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.

A child placed by a government agency or a court in the care of someone other than his or her natural parents. Foster children may be removed from their family home because of parental abuse or neglect. Occasionally, parents voluntarily place their children in foster care. See foster care.

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.

An arrangement by which parents who do not live together share the upbringing of a child. Joint custody can be joint legal custody (in which both parents have a say in decisions affecting the child) joint physical custody (in which the child spends a significant amount of time with both parents) or, very rarely, both.

A court decision that is intended to prevent harm--often irreparable harm--as distinguished from most court decisions, which are designed to provide a remedy for harm that has already occurred. Injunctions are orders that one side refrain from or stop certain actions, such as an order that an abusive spouse stay away from the other spouse or that a logging company not cut down first-growth trees. Injunctions can be temporary, pending a consideration of the issue later at trial (these are called interlocutory decrees or preliminary injunctions). Judges can also issue permanent injunctions at the end of trials, in which a party may be permanently prohibited from engaging in some conduct--for example, infringing a copyright or trademark or making use of illegally obtained trade secrets. Although most injunctions order a party not to do something, occasionally a court will issue a 'mandatory injunction' to order a party to carry out a positive act--for example, return stolen computer code.

A mistake by both spouses in a marriage that can serve as grounds for an annulment. For example, if one spouse went into the marriage wanting children while the other did not, they have a misunderstanding that will be judged serious enough for a court to terminate the marriage.

A document that provides proof of a marriage, typically issued to the newlyweds a few weeks after they file for the certificate in a county office. Most states require both spouses, the person who officiated the marriage and one or two witnesses to sign the marriage certificate; often this is done just after the ceremony.

A legal reason for obtaining either a fault divorce or a no-fault divorce. It is rarely used, however, because of the difficulty of proving both the insanity of the spouse being divorced and that the insanity is incurable.
