In most states, any person under 18 years of age. All minors must be under the care of a competent adult (parent or guardian) unless they are 'emancipated'--in the military, married or living independently with court permission. Property left to a minor must be handled by an adult until the minor becomes an adult under the laws of the state where he or she lives.

A person who initiates a lawsuit. A synonym for plaintiff, used almost universally in some states and in others for certain types of lawsuits, most commonly divorce and other family law cases.

A doctrine that grants the spouse least at fault a divorce when both spouses have shown grounds for divorce. It is a response to an old common-law rule that prevented a divorce when both spouses were at fault.

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.

In some states, a type of marriage in which couples can become legally married by living together for a long period of time, representing themselves as a married couple and intending to be married. Contrary to popular belief, the couple must intend to be married and act as though they are for a common law marriage to take effect -- merely living together for a long time won't do it.

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.'

Consensual sexual relations by a married person with someone other than his or her spouse. In many states, adultery is technically a crime, though people are rarely prosecuted for it. In states that have retained fault grounds for divorce, adultery is always sufficient grounds for a divorce. In addition, some states alter the distribution of property between divorcing spouses in cases of adultery, giving less to the 'cheating' spouse.

The right and obligation to make decisions about a child's upbringing, including schooling and medical care. Many states typically have both parents share legal custody of a child. Compare physical custody.

Differences between spouses that are considered sufficiently severe to make married life together more or less impossible. In a number of states, irreconcilable differences is the accepted ground for a no-fault divorce. As a practical matter, courts seldom, if ever, inquire into what the differences actually are, and routinely grant a divorce as long as the party seeking the divorce says the couple has irreconcilable differences. Compare incompatibility; irremediable breakdown.
