Key Takeaways
- Most Chicago injury lawyers work on a contingency fee basis, with no upfront fee.
- Case costs are separate from the fee, and your agreement must explain them.
- Illinois caps medical malpractice fees at one-third, most workers’ compensation fees at 20%, and liens covered by the Health Care Services Lien Act at 40%.
- You can change lawyers, and a discharged lawyer is owed only the reasonable value of the work.
Most Chicago personal injury lawyers charge nothing upfront and take a percentage of the recovery, often about one-third. If you are already juggling medical bills and missed paychecks after an injury, that structure matters. You can get legal help without writing a check you cannot afford.
At Conboy Law, we handle injury cases on a contingency fee basis, and we put every fee term in writing before you sign. The true cost to hire a personal injury lawyer in Chicago depends on the fee percentage, the case costs, and any liens on your recovery.

How Much Does a Personal Injury Lawyer Cost in Chicago?
Most personal injury lawyers in Chicago charge a contingency fee, which is a percentage of any settlement or verdict, instead of hourly bills. Many agreements set that percentage around 33%, and some increase it if the case goes to trial. Under Illinois Rule of Professional Conduct 1.5, every fee must be reasonable, including contingent fees.
What a Contingency Fee Covers
The fee pays for the legal work on your claim. That work can include investigating the incident, gathering medical records, negotiating with insurers, filing a lawsuit, and trying the case if needed. With a contingency fee, there is no retainer or hourly bill, and the fee comes out of the recovery.
Before you compare firms, learn how contingency fees work.
Why the Percentage Can Change at Each Stage
Illinois Rule 1.5 requires a contingent fee agreement to state the percentage that applies if the case settles, goes to trial, or goes to appeal. Some agreements use a higher percentage at later stages because a trial takes more time and expense.
You can also compare what Illinois car accident lawyers typically charge at each stage.
Attorney Fees vs. Case Costs in a Chicago Injury Claim
The attorney fee pays for legal work. Case costs are the out-of-pocket expenses needed to build and prove the claim. Common case costs include the following:
- Court filing and service fees, including fees in the Cook County Circuit Court’s Law Division, which hears personal injury claims over $30,000
- Fees for copies of medical records and bills
- Expert witness fees for doctors, engineers, or economists
- Deposition transcripts and court reporter charges
- Investigation costs, such as scene photos, video, and vehicle data
- Mediation fees and trial exhibits
Do You Pay Case Costs if You Lose?
Illinois Rule of Professional Conduct 1.8(e) allows a lawyer to advance court costs and litigation expenses, with repayment that may depend on the outcome. Rule 1.5 also requires your agreement to identify any expenses you must pay whether or not you win.
At Conboy Law, we advance all case-related costs and recover them only if your case produces a successful outcome. If the case does not succeed, you owe us nothing.
How Medical Liens Affect What You Take Home
Hospitals and doctors who treated you may place liens on your recovery. Under the Illinois Health Care Services Lien Act, all health care liens combined cannot exceed 40% of the settlement or verdict. Once liens reach that cap, health care professionals are limited to 20%, and providers such as hospitals are limited to 20%.
The same law limits attorney liens to 30% when health care liens reach 40%, unless a party appeals. Health insurers and Medicare may also have repayment rights under separate rules.
The Hidden Cost of Pre-Settlement Funding
Some injured people take a cash advance against their case. Under the Illinois Consumer Legal Funding Act, a funding company may charge up to 18% of the amount funded at the start of each 6-month period, for up to 42 months. It may also charge a document fee of up to $75.
If you repay a $5,000 advance after 11 months, two charges apply, totaling $1,800 before that fee.
What You Take Home: A Sample Chicago Settlement Breakdown
Every case is different. This hypothetical assumes a one-third fee calculated after case costs:
- Start with a $60,000 settlement.
- Subtract $3,000 in case costs, leaving $57,000.
- Subtract the one-third attorney fee of $19,000.
- Subtract a $9,000 hospital lien, well under the $24,000 limit the 40% lien cap would allow.
- Your net recovery is $29,000.
If the agreement calculates the fee before costs, the fee would be $20,000, and you would receive $28,000. Rule 1.5 also requires your lawyer to give you a written closing statement showing the outcome, the amount sent to you, and how it was calculated.
Illinois Laws That Limit Personal Injury Attorney Fees
Several Illinois rules control how injury lawyers charge and what they can collect.
Contingent Fee Agreements Must Be in Writing
Under Rule 1.5(d)(2), a contingent fee agreement must meet the following requirements:
- Be in writing and signed by you
- State the percentage that applies at settlement, trial, and appeal
- List the litigation and other expenses deducted from the recovery
- Say whether those expenses come out before or after the fee is calculated
- Identify any expenses you owe whether or not you win
Medical Malpractice Fees Are Capped at One-Third
Under 735 ILCS 5/2-1114, the total contingent fee in a medical malpractice action cannot exceed 33 1/3% of all sums recovered. This flat cap has applied since Public Act 97-1145 took effect on January 18, 2013.
If future damages are paid in installments, they are converted to a lump-sum value before the fee is calculated. If a hospital or doctor harmed you, a Chicago medical malpractice lawyer can explain how the cap applies to your claim.
Workers’ Compensation Fees Are Capped at 20%
Section 16a of the Illinois Workers’ Compensation Act generally limits attorney fees to 20% of the compensation recovered, unless the Illinois Workers’ Compensation Commission approves more after a hearing. Fee contracts must use forms the Commission prescribes. Lawyers also cannot collect a fee on undisputed medical expenses.
Referral Fees Require Your Written Consent
Lawyers at different firms sometimes share a fee on a referred case. Under Rule 1.5(f), that split is allowed only when these conditions are met:
- The division matches each lawyer’s work, or both lawyers accept joint financial responsibility for the case
- You agree to the arrangement, including each lawyer’s share, and the agreement is confirmed in writing
- The total fee remains reasonable
What Happens to the Fee if You Switch Lawyers?
Rule 1.5(c) prohibits any agreement that restricts your right to end the representation. In In re Estate of Callahan, the Illinois Supreme Court held that a discharged contingent fee lawyer is limited to the reasonable value of services provided, not the contract percentage.
The prior lawyer may still claim a lien on your recovery. Before you switch, ask how any earlier fee will be resolved.
Questions to Ask Before You Sign a Fee Agreement in Chicago
A few direct questions can prevent surprises at the end of your case:
- What percentage applies if the case settles, goes to trial, or is appealed?
- Are case costs deducted before or after the fee is calculated?
- Do I owe any costs if there is no recovery?
- Who negotiates medical liens, and is there an extra charge for it?
- Will another lawyer or firm share the fee?

It can. Illinois requires a contingent fee agreement to state the percentage for settlement, trial, and appeal. Read the stage terms before you sign so you know what applies at each point.
Most Illinois personal injury lawsuits must be filed within 2 years after the cause of action accrues under 735 ILCS 5/13-202. Claims against a local public entity, such as the City of Chicago or the Chicago Transit Authority, generally carry a 1-year deadline under 745 ILCS 10/8-101. An early case evaluation leaves time to investigate before either deadline.
