Federal Act
on the Amendment of the Swiss Civil Code
(Part Five: The Code of Obligations)

¹ Where the surety pays the prin­cip­al ob­lig­a­tion in full or in part, he must no­ti­fy the prin­cip­al debt­or.

² If he fails to do so and the prin­cip­al debt­or pays it again be­cause he was not and could not be ex­pec­ted to be aware of the surety’s pay­ment, the surety for­feits his right of re­course against the prin­cip­al debt­or.

³ This does not af­fect any claim against the cred­it­or for un­just en­rich­ment.
