Collecting lien waivers from subcontractors
2026-09-04 · 6 min read

Paying a subcontractor does not clear the property. Waivers are how a general turns payments into a clean title, and the routine below is the one that survives a closeout audit.
Why a general collects them at all
A general contractor that pays a subcontractor is not automatically safe. If that sub does not pay its own supplier, the supplier can still reach the property, and the owner will look upward. Waivers are how a general converts “we paid” into “nobody below us has a claim”, and how a lender gets comfortable funding the next draw.
That is also why the request is not personal. A general asking for a waiver with every application is doing the job the title company will ask it to prove. The negotiation is about which waiver, not whether.

The exchange routine that works
- Application in by the cut-off, with a conditional waiver attached for the net payable.
- General certifies; lender funds; cheques go out.
- Sub confirms funds cleared and returns the unconditional waiver for the amount that cleared.
- General files both against the application number, not against the month.
- Retainage waiver held back until the retention cheque itself clears.
Filing against the application number is the step that saves the closeout. When a title company asks for the waiver chain twelve months later, an application-numbered file reconciles in an afternoon; a folder of PDFs named by month does not.
Lower tiers are where the risk lives
A general's exposure is not its direct subcontractors — those it pays and documents. It is the sub-subs and the material suppliers two tiers down, who have lien or bond rights and no relationship with anyone the general talks to weekly.
Two habits close most of it: ask each first-tier sub for a list of its own suppliers on that job at award, and collect waivers from any supplier that served a preliminary notice. Where a supplier is genuinely at risk, a joint check agreement is cheaper than the lien it prevents.
| Tier | Who signs | Trigger |
|---|---|---|
| First | Subcontractors | Every application |
| Second | Sub-subs | Named on a first-tier list |
| Supplier | Material suppliers | Any preliminary notice received |
| Rental | Equipment lessors | Where state law gives lien rights |
When a sub is right to refuse
A subcontractor should refuse an unconditional waiver before payment clears, a through date past the billing period, and a final waiver while retainage is outstanding. None of those refusals is unreasonable, and a general that treats them as obstruction is telling you something about its own cash position.
The workable answer in all three cases is the conditional version now and the unconditional version on confirmation. Keep the exchange on a schedule and it stops being a monthly argument.
On a federal job, waivers do not replace the Miller Act notice. A claimant below the first tier still owes the prime written notice within 90 days of its last labour or material.
