Private records, books of account, and documentary evidence in general present an evidenciary problem in litigation if one, in proving his case, must use the records and books of account of a third person outside the jurisdiction of the forum. A subpoena duces tecum is limited to the boundaries of the state of the forum. Written evidence in the hands of a third person outside the state where the litigation is being pursued can only be obtained by permission of the owner, and even if the owner does permit the transportation of records and books of account necessary to the proof of a suit, the problem of inconvenience and expense arises which invariably results in a burden to the litigants.
