Surety

Surety: A person who promises to answer for another person's debt or obligation if that person does not perform. A co-signer on a loan and a bonding company that issues a bail or performance bond are common examples. Under UCC § 3-419, a person who signs a negotiable instrument to help another party get credit is an accommodation party with liability similar to a surety's.

How to research the term

To research surety, begin with the rule, statute or contract where the word is used. Each one can give it a slightly different meaning. Then compare that text with how courts in your area have applied it. Also check the local rules of your court, since they can add requirements. If your case is in state court, the state rules control. So start with our state procedures guide to find them. In the end, always confirm that the source you rely on is current.
