 According to the Law of Arms in most heraldic jurisdictions, usage of a pre-existing coat of arms must be predicated on some form of relation.Typically, inheritance of arms flows through the male line, though in many traditions it may flow through the female line as well.In heraldry, a "bucket shop" is a company that will sell a coat of arms associated with the customer's surname, regardless of whether the customer can actually claim a relation to the original armiger.
