A mistake by both spouses in a marriage that can serve as grounds for an annulment. For example, if one spouse went into the marriage wanting children while the other did not, they have a misunderstanding that will be judged serious enough for a court to terminate the marriage.

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.

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 reason for obtaining either a fault divorce or a no-fault divorce. It is rarely used, however, because of the difficulty of proving both the insanity of the spouse being divorced and that the insanity is incurable.

Most of the property accumulated by spouses during a marriage, called community property in some states. States differ as to exactly what is included in marital property; some states include all property and earnings dring the marriage, while others exclude gifts and inheritances.

A lawsuit to determine the identity of the father of a child born outside of marriage, and to provide for the support of the child once the identity of the father has been determined.

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.
