What it is:
How it works/Example:
When someone takes out a sizeable loan, such as a home mortgage or an auto loan, the lender often requires an asset that can be held as collateral against the loan. Thus, the collateral has a lien placed upon it. In the event of non-payment on the part of the borrower, the lending institution can exercise the lien and sell the collateral asset to offset the unpaid loan. Once the loan is repaid in full, the collateral asset is returned to the borrower and the lien dissolved.
To illustrate, suppose someone takes out a $10,000 loan for a new car. As part of the loan's terms, the bank gets to hold the title to the car as a lien against the car until the loan is fully repaid. Should the borrower, at any point, default or refuse to repay the balance of the loan, the bank can use the title to the car to sell it in order to recover the money that was lent.
Why it Matters:
When purchasing a used car, for example, it's important to check for liens against the vehicle. If there is an outstanding debt on the car, the buyer runs the risk of having it repossessed by the lender.
