CT Gen Stat § 52-156a (2020)
2020 Connecticut General Statutes|Title 52 - Civil Actions|Chapter 899 - Evidence|Section 52-156a - Deposition to perpetuate testimony before action or pending appeal.

 (a)(1) A person who desires to perpetuate testimony regarding any matter that may be cognizable in the Superior Court may file a verified petition in the superior court for the judicial district of the residence of any expected adverse party. The petition shall be entitled in the name of the petitioner and shall show: (A) That the petitioner expects to be a party to an action cognizable in the superior court but is presently unable to bring it or cause it to be brought, (B) the subject matter of the expected action and the petitioner's interest therein, (C) the facts which the petitioner desires to establish by the proposed testimony and the reasons for desiring to perpetuate it, (D) the names or a description of the persons the petitioner expects will be adverse parties and their addresses so far as known, and (E) the names and addresses of the persons to be examined and the substance of the testimony which the petitioner expects to elicit from each, and shall ask for an order authorizing the petitioner to take the depositions of the persons to be examined named in the petition, for the purpose of perpetuating their testimony.(2) The petitioner shall thereafter serve a notice upon each person named in the petition as an expected adverse party, together with a copy of the petition, stating that the petitioner will apply to the court, at a time and place named therein, for the order described in the petition. At least twenty days before the date of hearing the notice shall be served in the manner provided by section 52-57; but if such service cannot with due diligence be made upon any expected adverse party named in the petition, the court may make such order as is just for service by publication or otherwise, and shall appoint, for persons not served in the manner provided by section 52-57, an attorney who shall represent them, and, in case they are not otherwise represented, shall cross-examine the deponent.(3) If the court is satisfied that the perpetuation of the testimony may prevent a failure or delay of justice, it shall make an order designating or describing the persons whose depositions may be taken and specifying the subject matter of the examination and whether the depositions shall be taken upon oral examination or written interrogatories. The depositions may then be taken in accordance with this section; and the court may make orders for the production of documents and things and the entry upon land for inspection and other purposes, and for the physical or mental examination of persons. For the purpose of applying this section to depositions for perpetuating testimony, each reference in this section to the court in which the action is pending shall be deemed to refer to the court in which the petition for such deposition was filed.(4) If a deposition to perpetuate testimony is taken under this section, it may be used in any action involving the same subject matter subsequently brought in the Superior Court.(b) If an appeal has been taken from a judgment of the Superior Court or before the taking of an appeal if the time therefor has not expired, the superior court in which the judgment was rendered may allow the taking of the depositions of witnesses to perpetuate their testimony for use in the event of further proceedings in the Appellate or Supreme Court. In such case the party who desires to perpetuate the testimony may make a motion in the Superior Court for leave to take the depositions, upon the same notice and service thereof as if the action was pending in the Superior Court. The motion shall show (1) the names and addresses of persons to be examined and the substance of the testimony which the party expects to elicit from each; and (2) the reasons for perpetuating their testimony. If the court finds that the perpetuation of the testimony is proper to avoid a failure or delay of justice, it may make an order allowing the depositions to be taken and may make orders for the production of documents and things and the entry upon land for inspection and other purposes, and for the physical or mental examination of persons, and thereupon the depositions may be taken and used in the same manner and under the same conditions as are prescribed in this section for depositions taken in actions pending in the Superior Court.(P.A. 91-324, S. 14.)Cited. 229 C. 716; 230 C. 1.
