F58[(4A) Without prejudice to the generality of section 116 or 117, that part of an order to which this section applies which provides for the making of payments for the support of a dependent child of the civil partners shall stand discharged if he or she ceases to be a dependent child of the civil partners by reason of his or her attainment of the age of 18 years or 23 years, as the case may be, and shall be discharged by the court, on application to it under subsection (2), if it is satisfied that the child has for any reason ceased to be a dependent child of the civil partners.]

(7) The court shall not make an order under subsection (5) if it appears to the court that the order could prejudice the rights of a person who is not a F57[civil partner concerned or a dependent child of the civil partners concerned] and has acquired a right or interest in consequence of the order referred to in subsection (1)(e).

(8) This section applies, with any necessary modifications, to instruments executed pursuant to orders referred to in subsection (1) as it applies to those orders.
