Victor Adoption Lawyer, New York, page 2

Papers filed with a court clerk by the plaintiff to initiate a lawsuit by setting out facts and legal claims (usually called causes of action). In some states and in some types of legal actions, such as divorce, complaints are called petitions and the person filing is called the petitioner. To complete the initial stage of a lawsuit, the plaintiff's complaint must be served on the defendant, who then has the opportunity to respond by filing an answer. In practice, few lawyers prepare complaints from scratch. Instead they use -- and sometimes modify -- pre-drafted complaints widely available in form books.

A document that authorizes a couple to get married, usually available from the county clerk's office in the state where the marriage will take place. Couples pay a small fee for a marriage license, and must often wait a few days before it is issued. In addition, a few states require a short waiting period--usually not more than a day--between the time the license is issued and the time the marriage may take place. And some states still require blood tests for couples before they will issue a marriage license, though most no longer do.

A document used to submit a legal contention or argument to a court. A brief typically sets out the facts of the case and a party's argument as to why she should prevail. These arguments must be supported by legal authority and precedent, such as statutes, regulations and previous court decisions. Although it is usually possible to submit a brief to a trial court (called a trial brief), briefs are most commonly used as a central part of the appeal process (an appellate brief). But don't be fooled by the name -- briefs are usually anything but brief, as pointed out by writer Franz Kafka, who defined a lawyer as 'a person who writes a 10,000 word decision and calls it a brief.'

Latin for 'friend of the court.' This term describes a person or organization that is not a party to a lawsuit as plaintiff or defendant but that has a strong interest in the case and wants to get its two cents in. For example, the ACLU often submits materials to support a person who claims a violation of civil rights even though that person is represented by a lawyer.

A formal request for a green card or a specific nonimmigrant (temporary) visa. In many cases, the petition must be filed by someone sponsoring the immigrant, such as a family member or employer. After the petition is approved, the immigrant may submit the actual visa or green card application.
