Conditional vs. unconditional lien waivers
One word on the form decides who carries the risk of a bounced check. Here's the two-question test.
California’s four statutory lien waiver forms (Cal. Civ. Code §§ 8132–8138) split along two axes: conditional vs. unconditional, and progress vs. final. The progress/final choice is easy — it’s whichever payment this is. The conditional/unconditional choice is where subs get hurt.
The core difference
- Conditional — effective only if and when the payment described actually reaches you. Check bounces? Payment never sent? Your lien rights are untouched.
- Unconditional — effective the instant you sign, period. If the payment falls through afterward, your lien rights for that work are already gone.
The two-question test
- 1. Has the money cleared my account?Cleared — not promised, not “processing.” If no → conditional. If yes → unconditional is safe.
- 2. Progress payment or final? Mid-job → progress (releases only work through the stated date). Closing out the job → final (releases everything).
That’s the whole decision. The dangerous square is unconditional-before-clearing— and it’s exactly the one GCs most often push, because it moves all the payment risk onto you.
The check-swap, done right
The standard, fair exchange: you hand over a conditional waiver, the GC hands over the check. Once the check clears, the conditional waiver takes full effect — the GC ends up with exactly the release it wanted, and you were never exposed in between. If a GC insists on unconditional-before-payment, they’re not asking for paperwork; they’re asking you to finance their risk.
Watch the details either way
- Through-date — a progress waiver releases work through this date. Make sure it matches the billing period.
- Amount — should match the payment, not the contract total.
- Statutory form— custom waiver forms with extra release language are generally unenforceable (§ 8124), but don’t sign one anyway; insist on the statutory text.
