Summary
Contract law in Switzerland regulates agreements between private parties and establishes the legal framework governing contractual rights and obligations. It determines how contracts are formed, interpreted, performed, and enforced when disputes arise.
Contract law applies across both personal and commercial relationships, including everyday agreements and business transactions.
Swiss contract law is primarily governed by the Swiss Code of Obligations, which sets out the rules governing contractual relationships in both commercial and private contexts.
What Contract Law Means Under Swiss Law
Contract law in Switzerland regulates legally binding agreements between private parties.
A contract is generally formed where:
- parties reach mutual agreement
- there is an intention to create legal obligations
- the terms of the agreement can be determined
Questions may arise where parties disagree about whether a binding agreement exists or what terms were agreed.
Swiss law recognises both written and oral agreements, provided the essential elements of a contract are present.

Contract law in Switzerland operates through a structured system of obligations and remedies.
In practice, this involves:
