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.

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 lie by one spouse before marriage that provides grounds for an annulment. For example, if a spouse failed to mention that he was still married or was incapable of having children, he has misrepresented himself.

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.

An adult who has been given the legal right by a court to control and care for a minor or her property. Someone who looks after a child's property is called a 'guardian of the estate.' An adult who has legal authority to make personal decisions for the child, including responsibility for his physical, medical and educational needs, is called a 'guardian of the person.' Sometimes just one person will be named to take care of all these tasks. An individual appointed by a court to look after an incapacitated adult may also be known as a guardian, but is more frequently called a conservator.

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.
