Equitable Estoppel is a legal principle that prevents a party from arguing something contrary to a claim they previously made if another party relied on that claim. This doctrine is often used in situations where one party has made a promise or representation, and the other party has taken action based on that promise, leading to potential unfairness if the first party is allowed to change their position. To establish Equitable Estoppel, certain elements must be present: a clear representation or promise, reliance on that representation, and resulting detriment to the relying party. This principle aims to promote fairness and prevent injustice in legal disputes by holding parties accountable for their statements and actions.
