  • Bond off lien (obtain surety bond to release lien)
  • Sue to remove lien and for damages if lien is fraudulent

Frequently Asked Questions
Yes. You can withhold payment for incomplete or defective work. However, only withhold amount reasonably related to cost of defects. If contractor threatens to file mechanics lien, document defects carefully (photos, expert opinions, repair bids) to defend against lien. Best practice: withhold final payment (typically 10%) and demand contractor return to make repairs before releasing final check.
Unlicensed contractors cannot enforce contracts or collect payment (B&P § 7031). You can refuse to pay and sue for return of any payments made, regardless of work quality. Verify license at CSLB.ca.gov. If contractor was unlicensed, you have strong defense to any mechanics lien or payment demand. Report to CSLB and consider criminal complaint for contracting without license.
Statute of limitations: 4 years for breach of contract (from date you discovered or should have discovered defect); 3 years for fraud; 10 years for latent defects in residential construction (CCP § 337.15). For patent (obvious) defects like poor tile work or misaligned cabinets, clock starts when work completed. For latent defects like hidden plumbing leaks or foundation issues, clock starts when discovered. Act quickly—don't wait years to sue.
