This article investigates the dealings of the Aberdeen courts with foreign merchants and mariners to determine whether special policies, laws or procedures were introduced by magistrates administering justice to parties from different international backgrounds, and whether the merchants themselves developed specific strategies to negotiate crossing legal boundaries in the Scottish context. It concludes that there were few restrictions on the ability of foreigners to receive a fair process before the Aberdeen courts, a conclusion which must be considered in the context of the importance of trade for the men making the decisions at the urban courts, and for Scottish society more generally.
