Collections: Mechanics’ Liens,
Stop Payment Notices and Bond Claims

The right to pursue the collection of a construction-related debt through a mechanics’ lien is specifically guaranteed to contractors, subcontractors, suppliers and others by the California State Constitution, Article XIV, sec 3. The right to a stop payment notice and a payment bond claim derive from this right. Over the years, numerous statutes and hundreds of court cases have further refined these basic rights.

The evolution of these laws has resulted in an obstacle course of paperwork and service requirements. These include County Recorder filings and Superior Court filings – each with its own unique documentation requirements, deadlines and mandatory service rules. Claimants and their attorneys must properly complete the appropriate documents, serve those documents in a timely manner, maintain proof of service, record other documents as necessary and bring suit within proper timelines. Any single misstep along the way can be 100% fatal to the entire claim.

Pursuing your mechanics’ lien, stop payment notice and bond claim remedies should be trusted to attorneys who thoroughly understand this complex and often confusing area of law. There is no substitute for experience.
