Which principle describes how a trade handles disputed language?

• A. Course of performance
• B. Course of dealing
• C. Usage of trade
• D. Legal precedent

Answer: (C)

Usage of trade governs how terms are interpreted based on the industry’s customary practices when contract language is disputed. It reflects the standard, widely observed ways a particular trade handles certain terms, so if language is ambiguous, those established practices fill in meaning and guide interpretation. This matters because it ties interpretation to what practitioners in that trade actually expect and do, rather than relying solely on the contract’s literal wording. By contrast, course of performance looks at how the contract was actually carried out, course of dealing looks at prior transactions between the same parties, and legal precedent relies on courts’ prior decisions rather than industry norms. So, when a term’s meaning is contested, the industry’s usage of trade provides the practical, norm-based interpretation.
