In plain English
Estoppel is about fairness in hindsight. If an insurer’s words or actions led an insured to act in a particular way, the insurer may be barred from taking a contrary position later, even where the policy language would otherwise permit it.
The doctrine focuses on reliance rather than intent. It does not ask whether the insurer meant to give up a right; it asks whether reversing course now would unfairly harm someone who reasonably relied on what was communicated.
Why the exam tests it
Estoppel appears in authority and ethics questions because a single careless statement by an adjuster can create it. The exam wants candidates who understand why staying inside granted authority protects the file.
The trap
Requiring intent. Estoppel can arise without any intention to surrender a right. Answer choices that hinge on what the insurer meant to do are usually describing waiver instead.
Worked example
An adjuster states that repairs are approved before completing the coverage analysis. The insured hires a contractor and incurs cost in reliance on that statement. Even if a defense existed, the insurer may be estopped from relying on it, which is precisely why coverage statements belong to the person holding that authority.
