👉 A dupe, or a duplicate, is an individual who has the same name as another individual. In the context of legal systems, a dupe would be someone who claims to have rights and responsibilities that are not actually theirs. For example, in a country where a person can claim to be a citizen but also have a dual citizenship with another nation, they could potentially be considered a dupe because their name is identical to the one claiming to hold certain rights or responsibilities.
