Searched questions
Plain answers California operators actually type.
- How long do I have to serve a California preliminary notice?
- Twenty days from first furnishing labor or materials — not from the contract date and not from the first invoice. Civ. Code §8200.
- What if I serve the 20-day notice late?
- §8204 keeps lien rights only for work in the 20 days before you served, plus after. Earlier work is unsecured.
