What a lawyer does
What a Chicago car accident lawyer does for you.
After a crash you deal with doctors, insurers and deadlines at the same time. Here is the work a lawyer takes off your plate.
-
Investigates the crash
Gets the police report, photos and witness accounts to show how the collision happened.
-
Documents your losses
Medical bills, lost pay, pain and suffering. Illinois has no cap on compensatory damages.
-
Deals with the insurers
Handles calls and offers from the other driver’s insurer, and claims on your own UM coverage.
-
Pushes back on blame
Under the 51% rule every point of fault put on you reduces what you can recover.
-
Tracks your deadlines
2 years for most injury suits; 1 year against the City, plus a 6-month notice for the CTA.
-
Goes to court if needed
Files suit in the Cook County Circuit Court’s Law Division if a fair offer doesn’t come.

Illinois fault rule
Partly to blame? The 51% rule, explained.
Illinois uses modified comparative fault (735 ILCS 5/2-1116). Fault is split between the people involved, and your share decides what you can recover.
-
1
Fault is split in percentages
Each driver, and sometimes a pedestrian or cyclist, gets a share of the blame.
-
2
50% or less: reduced recovery
Your damages are cut in proportion to your own share of fault.
-
3
More than 50%: no recovery
If you are found more at fault than not, you recover nothing.

51% rule · worked example
illustrative
The other driver says I was partly at fault. Can I still recover anything?
Yes, if your share is 50% or less. Your damages are reduced by your share:
| Your fault | Damages | You recover |
|---|---|---|
| 0% | $100,000 | $100,000 |
| 20% | $100,000 | $80,000 |
| 50% | $100,000 | $50,000 |
| 51% | $100,000 | $0 |

-
03
The claim
Evidence, medical records and losses go into a claim with the at-fault driver’s insurer.
-
04
Resolution
The claim settles, or a lawsuit is filed, within 2 years in most injury cases.
What it costs
How lawyer fees work in Illinois.
Car accident lawyers usually work on contingency: the fee comes out of the recovery, not your pocket upfront. These are not plans this site sells.
-
Common share
Contingency fee
33⅓%typical
A general US range is 25–40%, often rising toward 40% if a suit is filed or the case is tried. A range, not an Illinois rule.
- No statutory cap for auto cases in Illinois
- Paid only from a recovery
-
Expenses
Case costs
Varies
Records, filing and expert costs. Your agreement must say whether they come out before or after the fee.
- Ask for a written estimate
- Ask which costs you owe if you lose
-
Required
Written agreement
Signed
Illinois RPC 1.5(c): a contingency fee agreement must be in writing and signed by you before work goes ahead.
- Percent for settlement, trial and appeal
- How expenses are handled
Your situation
Situations that change the rules.
Most claims follow the 2-year deadline and the 51% rule. These situations add a twist worth knowing early.
-
CTA or City vehicle
Shorter clocks apply
1 year to sue a local public entity. The CTA also requires written notice within 6 months.
-
Uninsured driver
Your UM coverage may apply
Every Illinois auto policy must include uninsured-motorist injury coverage of at least 25/50.
-
Partly at fault
You may still recover
At 50% fault or less, damages are reduced by your share. Above 50%, you recover nothing.
-
Pedestrian or cyclist
Same deadlines apply
217 pedestrians were killed on Illinois roads in 2024 (IDOT). The 2-year deadline applies to you too.
-
Injured child
More time, usually
A minor can sue within 2 years after turning 18. Claims against a government body may not get that extra time.
-
Fatal crash
Wrongful death claims
A wrongful death action must be filed within 2 years of the date of death (740 ILCS 180/2).

Lawyer, referral or do it yourself?
Three common ways to handle a car accident claim in Chicago, compared by type, not by firm.
| Option | Upfront cost | Who values the claim | Deadlines & court | Best for |

FAQ
Chicago car accident lawyer questions.
Do I need a Chicago car accident lawyer after a crash?
Not always. If no one was hurt and only your car was damaged, many people handle the claim themselves. A lawyer helps most when you were injured, fault is disputed, the other driver was uninsured, or a CTA or City vehicle was involved.
How long do I have to file a car accident claim in Illinois?
In most cases 2 years from the injury to file a lawsuit (735 ILCS 5/13-202). Vehicle and property damage claims have 5 years, and wrongful death claims 2 years from the date of death.
What is the deadline for suing the CTA or the City of Chicago?
Shorter. A suit against a local public entity such as the City must be filed within 1 year (745 ILCS 10/8-101). For the CTA, a suit is due within 1 year and a written notice within 6 months (70 ILCS 3605/41). Speak to a lawyer quickly.
Do I have to report a car accident in Illinois?
Yes, to the police right away, by the fastest available means, if anyone is hurt or killed, or damage is over $1,500 (over $500 if a driver is uninsured). The old written motorist report to the state is no longer required for most drivers (Public Act 102-0560).
How do I get a Chicago police crash report?
Request it through the Chicago Police Department’s traffic crash reports page at chicagopolice.org, online, by mail or in person. A fee applies. If the Illinois State Police handled the crash, use the ISP crash report portal.
Can I recover if I was partly at fault?
Yes, if your share of the fault is 50% or less. Your damages are reduced by your share. If you are found more than 50% at fault, you recover nothing (735 ILCS 5/2-1116).
How much does a car accident lawyer cost in Chicago?
Most work on contingency. About 33⅓% is common, often rising to around 40% if a suit is filed or tried; that is a general range, not an Illinois rule. The agreement must be in writing and signed by you (Ill. RPC 1.5(c)).
What if the driver who hit me had no insurance?
Illinois policies must include uninsured-motorist coverage of at least $25,000 per person and $50,000 per accident, so your own policy may pay. The Secretary of State can also suspend an uninsured at-fault driver’s license.
Is there a cap on damages in Illinois car accident cases?
No. Illinois does not cap compensatory damages in personal injury cases. Punitive damages cannot be asked for in the first complaint; the court must allow them later (735 ILCS 5/2-604.1).
Does this site recommend a specific lawyer?
No. This site explains the rules and routes you to a free case review on a separate website. It does not refer or recommend any particular lawyer, and it is not a law firm.
