Federal Tribunal Requires Clarity in
Bank Contracts and Substantiated Defence
in Banking Litigation
In a recent decision, the Swiss Federal Supreme Court set a high bar for banks when proving contract changes, applying standard clauses and defending against client claims in litigation.

Key takeaways from this case include:
  • Intent of the parties supersedes the content of the written contract.
  • Contract clarity is essential and banks must prove any contract change with clear evidence of mutual intent and explicit terms.
  • Standard ratification clauses must adapt to circumstances and strict deadlines may not apply especially if document transmission is delayed or is too voluminous, or if client objections persist.
  • High procedural burden on litigants — banks must contest client claims with detailed, evidence-based responses.
