A claim (www.practicallaw.com/4-382-3333) held by a creditor who has a perfected lien (www.practicallaw.com/7-382-3685) or a right of set-off (www.practicallaw.com/6-382-3817) against the debtor's property. A claim is secured to the extent of the creditor's interest in the debtor's property or to the extent of the amount subject to set-off. In a bankruptcy case, secured claims are satisfied before any other claims out of the proceeds of the collateral (www.practicallaw.com/3-382-3343) which secure them.
