If there are multiple mortgages on the same mortgaged property, a mortgagee may adjust its proportional share of preferential right to satisfaction by the following means, provided that the interests of the other mortgagees are not thereby affected:1. Assigning the priority ranking of its mortgage in favor of a specified mortgagee.2. Waiving the priority ranking of its mortgage in favor of a specified mortgagee of lesser priority.3. Waiving the priority ranking of its mortgage in favor of all mortgagees of lesser priority.No assignment or waiver of the priority ranking of a mortgage pursuant to the preceding paragraph will take effect without registration. Prior to such registration, the mortgagee shall notify the debtor, the mortgagor, and any joint mortgagors.A mortgagee who benefits from an adjustment in priority rankings under paragraph 1 also may enforce the mortgage with the higher pre-adjustment ranking.When an adjustment is made to the proportional share of preferential right to satisfaction, if the claim secured by the higher ranking mortgage is also secured by real property of a third party, the mortgage to which the third party's real property is subject will be extinguished to the extent of any increase in encumbrance on the property that results from the adjustment, unless the third party has otherwise given its consent.
中文原文 民法第870-1條
同一抵押物有多數抵押權者，抵押權人得以下列方法調整其可優先受償之分配額。
但他抵押權人之利益不受影響：
一、為特定抵押權人之利益，讓與其抵押權之次序。
二、為特定後次序抵押權人之利益，拋棄其抵押權之次序。
三、為全體後次序抵押權人之利益，拋棄其抵押權之次序。
前項抵押權次序之讓與或拋棄，非經登記，不生效力。
並應於登記前，通知債務人、抵押人及共同抵押人。
因第一項調整而受利益之抵押權人，亦得實行調整前次序在先之抵押權。
調整優先受償分配額時，其次序在先之抵押權所擔保之債權，如有第三人之不動產為同一債權之擔保者，在因調整後增加負擔之限度內，以該不動產為標的物之抵押權消滅。
但經該第三人同意者，不在此限。
