The inability of a spouse to engage in sexual intercourse with the other spouse. In some states, physical incapacity is a ground for an annulment or fault divorce, assuming the incapacity was not disclosed to the other spouse before the marriage.

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 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 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.

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.

Latin for 'friend of the court.' This term describes a person or organization that is not a party to a lawsuit as plaintiff or defendant but that has a strong interest in the case and wants to get its two cents in. For example, the ACLU often submits materials to support a person who claims a violation of civil rights even though that person is represented by a lawyer.

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.

In the trial court context, a legal proceeding (other than a full-scale trial) held before a judge. During a hearing, evidence and arguments are presented in an effort to resolve a disputed factual or legal issue. Hearings typically, but by no means always, occur prior to trial when a party asks the judge to decide a specific issue--often on an interim basis--such as whether a temporary restraining order or preliminary injunction should be issued, or temporary child custody or child support awarded. In the administrative or agency law context, a hearing is usually a proceeding before an administrative hearing officer or judge representing an agency that has the power to regulate a particular field or oversee a governmental benefit program. For example, the Federal Aviation Board (FAB) has the authority to hold hearings on airline safety, and a state Worker's Compensation Appeals Board has the power to rule on the appeals of people whose applications for benefits have been denied.
