Maryland discovery deadlines: 30 days, or 15 after your pleading was due — whichever is later

Maryland uses 30 days across all three written discovery devices, which is the common figure. What is not common is the alternative that sits beside it in every one of the three rules: 15 days after the date on which that party's initial pleading or motion is required, whichever is later.

That second branch is the defendant's protection, and it is easy to overlook because it is phrased as part of the same sentence rather than as a separate subsection.

The three deadlines

The consistency is helpful: one formula, three devices.

Interrogatories, and the limit of 30

Md. Rule 2-421(a):

Availability; number. — Any party may serve written interrogatories directed to any other party. Unless the court orders otherwise, a party may serve one or more sets having a cumulative total of not more than 30 interrogatories to be answered by the same party. Interrogatories, however grouped, combined, or arranged and even though subsidiary or incidental to or dependent upon other interrogatories, shall be counted separately. Each form interrogatory contained in the Appendix to these Rules shall count as a single interrogatory.

Three points.

Thirty is a cumulative total, not a per-set allowance. Serving three sets of fifteen does not work.

And subparts count. The rule forecloses the usual drafting trick in unusually thorough language: "however grouped, combined, or arranged and even though subsidiary or incidental to or dependent upon other interrogatories."

But form interrogatories count as one each. That is a meaningful concession — Maryland's Appendix form interrogatories are substantial, and each consumes only a single unit of the thirty.

Rule 2-421(b):

Response. — The party to whom the interrogatories are directed shall serve a response within 30 days after service of the interrogatories or within 15 days after the date on which that party's initial pleading or motion is required, whichever is later. The response shall answer each interrogatory separately and fully in writing under oath, or shall state fully the grounds for refusal to answer any interrogatory. The response shall set forth each interrogatory followed by its answer. An answer shall include all information available to the party directly or through agents, representatives, or attorneys. The response shall be signed by the party making it.

Two formal requirements worth flagging: the response must repeat each interrogatory followed by its answer, and it must be signed by the party — not merely by counsel — and given under oath.

Document requests

Md. Rule 2-422(c):

Response. — The party to whom a request is directed shall serve a written response within 30 days after service of the request or within 15 days after the date on which that party's initial pleading or motion is required, whichever is later.

Same formula. Rule 2-422(b) also requires the request itself to describe each item or category "with reasonable particularity" and to "specify a reasonable time, place, and manner of making the inspection" — so an unreasonable specification is a ground to object rather than something to comply with.

Requests for admission, and the automatic consequence

Md. Rule 2-424(b):

Response. — Each matter of which an admission is requested shall be deemed admitted unless, within 30 days after service of the request or within 15 days after the date on which that party's initial pleading or motion is required, whichever is later, the party to whom the request is directed serves a response signed by the party or the party's attorney. As to each matter of which an admission is requested, the response shall set forth each request for admission and shall specify an objection, or shall admit or deny the matter, or shall set forth in detail the reason why the respondent cannot truthfully admit or deny it. The reasons for any objection shall be stated. A denial shall fairly meet the substance of the requested admission, and when good faith requires that a party qualify an answer or deny only a part of the matter of which an ad[mission is requested] …

The consequence is automatic — no motion, no order. Thirty days pass and the matter is admitted.

Note one difference from the interrogatory rule: a response to requests for admission may be signed by the party or the party's attorney. Interrogatory answers must be signed by the party, under oath.

Rule 2-424(a) also requires that copies of documents be served with the request unless already furnished, and that each matter be separately set forth.

Working out the second branch

The "15 days after the date on which that party's initial pleading or motion is required" clause needs a date that is not on any discovery document, so it has to be computed.

For a defendant served in Maryland, the initial pleading is due 30 days after service of process. Add 15, and the floor is 45 days from service of the summons and complaint. A defendant served out of state but within the United States has 60 days to plead, so the floor is 75.

Then compare that floor with 30 days from the discovery request and take the later.

The practical upshot: discovery served with the complaint does not have to be answered in 30 days. A plaintiff who serves interrogatories alongside process and calendars 30 days will be waiting.

When responses are inadequate

Rule 2-432 governs motions on a failure to provide discovery, and Rule 2-433 the sanctions available. Maryland distinguishes between a complete failure to respond, which supports an immediate motion for sanctions, and an inadequate response, which ordinarily requires a motion to compel first — a distinction worth checking before choosing which motion to file.

How Maryland compares

A short checklist

1. Compute both dates for every response — 30 days from service, and 15 days after your initial pleading was due — and take the later.
2. If you were served with discovery alongside process, the floor almost certainly governs.
3. Count the interrogatories cumulatively, including subparts. Thirty is the total across all sets.
4. Do not count form interrogatories individually — each counts as one.
5. Set out each interrogatory followed by its answer. The rule requires the question to be reproduced.
6. Have the party sign interrogatory answers under oath, not just counsel.
7. Treat requests for admission as the urgent pile. Missing the deadline admits the matter automatically, with no motion required.
8. Make denials fairly meet the substance of what was asked, and qualify where good faith requires it.
9. Before moving, work out whether you are dealing with no response or an inadequate one — Rules 2-432 and 2-433 treat them differently.
