Formerly, statutes governing wills used this phrase to specify children born to married parents, and to exclude those born out of wedlock. Now, the phrase means the same as issue and 'lineal descendant.'

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.

A legal principle, followed by most states, under which assets and earnings acquired during marriage are divided equitably (fairly) at divorce. In theory, equitable means equal, but in practice it often means that the higher wage earner gets two-thirds to the lower wage earner's one-third. If a spouse obtains a fault divorce, the 'guilty' spouse may receive less than his equitable share upon divorce.

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.

A tradition that required one spouse to prove that the other spouse was legally at fault, to obtain a divorce. The 'innocent' spouse was then granted the divorce from the 'guilty' spouse. Today, 35 states still allow a spouse to allege fault in obtaining a divorce. The traditional fault grounds for divorce are adultery, cruelty, desertion, confinement in prison, physical incapacity and incurable insanity. These grounds are also generally referred to as marital misconduct.
