804.015(2)(2) Unless ordered by the court, a prisoner in an action or special proceeding may not obtain discovery before the court receives a copy of the answer or other responsive pleading in the action commenced by the prisoner. If a defendant submits a motion to dismiss or a motion for summary judgment, no discovery may be obtained until the court decides that the prisoner has a reasonable opportunity to prevail on the merits, or until the court decides the merits of the motion, unless the court orders a party to submit to discovery.

804.015(3)(3) If a court allows a prisoner to obtain discovery under sub. (2) before the court decides that the prisoner has a reasonable opportunity to prevail on the merits, receives a copy of the answer or other responsive pleading in the action, or decides the merits of a motion to dismiss or a motion for summary judgment, the court order shall be narrowly tailored to limit the discovery to allow only discovery that is essential to enable the prisoner to obtain the evidence necessary to his or her case. The court shall limit the discovery so as to provide a minimal intrusion in the activities of any person subject to discovery under this subsection.

804.015(4)(4) If a prisoner commences an action or special proceeding, the court shall limit the number of requests for interrogatories, production of documents or admissions to 15, unless good cause is shown for any additional requests. This number may not be expanded by the use of subparts to the interrogatories.

804.015(5)(5) This section does not apply when the prisoner appears by an attorney who is licensed to practice law in this state.

804.02(1)(1) Before action.

804.02(1)(a)(a) Petition. A person who desires to perpetuate personal testimony or that of another person regarding any matter that may be cognizable in any court of this state may file a verified petition in any such court in this state. The petition shall be entitled in the name of the petitioner and shall show that the petitioner expects to be a party to an action; the subject matter of the expected action and the petitioner’s interest therein; the facts which the petitioner desires to establish by the proposed testimony and the petitioner’s reasons for desiring to perpetuate it; the names or a description of the persons the petitioner expects will be adverse parties and their addresses so far as known; and 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.

804.02(1)(b)(b) Notice and service. 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 move the court, at a time and place named therein, for the order described in the petition. At least 20 days before the date of hearing the notice shall be served either within or without the state in the manner provided in s. 801.11 for service of summons; 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 in s. 801.11, an attorney who shall represent them, and, in case they are not otherwise represented, shall cross-examine the deponent. If any expected adverse party is a minor or is an individual adjudicated or alleged to be incompetent, s. 803.01 (3) applies.

804.02(1)(c)(c) Order and examination. 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 chapter; and the court may make orders of the character provided for by ss. 804.09 and 804.10. For the purpose of applying this chapter to depositions for perpetuating testimony, each reference therein 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.

804.02(1)(d)(d) Use of deposition. If a deposition to perpetuate testimony is taken under this section, or if, although not so taken, it would be otherwise admissible in the courts of this state, it may be used in any action involving the same subject matter subsequently brought in this state in accordance with s. 804.07.

804.02(2)(2) Pending appeal.

804.02(2)(a)(a) If an appeal has been taken from a judgment of a court of this state or before the taking of an appeal if the time therefor has not expired, the 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 court.

804.02(2)(b)(b) In such case, the party who desires to perpetuate the testimony may make a motion in the court for leave to take the depositions, upon the same notice and service thereof as if the action was pending in the court. The motion shall show all of the following:

804.02(2)(c)(c) 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 of the character provided for by ss. 804.09 and 804.10 and thereupon the depositions may be taken and used in the same manner and under the same conditions as are prescribed in this chapter for depositions taken in actions pending in the court.

804.03(1)(1) Within the United States. Within the United States or within a territory or insular possession subject to the dominion of the United States, depositions shall be taken before an officer authorized to administer oaths by the laws of the United States or of this state or of the place where the examination is held, or before a person appointed by the court in which the action is pending. A person so appointed has power to administer oaths and take testimony.

804.03(2)(2) In foreign countries. In a foreign country, depositions may be taken on notice before a person authorized to administer oaths in the place in which the examination is held, either by the law thereof or by the law of the United States; before a person commissioned by the court, and a person so commissioned shall have the power by virtue of the commission to administer any necessary oath and take testimony; or pursuant to a letter rogatory. A commission or a letter rogatory shall be issued on motion and notice and on terms that are just and appropriate. It is not requisite to the issuance of a commission or a letter rogatory that the taking of the deposition in any other manner is impracticable or inconvenient; and both a commission and a letter rogatory may be issued in proper cases. A notice or commission may designate the person before whom the deposition is to be taken either by name or descriptive title. A letter rogatory may be addressed “To the Appropriate Authority in (here name the country)”. Evidence obtained in response to a letter rogatory need not be excluded merely for the reason that it is not a verbatim transcript or that the testimony was not taken under oath or for any similar departure from the requirements for depositions taken within the United States under this chapter.
