61.—(1) Where it appears to the Office that a debtor has a beneficial interest in any debenture of or mortgage by any local authority or other public undertaking in Northern Ireland or in any debenture of any public or private company incorporated in Northern Ireland, the Office may make a debenture order requiring the payment to the creditor or the Office, as the order may direct, of the principal or interest or both when the principal or so often as the interest becomes due on the debenture or mortgage, in full or part satisfaction of the amount recoverable on foot of the judgment.
(2) A debenture order shall, from the time of service of a copy thereof on a local authority, public undertaking or company specified in the order, operate so as to restrain that local authority, public undertaking or company, as the case may be, from dealing with any such debenture or mortgage save as provided by this Article.
