Question 1

What is the Meaning of estoppel by convention?

Accepted Answer

Legal doctrine that prevents a party from denying a specific state of affairs when both parties have acted upon a shared assumption. Use of estoppel by convention arises when the participants in a transaction have conducted their dealings on a common basis, making it unjust for one to later assert the true legal position.

Question 2

What is the Shared Assumption of estoppel by convention?

Accepted Answer

Evidence must show that both sides relied on the same understanding of a fact or a legal point. In cases of estoppel by convention, the record of their conduct provides proof of this mutual belief. It is the act of proceeding as if the assumption were true that binds the parties.

Question 3

What is the Detrimental Reliance of estoppel by convention?

Accepted Answer

One party must have changed their position or incurred a cost based on the shared understanding. Without this element, estoppel by convention cannot be invoked to hold a party to the mistaken view.

Question 4

What is the Prohibitive Effect of estoppel by convention?

Accepted Answer

Application of the rule stops a party from retreating to the strict letter of the contract if doing so would cause unfairness. While estoppel by convention does not create new causes of action, it works to defend a claim by fixing the facts as the parties treated them. This maintains the stability of an arrangement that has been operational for a long period.
