An adult who has been given the legal right by a court to control and care for a minor or her property. Someone who looks after a child's property is called a 'guardian of the estate.' An adult who has legal authority to make personal decisions for the child, including responsibility for his physical, medical and educational needs, is called a 'guardian of the person.' Sometimes just one person will be named to take care of all these tasks. An individual appointed by a court to look after an incapacitated adult may also be known as a guardian, but is more frequently called a conservator.

An order that tells one person to stop harassing or harming another, issued after the aggrieved party appears before a judge. Once the TRO is issued, the court holds a second hearing where the other side can tell his story and the court can decide whether to make the TRO permanent by issuing an injunction.

Overdue alimony or child support payments. In recent years, state laws have made it difficult to impossible to get rid of arrearages; they can't be discharged in bankruptcy, and courts usually will not retroactively cancel them.

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.

The voluntary abandonment of one spouse by the other, without the abandoned spouse's consent. Commonly, desertion occurs when a spouse leaves the marital home for a specified length of time. Desertion is a grounds for divorce in states with fault divorce.

Latin for 'in chambers.' A legal proceeding is 'in camera' when a hearing is held before the judge in her private chambers or when the public is excluded from the courtroom. Proceedings are often held in camera to protect victims and witnesses from public exposure, especially if the victim or witness is a child. There is still, however, a record made of the proceeding, typically by a court stenographer. The judge may decide to seal this record if the material is extremely sensitive or likely to prejudice one side or the other.
