Collateral
Collateral: Property pledged to secure payment of a debt or performance of an obligation. If the debtor defaults, the secured party may be able to take or sell the collateral. Under UCC § 9-102(a)(12), collateral is the property subject to a security interest or agricultural lien.

What collateral means
In short, collateral is a term you will meet in court papers, rules and legal research. The definition above gives its usual meaning in American civil practice. However, the exact meaning can depend on the rule, statute or court decision that uses it. So it helps to read the term in context.
Where collateral comes up
For example, the term appears in these procedures:
- Writ of Garnishment (Fed. R. Civ. P. 64, 69(a); 15 U.S.C. § 1673; 42 U.S.C. § 407(a); state law): a court order directing a third party who owes money to, or holds property of, a debtor — such as an employer or bank — to pay or hold it for the creditor.
Read the source: Collateral estoppel.
How to research the term
First, read the term where it actually appears. A rule, statute or court decision may define it for its own purposes. Next, check whether your court has a local rule that uses collateral in a special way. Then look at recent decisions from courts in your jurisdiction. They show how judges apply the term today. Also, remember that state law can differ from federal law. For that reason, use our state procedures guide to find your state’s rules. Finally, confirm every source is current before you rely on it.
