S.C. R. Civ. P. 27
At present Code §§19-17-40 et seq. provide for depositions de bene esse. This proposal, drawn from Federal Rule 27 with minor modifications, provides an easy method for perpetuating testimony prior to the filing of suit. It has been consistently held that it is not a method of discovery before suit is brought. As provided in paragraph (a)(1) the verified petition must establish that the petitioner expects to be a party but is unable to do so at the present time, and also must specify the proposed testimony and the names of the deponents, which indicates that the petitioner must know in advance the information sought to be perpetuated. In appropriate cases the rule also permits the use of Rules 34 and 35 if necessary. There are similar provisions for retaining the testimony if the case is on appeal.
