Mechanic's Liens: Securing Payment in Construction

What Is a Mechanic's Lien?

A mechanic's lien (also called a construction lien or materialman's lien) is a legal claim against a property by a contractor, subcontractor, or supplier who provided labor or materials for improvements to that property but was not paid. The lien attaches to the real property itself, giving the claimant a secured interest that can ultimately force a sale of the property to satisfy the debt.

Mechanic's liens are one of the most powerful payment remedies available in construction.

Who Can File a Mechanic's Lien?

  • General contractors
  • Subcontractors
  • Sub-subcontractors (in many states)
  • Material suppliers
  • Equipment rental companies (in some states)
  • Architects and engineers (in some states)
  • Laborers

How the Process Works

  1. Preliminary notice — Many states require a preliminary notice early in the project to preserve lien rights
  2. Non-payment occurs — The claimant performs work or delivers materials but is not paid
  3. Lien filing — The claimant records the lien with the county recorder within the statutory deadline
  4. Enforcement deadline — The claimant must file a lawsuit to enforce the lien within a separate statutory period
  5. Resolution — The lien is either satisfied through payment, released by agreement, or enforced through foreclosure

Critical Deadlines

Missing a deadline can permanently destroy your lien rights:

  • Preliminary notice: Often required within 20-30 days of first furnishing labor or materials
  • Lien filing: Typically 60-120 days after completion (varies greatly by state)
  • Enforcement lawsuit: Usually 6-12 months after lien recording

What Property Owners Should Know

A mechanic's lien can cloud your property title and prevent sale or refinancing. To protect yourself:

  • Require lien waivers with each payment
  • Verify that subcontractors are being paid by the general contractor
  • Consider joint check agreements for major subcontractors

When to Consult a Lawyer

Mechanic's lien laws are highly state-specific with strict deadlines. Consider consulting a construction attorney at the first sign of a payment dispute to preserve your rights.
