論臺灣不動產物權變動之登記效力

A Legal Analysis on the effect of Mutation Registration in Taiwanese Real Estate Rights

本文首先從設權登記作為依法律行為而發生之不動產物權變動的生效要件，以及宣示登記作為非因法律行為而發生之不動產物權變動的處分要件這兩大視角，說明臺灣不動產物權變動之登記效力。其次，本文引介行使不動產所有物返還請求權之消滅時效，並討論最高法院關於行使不動產所有權暨其限制之重要案例。其後，本文闡述權利外觀原則在不動產物權變動場域之兩大實務紛爭案型──無權處分與公信原則、以及表見代理與信賴保護。本文倡議第三人善意取得不動產所有權者，應以其係透過相當對價取得者為限。最後，本文指出我國民法物權編在採取登記生效主義之規範下，晚近逐漸將登記公示之對象，從物權歸屬內容擴增到物權當事人間之若干債權約定事項，毋寧強化以登記之公示方法作為賦予和不動產有關之債權約定具有物權效力的正當化基礎，具有臺灣不動產登記公示原則之特色。

The purpose of this article, which is divided into four parts, is to analyze Taiwanese mutation of real estate rights in rem. Following an introduction respectively relative to right registration through the juridical act and to declaration registration through non juridical act, Part II explores the exercise of ownership and its extinctive prescription besides abuse of rights. Then, Part III examines the concretization of the principle of apparent right, unauthorized disposition in one hand and apparent agency in the other hand. It advocates that a third party of good faith can obtain the ownership of real property only if he acquires that at equivalent consideration. Finally, Part IV concludes by observing the characteristic of Taiwanese real estate recordation in registration publicity.
