The Amended Contract is a crucial legal instrument used when parties need to modify an existing agreement while maintaining its core structure under Swiss law. This document type is particularly relevant when circumstances require adjustments to original contract terms, such as changes in scope, pricing, duration, or other material terms. It must comply with the Swiss Code of Obligations (OR) requirements for contract modifications, including form requirements and the principle that amendments typically need to follow the same formal requirements as the original contract. The document is commonly used in various business contexts, from simple bilateral agreements to complex commercial arrangements, and requires careful attention to both the amendment provisions and their interaction with the original contract terms. It's essential to ensure that the amendments are precisely drafted to avoid any ambiguity regarding which original terms remain in force and which are being modified.

1. Parties: Identification of all parties to the amended contract, including their full legal names, addresses, and registration details

2. Background: Reference to the original contract (including date and parties), reason for amendment, and confirmation that parties wish to amend the original contract

3. Definitions: Key terms used in the amendment, including reference to definitions in the original contract that remain applicable

4. Amendment Authority: Reference to the clause in the original contract permitting amendments and confirmation of compliance with amendment requirements

5. Amendments: Detailed specification of each amendment, clearly identifying the original clauses being modified and their new text

6. Effective Date: Specification of when the amendments take effect

7. Continued Validity: Confirmation that all unmodified provisions of the original contract remain in full force and effect

8. Entire Agreement: Confirmation that the original contract and this amendment together constitute the entire agreement

9. Governing Law: Confirmation of Swiss law as governing law (typically maintaining the same jurisdiction as the original contract)

10. Execution: Signature blocks for all parties
