论合同无效或被撤销后返还请求权之性质——以合同法58条为视角

On the Nature of Contract Invalid or Revoked after Returned to the Claim——from the Perspective of Contract Law Article 58

合同在现在市场交易和财产流转中的地位不言而喻,而合同一旦被确认无效或被撤销之后,则会产生财产和利益的返还问题。我国合同法58条对合同无效后财产和利益返还问题规定得过于原则和笼统,其返还请求权之性质也是见仁见智,不仅给理论界带来了分歧,也给实务界带来诸多不便。因此,无论是从理论的角度还是从实务的角度,实有必要厘清合同无效或被撤销后财产和利益返还的请求权之性质。

The status of contracts in the market and property transfer is self-evident, and once a contract is confirmed as invalid or revoked, the return of the property and interests will be the problems. Chinese contract law article 58 of the returned property and interests of after the contract is invalid is too principle and general to act, which not only brings problems in theoretical fields, but the practices. Therefore, whether from the angle of the theory or from the perspective of practice, it is necessary to clarify the nature of contract invalid or revoked after returned to the claim.
