(a) Motion for Order Compelling Discovery. When discovery has been permitted by the Court, or by these rules, a party, upon reasonable notice to other parties and all persons affected thereby, may apply for an order compelling discovery as follows:
(1) Appropriate Court. A Motion for an order to a party may be made to the Court or, alternatively, on matters relating to a deposition taken outside the State of Delaware, to a court in the state where the deposition is being taken. A Motion for an order to a deponent who is not a party shall be made to a court in the state where the deposition is being taken. The motion must include a certification or affidavit that the movant has in good faith conferred or attempted to confer with the other affected parties in an effort to resolve the dispute without court action.
(2) Motion. If a deponent fails to answer a question propounded or submitted under Rule 30 or 31, or a corporation or other entity fails to make a designation under Rule 30(b)(6) or 31(a), or a party fails to answer an interrogatory submitted under Rule 33, or if a party, in response to a request for inspection submitted under Rule 34, fails to respond that inspection will be permitted as requested or fails to permit inspection as requested, the discovering party may move for an order compelling an answer, or a designation, or an order compelling inspection in accordance with the request. When taking a deposition on oral examination, the proponent of the question may complete or adjourn the examination before applying for an order.
(3) Evasive or Incomplete Answer or Response. For purposes of this paragraph an evasive or incomplete answer or response is to be treated as a failure to answer or respond.
(4) Expenses and Sanctions.
(A) If the motion is granted or if the disclosure or requested discovery is provided after the motion was filed, the Court shall, after affording an opportunity to be heard, require the party or deponent whose conduct necessitated the motion or the party or attorney advising such conduct or both of them to pay to the moving party the reasonable expenses incurred in obtaining the order, including the attorney's fees, unless the Court finds that the opposition to the motion was substantially justified or that other circumstances make an award of expenses unjust.
(B) If the motion is denied, the Court may enter any protective order authorized under Rule 26(h) and shall, after an opportunity to be heard, require the moving party or the attorney advising the motion or both of them to pay to the party or deponent who opposed the motion the reasonable expenses incurred in opposing the motion, including attorney's fees, unless the Court finds that the making of the motion was substantially justified or that other circumstances make an award of expenses unjust.
(C) If the motion is granted in part and denied in part, the Court may enter any protective order authorized under Rule 26(h) and may, after affording an opportunity to be heard, apportion the reasonable expenses incurred in relation to the motion among the parties and persons in a just manner.
(b) Failure to Comply With Order.
(1) Omitted.
(2) Sanctions by Court. If a party or an officer, director, or managing agent of a party or a person designated under Rule 30(b) (6) or 31(a) to testify on behalf of a party fails to obey an order to provide or permit discovery, including an order made under paragraph (a) of this rule or Rule 35, the Court may make such orders in regard to the failure as are just, and among others the following:
(A) An order that the matters regarding which the order was made or any other designated facts shall be taken to be established for the purposes of the action in accordance with the claim of the party obtaining the order;
(B) An order refusing to allow the disobedient party to support or oppose designated claims or defenses, or prohibiting that party from introducing designated matters in evidence;
(C) An order striking out pleadings or parts thereof, or staying further proceedings until the order is obeyed, or dismissing the action or proceeding or any part thereof, or rendering a judgment by default against the disobedient party;
(D) In lieu of any of the foregoing orders or in addition thereto, an order treating as a contempt of court the failure to obey any orders except an order to submit to a physical or mental examination;
(E) Where a party has failed to comply with an order under Rule 35(a) requiring that party to produce another for examination, such orders as are listed in paragraphs (A), (B), and (C) of this subdivision, unless the party failing to comply show that that party is unable to produce such person for examination. In lieu of any of the foregoing orders or in addition thereto, the Court shall require the party failing to obey the order or the attorney advising that party or both to pay the reasonable expenses, including attorney's fees, caused by the failure, unless the Court finds that the failure was substantially justified or that other circumstances made an award of expenses unjust.
(c) Expenses on Failure to Admit. When discovery has been permitted by the Court, if a party fails to admit the genuineness of any document or the truth of any matter as requested under Rule 36, and if the party requesting the admissions thereafter proves the genuineness of the document or the truth of the matter, the requesting party may apply to the Court for an order requiring the other party to pay the reasonable expenses incurred in making that proof, including reasonable attorney's fees. The Court shall make the order unless it finds that (1) the request was held objectionable pursuant to Rule 36(a), or (2) the admission sought was of no substantial importance, or (3) the party failing to admit had reasonable ground to anticipate prevailing on the matter, or (4) there were other good reasons for the failure to admit.
(d) Failure of Party to Attend at Own Deposition or Serve Answers to Interrogatories or Respond to Request for Inspection. When discovery has been permitted by the Court, if a party or an officer, director, or managing agent of a party or a person designated under Rule 30(b)(6) or 31(a) to testify on behalf of a party fails (1) to appear before the officer who is to take the deposition, after being served with a proper notice, or (2) to serve answers or objections to interrogatories submitted under Rule 33, after proper service of the interrogatories, or (3) to serve a written response to a request for inspection submitted under Rule 34, after proper service of the request, the Court in which the action is pending on motion may make such orders in regard to the failure as are just, and among others it may take any action authorized under paragraph (A), (B), and (C) of subdivision (b)(2) of this rule. In lieu of any order or in addition thereto, the Court shall require the party failing to act or the attorney advising that that party or both to pay the reasonable expenses, including attorney's fees, caused by the failure, unless the Court finds that the failure was substantially justified or that other circumstances make an award of expenses unjust. The failure to act described in this paragraph may not be excused on the ground that the discovery sought is objectionable unless the party failing to act has applied for a protective order as provided by Rule 26(h).
(e) Failure or Neglect to File Discovery Material. If any discovery material required to be filed with the Court or a party is not served and/or filed within the time and in the manner required by these Rules or in accordance with any order of the Court or stipulation of counsel, the Court may, in its discretion, dismiss the proceeding if the petitioner is in default, consider the motion as abandoned, or summarily deny or grant the motion, such as the situation may present itself, or take such other action as it deems necessary to expedite the disposition of the case. Upon the showing of good cause in writing, the Court may permit late filing of such papers and pursuant to a written rule or order.

Plain-English Summary

The motion to compel. Where discovery has been permitted, a party may on reasonable notice move for an order compelling it — where a deponent fails to answer a question under Rule 30 or 31, an entity fails to make a designation, a party fails to answer an interrogatory, or a party fails to respond to a request for inspection. An evasive or incomplete answer is treated as a failure to answer.

Which court. A motion about a party goes to this court, or, on matters relating to a deposition taken outside Delaware, to the court where the deposition is being taken.

Expenses, both ways. If the motion is granted — or if the discovery is provided after it was filed — the court shall, after an opportunity to be heard, require the party whose conduct necessitated the motion to pay the movant's reasonable expenses including attorney's fees, unless the opposition was substantially justified or other circumstances make an award unjust. If the motion is denied, the same obligation runs the other way, against the moving party or the attorney who advised the motion.

That symmetry is the design. A motion to compel is not a free shot; both bringing one and resisting one carry a cost if you are wrong without justification.

Disobedience. Where a party fails to obey an order, the court may make the orders the rule provides — treating matters as established, refusing to allow claims or defences, striking pleadings, staying proceedings, dismissing the action or entering judgment by default, and treating the failure as contempt.

Frequently Asked Questions

What do I do if the other side ignores discovery?

Move for an order compelling it. An evasive or incomplete answer or response is treated as a failure to answer or respond.

Who pays for a motion to compel?

If it is granted, or the discovery is provided after it was filed, the party whose conduct necessitated it pays the movant's reasonable expenses including attorney's fees, unless the opposition was substantially justified or other circumstances make an award unjust. If it is denied, the moving party or the attorney advising it pays the other side's.

What happens if someone disobeys a discovery order?

The court may treat matters as established, refuse to allow claims or defences, strike pleadings, stay the proceedings, dismiss the action or enter a default judgment, and may treat the failure as a contempt of court.
