An obligor may duly assert against the assignee a set-off based on a claim against the assignor that the obligor acquired before the time when the requirements for perfection are satisfied.
債務者は、対抗要件具備時より前に取得した譲渡人に対する債権による相殺をもって譲受人に対抗することができる。
The preceding paragraph also applies to a claim against the assignor that the obligor acquires after the time when the requirements for perfection are satisfied if the claim is any of the following; provided, however, that this does not apply if the obligor acquires a claim of another person after the time when the requirements for perfection are satisfied:
a claim that has arisen from a cause that existed before the time when the requirements for perfection are satisfied; or
対抗要件具備時より前の原因に基づいて生じた債権
beyond what is stated in the preceding item, a claim that has arisen from a contract under which the claim acquired by the assignee has arisen.
前号に掲げるもののほか、譲受人の取得した債権の発生原因である契約に基づいて生じた債権
To apply the provisions of the preceding two paragraphs in the case referred to in Article 466, paragraph (4), the phrase "at the time when the requirements for perfection are satisfied" in these provisions is deemed to be replaced with "at the time when a reasonable period of time referred to in Article 466, paragraph (4) has passed"; and to apply these provisions in the case referred to in Article 466-3, the phrase "at the time when the requirements for perfection are satisfied" in these provisions is deemed to be replaced with "at the time when the obligor receives a request from the assignee referred to in Article 466-3 to make a deposit with an official depository pursuant to the provisions of that Article".
