Attachment of pension or income

(1) When a maintenance order has been made, the magistrate of the district in which the order has been made may, after giving the father an opportunity of being heard if such father has without reasonable cause made a default under the order, at any time in any case where there is any salary, pension or income payable to the father and capable of being attached, order that such an amount each week as is specified in the maintenance order, or any part of such amount, as the case may be, be attached and paid to the collecting officer. (2) Such order shall be sufficient authority to the person by whom such salary, pension or income is payable to make the payment so ordered, and the receipt of the collecting officer shall be a good discharge to such person to the extent of the amount so paid.
