Section 31:
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.
(2) If the instrument has been registered under the Indian Registration Act, 1908 (16 of 1908), the
court shall also send a copy of its decree to the officer in whose office the instrument has been so
registered; and such officer shall note on the copy of the instrument contained in his books the fact of its
cancellation.
