We guide every client through a proven three-step process:

  1. Project Compliance — complete our intake form and project data sheet to secure your receivables from the outset

  2. Track the Project — we manage deadlines for Notice to Owners and Preliminary Notices so your rights are never forfeited

  3. Lien Filing & Enforcement — when notices aren’t enough, we file and enforce mechanic’s liens and bond claims with real legal weight

A Network of Attorneys & Local Providers

Every state has its own lien statutes, deadlines, notice formats, and filing requirements. No algorithm can replace an attorney who knows the local rules and the county recorder's office by name.

Why Software Falls Short

  • Generic templates that don't account for state-specific statutory language
  • No one reviews whether your claim is actually legally defensible
  • Can't escalate to enforcement or litigation when a debtor ignores your filing
  • Misses nuances like county-level recording rules and local service requirements

The Power of a Network

  • Local attorneys who know each state's lien statutes inside and out
  • On-the-ground notice providers who handle service, recording, and county-specific requirements
  • Every filing is attorney-reviewed — a legal claim, not just a document
  • Seamless escalation to enforcement and litigation when payment isn't made

Who We Represent

Our network of construction attorneys and local providers protects every party in the construction chain — with the state-specific knowledge that software can't match.

Contractors

Aggressive enforcement to ensure your project stays profitable. We file and enforce liens that protect your receivables on every job.

Subcontractors

Protecting your rights when the payment chain breaks. We ensure your preliminary notices and lien filings meet every state-specific deadline.

Material Suppliers

Securing high-volume receivables across state lines. We protect your payment rights even when you have no direct contract with the property owner.

Frequently Asked Questions

Common questions about construction payment protection and Mechanic's Lien filing.

What is a Mechanic's Lien and how does it protect my construction payment?
A Mechanic's Lien is a legal claim against a property that secures payment for labor, materials, or services provided during construction. Filing a lien creates a security interest in the property itself, giving you powerful leverage to collect unpaid invoices. Each state has specific deadlines and requirements that must be followed precisely, or you risk losing your right to file.
How does National Lien & Bond differ from online lien filing software?
We are a network of construction attorneys and local notice providers — not software. Every state has different lien statutes, deadlines, notice formats, and county-level filing requirements. Software uses generic templates and can't review whether your claim is legally defensible. Our network gives you local attorneys who know your state's specific rules, on-the-ground providers who handle service and recording, and the ability to escalate to enforcement and litigation when a debtor doesn't pay. You get one point of contact with the power and knowledge of the entire network behind you.
What is the Federal Miller Act and when does it apply?
The Federal Miller Act (40 U.S.C. §3131-3134) requires contractors on federal construction projects over $150,000 to obtain payment bonds. If you are a subcontractor or supplier on a federal project and have not been paid, you can file a claim against the payment bond to recover what you are owed. Specific notice and timing requirements apply.
Do I need to send a Preliminary Notice before filing a lien?
In many states, yes. Preliminary notices are required to preserve your right to file a Mechanic's Lien later. The deadlines and requirements vary significantly by state. Missing a preliminary notice deadline can permanently extinguish your lien rights, which is why proactive compliance from the start of a project is critical.
How quickly do I need to act to protect my payment rights?
Construction payment deadlines are strict and unforgiving. Depending on your state, you may have as few as 30 days to send required notices or file a lien after your last day of work. Missing a deadline by even one day can eliminate your right to payment. Contact us immediately if you have an unpaid invoice on a construction project.

Deadlines Are Unforgiving

Every Day You Wait Is a Day Closer to Missing Your Deadline

Construction lien deadlines are strict and unforgiving. Once they pass, your right to payment may be gone forever.
