Contra proferentem is a foundational legal principle with particular importance in insurance law. It mandates that any ambiguities in an insurance policy are construed against the insurer and in favor of the insured. The doctrine recognizes that insurance policies generally are contracts of adhesion, in which the insurer wields the “power of the pen,” and the insured is invited to accept the terms of the pre-written agreement with little to no alteration. Contra proferentem mitigates the inherent inequality of an arrangement where insurers generally have sole drafting authority and insureds, often with limited bargaining power, must accept the insurers’ terms as written. By resolving ambiguities in those terms against the insurer, courts are able to counterbalance some of this inequity and find coverage for policyholders.
