Final answer:
A condition in contract law is an event that must occur before a party becomes obligated under a contract.
Step-by-step explanation:
A condition in contract law is an event that must occur before a party becomes obligated under a contract. This means that the condition is a prerequisite for the parties to be bound by the terms of the contract.
For example, if a contract states that one party will deliver goods to another party provided that the payment is made in advance, the condition in this case is the payment being made in advance. The party delivering the goods is not obligated to do so unless the condition is met.
