Article 504Loss of Security by Obligee

第五百四条(債権者による担保の喪失等)

If there is a person that has legitimate interest in performing an obligation (referred to as a "person entitled to subrogation" in this paragraph below), and the obligee causes its security to be lost or diminished intentionally or negligently, the person entitled to subrogation is relieved from responsibility to the extent that that person can no longer seek the reimbursement due to the loss or diminution in the security available upon subrogation. If the person entitled to subrogation is a third-party collateral provider, the same applies to a third party that has acquired from the person entitled to subrogation the property that is the subject of security and to its specific successor.

弁済をするについて正当な利益を有する者(以下この項において「代位権者」という。)がある場合において、債権者が故意又は過失によってその担保を喪失し、又は減少させたときは、その代位権者は、代位をするに当たって担保の喪失又は減少によって償還を受けることができなくなる限度において、その責任を免れる。その代位権者が物上保証人である場合において、その代位権者から担保の目的となっている財産を譲り受けた第三者及びその特定承継人についても、同様とする。

The provisions of the preceding paragraph do not apply if the obligee is found to have reasonable grounds in light of common sense trading practices for causing the security to be lost or diminished.

前項の規定は、債権者が担保を喪失し、又は減少させたことについて取引上の社会通念に照らして合理的な理由があると認められるときは、適用しない。
