A mechanic's lien is a legal claim a contractor, subcontractor, or supplier can place on your property if you don't pay them for work or materials
When someone does work on your house or supplies materials for a construction project and doesn't get paid, they can file a mechanic's lien against your property. This lien gives them a legal right to be paid from the proceeds if you sell the property, refinance it, or the lender forecloses. The lien stays on your title until the debt is satisfied, and it can prevent you from selling or refinancing until it's resolved.
The person filing the lien doesn't have to sue you first — they can place the lien directly on your property record. This makes mechanic's liens powerful tools for contractors and suppliers, because it gives them security without going to court. For you as a property owner, it means an unpaid bill for construction work can become a serious title problem that affects your ability to borrow money or transfer ownership.
Key Takeaways
- A mechanic's lien is a legal claim placed on your property when a contractor, subcontractor, or material supplier is not paid for work or materials they provided.
- The lien holder can force a sale of your property to collect what they are owed, even if you have already paid the general contractor.
- Most states require the lien filer to give you written notice within a specific timeframe — usually 30 to 45 days after starting work — or they lose the right to file.
- You can remove a lien by paying the debt, posting a bond, or filing a dispute if the claim is invalid or the amount is wrong.
- Mechanic's liens typically expire after a set period — often one to three years — if the lien holder does not file a lawsuit to enforce it.
Who can file a mechanic's lien and when
Any contractor, subcontractor, laborer, or material supplier who provides work or materials for a construction project on your property can file a mechanic's lien. This includes the general contractor you hired directly, but also electricians, plumbers, concrete suppliers, and workers hired by the general contractor — even if you never signed a contract with them or knew they were coming.
The lien filer must act within a important date set by your state. Most states require notice to be given within 30 to 45 days after the work begins or materials are first delivered. Some states require the notice to be sent to you specifically; others allow it to be posted on the property or filed with the county. If the lien filer misses this important date, they lose the right to file a mechanic's lien, though they can still sue you for payment through regular court proceedings.
How a mechanic's lien affects your property
Once a mechanic's lien is filed and recorded with your county, it becomes part of your property's title. When you try to sell the property, the title company will discover the lien during the title search. You cannot close the sale without paying off the lien or getting the lien holder to agree to release it. The same problem occurs if you try to refinance — the lender will require the lien to be removed before they will fund the loan.
If you ignore the lien and do not pay, the lien holder can file a lawsuit to foreclose on the lien. This means they can force a sale of your property to collect what they are owed. The lien holder's claim is paid from the sale proceeds before you receive any money, and in some cases before the mortgage lender is paid in full. This is why mechanic's liens are taken seriously by lenders and title companies.
Notice requirements and your right to know
Most states require the person filing a mechanic's lien to give you written notice before or shortly after they file the lien with the county. The notice must include the lien filer's name, the amount claimed, a description of the work or materials provided, and the property address. This notice is your opportunity to verify that the claim is accurate and that the work was actually done or materials were actually delivered.
The timing of this notice varies by state. Some states require notice to be sent to you within 30 days of the lien being filed; others require it before the lien is filed. A few states allow notice to be posted on the property instead of mailed to you. If you do not receive notice, you may still have a lien on your property, so it is worth checking your county records periodically if you have had construction work done.
How to remove or dispute a mechanic's lien
The most straightforward way to remove a lien is to pay the amount claimed. Once you pay, the lien holder must file a release of lien with the county, which removes the claim from your title. Get the release in writing before you hand over money, and make sure it is recorded with the county — do not rely on a verbal promise.
If you believe the lien is invalid or the amount is wrong, you can file a lawsuit to contest it. You might dispute a lien if the work was never completed, the materials were never delivered, you already paid the general contractor (who was supposed to pay the subcontractor), or the amount claimed is inflated. The burden of proof is on you to show the lien is improper, so gather documentation — contracts, invoices, proof of payment, photos of work — before you file.
Another option is to post a bond. Some states allow you to file a bond for the amount of the lien, which removes the lien from your property title while the dispute is resolved. The bond acts as security for the lien holder. If you win the dispute, the bond is returned to you; if you lose, the bond is paid to the lien holder. Bonds are typically more expensive than paying the debt outright, so this option is most useful when you genuinely believe the lien is invalid.
How long a mechanic's lien lasts
A mechanic's lien does not stay on your property forever. Most states set an expiration date — typically one to three years from the date the lien is filed — after which the lien is void if the lien holder has not filed a lawsuit to enforce it. Some states give longer periods, and a few allow the lien holder to renew the lien before it expires.
The expiration date varies significantly by state, so check your state's law or ask a title company what applies to your property. Even if a lien has technically expired, it may still appear on your title record until it is formally released or removed by court order. This can still cause problems when you try to sell or refinance, so it is worth resolving liens proactively rather than waiting for them to expire.
Protecting yourself from mechanic's liens
If you hire a contractor for work on your property, you can reduce the risk of mechanic's liens by taking a few steps. First, pay the general contractor only after confirming that all subcontractors and suppliers have been paid. Ask the contractor for lien waivers — signed statements from subcontractors and suppliers confirming they have been paid — before you release final payment.
Second, require the contractor to provide proof of payment to subcontractors and suppliers, or ask them to have those parties sign lien waivers directly. Third, if you are paying for materials or work directly, pay the supplier or worker directly rather than giving money to the general contractor to pass along. Fourth, check your county records periodically during and after the project to see if any liens have been filed. If you spot a lien early, you can contact the lien filer and resolve the issue before it becomes a title problem.
Frequently Asked Questions
Can a mechanic's lien be filed if I already paid the general contractor?
Yes. If you paid the general contractor but they did not pay their subcontractors or suppliers, those parties can still file mechanic's liens against your property. This is why it is important to get lien waivers from all subcontractors and suppliers before you release final payment to the general contractor.
Does a mechanic's lien take priority over my mortgage?
In most states, mechanic's liens filed during construction take priority over a mortgage taken out after construction began, even if the mortgage was recorded first. However, if your mortgage was in place before construction started, the mortgage typically has priority. The exact rules vary by state, so check with a title company or attorney in your area.
What if the lien amount is wrong or inflated?
You can file a lawsuit to contest the lien and ask the court to reduce or eliminate it. You will need to prove that the amount claimed is inaccurate — for example, by showing that only part of the work was completed or that you already paid part of the bill. Gather all contracts, invoices, and payment records before you file.
Can I sell my house if there is a mechanic's lien on it?
You cannot close a sale while a mechanic's lien is on the title. The title company will not issue a title insurance policy, and the buyer's lender will not fund the loan. You must pay off the lien, get the lien holder to release it, or post a bond before the sale can proceed.
How do I know if a mechanic's lien has been filed against my property?
Check your county recorder's office or search the county's online records database. You can also ask a title company to run a title search, which will show any liens on your property. If you had construction work done, it is worth checking periodically during and after the project.
