Scrope v Grosvenor (1389) was one of the earliest heraldic law of arms cases brought in England. The case resulted from two different families found using the same undifferenced coat of arms. By the 12th and 13th centuries, the composition of coats of arms consisted of only one charge and two tinctures. However, this simplicity meant there were often times when unrelated families ended up bearing the same designs. By the 14th century, the sharing of coat of arms had become less tolerated. In many cases, the monarch was the final arbiter on any decision.
