Laura Divorce & Family Law Lawyer, Illinois

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 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.

The laws dividing cities into different areas according to use, from single-family residences to industrial plants. Zoning ordinances control the size, location, and use of buildings within these different areas.

Secret cooperation between two people in order to fool another. Collusion was often practiced by couples before no-fault divorce in order to make up a grounds for divorce (such as adultery). By fabricating a permitted reason for divorce, colluding couples hoped to trick a judge into granting their freedom from the marriage. But a spouse accused of wrongdoing who later changed his or her mind about the divorce could expose the collusion to prevent the divorce from going through.

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.

Latin for 'in chambers.' A legal proceeding is 'in camera' when a hearing is held before the judge in her private chambers or when the public is excluded from the courtroom. Proceedings are often held in camera to protect victims and witnesses from public exposure, especially if the victim or witness is a child. There is still, however, a record made of the proceeding, typically by a court stenographer. The judge may decide to seal this record if the material is extremely sensitive or likely to prejudice one side or the other.

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.

The right and obligation to make decisions about a child's upbringing, including schooling and medical care. Many states typically have both parents share legal custody of a child. Compare physical custody.
