The formal, legal adoption of a child by a stepparent who is living with a legal parent. Most states have special provisions making stepparent adoptions relatively easy if the child's noncustodial parent gives consent, is dead or missing, or has abandoned the child.

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.'

An order from a judge that directs a party to come to court and convince the judge why she shouldn't grant an action proposed by the other side or by the judge on her own (sua sponte). For example, in a divorce, at the request of one parent a judge might issue an order directing the other parent to appear in court on a particular date and time to show cause why the first parent should not be given sole physical custody of the children. Although it would seem that the person receiving an order to show cause is at a procedural disadvantage--she, after all, is the one who is told to come up with a convincing reason why the judge shouldn't order something--both sides normally have an equal chance to convince the judge to rule in their favor.

Adulthood in the eyes of the law. After reaching the age of majority, a person is permitted to vote, make a valid will, enter into binding contracts, enlist in the armed forces and purchase alcohol. Also, parents may stop making child support payments when a child reaches the age of majority. In most states the age of majority is 18, but this varies depending on the activity. For example, in some states people are allowed to vote when they reach the age of eighteen, but can't purchase alcohol until they're 21.

The biological father of a child born to an unmarried couple who has been established as the father either by his admission or by an agreement between him and the child's mother. An acknowledged father must pay child support.

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 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.
