Lancy Divorce & Family Law Lawyer, Switzerland

A custody arrangement in the case of multiple children, awarding sole custody of one child to one parent and sole custody of another child to the other parent. This arrangement is generally disfavored by judges because they are reluctant to split up siblings.

A conflict in personalities that makes married life together impossible. In a number of states, incompatibility is the accepted reason for a no-fault divorce. Compare irreconcilable differences; irremediable breakdown.

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.

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 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.

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.'

A court procedure that dissolves a marriage and treats it as if it never happened. Annulments are rare since the advent of no-fault divorce but may be obtained in most states for one of the following reasons: misrepresentation, concealment (for example, of an addiction or criminal record), misunderstanding and refusal to consummate the marriage.

In some states, a type of marriage in which couples can become legally married by living together for a long period of time, representing themselves as a married couple and intending to be married. Contrary to popular belief, the couple must intend to be married and act as though they are for a common law marriage to take effect -- merely living together for a long time won't do it.
