The principal secured by a revolving mortgage is fixed in the following cases:
次に掲げる場合には、根抵当権の担保すべき元本は、確定する。
if the revolving mortgagee has filed, with respect to the mortgaged immovables, a petition for auction or enforcement against earnings from secured immovable property or the attachment under the provisions of Article 304 as applied mutatis mutandis pursuant to Article 372;provided, however, that these provisions apply only if the commencement of either auction procedures or enforcement against earnings from secured immovable property, or a seizure has been effected;
if the revolving mortgagee has effected an attachment for disposition of delinquency against the mortgaged immovables;
根抵当権者が抵当不動産に対して滞納処分による差押えをしたとき。
if two weeks have passed from the time when the revolving mortgagee acquired knowledge of the commencement of auction procedures or seizure for disposition to collect arrears against the mortgaged immovables; or
根抵当権者が抵当不動産に対する競売手続の開始又は滞納処分による差押えがあったことを知った時から二週間を経過したとき。
if the obligor or mortgagor of the revolving mortgage has become subject to an order commencing bankruptcy proceeding.
債務者又は根抵当権設定者が破産手続開始の決定を受けたとき。
If the commencement of auction procedures, the seizure under item (iii) of the preceding paragraph or the order commencing bankruptcy proceeding under item (iv) of that paragraph ceases to be effective, it is deemed that the principal secured was not fixed; provided, however, that this does not apply if a person has acquired that revolving mortgage or a right for which the revolving mortgage is the subject on the assumption that the principal was fixed.
