Any powers conferred on a magistrates’ court by section 53 of the M1Magistrates’ Courts Act 1952 (which confers power to revoke, vary or revive orders for periodical payments) shall as respects a contribution order be exercisable, and exercisable only, by a magistrates’ court appointed for the commission area where the contributor is for the time being residing.

In proceedings for the variation of a contribution order, the local authority concerned shall specify the weekly amount which, having regard to section 46(2) of this Act, they propose should be the amount of the contribution payable under the order and the court shall not vary the contribution order so as to require the contributor to pay a contribution greater than that proposed by the local authority.
