P.R. Laws Ap. tit. 32A, § III, Rule 27.6
A witness may be questioned on direct examination and cross-examination. A person designated under Rule 25 shall put the witness on oath and shall personally, or by someone acting under his direction, record the testimony of the witness. If the person before whom the deposition is taken is not present, in accordance with Rule 25.1, the person taking down the deposition shall leave record of it. The deposition shall be recorded by stenographic or similar means, or by any other means as directed by the court pursuant to Rule 27.4.
A party not interested in a transcription of the deposition shall so state before the court by motion to that effect, giving the reasons therefor and specifying that said deposition will not be used at trial. If the motion is granted, the deposition shall not be transcribed and shall remain under the custody of the court.
All objections made at the time of the examination shall be entered in the record and the evidence objected to shall be taken subject to the decision of the court.
In lieu of participating in the oral examination, a party may serve written questions in a sealed envelope on the person before whom the deposition is to be taken, who will in turn transmit them to the witness.
