Costs
Costs: Court-related expenses that a winning party may recover from the losing party, such as filing fees and transcript fees. In federal court, 28 U.S.C. § 1920 lists taxable costs. Attorney's fees are generally not included in costs.

What costs means
In short, costs 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 costs comes up
For example, the term appears in these procedures:
- Bill of Costs (Fed. R. Civ. P. 54(d)(1); 28 U.S.C. §§ 1920, 1924): the prevailing party's itemized request for the court costs it may recover from the losing party. Under Rule 54(d)(1), costs other than attorney's fees should be allowed to the prevailing party unless a federal statute, the rules or a court order provides otherwise. Costs against the United States may be imposed only to the extent allowed by law.

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 costs 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.

Why precise terms matter
Legal words often look like everyday words, but they can carry a precise meaning. Because of that, a small misreading can change how you understand a deadline, a duty or a right. Our glossary keeps each definition short and links it to the procedures where it matters.
