Long-term contract

A long-term contract, or continuing contractual relationship, is designed to operate over a period rather than through a single exchange. Swiss law treats many such contracts through specific contract types, such as lease or employment, and through general principles including good faith. Duration, renewal, price adjustment, termination, notice periods, and extraordinary termination for good cause are central issues. Because circumstances may change, parties often include mechanisms for adaptation, reporting, exclusivity, confidentiality, and post-contract duties. Mandatory rules can limit contractual freedom, especially in employment, tenancy, and consumer contexts.
