Each matter of which an admission is requested shall be separately set forth.
A party shall not serve more than 30 requests for admission on any other party except upon agreement of the parties or leave of court granted upon a showing of good cause. A motion for leave of court to serve more than 30 requests for admission must be in writing and shall set forth the proposed requests and the reasons establishing good cause for their use.
If objection is made, the reasons therefor shall be stated. The answer shall specifically deny the matter or set forth in detail the reasons why the answering party cannot truthfully admit or deny the matter. A denial shall fairly meet the substance of the requested admission, and when good faith requires that a party qualify the party's answer or deny only a part of the matter of which an admission is requested, the party shall specify so much of it as is true and qualify or deny the remainder. An answering party may not give lack of information or knowledge as a reason for failure to admit or deny unless the party states that the party has made reasonable inquiry and that the information known or readily obtainable by the party is insufficient to enable the party to admit or deny. A party who considers that a matter of which an admission has been requested presents a genuine issue for trial may not, on that ground alone, object to the request; the party may, subject to the provisions of rule 1.517(3) deny the matter or set forth reasons why the party cannot admit or deny it.
