Scrope v Grosvenor (1389) was an early lawsuit relating to the law of arms. One of the earliest heraldic cases brought in England, the case resulted from two different knights in King Richard II's service, Richard Scrope, 1st Baron Scrope of Bolton, and Sir Robert Grosvenor, discovering they were using the same undifferenced coat of arms, blazoned Azure, a bend Or. This had previously gone unnoticed because the armigers' families were from different parts of England. As the law of arms by the 14th century prohibited armigers within the same system of arms from holding the same undifferenced arms, Scrope brought suit against Grosvenor in 1386 to determine who would be allowed to continue using the arms in question; the Court of Chivalry found in Scrope's favour in 1389, and King Richard affirmed the decision the following year.
