As a contractor or subcontractor, you've completed quality work, but payment hasn't arrived as promised. A mechanics lien can be a powerful tool to secure what you're owed, but Illinois law is unforgiving when it comes to procedural mistakes. One small error can completely destroy your claim, leaving you with no recourse.

Here's what you need to know to protect your lien rights.

The Golden Rule: Strict Compliance is Everything

Illinois courts require strict compliance with mechanics lien procedures. This isn't an area where "close enough" works—you must follow every requirement precisely, or risk losing your lien entirely. The burden is on you to prove you've satisfied every statutory requirement.

Critical Deadlines You Cannot Miss

Note: This is not a comprehensive list of all deadlines. Consult with an attorney for deadlines specific to your situation.

For Subcontractors

• 60-Day Notice: For residential projects, notify the homeowner within 60 days of starting work.
• 90-Day Notice: Notify the owner and any lender within 90 days of completing your work—this is crucial for protecting your rights against third parties.
• 2 Years: File your lawsuit within two years of completing your contract.

For General Contractors

• 4 Months: Record your lien claim within four months of completion to bind third parties like lenders and new buyers.
• 2 Years: File your lawsuit within two years of completing your contract.

Documentation That Can Make or Break Your Case

Your lien claim must be verified by affidavit and include:

• A brief statement of your contract
• The balance due after allowing all credits
• A sufficiently correct description of the property
• Proper notarization or sworn verification

The Completion Date Trap

Determining when your work was "complete" is trickier than it sounds. Courts may not extend deadlines for:

• Minor punch-list items
• Warranty repairs
• Trivial touch-up work

Don't try to revive a missed deadline by performing unnecessary work—courts see through this tactic.

How Much Can You Claim?

Be precise with your lien amount. Include:

• Contract balance due
• Approved change orders
• Materials delivered to the site

Don't include:

• Attorney's fees
• Interest (unless contractually agreed or provided by statute)
• Speculative future costs

Warning: Overstating your claim can result in the entire lien being declared fraudulent and void, even if some amount was legitimately owed.

Property Description Requirements

Get the legal description from a title company or on the advice of a lawyer—don't guess or use the common address. An incorrect legal description can invalidate your entire claim.

Protect Yourself From Payment Without a Lien Waiver

Never provide unconditional lien waivers until payment has cleared. Consider using conditional lien waivers that become effective only upon payment.

The 30-Day Demand: Know Your Rights

If an owner serves you with a 30-day demand, you must file a lawsuit within 30 days or lose your lien entirely. This deadline is strictly enforced—there are no extensions or excuses.

When to Seek Legal Help

Consider consulting an attorney if:

• You're unsure about any deadline
• The project involves multiple properties
• There are disputes about completion dates
• The owner has filed bankruptcy
• You're facing a 30-day demand

The Bottom Line

A mechanics lien is a powerful remedy, but only if properly executed. The time and cost of getting professional guidance upfront is minimal compared to losing your entire claim due to a procedural error.
