Client

Client: A person or organization that engages a lawyer for legal services. A lawyer owes a client duties of competence, communication, confidentiality and loyalty under the state's rules of professional conduct, and confidential lawyer-client communications made to obtain legal advice are generally protected by the attorney-client privilege.

Client — two people signing an agreement

What client means

In practice, you will see client in pleadings, motions, orders and court rules. The definition above explains the general meaning. Even so, the meaning can shift with context. Therefore, always read it alongside the rule or document where it appears.

Where client 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 client 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.
