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 Arkansas, estoppel is a legal doctrine that operates to bar a party from denying or asserting anything to the contrary of that which has, in contemplation of law, been established as the truth, either by the acts of judicial or legislative officers or by their own deed or representations, express or implied. This principle is often applied in cases where a party's actions or statements have led another party to take a certain position or action to their detriment. Arkansas courts recognize various forms of estoppel, including equitable estoppel, promissory estoppel, and estoppel by deed, among others. The specific application of estoppel can depend on the context in which it arises, such as in contract disputes, property issues, or family law matters. To invoke estoppel successfully in Arkansas, the party claiming estoppel must generally demonstrate that they relied on the other party's representation and suffered a detriment as a result of that reliance.
