17.—(1) The Court that made an attachment of earnings order may, if it thinks fit, on the application of the maintenance creditor, the maintenance debtor or the District Court clerk on whose application the order was made, make an order discharging or varying that order.

(2) Where an order varying an attachment of earnings order is made under this section, the employer shall, if it has been served upon him, comply with it, but he shall be under no liability for non-compliance before ten days have elapsed since the service.

(3) Where an employer affected by an attachment of earnings order ceases to have the maintenance debtor in his employment, the order shall, in so far as that employer is concerned, lapse (except as respects deductions from earnings paid after the cesser by that employer and payment to the person in whose favour the order was made of deductions from earnings made at any time by that employer).

(4) The lapse of an order under subsection (3) of this section shall not prevent its remaining in force for other purposes.
