VIII. PRACTICE NOTES AND GUIDANCE
A. Maryland Interrogatory Limits and Counting Rules
Under Md. Rule 2-421(a), a party may serve a cumulative total of not more than 30 interrogatories on any other party. Interrogatories are counted separately regardless of how they are grouped, combined, or arranged, and even though subsidiary or incidental to or dependent upon other interrogatories. This means each discrete subpart counts as a separate interrogatory toward the 30-question limit.
District Court: In Maryland District Court, the limit is reduced to 15 interrogatories. Md. Rule 3-421.
B. Response Deadlines and Extensions
- Standard deadline: 30 days after service. Md. Rule 2-421(b).
- Early service: If interrogatories are served before the responding party's initial pleading or motion is due, the response deadline is 15 days after the initial pleading/motion deadline, whichever is later.
- Extensions: Parties may stipulate to extensions of time under Md. Rule 2-401(c). Court approval may be required if the extension would affect other scheduling order deadlines.
C. Business Records Option
Under Md. Rule 2-421(c), if the answer to an interrogatory may be derived from the responding party's business records, and the burden of deriving the answer is substantially the same for the propounding party as for the responding party, the responding party may specify the records from which the answer can be derived and provide a reasonable opportunity to examine and copy them.
D. Corporate Party Responses
When the responding party is a corporation, partnership, or governmental agency, an officer or agent must furnish information available to the entity. See Md. Rule 2-412 regarding answers by corporate officers.
E. Motion to Compel
If the responding party fails to answer or provides evasive or incomplete answers, the propounding party may file a motion to compel under Md. Rule 2-432. The motion must include a certification that the movant made a good-faith effort to resolve the dispute before filing.
F. Sanctions
Under Md. Rule 2-433, sanctions for failure to comply with discovery orders may include:
☐ An order that designated facts be taken as established
☐ An order refusing to allow the disobedient party to support or oppose claims or defenses
☐ An order striking pleadings or parts thereof
☐ An order staying proceedings until compliance
☐ An order dismissing the action or entering a default judgment
☐ An order holding the party in contempt of court
☐ An award of reasonable expenses, including attorney fees
G. E-Discovery Considerations
Maryland has adopted rules addressing ESI. Under Md. Rule 2-402(b), ESI is discoverable from any source. Parties should discuss ESI protocols early in the case, including preservation obligations, search methodologies, format of production, and cost allocation.
H. Form Interrogatories
Maryland provides standard form interrogatories in the Appendix to the Maryland Rules. Practitioners may use these forms as a starting point and supplement with case-specific questions, provided the total does not exceed 30.

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.
