A California mechanic’s lien is used to seek compensation for unpaid labor or materials contributed to a job site by a tradesperson or supplier. Mechanic’s liens are filed by the unpaid worker (the “claimant”) with the recorder’s office in the county where the labor or materials were supplied. Once recorded, the claimant may enforce the lien through a lawsuit to secure an interest in the property itself for the amount to which they’re entitled.

A mechanic’s lien will obstruct the property title and make it difficult for the owner to sell or obtain additional financing. This factor incentivizes owners to resolve the matter by promptly paying the claimant.
