How long do I have to file a mechanic's lien?
It depends on your state. Common deadlines run 60, 90 or 120 days from the date you last furnished labor or materials to the project. For example, California generally requires recording within 90 days of completion (or 60 days after a notice of completion). Always confirm your state's exact period.
What is a preliminary notice and why does it matter?
A preliminary (or pre-lien) notice is a written notice sent early in the project — often within 20 days of first furnishing — that preserves your right to later file a lien. In many states, failing to serve the preliminary notice bars your lien entirely, even if you record within the filing deadline.
Do subcontractors and suppliers have different deadlines?
Often yes. Many states set different notice and filing deadlines depending on whether you are the prime (general) contractor, a subcontractor, or a material supplier. Suppliers frequently have shorter notice windows. Check the rule for your specific role.
What happens if I miss the mechanic's lien deadline?
If you miss the recording deadline your lien rights are lost, though you may still pursue a breach-of-contract claim or a bond claim on a bonded or federal (Miller Act) project. Lien deadlines are strict and generally not extendable.
