Final answer:
The element that is not traditionally a part of the doctrine of promissory estoppel is valuable consideration on both sides of the bargain.
Step-by-step explanation:
The correct answer is B, Valuable consideration on both sides of the bargain.
Promissory estoppel is a legal doctrine that allows a party to enforce a promise even if there is no formal contract. To establish a claim of promissory estoppel, the following elements must be present:
- A promise: There must be a clear and definite promise made by one party to another.
- Reasonable reliance: The promisee must reasonably rely on the promise and take action or forbear from taking action based on that reliance.
- Detrimental reliance: The promisee must suffer a detriment or harm as a result of relying on the promise.
Valuable consideration is not required for promissory estoppel, as it is for the formation of a contract. In promissory estoppel, the focus is on the promise and the reliance, rather than an exchange of consideration.
