Private Works — 1-Year Suit Deadline
Under Minnesota law, a mechanic lien must be enforced by filing suit within 1 year of the mechanic lien claimant's last performance on the project. This deadline applies to all claimant types — general contractors, subcontractors, materialmen, and sub-subcontractors.
If the mechanic lien claimant fails to initiate suit within this one-year period, the mechanic lien expires and becomes unenforceable. The claimant loses all mechanic lien rights and must pursue other legal remedies such as breach of contract.
Public Works — Bond Claim Suit Deadline (§574.26)
On public works projects, suit on the payment bond must be filed within 1 year of the claimant's last delivery of labor and materials to the project. M.S.A. §574.26 et seq.
Before filing suit, the claimant must have served the required written notice of claim to the contractor and surety within 120 days of last performance. Failure to serve this notice bars the bond claim suit.
Payment Bond Requirements on Public Projects
Minnesota requires performance and payment bonds for the full amount of the contract on public works projects with limited exceptions. M.S.A. §574.26.
The payment bond must list the contractor's and surety's address. If the bond does not list these addresses, notice of payment bond claim need not be given — providing a limited exception to the 120-day notice requirement.
Notice Prerequisites Before Suit
On private works, the claimant must have satisfied all preliminary notice requirements (statutory contract notice for contractors, pre-lien notice for subcontractors) and must have served the certified mail notice and recorded the mechanic lien within 120 days of last performance.
On public works, the claimant must have served written notice to the contractor and surety within 120 days of last performance before filing suit on the payment bond.
Automatic Mechanic Lien Expiration
A Minnesota mechanic lien that is not enforced by filing suit within 1 year of last performance automatically expires by operation of law. The claimant loses all mechanic lien rights and must pursue alternative remedies.
It is critical to calendar this deadline carefully — once the mechanic lien expires, the security interest in the property is lost permanently.
