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.

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 document used to submit a legal contention or argument to a court. A brief typically sets out the facts of the case and a party's argument as to why she should prevail. These arguments must be supported by legal authority and precedent, such as statutes, regulations and previous court decisions. Although it is usually possible to submit a brief to a trial court (called a trial brief), briefs are most commonly used as a central part of the appeal process (an appellate brief). But don't be fooled by the name -- briefs are usually anything but brief, as pointed out by writer Franz Kafka, who defined a lawyer as 'a person who writes a 10,000 word decision and calls it a brief.'

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.'

Court-ordered care provided to children who are unable to live in their own homes, usually because their parents have abused or neglected them. Foster parents have a legal responsibility to care for their foster children, but do not have all the rights of a biological parent--for example, they may have limited rights to discipline the children, to raise them according to a certain religion or to authorize non-emergency medical procedures for them. The foster parents do not become the child's legal parents unless the biological parents' rights are terminated by a court and the foster parents adopt the child. This is not typically encouraged, as the goal of foster care is to provide temporary support for the children until they can be returned to their parents. See also foster child.

Papers filed with a court clerk by the plaintiff to initiate a lawsuit by setting out facts and legal claims (usually called causes of action). In some states and in some types of legal actions, such as divorce, complaints are called petitions and the person filing is called the petitioner. To complete the initial stage of a lawsuit, the plaintiff's complaint must be served on the defendant, who then has the opportunity to respond by filing an answer. In practice, few lawyers prepare complaints from scratch. Instead they use -- and sometimes modify -- pre-drafted complaints widely available in form books.

The formal, legal adoption of a child by a stepparent who is living with a legal parent. Most states have special provisions making stepparent adoptions relatively easy if the child's noncustodial parent gives consent, is dead or missing, or has abandoned the child.

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.

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. In addition, some states alter the distribution of property between divorcing spouses in cases of adultery, giving less to the 'cheating' spouse.
