Check California progress payment lien releases by claimant, payment status, through-date and exceptions before paying for a home build or renovation.
Before a progress payment on a California home build or renovation, collect conditional lien releases from the claimants being paid. Follow up with unconditional releases after they receive payment, as CSLB recommends. A general contractor’s release does not establish that subcontractors or suppliers were paid.
For each installment, match the releases to the claimant, payment stage and covered work. Keep them with your construction costs and payment plan.
Ask the builder for an updated list of subcontractors, laborers and suppliers. Compare it with invoices and preliminary notices you received to identify whose work or materials the installment covers. CSLB recommends tracking these parties and obtaining releases from those being paid.
Check each release’s claimant name, customer, owner and job location. The customer may be the general contractor who hired a subcontractor; it is not necessarily the homeowner. The claimant or its authorized agent must sign the release.
An unpaid subcontractor or supplier may still assert a mechanics lien after the owner has paid the general contractor, creating a risk of paying twice. CSLB describes that risk.
Choose the official progress form according to the claimant’s payment status:
| Claimant’s payment status | Progress-payment form |
|---|---|
| Awaiting payment, including a check that has not cleared | Conditional Waiver and Release on Progress Payment, §8132 |
| Has received the payment | Unconditional Waiver and Release on Progress Payment, §8134 |
The conditional form becomes effective when the claimant receives payment from the institution on which the identified check is drawn. Match the check’s maker, amount and payee to the planned payment.
The unconditional form warns that it is enforceable against a signer even without payment. Do not ask an unpaid claimant to sign it merely to get a check issued. Its exceptions still apply.
Keep evidence that the claimant received payment. CSLB identifies a claimant-endorsed check paid by the bank, or the claimant’s written acknowledgment, as evidence supporting a conditional release. A cleared check payable only to your builder does not demonstrate payment to its supplier.
Compare the payment request with the contract schedule and documented scope, including allowances. Confirm that the billed work was performed and materials delivered.
The through-date identifies the cutoff for covered labor, services, equipment and materials. It is separate from the signature date. Review it against the billing period and delivery records as well as the installment amount.
Hypothetical example: A request covers work through August 15, but a supplier’s release runs only through July 31. That release does not establish coverage for ordinary deliveries made August 1–15. Ask for an explanation and documentation matching the intended coverage.
Check change orders separately. Both progress forms release rights arising from written change orders fully signed by the parties before the claimant signs the release, unless listed as exceptions. Do not assume that calling work an “extra” keeps it outside the release. Read the progress-form language.
Read the printed exceptions even when the fill-in spaces are empty:
The conditional progress form also provides spaces for dates and amounts of earlier conditional releases for which payment was never received. Reconcile those entries with the payment ledger. Review the conditional form’s exceptions.
Track each exception as an open item. Record the amount, reason and expected resolution before marking that claimant’s account fully cleared.
A final release has broader scope and no through-date. The conditional final-payment form, §8136, depends on payment; the unconditional final-payment form, §8138, states that the claimant has been paid in full. Their printed exception concerns disputed extras with a stated amount; they do not carry the progress forms’ retention exception.
Use final-payment releases only for final payment to that claimant. A supplier might receive its final payment while other construction continues. Reconcile its remaining balance, retention and disputed extras before requesting a final release.
Your construction progress payment documents should connect the requested work, each relevant claimant’s release, prior payment evidence and every unresolved exception. Resolve missing signatures, inconsistent dates or unexplained balances before treating the paperwork as complete.
If a claimant disputes payment or the release’s scope, consult a California construction attorney before deciding to withhold money or rely on the document. Keep the reconciled packet with your project records; our homeownership project guides cover related planning decisions.
Yes. An unpaid subcontractor may still assert a mechanics lien even when the owner has paid the general contractor. The contractor’s release does not release every other claimant’s rights. CSLB explains the risk.
The statutory conditional progress form takes effect when the claimant receives payment from the financial institution on which the identified check is drawn. It does not depend on a later unconditional release. CSLB recommends collecting unconditional releases after claimants are paid. Conditional form; CSLB follow-up guidance.
CSLB’s waiver and release page links all four forms. Select progress or final payment for the particular claimant, then conditional or unconditional according to payment status.
