Insurer Sunk by Vague Policy Language: A Lesson in Contractual Clarity

The Bottom Line

  • Define Your Terms: Insurers and other contract drafters who leave key terms like “Personal Effects” undefined risk having them interpreted in the broadest reasonable way, to their own detriment.
  • The Drafter Bears the Risk: Courts will often apply the contra proferentem principle, meaning any ambiguity in a contract is construed against the party that drafted it. If you wrote it, you are responsible for its clarity.
  • Credibility Can Outweigh In-Person Proof: In cases of total loss where physical inspection is impossible, a credible insured party who provides detailed lists and supporting documents may meet their burden of proof, especially if the insurer cannot provide specific counter-evidence.

The Details

The case revolved around an insurance policy for a yacht that tragically caught fire and sank in the waters near Martinique. The owner, who was living on the vessel with his family for a planned round-the-world trip, had sold his home in Denmark and moved all his household goods aboard. His insurance policy with NAGICO included coverage of up to US$25,000 for “Personal Effects.” When he filed a claim for the total loss of his belongings, the insurer refused to pay, arguing that the term was intended to cover only boat-related items like diving gear, not the owner’s entire household contents.

The Court of First Instance of Sint Maarten sided decisively with the insured owner. The crux of the decision rested on a foundational principle of contract law: ambiguity is the enemy of the drafter. The court noted that the term “Personal Effects” was not defined anywhere in the policy documents. The insurer had not requested a detailed list of items to be covered nor made any reservations when issuing the policy. Given these circumstances, the owner’s interpretation—that the policy covered all his personal belongings on the boat he called home—was deemed entirely reasonable.

The court invoked the contra proferentem rule, a legal doctrine that should be top-of-mind for any CEO or General Counsel. This principle dictates that when a contractual term is ambiguous, it is interpreted against the interests of the party who wrote the contract. Here, NAGICO drafted the unclear policy and was therefore forced to bear the consequences of that lack of clarity. Furthermore, the court found the owner had sufficiently proven his loss by providing detailed lists and receipts totaling well over the $25,000 policy limit, supported by a credibility assessment from the insurer’s own investigators. The insurer’s general challenge to the proof was dismissed as insufficient. The court ordered NAGICO to pay the full policy amount of US$25,000.
