VIII. PRACTICE NOTES AND GUIDANCE

A. Maryland Interrogatory Limits and Counting Rules

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:

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.

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.
