VIII. PRACTICE NOTES
1. Court Selection. This template is drafted for the Delaware Superior Court. If the matter is pending in a different Delaware trial court (e.g., Court of Chancery, Court of Common Pleas, Justice of the Peace Court), modify the caption and verify the applicable rules. The Court of Chancery, for example, has its own discovery rules.
2. Interrogatory Limit. Del. Super. Ct. Civ. R. 33(a) establishes the numerical limit for interrogatories including sub-parts. Verify the current limit before propounding. If additional interrogatories are needed, seek a stipulation under Rule 29 or a court order under Rule 33(a).
3. Response Deadline. The standard response deadline is thirty (30) days after service; forty-five (45) days if served with the summons and complaint. If service is by mail, add three (3) days under Rule 6(e). Calendar the deadline immediately.
4. Waiver of Objections. Under Del. Super. Ct. Civ. R. 33(b)(4), any ground for objection not stated in a timely objection is waived unless the Court excuses the failure for good cause. Advise opposing counsel of this consequence.
5. Claw-Back for Inadvertent Production. Delaware recognizes claw-back protections under Rule 26(b)(5)(B) and Delaware Rule of Evidence 502(b). Consider including a claw-back provision in the parties' discovery plan or protective order.
6. E-Filing. Delaware Superior Court uses File & ServeXpress for electronic filing and service. Confirm the e-filing requirements for the assigned county. Ensure the certificate of service reflects the method actually used.
7. Delaware Bar Number. Delaware counsel must include their Supreme Court of Delaware Bar Number on all filings and certificates of service.
8. Motion to Compel. If Defendant fails to timely respond or provides evasive or incomplete answers, Plaintiff may file a motion to compel under Del. Super. Ct. Civ. R. 37(a). Include certification that counsel conferred or attempted to confer in good faith.
9. Sanctions. Failure to serve timely, complete, and verified responses may result in sanctions under Del. Super. Ct. Civ. R. 37(b), including striking pleadings, precluding evidence, awarding attorney fees, or entering default.
10. Scheduling Order. Review the Court's scheduling or case management order for any discovery-specific provisions, including ESI protocols, privilege claw-back agreements, and discovery cutoff dates. Align interrogatory practice with these requirements.
11. Coordinating Discovery. Consider serving interrogatories in conjunction with requests for production (Rule 34) and requests for admission (Rule 36) to maximize the efficiency of discovery within applicable limits.

About This Template
These are the filings that drive a lawsuit through the system: complaints, answers, motions, briefs, discovery requests and responses, and post-judgment papers. Each has its own format requirements under federal and state procedural rules, and each has a deadline that cannot be missed without consequences. Clean, procedurally correct filings move a case forward; sloppy ones invite motions to strike, amended responses, and avoidable delays.
Important Notice
This template is provided for informational purposes. It is not legal advice. We recommend having an attorney review any legal document before signing, especially for high-value or complex matters.
