California Lien Waivers

All 4 statutory forms under Civil Code §§8132–8138. Flags non-statutory waivers and unconditional waivers signed before payment clears — the two biggest ways contractors lose lien rights.

W-9 Forms (IRS)

Catches missing TIN fields, incorrect entity types, and backup withholding flags that delay contractor payments.

ACORD 25 Certificates of Insurance

Verifies California minimum general liability ($1M), workers compensation coverage, additional insured endorsements, and policy expiration dates.

Safety Data Sheets

OSHA HazCom 2012 / GHS 16-section format. Flags missing critical sections (hazard identification, first aid, exposure controls) and outdated pre-GHS documents.

Your documents never touch our servers

Documents are processed entirely in memory and immediately discarded. Only risk scores and summaries are saved — never your original text, never your clients' information.

Bilingual output (English + Mexican Spanish)

Every analysis is delivered in both languages. Share results with your entire crew — no translation step, no miscommunication.

Backed by California Civil Code, not just AI guesses

AI output is validated against hard statutory rules. Non-statutory lien waivers automatically flag as High risk — even if the AI missed it.

Flat-rate pricing. No surprises.

$2 per page plus a small AI processing fee. No subscriptions, no minimums, no hidden fees. Pay only for the documents you scan.

Usually under 30 seconds

On-device OCR with ML Kit for instant text extraction. Server-side Tesseract fallback when needed. Most analyses finish before you've refilled your coffee.

Submit documents any way you work

Camera, file upload, text paste, email (scan@email.paidwrite.app), Chrome extension, or DocuSign and Dropbox Sign webhooks.

Frequently asked questions

The questions California subcontractors ask before their first scan.

Is a California lien waiver legally binding once signed?
Yes. A California lien waiver takes effect based on Civil Code §§8132–8138. An unconditional waiver is binding the moment you sign — even if payment never clears. A conditional waiver only takes effect once the paying party's check actually clears. Signing the wrong form before payment can waive your lien rights permanently.
What is the difference between a conditional and unconditional lien waiver?
A conditional waiver takes effect only after payment clears. An unconditional waiver takes effect immediately on signature, regardless of whether payment arrives. Contractors should never sign an unconditional waiver before payment clears. PaidWrite flags this automatically.
Does PaidWrite work for contractors outside California?
Lien waiver analysis is California-specific (Civil Code §§8132–8138). W-9 analysis is federal and applies anywhere in the US. ACORD 25 Certificate of Insurance analysis and OSHA Safety Data Sheet analysis are nationally applicable. Other state lien waiver rulesets are on the roadmap.
How accurate is the analysis?
Every analysis runs AI output through a layer of hard California statutory rules — so common compliance errors (non-statutory lien waiver forms, missing workers comp, missing W-9 TIN, SDS sections out of spec) are caught deterministically, not left to AI judgement alone. For any document flagged High or Critical, we recommend a quick attorney review before signing.
Are my documents stored on your servers?
No. Documents are processed entirely in memory and immediately discarded. We save only the analysis results (risk scores, summaries). We never retain the original document text or any PII.
How much does a document review cost?
$2 per page, plus a small AI processing fee. No subscription, no minimum.
