The proceeding quia timet is sustained in equity for the purpose of causing to be delivered and canceled any instrument which has answered the object of its creation or any forged or other iniquitous deed or other writing which, though not enforced at the time, either casts a cloud over the complainant's title or otherwise subjects him to future liability or present annoyance, and the cancellation of which is necessary to his perfect protection.
