The California Release of Mechanic Lien is a legal document that is used to release a mechanic's lien from a particular property. A mechanic's lien is a security interest in a property that is granted to a contractor, subcontractor, or laborer who has provided labor or materials for the improvement of real estate. The California Release of Mechanic Lien is a form that must be completed and filed with the county recorder in order to legally release the lien from the property. The form includes the legal description of the property, the name of the party who holds the lien, and the name and address of the party who is paying the lien. The form must be signed by the lien holder in order to be valid. There are two types of California Release of Mechanic Lien: the full release and the partial release. The full release releases all claims against the property. The partial release releases only specific claims against the property. Both types must be signed and recorded with the county recorder in order to be legally valid.
