Which of the following is NOT a method for handling claim differences?

The selection of class action as the method that is not typically used for handling claim differences is accurate because a class action is primarily a legal process that allows a group of individuals with similar claims to sue a defendant collectively. While it can address collective grievances, it does not directly facilitate the resolution of differences between singular claimants and the insurance company regarding individual claims.

In contrast, negotiation, arbitration, and mediation are all methods specifically designed to resolve disputes between parties, including those that may arise during the claims process.

Negotiation involves direct discussion between the involved parties aiming for a mutually acceptable solution. Arbitration is a more formal process involving an impartial third party who makes a binding decision based on the evidence presented by both sides. Mediation, on the other hand, is a facilitated negotiation where a neutral third party helps to guide the discussion and assist in reaching a voluntary agreement. Each of these methods focuses on dispute resolution, making them relevant in the context of handling claim differences.
