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.

A legal relationship created by a court between a guardian and his ward--either a minor child or an incapacitated adult. The guardian has a legal right and duty to care for the ward.

A term used by the Uniform Transfers to Minors Act for the person named to manage property left to a child under the terms of that Act.

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.

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.
