Any act of inflicting unnecessary emotional or physical pain. Cruelty or mental cruelty is the most frequently used fault ground for divorce because as a practical matter, courts will accept minor wrongs or disagreements as sufficient evidence of cruelty to justify the divorce.

One person's approval of another's activities, constituting a defense to a fault divorce. For example, if a wife did not object to her husband's adultery and later tries to use it as grounds for a divorce, he could argue that she had condoned his behavior and could perhaps prevent her from divorcing him on these grounds.

A divorce automatically granted by a court when the spouse who is served with a summons and complaint for divorce fails to file a formal response with the court. Many divorces proceed this way when the spouses have worked everything out and there's no reason for both to go to court -- and pay the court costs.

A lawsuit to determine the identity of the father of a child born outside of marriage, and to provide for the support of the child once the identity of the father has been determined.

An investigation of prospective adoptive parents to make sure they are fit to raise a child, required by all states. Common areas of inquiry include financial stability, marital stability, lifestyles and other social factors, physical and mental health and criminal history.

A term that most often refers to a lawsuit -- for example, 'I filed my small claims case.' 'Case' also refers to a written decision by a judge -- or for an appellate case, a panel of judges. For example, the U.S. Supreme Court's decision legalizing abortion is commonly referred to as the Roe v. Wade case. Finally, the term also describes the evidence a party submits in support of her position -- for example, 'I have made my case' or ''My case-in-chief' has been completed.'

A legal principle, followed by most states, under which assets and earnings acquired during marriage are divided equitably (fairly) at divorce. In theory, equitable means equal, but in practice it often means that the higher wage earner gets two-thirds to the lower wage earner's one-third. If a spouse obtains a fault divorce, the 'guilty' spouse may receive less than his equitable share upon divorce.

A situation in which the partners in a married couple live apart. Spouses are said to be living apart if they no longer reside in the same dwelling, even though they may continue their relationship. A legal separation results when the parties separate and a court rules on the division of property, such as alimony or child support -- but does not grant a divorce.
