Children Act 1989

8 (1) This paragraph applies where a residence order is made with respect to a child at a time when there is in force an order (“the financial relief order”) made under any enactment other than this Act and requiring a person to contribute to the child’s maintenance.

(2) Where this paragraph applies, the court may, on the application of—

(a) any person required by the financial relief order to contribute to the child’s maintenance; or

(b) any person in whose favour a residence order with respect to the child is in force,

make an order revoking the financial relief order, or varying it by altering the amount of any sum payable under that order or by substituting the applicant for the person to whom any such sum is otherwise payable under that order.
