The legal termination of marriage. All states require a spouse to identify a legal reason for requesting a divorce when that spouse files the divorce papers with the court. These reasons are referred to as grounds for a divorce.

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.

The situation that occurs in a marriage when one spouse refuses to live with the other and will not work toward reconciliation. In a number of states, irremediable breakdown is the accepted ground for a no-fault divorce. As a practical matter, courts seldom, if ever, inquire into whether the marriage has actually broken down, and routinely grant a divorce as long as the party seeking the divorce says the marriage has fallen apart. Compare incompatibility; irreconcilable differences.

A special kind of property ownership that's only for married couples. Both spouses have the right to enjoy the entire property, and when one spouse dies, the surviving spouse gets title to the property (called a right of survivorship). It is similar to joint tenancy, but it is available in only about half the states.

The act of inciting another person to do a particular thing. In a fault divorce, provocation may constitute a defense to the divorce, preventing it from going through. For example, if a wife suing for divorce claims that her husband abandoned her, the husband might defend the suit on the grounds that she provoked the abandonment by driving him out of the house.

An agreement made by a couple before marriage that controls certain aspects of their relationship, usually the management and ownership of property, and sometimes whether alimony will be paid if the couple later divorces. Courts usually honor premarital agreements unless one person shows that the agreement was likely to promote divorce, was written with the intention of divorcing or was entered into unfairly. A premarital agreement may also be known as a 'prenuptial agreement.'
