Guilty
Guilty: Responsible for a crime. A defendant becomes guilty in the legal sense by pleading guilty or by being found guilty at trial beyond a reasonable doubt. In federal court, a judge must make sure a guilty plea is voluntary and has a factual basis before accepting it (Fed. R. Crim. P. 11(b)).

What guilty means
Put simply, guilty is part of the working vocabulary of a civil case. The short definition above covers the usual meaning. Still, a specific rule, statute or contract can give it a narrower meaning. For that reason, check how it is used in your own documents.
Where guilty comes up
The term is used across many kinds of cases. For example, you may see it in pleadings, motions and court orders. To see it in context, browse the motions and procedures library or the Learn the Law topics.

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 guilty 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.
