Find the Right Payment Remedy

Unpaid Contractors in Illinois

Illinois law provides multiple paths to recover construction payments — but the right remedy depends on whether your project is public or private, your position in the contracting chain, and how much time has passed. Start here to identify your options.

Deadlines Are Running

Every payment remedy in Illinois has strict time limits. Subcontractors must send a Section 24 notice within 90 days. Lien claims must be recorded within 4 months. If you suspect nonpayment, act now — once a deadline passes, the remedy is gone permanently.

Which Remedy Is Right for You?

The right approach depends on your role, the project type, and how much time has passed. An experienced construction attorney can evaluate your situation and recommend the best path forward.

Payment Remedies Explained

Mechanics Lien Filing

Private Projects

Record a claim for lien against the property where you furnished labor or materials. A mechanics lien encumbers the title and can force a sale to satisfy the debt. Available only on privately owned property.

Mechanics Lien Enforcement

Private Projects

Once a lien is recorded, enforcement means filing a foreclosure action in court. This compels resolution — property owners cannot sell, refinance, or ignore a properly recorded lien without addressing it.

Payment Bond Claim

Public Projects

On bonded public projects, the surety company guarantees the general contractor's payment obligations. A payment bond claim targets the surety — not the public entity — and follows notice and suit procedures under 30 ILCS 550.

Lien on Public Funds

Public Projects

When public funds have not yet been fully disbursed to the general contractor, you may serve a notice to trap those funds under 770 ILCS 60/23. This is often used alongside or instead of a payment bond claim.

Demand Letter and Collections

All Projects

A formal demand letter from an attorney is often the first step in any payment recovery effort. It creates a written record of your claim, demonstrates seriousness, and frequently produces payment without the need for a lien or bond filing.
