overdue support
For purposes of this section, the term “overdue support” means the amount of a delinquency pursuant to an obligation determined under a court order, or an order of an administrative process established under State law, for support and maintenance of a minor child which is owed to or on behalf of such child, or for support and maintenance of the noncustodial parent’s spouse (or former spouse) with whom the child is living if and to the extent that spousal support (with respect to such spouse or former spouse) would be included for purposes of section 654(4) of this title . At the option of the State, overdue support may include amounts which otherwise meet the definition in the first sentence of this subsection but which are owed to or on behalf of a child who is not a minor child. The option to include support owed to children who are not minors shall apply independently to each procedure specified under this section.
