Illinois has some of the most developed case law on LOI enforceability in the country. In the landmark case Quake Construction, Inc. v. American Airlines, Inc., the Illinois Supreme Court held that a letter of intent can be an enforceable contract if the parties intended to be bound by its terms — even if a formal agreement was contemplated. Illinois courts apply a four-factor test examining the language of the LOI, the existence of open terms, whether partial performance occurred, and the customary practice in the industry.
Whether you're structuring an M&A deal on LaSalle Street, negotiating a commercial real estate transaction in Chicago's Loop, or outlining terms for a manufacturing acquisition in the suburbs, a precisely drafted LOI is critical. Chicago is the nation's third-largest M&A market, and Illinois's diverse economy — spanning financial services, manufacturing, healthcare, and technology — generates constant demand for clear preliminary agreements.
SignAI generates your Illinois LOI with state-specific provisions informed by Quake Construction and related precedent — clearly separating binding from non-binding terms, addressing Illinois's four-factor enforceability analysis, and including clauses for due diligence, confidentiality under the Illinois Trade Secrets Act (765 ILCS 1065), exclusivity, and break-up fees.

FAQ
It can be. Under Quake Construction, Inc. v. American Airlines, Inc., the Illinois Supreme Court held that an LOI may be enforceable if the parties intended to be bound. Illinois courts apply a four-factor test: the explicit language of the LOI, whether open terms exist, whether partial performance occurred, and whether it's customary in the industry to have a formal contract. SignAI structures your LOI to clearly control enforceability.
In Quake Construction v. American Airlines (1990), the Illinois Supreme Court established that letters of intent can be binding contracts depending on the parties' intent. The court examines four factors: the LOI's language, open terms, partial performance, and industry custom. This means Illinois LOIs must be carefully drafted to clearly state what is and isn't binding.
No. Illinois does not require attorney involvement for a valid LOI. SignAI generates a professionally structured, Illinois-specific LOI informed by Quake Construction and related case law. For M&A deals in the eight-figure range or transactions involving publicly traded companies, consulting an Illinois corporate attorney is advisable.
Yes. Break-up fees are enforceable in Illinois when they meet the standard for valid liquidated damages — they must be a reasonable estimate of anticipated damages and not a penalty. Illinois courts will evaluate whether the fee is proportionate to the deal's value and the non-breaching party's potential losses.
Illinois recognizes the implied covenant of good faith and fair dealing in existing contracts. If your LOI includes a binding obligation to negotiate in good faith toward a definitive agreement, Illinois courts can enforce it. A party that fails to negotiate genuinely — for example, by making unreasonable last-minute demands — may face liability.
