Conditional term 'when' signals temporal occurrence or a condition precedent governing the operation of legal clauses.

The word "when" serves as both a temporal marker and a conditional connector in legal texts, indicating time or circumstances under which a subsequent clause applies. Reference works note that it is often used interchangeably with "if" and can create a condition precedent in testamentary and transactional contexts, operating like "provided" or "as soon as" to determine whether rights or obligations arise upon occurrence or upon fulfillment of a prior condition.
