P.R. Laws Ap. tit. 32A, § III, Rule 27.8
(a) The person before whom the deposition is taken or, in his absence, the person recording the examination shall certify on the deposition that the witness was duly sworn and that the deposition is a true and exact transcript of the testimony given by the witness. He shall then securely seal the deposition in an envelope indorsed with the title of the action and marked “Deposition of (here insert name of witness)” and shall promptly deliver it to the party taking it, who shall in turn be obliged to notify all other parties that the deposition is in his possession. Furthermore, he shall be obliged to keep the deposition and produce it at the trial, unless it is not to be used in the trial, in accordance with Rule 27.6.
(b) Documents and things produced for inspection during the examination of the witness shall, upon request of a party, be marked for identification and annexed to the transcript of the deposition. Said documents and things may be inspected and copied by any party. The person producing the documents or things may substitute copies to be marked for identification, if he affords to all parties fair opportunity to verify that the copies are true and exact to the originals. Also, if the person producing the documents or things requests their return, each party will be given an opportunity to inspect and copy them, and they will be returned to the person producing them after being duly marked by the parties and the materials may then be used in the same manner as if annexed to the deposition.
(c) Upon payment of a prescribed fee therefor, the person before whom the deposition is taken or, in his absence, the person taking or recording the examination shall furnish a copy of the deposition to any party to the action or to the deponent.
