estoppel by conduct

Estoppel by conduct is a legal principle that prevents someone from going back on a promise or an agreed action if their behavior has led another person to rely on it. Essentially, if one party's words or actions suggest a specific understanding, and the other party relies on that, the first party may be legally prevented from later denying it. This protects fairness by ensuring people can't change their position after causing others to act based on their conduct.
