The Consultant Termination Letter is a critical document used when ending a professional consulting engagement in Switzerland. It serves as the formal notification of termination and must comply with Swiss legal requirements, particularly the Swiss Code of Obligations governing mandate contracts. This document is typically used when either party wishes to end the consulting relationship, whether at the natural conclusion of the engagement or due to other circumstances. The letter should include essential elements such as reference to the original agreement, termination date, notice period, final deliverables, payment terms, and post-termination obligations. It's crucial for maintaining clear documentation of the termination process and ensuring all parties understand their rights and obligations during the transition period.
