Top Contract Disputes in Illinois and How to Avoid Them

 Posted on October 14, 2025 in Business & Contract Disputes

Virtually every business transaction has a contract behind it. Even the most carefully written contract can end up in a dispute. These disputes can quickly drain financial resources, damage business and personal reputations, and ultimately end up in court – an expensive, time-consuming process. With the right legal planning, you can reduce your risk of contract disputes while protecting your business.   

Ambiguous language or terms are a major cause of contract disputes, causing both sides to interpret the contract differently. Other causes of contract disputes include unforeseen changes in circumstances and economic fluctuations. Contracts drafted by a layperson or those rushed can have overlooked details, which can lead to contract disputes.   

Naturally, you want to be certain that your business contracts are as solid as they can be, leaving you with the least amount of legal exposure. Consulting with an experienced Rock Island County, IL business law attorney from SpyratosDavis LLC who understands your company’s needs and goals is your best course of action to avoid contract problems.

What Are the Five Most Common Types of Contract Disputes?

Contract disputes are common and vary widely, depending on the type of business. The five most common types of contract disputes include:

Breach of Contract Disputes

Breach of contract disputes arise when one party fails to fulfill their obligations under a legally binding agreement. Disputes may be resolved through negotiation, arbitration, or mediation; if these remedies fail, then a lawsuit will be filed in court.  Breach of contract disputes can include:

• Failure to complete the agreed-upon duties.
• Failure to perform those duties within the agreed-upon timeframe.
• Substandard performance
• Non-payment or failure to meet payment milestones.

Anticipatory breaches occur when one party notifies the other that they will not be able to fulfill their obligations before the performance is due. Under 810 ILCS 5/2-725, any action for breach of contract for a sales contract must be commenced within four years after the cause of action has accrued.

Employment Agreements

Employment agreements often have non-compete and non-solicitation clauses. When these clauses are breached, a dispute can occur. Wage disputes also involve wrongful termination and unpaid compensation. There are also disagreements over intellectual property ownership, the terms of termination and severance pay, and the interpretation of clauses concerning confidentiality and benefits.

Commercial Lease Agreements

Disputes over commercial lease agreements often involve disagreements between tenants and landlords regarding rent, repairs, or the use of the premises. Other common commercial lease agreement disputes center around lease renewals, tenant insolvency, ambiguous lease language, or break clauses.

Partnership or Shareholder Agreements

Partnership or shareholder agreements may not be clearly written, which can lead to disputes. Other reasons for partnership or shareholder agreements include conflicts over roles and responsibilities, differing visions for the future of the business, disagreements over finances, or one partner may have breached his or her fiduciary duty.

Construction Contracts

Common disputes related to construction contracts can arise from payment disagreements, changes to the scope of work, ambiguous contract terms, design and construction errors, mechanics’ liens, unforeseen site conditions, project delays, and substandard or defective work. These disputes can often be avoided through clear communication and adequate documentation.

Why Are Contract Disputes Common and What Are the Consequences?

Virtually every business relies on contracts in employment, real estate, and services, and the state of Illinois has a strict legal framework for contract enforcement. As economic circumstances continue to decline, financial pressures can lead to more disputes. The legal consequences of a contract dispute could be damages (compensatory, consequential, or liquidated), injunctions in non-compete and IP-related cases, reputational harm, and business-related breakdowns.
