Finding the right contract lawyer in Chicago can help you protect your legal rights, review business agreements, negotiate contract terms, and resolve disputes. This list covers two different jobs. One is writing contracts that hold up, and the other is suing or defending when a deal falls apart. The firms below handle both, though each has a distinct strength.
Chicago’s legal market also changed shape recently. Two of the city’s oldest firm names disappeared through mergers, which matters if you’re searching for a lawyer you hired years ago.
Illinois Contract Law: Quick Facts
- Written contracts: Illinois generally allows 10 years to sue for breach.

1. Jenner & Block LLP
For a high-stakes contract dispute in Illinois, Jenner & Block sits at the top of the rankings. Chambers USA 2026 placed the firm in Band 1 for general commercial litigation in Illinois. It also holds Band 1 rankings for policyholder insurance disputes and white-collar defense.
Partner Terri Mascherin holds an individual Band 1 ranking for general commercial litigation. Overall, Jenner’s Chicago lawyers earned 35 individual Chambers rankings across 24 practice areas in June 2026.
Insurance coverage fights are contract disputes too. When an insurer refuses to pay under a policy, Jenner’s Band 1 policyholder team is among the strongest options in the state.
Call them about: major commercial breach claims and insurance policy disputes.
2. Bartlit Beck LLP
Bartlit Beck does something unusual for a top trial firm: it avoids the billable hour. The firm describes its model as fixed and success-based fees, designed to reward results instead of time spent.
Benchmark Litigation lists Bartlit Beck in its highest Illinois tier and has named it a Top 20 Trial Firm every year since 2015. More than three-quarters of its lawyers are partners, and the average attorney has over 18 years of experience. Offices in Chicago and Denver handle cases nationwide.
Call them about: contract disputes headed for trial, especially when hourly fees would be prohibitive.
3. Winston Taylor (Formerly Winston & Strawn)
Founded in Chicago in 1853, Winston & Strawn was one of the city’s oldest law firms. On June 1, 2026, it combined with Taylor Wessing’s UK business to become Winston Taylor, a transatlantic firm of about 1,400 lawyers. Some earlier reports targeted May 2026 for the combination, but the firm’s own site gives June 1.
The firm’s headquarters remains in Chicago at 300 North LaSalle, overlooking the Riverwalk. For companies signing cross-border supply, licensing, or distribution agreements, the firm’s expanded reach in the UK and Europe is the main draw.
Call them about: international commercial contracts and complex corporate agreements.
4. Much Shelist, P.C.
Not every business needs a global firm. Founded in 1970 and headquartered on North Wacker Drive, Much Shelist has more than 100 attorneys focused on business counseling, transactions, and litigation.
Chambers ranks the firm in Illinois for general commercial litigation, corporate deals, and construction, with five ranked construction lawyers. That construction depth matters, because builder and subcontractor agreements generate some of the most frequent contract disputes in Chicago.
Partner Steven P. Blonder wrote the Illinois litigation trends chapter for Chambers’ 2026 Litigation Practice Guide.
Call them about: construction contracts, mid-market business agreements, and commercial litigation.
5. Smith Gambrell Russell (SGR)
If you once hired Freeborn & Peters, your lawyer may now work here. Freeborn combined with Atlanta-based SGR on March 1, 2023, adding more than 100 Chicago lawyers. SGR had entered Chicago a year earlier by combining with the litigation boutique Figliulo & Silverman.
The combined firm has about 400 attorneys across 14 offices, giving mid-sized companies national coverage.
Call them about: commercial litigation and day-to-day business contracts for growing companies.
Contract Clauses That Cause the Most Fights
Many disputes trace back to a few overlooked provisions:
- Termination rights: Who can exit, with how much notice, and what happens to pending payments.
- Indemnification: Who pays when a third party sues.
- Limitation of liability: Caps on damages that can wipe out a strong claim.
- Venue and arbitration: Whether a dispute stays in Cook County or moves to arbitration elsewhere.
- Restrictive covenants: Noncompete and non-solicit terms that may violate Illinois law.
FAQs
Q1. How long do I have to sue for breach of contract in Illinois?
A: Usually 10 years for written contracts and five years for oral ones. Sales of goods under the UCC generally carry a shorter four-year deadline.
Q2. Is my noncompete agreement enforceable in Illinois?
A: Not if you earn $75,000 or less a year. Above that, courts check whether the restriction is reasonable and supported by adequate consideration, such as two years of employment.
Q3. How much does a contract lawyer cost in Chicago?
A: Simple contract reviews are often billed as flat fees, while disputes are usually hourly. Some trial firms, like Bartlit Beck, use fixed or success-based fees instead.
Q4. Should I sign a contract with an arbitration clause?
A: Possibly, but understand the trade-off. Arbitration is private and often faster, but appeal rights are very limited. Have a lawyer review the clause before signing.
