Glen Aubrey Divorce & Family Law Lawyer, New York

A term used instead of defendant or appellee in some states -- especially for divorce and other family law cases -- to identify the party who is sued and must respond to the petitioner's complaint.

A person, usually a relative, who appears in court on behalf of a minor or incompetent plaintiff, but who is not a party to the lawsuit. For example, children are often represented in court by their parents as 'next friends.'

A court procedure by which an adult becomes the legal parent of someone who is not his or her biological child. Adoption creates a parent-child relationship recognized for all legal purposes -- including child support obligations, inheritance rights and custody.

In most states with fault divorce, grounds for a spouse not in prison to obtain a fault divorce if the other spouse has been imprisoned for a certain number of years.

A court procedure that dissolves a marriage and treats it as if it never happened. Annulments are rare since the advent of no-fault divorce but may be obtained in most states for one of the following reasons: misrepresentation, concealment (for example, of an addiction or criminal record), misunderstanding and refusal to consummate the marriage.

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.

A person, not necessarily a lawyer, who is appointed by a court to represent and protect the interests of a child or an incapacitated adult during a lawsuit. For example, a guardian ad litem (GAL) may be appointed to represent the interests of a child whose parents are locked in a contentious battle for custody, or to protect a child's interests in a lawsuit where there are allegations of child abuse. The GAL may conduct interviews and investigations, make reports to the court and participate in court hearings or mediation sessions. Sometimes called court-appointed special advocates (CASAs).

A situation in which a famous trademark or service mark is used in a context in which the mark's reputation for quality is tarnished or its distinction is blurred. In this case, trademark infringement exists even though there is no likelihood of customer confusion, which is usually required in cases of trademark infringement. For example, the use of the word Candyland for a pornographic site on the Internet was ruled to dilute the reputation of the Candyland mark for the well-known children's game, even though the traditional basis for trademark infringement (probable customer confusion) wasn't an issue.

A term generally meaning all your children and their children down through the generations, including grandchildren, great-grandchildren, and so on. Also called 'lineal descendants.'
