对预告登记性质的探讨涉及两个层面,一是预告登记本身的性质即形式意义上的性质,二是经预告登记后权利的性质即实质意义上的性质。经预告登记后产生的法律上之力与预告登记所担保的债权请求权的效力不同,它是一项形成权。 The discussion on the nature of advance notice registration involves two aspects. One is the nature of the registration itself, that is, the formal meaning, and the other is the nature of the right, that is, the substantive meaning after registration. The foregone conclusion of the legal force resulting from the registration is not the same as the validity of the right to claim secured by the advance notice of registration. It is a right of formation.
