to see what’s included and what triggers additional charges.

Retainers and Trust Accounts

A retainer is an upfront deposit that secures the lawyer’s services. The money goes into a client trust account, which is legally separate from the firm’s own funds, and the lawyer draws against it as work is performed. You’ll receive itemized invoices showing what was done, the time spent, and the amount deducted from your balance.

Lawyers have a fiduciary obligation to keep those funds segregated. They cannot treat the deposit as income until they’ve earned it by performing work. Mishandling trust accounts is one of the most common reasons lawyers face discipline, which is why every state’s conduct rules require separate accounting.

When the retainer runs low, the lawyer will ask you to replenish it. If money remains when the case ends, the lawyer must return the unused portion.³

Some agreements use an “evergreen” retainer, which requires you to maintain a minimum balance at all times. Instead of waiting for the account to hit zero, you top it up whenever it drops below a set threshold, say $2,000. The agreement should specify the minimum balance, the timeframe for replenishment, and what happens if you don’t replenish. Typically the firm stops work until you do.

Costs the Fee Doesn’t Cover

Win or lose, a lawsuit generates out-of-pocket costs separate from the lawyer’s fee. These are your responsibility regardless of the billing structure, and they can accumulate faster than most clients expect.

Court filing fees. Every lawsuit begins with a filing fee. Federal district courts charge a uniform amount for civil complaints; state court fees vary based on case type and dollar amount at stake.
Expert witness fees. Specialists who provide reports or testify can charge hundreds to thousands of dollars per hour, depending on the field and complexity.
Deposition costs. Taking sworn testimony outside of court requires a certified court reporter, and transcripts are billed by the page.
Service of process. Delivering documents to the opposing party through a private process server typically runs $40 to $100, with rush delivery or hard-to-locate parties costing more.
Miscellaneous expenses. Copying, postage, travel, investigation, and medical record retrieval all show up on your invoice.

In contingency cases, the agreement will specify how costs are handled. Some lawyers advance all costs and deduct them from any recovery. Others require you to pay as expenses arise. Either way, you’re on the hook for these charges even if you lose. This is one of the most commonly misunderstood parts of contingency arrangements, so ask about it explicitly.

What to Confirm Before Signing the Fee Agreement

Before any work begins, you should have a written fee agreement. Many states require one when the expected total cost exceeds a certain dollar threshold. For contingency cases, a signed written agreement is mandatory under the ABA Model Rules.¹ Even where writing isn’t legally required, it eliminates the “I thought we agreed to…” arguments that derail attorney-client relationships.

Before you sign, confirm these points:

How the fee is calculated. For contingency cases, whether the percentage comes off before or after expenses.
Who owes costs if you lose. Whether you owe filing fees, expert fees, and deposition transcripts even without a recovery.
Interest on unpaid balances. Whether the lawyer can charge interest on overdue invoices, and at what rate.
How the fee changes by stage. What happens if the case goes to trial, to appeal, or settles early.
Retainer refund. What happens to any remaining balance when the representation ends.

Taxes on a Settlement or Judgment

How your recovery is taxed depends on the type of claim, and the rules can turn a win into an expensive surprise.

Compensatory damages for personal physical injuries or physical sickness are excluded from gross income.⁴ That covers most personal injury settlements: car accidents, medical malpractice, workplace injuries. Punitive damages are always taxable, even when they arise from a physical injury claim.⁵

If your claim is based on emotional distress without a physical injury, such as harassment, defamation, or breach of contract, the settlement is taxable income. The payer will report the full amount to the IRS on Form 1099-MISC.⁵

The trap: when your settlement is taxable, the IRS treats the entire amount as your gross income, including the portion your lawyer took as a contingency fee. The Supreme Court confirmed this in Commissioner v. Banks.⁶ Settle an employment claim for $200,000 with a $66,000 contingency fee and you report $200,000 in income. Congress carved out an above-the-line deduction for attorney fees and court costs in employment discrimination, whistleblower, and certain other federal claims, capped at the amount you included in income from the claim.⁷ Outside those categories, there is currently no equivalent deduction, and you can owe tax on money you never received. If your case involves a taxable settlement, talk to a tax professional before the check arrives.

Firing Your Lawyer Mid-Case

You always have the right to fire your lawyer. The ABA Model Rules make this absolute: a client can discharge counsel at any time, with or without cause. On termination, the lawyer must take reasonable steps to protect your interests, surrender your files, and refund any unearned portion of a retainer.³

The money gets more complicated on contingency. A discharged contingency lawyer is typically entitled to the reasonable value of services already performed, a concept called “quantum meruit.” The original contingency percentage generally serves as a ceiling on what the fired lawyer can recover, and the fee usually remains contingent, meaning the old lawyer collects nothing unless you eventually win. In practice, your new lawyer and your old lawyer end up splitting the single contingency fee based on the work each performed. Switching doesn’t reduce the total fee. It divides it.

Disputing a Bill

If you believe your lawyer overcharged you, most state bar associations run fee arbitration programs. Under the ABA’s model framework, the process is voluntary for the client but mandatory for the lawyer once the client files a petition.⁸ While arbitration is pending, the lawyer must stop all non-judicial collection activity on the disputed amount.

The arbitration decision becomes binding unless either party requests a trial within 30 days after the decision is served. The ABA model rules set the filing deadline at four years after the attorney-client relationship ends or after the final bill, whichever is later.⁸

An unreasonable fee is also an ethics violation. The ABA Model Rules prohibit any unreasonable fee, and the reasonableness factors include time and labor required, difficulty of the case, the lawyer’s experience, and the results obtained.¹ A disciplinary complaint to your state bar is an option alongside fee arbitration, particularly if the billing suggests dishonesty rather than a disagreement over value.
