I will be receiving payment tomorrow how can I file or prepare documents for a mechanics lien release
California mechanics lien releases are done much in the same way that California mechanics liens are - a lien release a pretty simple document that must be filled with relevant claim and property information. Once payment has been made, a claimant can execute and then record that lien release (or provide it to the paying party for them to record).
You can find a free, downloadable template for a CA lien release here: California Mechanics Lien Release Form.
