legal ground

Article 406 of the Civil Code

During the mortgage period, the mortgagor may transfer the mortgaged property. Unless otherwise agreed by the parties, such agreement shall prevail. If the mortgaged property is transferred, the mortgage right will not be affected. Where the mortgagor transfers the mortgaged property, it shall promptly notify the mortgagee. If the mortgagee can prove that the transfer of the mortgaged property may damage the mortgage right, he may require the mortgagor to pay off the debt or deposit the proceeds of the transfer in advance with the mortgagee. The part of the transfer price exceeding the amount of creditor's rights belongs to the mortgagor, and the insufficient part is paid off by the debtor.

Article 4 13

After the mortgaged property is discounted, auctioned or sold, the part of the price exceeding the amount of creditor's rights belongs to the mortgagor, and the insufficient part is paid off by the debtor.
