Contra Proferentem CASES

In English law, the contra proferentem rule is a principle of contractual interpretation stating that any ambiguity in contract terms is interpreted against the party who drafted or proposed the wording.

Definition and Principles

Contra proferentem (literally “against the offeror”) applies particularly to exclusion clauses or limitation clauses that seek to restrict liability. Where terms are unclear, the interpretation least favourable to the drafter is adopted.

Application

  • Primarily applied to ambiguities in standard-form contracts or exclusion clauses.
  • Encourages clarity and transparency from the drafting party.

Practical Importance

Businesses and individuals should draft clear, precise terms to avoid unintended interpretations and potential liability. Ambiguous clauses risk being rendered ineffective or narrowly interpreted.

Example Contexts

  • Insurance contracts.
  • Consumer agreements with complex exclusions.
  • Standard business terms and conditions.
