Contingency Fees in Illinois
Standard Contingency Rate: 33-40%
Standard 33% pre-litigation, 40% post-filing. Medical malpractice fees subject to court approval.
Contingency fee arrangements are commonly used in Illinois for personal injury cases, medical malpractice claims, and workers' compensation disputes. Under a contingency agreement, the attorney advances all case costs and only collects a fee if they successfully recover compensation on your behalf. If you lose, you owe nothing in attorney fees, though you may still be responsible for certain court costs depending on your agreement.
When evaluating a contingency fee offer from a Illinois attorney, ask about: what percentage they charge, whether the percentage changes after filing a lawsuit or going to trial, how case expenses are deducted (before or after the fee calculation), and what happens if you need to change attorneys mid-case.
