Frequently asked questions about mechanics lien filing

Everything you need to know about how to file a mechanics lien on property

What is a mechanics lien and how does mechanics lien filing work?

A mechanics lien (also called a construction lien or contractor lien) is a legal claim against a property that secures payment for work performed or materials supplied. Filing one creates a security interest in the property. Our full service handles the whole process, from document preparation to recording with the county.

Who can file a mechanics lien on property?

Anyone who provides labor, materials, or services to improve real property can file a mechanics lien. This includes general contractors, subcontractors, material suppliers, equipment rental companies, architects, engineers, and laborers. We help all of them file a lien when payment is overdue.

How do I file a construction lien? What's the process?

To file one, you'll need to: (1) Send preliminary notices if your state requires them, (2) Prepare the lien with property and project details, (3) Record it with the county recorder, and (4) Serve notice on the property owner. We can handle these steps for you.

What are the deadlines to file a mechanics lien?

Lien deadlines vary by state. They typically fall 30 to 120 days after you last provided labor or materials. If you miss the deadline, you lose your right to file. Our platform tracks these dates for you and sends reminders before they pass.

Are lien forms different in each state?

Yes. Every state has its own mechanics lien laws. Some require specific language, notarization, or preliminary notices before you can file. We use the correct form for your state.

How much does it cost to file a mechanics lien?

Self-serve starts at $99. We prepare your mechanics lien, and you sign it and record it with the county yourself, so you also pay the county's recording fee. Full service starts at $299. We prepare the lien, record it with the county, and serve every required party, with standard recording fees included. Unusually high county fees may cost extra, and we'll tell you before you pay.

What's the difference between a mechanics lien and a construction lien?

They are different names for the same legal tool. Some states call it a "mechanic's lien," others a "construction lien" or "contractor's lien." Whatever the name, it secures payment for work performed on real property. We handle all of them.

Can I file a mechanics lien as a subcontractor?

Yes. Subcontractors can file a mechanics lien even without a direct contract with the property owner. It is one of the strongest protections in construction law. We help subcontractors file a lien when the general contractor hasn't paid.
