A lien is a legal claim against property that secures payment of a debt. The lien gives the creditor a right to have the property sold to satisfy what is owed if the debtor does not pay. Liens attach to real estate, vehicles, bank accounts, business assets, and even personal injury settlements. They are common, and they can exist without the owner realizing it, which is why title searches and public records matter.
Consensual and Non-Consensual Liens
The first distinction is whether the property owner agreed to the lien. A mortgage is a consensual lien: the borrower signs a promissory note and a security instrument, and the lender records the lien. A car loan works the same way, with the lien noted on the certificate of title. Non-consensual liens arise by operation of law. Tax liens, mechanic's liens, and judgment liens fall into this group. The table below compares the main types.
| Lien type | How it arises | Typical property |
|---|---|---|
| Mortgage or deed of trust | Agreement with a lender | Real estate |
| Vehicle lien | Agreement with a lender, shown on title | Cars, trucks, boats |
| UCC security interest | Security agreement under Article 9 | Business equipment, inventory, receivables |
| Federal or state tax lien | Unpaid taxes, filed by the government | Broad; reaches most property |
| Mechanic's lien | Unpaid work or materials on a property | Real estate improved by the work |
| Judgment lien | Recorded judgment from a lawsuit | Real estate, sometimes personal property |
How a Lien Is Perfected
Creating a lien and making it enforceable against other creditors are two different things. Perfection is the step that gives the creditor priority over later claims and, in many cases, over a bankruptcy trustee. The method depends on the property. Real estate liens are recorded with the county recorder or registrar of deeds. Vehicle liens are noted on the certificate of title issued by the state motor vehicle agency. Security interests in most business assets are perfected by filing a UCC-1 financing statement with the state, under Article 9 of the Uniform Commercial Code. Federal tax liens are filed with the state and recorded with the county, and the IRS files a public notice of federal tax lien.
Priority: Who Gets Paid First
When several liens exist on the same property, priority usually follows the first to record or perfect, often summarized as first in time, first in right. That general rule has important exceptions. A purchase money mortgage used to buy the property may take priority over an earlier judgment lien. Real property tax liens often have super-priority over private liens. Mechanic's liens may relate back to the start of the work, which can give them priority over a mortgage recorded after work began. Federal tax liens have their own priority rules and can reach a broad range of assets. Because priority determines who gets paid and who does not, it is often the central issue in a dispute.
Tax Liens
When a taxpayer does not pay, federal law allows a lien to arise in favor of the United States on all property and rights to property belonging to the taxpayer. The IRS explains the process on irs.gov. The lien arises by operation of law, and the IRS files a public notice of federal tax lien to protect its priority against other creditors. A federal tax lien can affect the ability to sell property, borrow against it, or obtain credit. The IRS offers collection alternatives, including payment plans and offers in compromise, and a lien can be released once the debt is paid or otherwise resolved.
Mechanic's Liens
A mechanic's lien, also called a construction lien, protects contractors, subcontractors, and suppliers who improve real property and are not paid. These liens are created by state statute, and the deadlines are strict. A supplier or subcontractor usually must send a preliminary notice to the owner within a set time after starting work, and a lien must be recorded within a deadline measured from the last day of work. Missing a deadline can wipe out the right to a lien. Because the rules are detailed and differ by state, anyone in the construction chain should track the notice and recording dates carefully.
Judgment Liens
When a court enters a money judgment, the winner can often create a lien by recording an abstract of judgment with the county. That lien attaches to the debtor's real property in that county, and it can appear on a title search when the property is sold or refinanced. A judgment can also be used to garnish wages or bank accounts, subject to state exemptions. A judgment lien usually lasts for a set number of years and can be renewed.
How to Find Out If Property Has a Lien
- Order a title search or title insurance commitment before buying real estate.
- Check the county recorder or registrar of deeds for recorded mortgages, judgments, and tax liens.
- Search the state UCC filing system for financing statements against a business.
- Review the certificate of title for a vehicle with the state motor vehicle agency.
- Request a tax lien search or check with the IRS and the state tax authority.
Removing a Lien
The most direct way to remove a lien is to pay the debt and obtain a written release or satisfaction, which the creditor records. Some disputes are resolved by proving the lien is invalid or expired, or by posting a bond to clear title while the dispute continues. In bankruptcy, certain liens can be avoided or stripped, but the rules depend on the type of lien, the property, and the chapter filed. Homestead exemptions protect a portion of a home's value from some creditors, and the protected amount varies by state. Because the consequences of an unresolved lien can include foreclosure or the inability to sell, a property owner who discovers a lien should act promptly.
Where the Rules Come From
Liens are governed by a mix of state statutes, state court decisions, federal tax law, and the Uniform Commercial Code. Article 9 of the UCC, adopted in some form in every state, governs security interests in personal property. State statutes govern mechanic's liens, judgment liens, and homestead exemptions. Federal law governs tax liens and certain other federal claims. The Legal Information Institute at law.cornell.edu provides overviews, but the controlling text is the statute in the relevant state.
