How we match your Illinois business dispute case

When you submit a Illinois business dispute matter, we route it through a national network of independent partner firms and put it in front of the one that fits best — based on the kind of case it is, what it is likely to involve, where it has to be handled, and who has capacity to take it on now.

Case type

A business dispute matter needs someone who handles business dispute work day to day, not a generalist. Practice area is the first filter.

Size and complexity

Some firms are built for catastrophic injury and multi-party litigation; others resolve straightforward claims quickly. We weigh what your matter is likely to involve against how each firm actually works.

Jurisdiction and licensing

Your matter is decided under Illinois law, so it goes to an attorney licensed in Illinois who regularly appears where your case would be heard.

Capacity and fit

Availability, conflicts of interest and language all matter. If the best-fit firm cannot take your case, we route it to the next one that can — or tell you plainly when no one in the network is the right answer.

Every partner reviews your case for free. Injury and workers’ compensation matters are handled on contingency — no fee unless you win. Other matters are quoted upfront, before you commit to anything.

DearLegal provides marketing and matching services and is not a law firm. Submitting a case does not create an attorney-client relationship. Matches depend on case type, jurisdiction and firm availability.

Illinois has adopted the UCC in full (810 ILCS 5) and operates the Commercial Calendar Section of the Cook County Circuit Court (Law Division) — a dedicated docket for commercial cases over $30,000 (and qualifying complex cases) with active judicial management. Outside Cook County, commercial cases run through the general civil dockets of the Illinois Circuit Court. Illinois has one of the longer contract limitations periods in the country (10 years on written contracts), the Illinois Consumer Fraud and Deceptive Business Practices Act (815 ILCS 505), and the Illinois Trade Secrets Act (765 ILCS 1065). Illinois non-competes are governed by the Illinois Freedom to Work Act (820 ILCS 90), as amended in 2022.

Meanwhile, don’t

Letting strong evidence go stale even though Illinois’s 10-year written-contract SOL (735 ILCS 5/13-206) gives you time — witnesses and documents fade long before 10 years
Failing to preserve emails, Slack, texts, and contract files immediately
Talking directly to opposing counsel without your own attorney and giving away admissions
Accepting partial payment with language that operates as accord and satisfaction under 810 ILCS 5/3-311 and waiving the rest of the claim
Failing to timely file a UCC-1 financing statement or perfect a mechanic’s lien under 770 ILCS 60
Drafting non-competes that violate the 2022 Freedom to Work Act salary thresholds and notice requirements

Illinois business litigation is typically billed hourly against a retainer. Plaintiff-side commercial collections, certain fraud and trade-secret cases, and contract cases with strong fee-shifting can be handled on 33%–40% contingency or a hybrid fee. A good Illinois business litigator will walk you through fee structures and budgets upfront.

Exhibit E

What your Illinois business dispute compensation can include

A Illinois business dispute recovery is built from several parts. Tap one to see what it covers.

Compensatory / Actual Damages

Direct losses caused by the breach — the benefit of the bargain. Goal: put the non-breaching party where they would have been.

Settle when the relationship matters and litigation costs would eat your recovery. Litigate when the other side won’t engage, you need an injunction, your case qualifies for the Commercial Calendar (over $30,000 in Cook County), or you have a fee-shifting clause. Cook County’s Commercial Calendar moves faster than the general civil docket and assigns judges with commercial expertise.

Move quickly. Illinois’s LLC Act (805 ILCS 180) and Business Corporation Act (805 ILCS 5) give you books-and-records rights, fiduciary-duty claims, and dissolution remedies. Demand records in writing, preserve everything, and get counsel before you’re locked out.

Four elements: a valid contract, your performance or excuse, the other side’s breach, and damages. Documents win. Illinois recognizes the implied covenant of good faith and fair dealing.

Usually yes. The Federal Arbitration Act preempts most state-law challenges and Illinois courts routinely enforce commercial arbitration clauses. Illinois has also adopted the Uniform Arbitration Act (710 ILCS 5).

Illinois has adopted the Uniform Fraudulent Transfer Act (740 ILCS 160). When a debtor moves assets to dodge creditors, UFTA lets you claw assets back or get a judgment against the transferee.

The Illinois Freedom to Work Act (820 ILCS 90), amended effective January 2022, requires reasonable scope, prohibits non-competes for employees earning under $75,000 and non-solicits for those under $45,000 (thresholds increase over time), and imposes notice and consideration requirements. Overbroad clauses risk being struck rather than blue-penciled.

Illinois follows the American Rule with exceptions. Contractual prevailing-party clauses are routinely enforced. The Trade Secrets Act, Consumer Fraud Act, and other statutes also fee-shift. Illinois Supreme Court Rule 137 awards fees for unsupported pleadings.

Other case types in Illinois

All Illinois practice areas →

Animal Incident attorneysIllinois holds dog owners strictly liable — the owner pays for unprovoked attacks even without prior knowledge of viciousness.

Car Accident attorneysIllinois is a fault state with 51% modified comparative — and mandatory uninsured-motorist coverage gives most plaintiffs a backup recovery layer.

Consumer Protection attorneysThe Illinois Consumer Fraud Act lets consumers recover actual damages plus attorney fees — and the state’s biometric-privacy law drives unique fingerprint and face-scan claims.

Criminal Defense attorneysIllinois eliminated cash bail in 2023 — pretrial release practice is now substantially different from most other states.

Defective Product attorneysIllinois holds manufacturers strictly liable for defective products, and the Illinois Supreme Court continues to shape how far that liability reaches.

Employment attorneysThe Illinois Human Rights Act covers more protected classes than federal law — and recent biometric-privacy decisions have reshaped employer time-clock liability.

Family Law attorneysIllinois divides marital property equitably — and state law presumptively splits property acquired during marriage between spouses.

Immigration attorneysIllinois is a Trust Act state — local law enforcement is restricted from cooperating with ICE detainers, which shapes detention and removal practice in Cook County.

Lemon Law attorneysIllinois’s Lemon Law covers manufacturer defects within 12 months/12,000 miles — narrower than many states, so timing is critical.

Medical Malpractice attorneysIllinois med-mal damages caps were struck down in 2010 — but the affidavit-of-merit requirement still gates every case.

Personal Injury attorneysA 2-year filing deadline and 51% modified comparative fault frame every Illinois PI case — Cook County culture often shapes settlement value.

Slip and Fall attorneysIllinois follows the natural-accumulation rule on snow and ice — landowners generally aren’t liable for natural ice unless they made the condition worse by their own actions.

Social Security Disability attorneysIllinois SSA hearing offices in Chicago, Oak Park, and Orland Park have moderate-to-long waits — counsel helps build the medical record SSA needs.

Workers’ Compensation attorneysThe Illinois Workers’ Compensation Commission runs claims — and Illinois remains one of the more employee-friendly comp systems in the Midwest.
