What are joint promisors responsible for in a contract?

In a contract where there are joint promisors, they are collectively responsible for fulfilling the promise made within that agreement. This means that each promisor is bound to ensure that the obligations of the contract are met as a unit, rather than independently. This principle reflects the notion of joint liability—if the promise is not fulfilled by one party, the other parties may be held accountable for the entire obligation.

When joint promisors are involved, it creates a legal environment where performance is expected to be simultaneous and coordinated, emphasizing the collective nature of their responsibilities. This structure allows for remedies to be sought against any of the joint promisors if the promise is breached, regardless of individual participation in the failure to perform.

The other options do not accurately capture the nature of joint promisor obligations in a contract. For instance, individual performance without collaboration contradicts the essence of joint liability. Taking turns to perform tasks is misleading since the obligations are not inherently temporal or sequential. Lastly, requiring a separate agreement for each party undermines the principle of joint responsibility, as it indicates that each party operates independently, which is not the case when parties are joint promisors.
