One missed deadline can cost you everything.

When a GC doesn't pay, your only legal protection is a mechanic's lien filed against the property. But California law gives you a hard deadline — miss it, and you lose all legal leverage. Forever.

Most specialty subs track these dates on a spreadsheet — if they track them at all. That works until the month you're slammed with three new jobs, a GC goes silent on a $150,000 invoice, and you find out the lien window closed two weeks ago.

LienLock isn't a better spreadsheet. It reads your actual paperwork — contracts, invoices, change orders — extracts the critical dates, and watches every deadline automatically. You don't change how you work. You just forward your documents.


You forward the paperwork. We do the rest.

1

Forward whatever you have

Email us your contracts, invoices, change orders — PDFs, scans, whatever format. No forms to fill out. No data to enter. Just forward and move on.

2

We read and extract

Our AI parses your documents and pulls out what matters — GC name, property address, contract dates, invoice amounts, last date of work. The calendar builds itself.

3

Alerts before anything closes

Escalating alerts at 60, 30, 14, 7, and 1 day out. Weekly risk digest every Monday. You always know exactly where every job stands.

4

You make the call

We flag the window. Your attorney or lien service handles the filing. We make sure you know exactly when to call them — before it's too late.


Simple pricing. No contracts.

Start with a one-time audit. Stay for the peace of mind.
