On Legal Application Issues pertaining to Obligation of Unjust Enrichment in International Civil and Commercial Transactions

由于世界各国关于不当得利的法律制度不尽相同,国际民商事交往中不当得利的法律冲突问题日益突出。为保证支配不当得利之债的准据法与当事人的意愿相一致或有最密切的联系,并最大限度地减小因识别或定性不同而带来的难题,不当得利准据法应依序设计为：不当得利起因于合同时,适用该合同的准据法;起因于其他法律关系时,适用调整该法律关系的法律;起因于不动产交易时,适用不动产所在地法;在其他情况下产生,则其准据法为利益发生地所在国的法律。

The legal systems of unjust enrichment differ among different countries, resulting in severe conflicts of applicable law in international civil and commercial transactions. To ensure that the applicable law on unjust enrichment is in consistent with or in the closest relation to the agreement of parties concerned, and to minimize obstacles resulted from different identity and specification to the greatest extent, the design of applicable law on unjust enrichment is suggested as follows： the applicable law on contract applies when unjust enrichment resulted from contract; the applicable law on other legal relations apply when aroused thereby; the applicable law where the real property is located shall apply when aroused by real property transaction; the applicabie law where interest incurs shall apply in other circumstances.
