(B) the genuineness of any described documents.
(3) Time to Respond; Effect of Not Responding. A matter is admitted unless, within 30 days after being served, the party to whom the request is directed serves on the requesting party a written answer or objection addressed to the matter and signed by the party or its attorney. A shorter or longer time for responding may be stipulated to under Rule 29 or be ordered by the court.
(4) Answer. If a matter is not admitted, the answer must specifically deny it or state in detail why the answering party cannot truthfully admit or deny it. A denial must fairly respond to the substance of the matter; and when good faith requires that a party qualify an answer or deny only a part of a matter, the answer must specify the part admitted and qualify or deny the rest. The answering party may assert lack of knowledge or information as a reason for failing to admit or deny only if the party states that it has made reasonable inquiry and that the information it knows or can readily obtain is insufficient to enable it to admit or deny.
(5) Objections. The grounds for objecting to a request must be stated. A party must not object solely on the ground that the request presents a genuine issue for trial.
(6) Motion Regarding the Sufficiency of an Answer or Objection. The requesting party may move to determine the sufficiency of an answer or objection. Unless the court finds an objection justified, it must order that an answer be served. On finding that an answer does not comply with this rule, the court may order either that the matter is admitted or that an amended answer be served. The court may defer its final decision until a pretrial conference or a specified time before trial. Rule 37(a)(5) applies to an award of expenses.
