A carrier denied your business interruption claim, sent a reservation of rights letter on a liability suit, or is dragging out a property loss adjustment. The Chicago firms below handle first-party coverage, business interruption, D&O and E&O coverage, professional liability, third-party defense, and Section 155 bad-faith claims under Illinois law.

Chicago sits at the center of the U.S. commercial insurance market. The city is home to Aon (one of the world's two largest insurance brokers), CNA Financial, Kemper, Old Republic, RLI, Zurich North America's Schaumburg headquarters, and dozens of carriers and reinsurers running their Midwest operations out of the Loop. That density also produces a deep coverage bar — Chicago has more nationally ranked insurance coverage and bad-faith litigation lawyers than any U.S. city outside New York.
The most common reasons a Chicago business calls a coverage lawyer: a first-party property or business interruption claim has been denied or low-balled; a liability carrier has accepted defense under reservation of rights and the policyholder needs independent counsel; a D&O carrier has denied coverage for an SEC investigation or shareholder suit; an E&O carrier has denied coverage on a professional malpractice claim; a directors and officers loss is approaching the retention limit and a Side A drop-down policy may be in play; or a cyber carrier has denied coverage on a ransomware loss citing a war exclusion or prior-knowledge exclusion. Construction-defect coverage disputes (additional insured tenders, completed-operations issues, your-work exclusions) are a steady volume of Chicago coverage litigation.
Illinois coverage law has a few features worth knowing. Section 155 of the Illinois Insurance Code allows policyholders to recover attorney's fees and additional damages when an insurer's conduct is vexatious and unreasonable. The Illinois Supreme Court applies an objective reasonableness standard. Illinois recognizes the common-law duty to settle and broad bad-faith exposure when an insurer refuses a reasonable within-policy-limits settlement and a judgment exceeds the limit. Illinois generally follows the "eight corners" rule for the duty to defend — the carrier must defend when allegations in the underlying complaint potentially fall within coverage, with limited exceptions. Choice-of-law and policy-interpretation rules are well-developed in the First District Appellate Court and the Northern District of Illinois.
Get a coverage opinion before signing on to a settlement that may compromise coverage, before tendering late notice, and before responding to a carrier's request for an examination under oath. The early decisions drive the outcome more than the trial work does.

Chicago and Bloomington/Normal offices. Represents carriers in coverage disputes and declaratory judgment actions across Illinois state and federal courts. Strong on property, construction defect, automobile, and commercial general liability coverage matters. Mid-market alternative to top-tier defense firms.
Pre-litigation coverage opinion / demand letter. $3,500-$15,000. Frequently resolves the matter without filing. A well-drafted demand under Section 155 changes a carrier's calculus.
Declaratory judgment action (single-policy coverage dispute). $50,000-$180,000 through summary judgment. Most Chicago coverage actions resolve at summary judgment.
Complex first-party / business interruption litigation. $150,000-$500,000+. Document-heavy with extensive damages discovery and accounting expert work.
Bad-faith case (Section 155). Section 155 allows attorney's fees and statutory damages capped at the lesser of $60,000 or 60% of the unpaid claim above policy limits — but the fees can shift the economics substantially in mid-sized cases. Policyholder firms often work on a hybrid or reduced-hourly model when Section 155 is in play.
D&O / E&O coverage disputes. $150,000-$600,000+. Complex policy interpretation, often involving multiple carriers and excess towers.
Hourly rates. Chicago carrier-side defense rates: $325-$725. Policyholder-side recovery practices: $525-$1,100. Some policyholder firms take cases on contingency or hybrid when the disputed amount exceeds $1M.
Pre-suit coverage opinion and demand: 2-6 weeks from engagement.
Filing through summary judgment: 9-18 months in Cook County Circuit Court and the Northern District of Illinois for clean coverage cases. Discovery is typically narrower than tort discovery — focused on the underlying loss, the policy, and the carrier's claim file.
Trial: 18-30 months from filing for cases that don't resolve at summary judgment. Most coverage cases settle within 6 months of summary judgment briefing once both sides see how the policy reads against the loss facts.
Bad-faith remedies: Section 155 attorney's fees usually awarded at the end of the underlying coverage trial in the same proceeding.
Appeals: First District Appellate Court typically 9-18 months from notice of appeal to decision.
