动产添附之积极性债权效果

The Positive Claims Effects of Movable Property Accession

摘要: 动产添附发生后，在面临添附物所有权人破产风险时，作为普通债权人的原物所有权人处于不合理之不利地位。就如何救济作为债权人之原物所有权人，使其享有与添附物共有人同等保护之问题，学理上存在未决争议，现有观点未必完全符合价值判断、构造未必完全周延；实务中亦无统一法律适用，有必要明确动产添附之积极性债权效果。在返还范围上，原则上应采价金偿还请求权模式，于添附物所有权人不知添附时，例外采不当得利返还请求权模式，方符合添附制度之规范目的、风险与利益相一致原则；在优先地位上，依风险承担理论与一般债权人地位不变理论结合说，原物所有权人之债权应优先于普通债权受偿。

Abstract: After the accession of movable property, the original owner of the property, who is an ordinary creditor, is placed at an unreasonable disadvantage when facing the bankruptcy risk of the owner of the attached property. There is ongoing academic debate on how to provide relief to the original owner of the property as a creditor so that they receive protection equivalent to that of the co-owner of the attached property. Existing viewpoints may not fully align with value judgments, and their structures may not be entirely comprehensive. In practice, there is also no uniform legal application, making it necessary to clarify the positive claims effects of movable property accession. In terms of the scope of restitution, a restitution claim for the value of the property should generally be adopted, with an exception for cases where the owner of the attached property was unaware of the attachment, where a claim for unjust enrichment should be used instead. This approach aligns with the normative purpose of the attachment system and the principle of consistency between risks and benefits. Regarding priority status, based on the theory of risk-bearing and the theory of unchanged status of ordinary creditors, the claim of the original owner should have priority over the claims of ordinary creditors.
