Estoppel is a legal principle that prevents a person or entity from asserting a legal right or taking a legal position that contradicts or is inconsistent with its earlier position, behavior, or agreement. The person or entity is said to be “estopped” from changing its position, behavior, or agreement because another person or entity has relied on its earlier position, behavior, or agreement (detrimental reliance).
In Maryland, the legal principle of estoppel is recognized and can be applied in various contexts, including contract disputes, property law, and employment law, among others. Estoppel prevents a party from asserting a claim or a defense that contradicts their previous statements or actions when the other party has relied on those statements or actions to their detriment. There are different types of estoppel, such as promissory estoppel, equitable estoppel, and estoppel by deed. Maryland courts will consider whether there was a representation or conduct that led to a reasonable reliance by the other party, and whether that reliance resulted in a detriment. If these elements are met, the party may be estopped from changing their position. This principle is designed to promote fairness and integrity by holding parties accountable for their conduct and representations.
