A person that grants authority to represent to another person is liable towards a third party for an act performed between that other person and the third party within the scope of the authority to represent after the extinction of the authority to represent if that third party does not know the fact that the authority to represent has ceased to exist; provided, however, that this does not apply if the third party does not know the fact due to negligence.
他人に代理権を与えた者は、代理権の消滅後にその代理権の範囲内においてその他人が第三者との間でした行為について、代理権の消滅の事実を知らなかった第三者に対してその責任を負う。ただし、第三者が過失によってその事実を知らなかったときは、この限りでない。
If a person that grants authority to represent to another person is, pursuant to the provisions of the preceding paragraph, liable for an act performed between that other person and a third party within the scope of the authority to represent after the extinction of that authority to represent, and the other person performs in relation to the third party an act beyond the scope of the authority to represent, the person that grants authority to represent is liable for that act only if the third party has reasonable grounds for believing that the other person has authority to represent for the act.
他人に代理権を与えた者は、代理権の消滅後に、その代理権の範囲内においてその他人が第三者との間で行為をしたとすれば前項の規定によりその責任を負うべき場合において、その他人が第三者との間でその代理権の範囲外の行為をしたときは、第三者がその行為についてその他人の代理権があると信ずべき正当な理由があるときに限り、その行為についての責任を負う。
