OVERSMAN, Scotch law. A person commonly named in a submission, to whom power is given to determine in case the arbiters cannot agree in the sentence; sometimes the nomination of the oversman is left to the arbiters. In either case the oversman has no power to decide, unless the arbiters differ in opinion. Ersk. Pr. L. Scot. 4, 3, 16. The office of an oversman very much resembles that of an umpire.
