(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) The employer on whom an order varying an attachment of earnings order is served shall comply with it but is not liable for non-compliance before 10 days have elapsed since the service.

(3) If an employer affected by an attachment of earnings order ceases to be the maintenance debtor’s employer, the order lapses insofar as that employer is concerned, except as respects deductions from earnings paid by the employer after the cesser and payment to the maintenance creditor of deductions from earnings made at any time by that employer.

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