When a construction project goes sideways — when a developer runs out of money, a general contractor folds, or a bankruptcy filing hits — there is one question that determines whether you walk away with a check or walk away with nothing:
Are you a secured creditor or an unsecured creditor?
That single distinction decides where you sit in the payment line, how much you recover, and in many cases, whether you recover anything at all. Illinois law gives contractors and suppliers the tools to become secured — but only if those tools are used correctly and on time.
The Champagne Tower
Picture a champagne tower — glasses stacked in a pyramid, the bottle pouring into the top glass first. When that top glass overflows, the champagne spills down to the next level. Then the next. The glasses at the top are always full. The glasses at the bottom only get what is left over — if anything.
When a construction project goes bust, that champagne tower is the creditor priority stack.
The secured creditors are at the top. Their glasses fill first. They have a legal claim attached to a specific asset — the real property itself — and that claim must be satisfied before anything flows downward.
The unsecured creditors sit at the bottom. They are owed money, but their claim floats in the air — attached to nothing tangible. They wait for whatever trickles down after every secured creditor, every priority tax claim, and every administrative expense is paid in full. In most construction bankruptcies, by the time the pour reaches the bottom glasses, the bottle is empty.
A mechanic lien is what puts you at the top of that tower.
Secured vs. Unsecured — What It Actually Means
Unsecured Creditor — Bottom of the Tower
An unsecured creditor has a valid claim but no legal interest attached to any specific asset. In bankruptcy proceedings, unsecured creditors are paid last — after the bankruptcy trustee's fees, priority tax claims, and every secured creditor with a perfected interest in a specific asset.
In construction bankruptcies, unsecured creditors routinely receive pennies on the dollar. Many receive nothing. Having a signed contract, a stack of unpaid invoices, or even a judgment means very little if you are standing at the bottom of the tower when the bottle runs out.
Secured Creditor — Top of the Tower
A secured creditor holds a legal interest attached to a specific asset. In construction, that asset is the real property itself. A properly perfected mechanic lien encumbers the title to the land and the improvement — the owner cannot sell, refinance, or transfer the property without satisfying your claim.
In a bankruptcy, your perfected lien is a secured claim against the property. You are not competing with every other unsecured creditor for a share of whatever is left. You have a priority interest in a specific, identifiable asset. Your glass fills first.
What Happens in Bankruptcy If You Are Unsecured
When a GC or developer files for bankruptcy, an automatic stay halts most collection actions. The bankruptcy trustee then liquidates available assets in priority order:
Trustee fees and administrative costs
Priority tax claims
Secured creditors — those with perfected liens on specific property
General unsecured creditors — everyone else
A properly recorded mechanic lien filed before the bankruptcy petition moves you out of that unsecured pool entirely. You are no longer waiting for a trickle. You have a perfected security interest in real property that must be addressed before that property can be sold, transferred, or cleared.
How a Mechanic Lien Secures Your Position
On private projects in Illinois, the mechanic lien under 770 ILCS 60 is your tool for becoming a secured creditor. It attaches directly to the real property — not to the GC, not to the developer's bank account, but to the land and the building itself — enforceable even if every party above you in the construction chain has gone insolvent.
The earlier you act, the more protected you are. Once the owner receives your Section 24 notice, they are legally required under 770 ILCS 60/27 to withhold sufficient funds from any payment to the GC to cover your claim. An owner who pays the GC in full after receiving your notice risks being held personally liable for your unpaid amount. That is the power of being secured — you lock your position at the top of the tower before the owner has the chance to drain the glass.
For a full breakdown of notice requirements, deadlines, and the filing process, see:
On public projects, where property cannot be liened, the equivalent secured position is achieved through a payment bond claim under the Illinois Public Construction Bond Act (30 ILCS 550) — a direct claim against the surety company that guarantees payment even if the GC defaults. See our Payment Bond Claims guide for full requirements.
The Mistakes That Drop You to the Bottom
Most contractors who end up unsecured did not lose their position in court. They lost it by missing a step before anyone knew there was a problem:
- Waiting until payment is overdue to serve the Section 24 notice — by then the owner may have already paid out the GC in full
- Serving notice on the GC instead of the property owner
- Signing an unconditional lien waiver before payment has actually cleared
- Miscalculating the last furnishing date and missing the lien recording window
- Assuming a demand letter or email preserves statutory deadlines — it does not
- Failing to obtain a copy of the payment bond at the start of a public project
Get to the Top of the Tower Before the Problem Starts
The contractors who recover on troubled projects are not always the ones with the strongest legal arguments. They are the ones who did the compliance work from day one — served the right notices, recorded the lien on time, and secured their position at the top of the tower before anyone knew the bottle was running low.
Emalfarb Law helps Illinois contractors, subcontractors, and suppliers get secured from the first day of work — and enforce those rights when payment does not come.
