18(2)For the purposes of paragraph (1)(
i), if the fulfilment by a person of any obligation to support a person under subsection 14(2) would diminish the entitlement of any person who is or was lawfully married to that person, or of any child of that marriage, to support from that person, the Court, in making an order, shall, subject to section 20, give priority to the obligations owed by that person to the person to whom they are or were lawfully married and to any child of that marriage.
