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 Kansas, estoppel is a legal doctrine that can be invoked in various contexts, such as contract disputes, property rights, and other civil matters. The principle of estoppel prevents a party from asserting a claim or a defense that contradicts their previous statements or actions if the other party has relied upon those statements or actions to their detriment. This is to ensure fairness and prevent injustice due to inconsistent behavior. Kansas courts may apply different types of estoppel, including promissory estoppel, equitable estoppel, and estoppel by deed, depending on the circumstances of the case. The application of estoppel is fact-specific and requires a showing that the party claiming estoppel reasonably relied on the other party's representations and suffered harm as a result of that reliance.
