Hiring a contractor should be simple. You agree on a price, the contractor finishes the work and everyone moves on. But if someone on the job does not receive payment, you could face a legal claim against your home, sometimes even after you pay your general contractor.
Defining the mechanic’s lien
A mechanic’s lien gives contractors, subcontractors and suppliers a legal claim against your property for unpaid labor or materials. The lien becomes part of the public record and can cloud your title. That can delay a sale or refinance until you resolve the debt.
Disputes like these are common in real estate matters, and they often turn on small procedural details. A court may invalidate a lien if the claimant misses a notice requirement or filing deadline.
When can a contractor file a lien?
Under Minnesota law, a contractor with a direct contract with you generally has 120 days after the last work or materials to file a lien statement with the county and serve you with a copy. If the claimant misses that window, they typically lose the right to assert a lien.
Subcontractors and suppliers who do not contract directly with you face an added step. They must serve you with a pre-lien notice within forty-five days after they first provide labor or materials. A claimant who skips this notice generally cannot claim a lien.
How can you protect your home?
A few habits can reduce your risk. Before you make final payment, you should:
- confirm that your general contractor has paid up subcontractors and suppliers
- request signed lien waivers from everyone who worked on your project
- keep contracts, receipts and records of completion dates
If a lien appears even though you paid, you may be able to challenge it in court or post a bond to clear your title.
Understanding your legal options
Mechanic’s lien rules are complex, and missed deadlines can change your rights. A Minnesota real estate attorney can review your contract, any lien notices and your options for protecting your title.
