Conditional vs. unconditional lien waivers

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.

California lien and notice deadlines are strict and fact-specific: “completion” alone can be triggered by actual completion, the owner’s occupancy or use, or a 60-day cessation of labor.
