Consensual sexual relations by a married person with someone other than his or her spouse. In many states, adultery is technically a crime, though people are rarely prosecuted for it. In states that have retained fault grounds for divorce, adultery is always sufficient grounds for a divorce.

A court judgment that is not final until the judge decides other matters in the case or until enough time has passed to see if the interim decision is working. In the past, interlocutory decrees were most often used in divorces. The terms of the divorce were set out in an interlocutory decree, which would become final only after a waiting period. The purpose of the waiting period was to allow the couple time to reconcile. They rarely did, however, so most states no longer use interlocutory decrees of divorce.

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.

Differences between spouses that are considered sufficiently severe to make married life together more or less impossible. In a number of states, irreconcilable differences is the accepted ground for a no-fault divorce. As a practical matter, courts seldom, if ever, inquire into what the differences actually are, and routinely grant a divorce as long as the party seeking the divorce says the couple has irreconcilable differences. Compare incompatibility; irremediable breakdown.

The taking of a child from his or her parent with the intent to interfere with that parent's physical custody of the child. This is a crime in most states, even if the taker also has custody rights.
