In property law, a legal doctrine prevents an individual from asserting rights that contradict prior actions, statements, or representations. It essentially stops someone from going back on their word or conduct if another party has reasonably relied on that word or conduct to their detriment. For instance, if a landlord consistently accepts rent payments after the due date without penalty, they may be barred from suddenly enforcing a late fee without prior notice because the tenant has come to rely on the established pattern.
This legal principle is vital in maintaining fairness and preventing injustice within property transactions. Its application provides security to parties who act in good faith, relying on the assurances or behavior of others. Historically, it has served as a tool to ensure equitable outcomes in disputes where strict adherence to contractual terms would lead to unfair results, fostering trust and stability in property dealings.
