lien

Old French lien meant 'bond, tie, restraint'—from Latin ligamen, 'a binding,' from ligare, 'to bind or tie.' The word described any kind of binding, physical or metaphorical. A lien was a rope, a chain, a connection. The legal meaning preserved the metaphor exactly: a lien binds property to a debt.

English law adopted lien in the 1530s. Under common law, a lien gave a creditor the right to hold a debtor's property until the debt was paid. An innkeeper had a lien on a guest's horse and luggage. A blacksmith had a lien on the horse he shod. The person in possession could not sell or release the property until they were paid.

American law expanded the concept dramatically. Mechanic's liens, first established in Maryland in 1791 at the urging of Thomas Jefferson, allowed builders and laborers to claim a lien on property they had improved. Jefferson wanted to encourage construction in the new capital city. The law said: if you build it and they don't pay, the building is your leverage.

Tax liens now represent one of the most powerful collection tools in modern government. The IRS files approximately 400,000 federal tax liens per year. A lien does not seize property—it encumbers it. Nothing is taken, but nothing can be sold free and clear. The binding holds.
