How Change Orders Become Major Construction Litigation Issues

 Posted on May 22, 2026 in Business & Contract Disputes

Change orders are a normal part of almost every construction project. Scope changes, unexpected site conditions, and design revisions happen all the time. The problem is not that changes occur. The problem is what happens when those changes are not handled properly.

A change order that seems minor in the moment can turn into a major legal dispute over unpaid work, broken timelines, and significant financial losses for your business. If you are a construction company owner dealing with a change order dispute in 2026, our McHenry County commercial litigation lawyers can help you understand your options and protect what you have worked hard to build.

In Illinois construction disputes, a change order generally refers to a modification to the original contract that adjusts the scope of work, the cost, or the timeline. When these modifications are handled correctly, they keep your projects moving and your cash flow protected. When they are undocumented, disputed, or ignored, they become the foundation of some of the most expensive and time-consuming construction litigation cases in Illinois courts.

What Makes a Construction Change Order Valid in Illinois?

Illinois courts have laid out clear requirements for proving a valid change order claim. According to established Illinois construction law, as a contractor seeking payment for extra work, you must show all of the following:

• The extra work was outside the scope of the original contract.
• The owner or upstream party actually requested the extra work.
• The owner or upstream party agreed to pay for it, either in words or by their conduct.
• You did not voluntarily choose to do the extra work on your own.
• The extra work was not needed because of a mistake on your part.

Most construction contracts also require change orders to be in writing and signed by the owner before the work begins. That requirement sounds simple, but in practice, it gets skipped all the time on busy job sites, and that is where your exposure begins.

Why Do Verbal Change Orders Put Your Construction Business at Risk?

On a busy job site, things move fast. A project manager tells your crew to make a change. You agree over the phone to additional work. Someone gives the go-ahead by text without a signed document. These situations happen constantly, and they create serious legal and financial risk for your business.

Illinois courts have recognized that verbal change orders can sometimes be enforced. This is especially true when the parties had a pattern of handling changes that way throughout the project or when you proceeded with extra work based on a clear direction from the owner or architect. But relying on that is a gamble. Courts examine each situation individually. The outcome depends heavily on what evidence exists to support what was said and agreed to.

The safest position for your business is always to have changes in writing before work begins. When that does not happen, preserving every email, text, and note about the change becomes critical to your ability to get paid.

What Is Scope Creep and Why Does It Threaten Your Bottom Line?

Scope creep is what happens when a project gradually expands beyond what was originally agreed to, piece by piece, without formal change orders being issued. Each addition may seem small. However, over the course of a long project, they add up to significant extra work and cost that was never formally approved or priced.

By the time you try to collect for all of that extra work, the owner may push back and claim it was all part of the original scope. Without written change orders documenting each addition, you have a very hard time proving what was extra and what was included in the base contract. That can mean doing weeks of additional work without getting paid for any of it.

How Do Change Orders Affect Your Project Timeline and Liability?

Changes to scope almost always affect the schedule. But that connection is easy to overlook when you are focused on getting the work done. When you agree to extra work without also getting a written extension to the project timeline, you can end up in a situation where you are blamed for delays that were actually caused by the change itself.

Delay claims are among the most expensive and hard-fought areas of construction litigation. If a change order added two weeks of work but no schedule extension was documented, you could face liquidated damages or breach of contract claims for finishing late, even though the delay was not your fault. Protecting your timeline is just as important as protecting your payment.

What Should Be Included in a Change Order?

A well-written change order should always address three things. What work is being added or changed? How much did it cost? How much time did it add to the project? Leaving any one of those out creates a gap that can be used against you later.

What Are the Most Common Reasons Change Order Disputes End Up in Court?

Change order litigation in Illinois typically stems from a handful of recurring problems that construction company owners face regularly:

• The owner claims a change was inside the original scope, while you know it was not.
• You performed work based on a verbal direction, and the owner later refused to pay for it.
• A change was agreed to, but the price was never settled before your crew started the work.
• You did not follow the contract's required process for submitting and getting approval for change orders, which can affect your ability to recover payment even when the work was clearly extra.
• The change caused delays that neither party accounted for in writing at the time.

Under the Illinois Uniform Arbitration Act, 710 ILCS 5, many construction contracts require disputes to go through arbitration before or instead of court. If your contract has a mandatory arbitration clause, filing a lawsuit without going through that process first can result in your case being dismissed. Knowing what your contract requires before a dispute escalates can save your business significant time and money.
