When cancellation may be ordered.—(1) Any person against whom a written instrument is void or voidable, and who has reasonable apprehension that such instrument, if left outstanding may cause him serious injury, may sue to have it adjudged void or voidable; and the court may, in its discretion, so adjudge it and order it to be delivered up and cancelled.
