The Car Booking Cancellation Letter is a crucial document used in the Swiss market when a customer needs to formally terminate a vehicle rental reservation. This document is essential for maintaining clear communication and legal compliance under Swiss law, particularly the Swiss Code of Obligations (OR). It should be used whenever a pre-arranged vehicle booking needs to be cancelled, whether for personal or business reasons. The letter typically includes crucial information such as booking references, rental dates, vehicle details, and cancellation reasoning. It serves multiple purposes: documenting the cancellation request, establishing the cancellation date for legal purposes, and initiating any applicable refund processes. The document must be drafted in accordance with Swiss legal requirements, which may vary depending on the canton and whether the communication is in German, French, or Italian business regions of Switzerland.
