Lien Waivers and Final Payment: Completing Your Project Safely

What Are Lien Waivers?

A lien waiver is a legal document where a contractor or supplier waives their right to file a mechanics lien against your property for the amount specified. They're essential for protecting your property title.

California's Four Lien Waiver Types

1. Conditional Waiver on Progress Payment

Used during the project. The waiver becomes effective only when the contractor actually receives payment. Use this before releasing each milestone payment.

2. Unconditional Waiver on Progress Payment

Provided after payment clears. This confirms receipt and waives lien rights for that specific amount.

3. Conditional Waiver on Final Payment

Used for final payment. Like conditional progress waivers, effective only upon actual payment receipt.

4. Unconditional Waiver on Final Payment

The ultimate protection. Waives all lien rights upon project completion and final payment.
