Birth Injury Lawsuit in Illinois

Illinois birth injury lawsuits are filed in Circuit Court in the county where the act or omission occurred. Cook County (Chicago) dominates the obstetric malpractice docket, with DuPage, Lake, Will, and Kane counties handling suburban cases. Illinois requires plaintiffs to attach an affidavit (735 ILCS 5/2-622) stating that a licensed health professional has reviewed the case and found a reasonable and meritorious cause for filing. This affidavit must be filed within 90 days of the complaint if not attached at filing.

Illinois medical malpractice claims must be filed within two years of the date the claimant knew or reasonably should have known of the injury and its malpractice cause, subject to an absolute eight-year repose period from the act or omission (735 ILCS 5/13-212). For minors, Illinois tolls the limitations period for the minority period—the two-year clock does not begin until the child turns 18, giving families until age 20 to file. The eight-year repose period is not tolled for minors, which can create filing deadlines before age 18 for injuries with a clear date.

Illinois has no enforceable cap on medical malpractice damages. The Illinois Supreme Court struck down the legislature's $500,000/$1,000,000 non-economic damages caps in Lebron v. Gottlieb Memorial Hospital (2010) as a violation of the separation of powers doctrine. Illinois juries in Cook County have historically returned substantial verdicts in catastrophic birth injury cases, with several judgments exceeding $20–40 million in severe cerebral palsy and HIE cases when lifetime care costs are fully presented.

Illinois obstetric malpractice litigation frequently targets major Chicago-area health systems—Northwestern Memorial, Rush University Medical Center, Advocate Health, and University of Chicago Medicine—as well as community hospitals in the collar counties. Common case theories include failure to recognize prolonged variable or late decelerations, delayed emergency C-section in cases of placental abruption or umbilical cord prolapse, and improper administration of oxytocin leading to uterine hyperstimulation and fetal hypoxia.
