Common Mistakes to Avoid When Filing a Mechanics Lien in Illinois

March 10, 2025

Filing a mechanics lien in Illinois can be a powerful remedy for general contractors, subcontractors, and suppliers seeking payment for their work. The Illinois Mechanics Lien Act (770 ILCS 60/) grants specific rights to these parties, allowing them to record a lien against property when compensation is delayed or withheld. However, even a minor oversight can invalidate a claim or reduce its enforceability. 

Seeking guidance from an Illinois mechanics lien lawyer at Grzymala Law Offices in Illinois is a prudent way to help secure proper compliance. Below are common mistakes to avoid when filing a mechanics lien in Illinois. 

Mistake 1. Missing Critical Deadlines

One of the most frequently cited issues in mechanics liens is missing the required deadlines. Under the Illinois Mechanics Lien Act, general contractors typically must record their lien within four months after finishing their work. Subcontractors have a shorter window for required notices and filings. If these time limits pass, the lien rights may be forfeited. For instance, in Kiefer v. Reis, 331 Ill. App. 3d 57 (2002), the court highlighted that a late filing can render the lien unenforceable.

Mistake 2. Failing to Provide Proper Notice

Failure to provide timely notice is another common pitfall. The Act requires specific notices to be delivered to the property owner, especially when dealing with residential projects governed by the Illinois Home Repair and Remodeling Act (815 ILCS 513/). Subcontractors, in particular, must ensure owners are duly informed of services provided. The lack of proper notice can lead to a disallowed lien. Whether you are a supplier or a contractor, verifying the notice requirements is vital, as certain projects have additional rules that must be followed.

Mistake 3. Inaccurate or Incomplete Lien Statements

Accuracy in the lien document is paramount. If the lien statement omits essential details—such as the correct property identification, exact amount owed, or the legal name of the party who hired you—the lien’s validity can be jeopardized. A skilled Chicago mechanics lien lawyer can ensure statements are correct to avoid errors that could invalidate the claim. Even small typographical mistakes might complicate enforcement in court, putting your right to payment at risk.

Mistake 4. Confusing Residential and Commercial Requirements

Residential properties frequently have additional layers of protection for homeowners. For instance, contractors working on residential properties must adhere to the Illinois Home Repair and Remodeling Act, which sets guidelines on written contracts, consumer rights, and proper notices. A Chicago mechanics lien attorney can clarify differences between commercial and residential lien filings. Overlooking these requirements can expose contractors to claims of noncompliance and potential statutory penalties.

Mistake 5. Overlooking Preliminary Legal Protections

Signing a contract that waives lien rights prematurely can undermine your leverage if disputes about payment arise. Always review contract clauses that may limit lien rights. Check for unconditional or partial lien waivers hidden in contract language. If these waivers are signed without a clear understanding, you may lose the ability to file a lien.

Mistake 6. Neglecting Documentation and Recordkeeping

Meticulous record keeping is essential to support your lien claim. This includes maintaining invoices, contracts, delivery tickets, change orders, and correspondence evidencing the work performed or materials supplied. Under the Illinois Mechanics Lien Act, well-organized documentation helps substantiate the total amount owed and the timeline of your work. If an owner disputes your claim, a detailed paper trail can strengthen your position.

Mistake 7. Waiting Too Long to Enforce Your Lien

Even if you record your lien on time, it must be enforced within the statutory period. In many cases, the lienholder has two years from the completion of work to file suit to foreclose on the lien. Waiting too long to initiate legal action can lead to the lien’s expiration. Checking the date of substantial completion and staying vigilant about deadlines is key.

Mistake 8. Assuming a Lien Will Automatically Guarantee Payment

Mechanics liens are potent tools, but they do not guarantee immediate payment. Additional legal actions may be needed to enforce the lien and force a sale of the property or prompt a negotiated settlement. Consulting an Illinois mechanics lien lawyer who understands collection strategies can help secure the compensation you earned.

Mistake 9. Not Seeking Professional Counsel

Illinois construction law can be unforgiving. From ensuring proper notice to perfecting the lien, every step must conform to statutory rules.
