Lien
A legal claim on a property or asset as security for a debt, preventing the owner from transferring clear title until the debt is paid.
Legal Definition
A lien is a legal right or claim that a creditor holds over a debtor's property as security for a debt or obligation. If the debtor fails to repay the debt, the lienholder can force the sale of the property to recover what's owed. Liens can be voluntary — like a mortgage, which you agree to when borrowing to buy a home — or involuntary, such as a tax lien placed by the government for unpaid taxes or a mechanic's lien filed by a contractor who wasn't paid. A property with an outstanding lien cannot be sold or refinanced until the lien is satisfied or released.
In Plain English
A lien is a legal sticky note on your property that says 'this asset is promised as collateral for a debt.' The most common lien most people encounter is a mortgage — the bank lends you money to buy a house and places a lien on the title. You can live in and use the house freely, but you can't sell it without satisfying the mortgage and getting the lien released. If you stop paying, the lienholder can foreclose. Other liens can be placed without your agreement: if you don't pay your contractor, they can file a mechanic's lien. Unpaid federal or state taxes result in a tax lien. An IRS lien attaches to everything you own and severely limits your financial options until resolved.
Real-World Example
David hires a roofing company for $15,000 and pays only $10,000, leaving $5,000 unpaid. The roofing company files a mechanic's lien on his home. Six months later, David tries to sell. The title company discovers the lien — the sale cannot close with a lien outstanding. David must either pay the roofing company the $5,000 (releasing the lien) or dispute it in court before the property can be transferred. The lien effectively blocks the sale until the debt is resolved.
