Filing a Chicago mechanics lien is one of the most powerful tools available to contractors, subcontractors, and material suppliers who have not been paid for construction work. A Chicago mechanics lien attaches directly to the property where work was performed, giving the lienholder a secured claim that can force payment — even through a foreclosure sale if necessary.
Howard East’s litigation attorneys handle Chicago mechanics lien filings, enforcement, and defense for construction industry clients throughout the metropolitan area.
Understanding the Chicago Mechanics Lien Process
Illinois law grants contractors and suppliers who improve real property the right to file a mechanics lien against that property if they are not paid. The Illinois Mechanics Lien Act (770 ILCS 60) establishes specific requirements for creating, perfecting, and enforcing these liens. For work performed in Chicago, the lien must be recorded with the Cook County Recorder of Deeds.
The process begins before construction starts. General contractors must ensure their contracts are properly documented, while subcontractors and suppliers must serve a notice of their right to file a lien — commonly called a “preliminary notice” or “subcontractor notice” — to preserve their lien rights. Missing this step can forfeit the right to file a Chicago mechanics lien entirely.
Strict Deadlines for Filing a Chicago Mechanics Lien
Illinois imposes tight deadlines that must be followed precisely. Subcontractors must serve notice on the property owner within 90 days of last performing work or supplying materials. The mechanics lien claim itself must be recorded within four months after the claimant’s last date of work. A foreclosure suit must be filed within two years after the last date of work or the lien expires automatically.
These deadlines are strictly enforced by Illinois courts. Even one day late and the lien rights are lost. Our business lawyers track all critical dates and ensure every filing is completed on time to protect our clients’ Chicago mechanics lien rights.
What Must Be Included in the Lien Claim
A valid Chicago mechanics lien claim must contain specific information required by statute. This includes the claimant’s name and address, the property owner’s name, a legal description of the property, the amount claimed, and a description of the work performed or materials supplied. The claim must be verified by affidavit and recorded in the county where the property is located.
Errors in the lien claim — such as an incorrect legal description, wrong owner name, or inflated claim amount — can render the lien invalid or provide grounds for the property owner to challenge it. Having experienced counsel prepare and review the filing helps avoid these costly mistakes.
Enforcing and Defending Against a Chicago Mechanics Lien
Once filed, a Chicago mechanics lien clouds the property title and can prevent the owner from selling or refinancing until the lien is resolved. Property owners who believe a lien is invalid can petition the court to discharge it by posting a bond or challenging the lien’s validity. Lien claimants must be prepared to defend the validity of their claim and, if necessary, pursue foreclosure to collect payment.
The Cook County Recorder’s office processes these filings, and our dispute resolution attorneys handle both enforcement actions for unpaid contractors and defense strategies for property owners facing improper lien claims.

Frequently Asked Questions About Chicago Mechanics Liens
What is a Chicago mechanics lien?
A Chicago mechanics lien is a statutory claim against real property filed by a contractor, subcontractor, or material supplier who has not been paid for construction work performed on that property. It creates a security interest in the property that can be enforced through foreclosure under the Illinois Mechanics Lien Act.
How long do I have to file a mechanics lien in Chicago?
Subcontractors must serve notice within 90 days of their last work date, and the lien claim must be recorded within four months after the last date of work. A foreclosure action must be filed within two years. These deadlines are strictly enforced and missing them forfeits your lien rights.
Can a property owner remove a mechanics lien?
Yes. A property owner can petition the court to discharge a Chicago mechanics lien by posting a substitute bond, paying the claimed amount into court, or proving the lien is invalid due to procedural defects, expired deadlines, or inflated claims. Legal counsel can evaluate the best strategy based on the specific circumstances.
