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 New Hampshire, the doctrine of estoppel is recognized and can be applied in various legal contexts to prevent a party from asserting a position that is contrary to one previously taken, especially if another party has relied on the initial position to their detriment. This principle is designed to promote fairness and integrity by holding parties accountable for their actions and representations. Estoppel can arise in many areas of law, including contract disputes, property rights, and family law. The specific application of estoppel can depend on the facts of each case, and New Hampshire courts will consider whether the party claiming estoppel has indeed relied on the other party's representation and suffered a detriment as a result. It is important to note that estoppel is an equitable remedy, which means it is at the discretion of the court and is applied to achieve justice rather than being an automatic right.
