Maryland Uniform Subpoena: Service, Motion to Quash, and Penalties

Maryland subpoena rules live primarily in Rule 2-510 for circuit court civil matters and Rule 3-510 for district court, with Rule 4-265 handling criminal cases. A subpoena is issued by the clerk of the court where the case is pending or, more commonly, signed directly by an attorney of record. It must be served by a non-party adult, either in person or by certified mail with return receipt requested, and it must give the recipient reasonable time to respond. If you receive one, you either comply or file a motion to quash or modify before the compliance date. Ignoring it invites contempt.¹

What a Maryland Subpoena Can Require

A subpoena does one or both of two things. It compels a person to appear and testify at a court proceeding or deposition, and it compels a person to produce documents, electronically stored information, or physical items. A single subpoena can do both at once, ordering someone to show up, answer questions, and bring materials with them.¹

In circuit court, a subpoena is required to compel anyone to attend and testify at a court proceeding, and it is required to force a nonparty to attend a deposition and produce documents or electronic data. For a party the court already has jurisdiction over, a subpoena is permitted but not always strictly necessary for depositions.¹

District court subpoenas under Rule 3-510 work almost identically. The district rule references “documents or other tangible things” rather than separately calling out electronically stored information, so attorneys handling large volumes of digital records generally prefer circuit court where the ESI provisions are explicit.²

Who Can Issue One

The clerk of the court where the action is pending issues the subpoena. Any person entitled to one can request it, and the clerk will either provide a completed subpoena or hand over a blank form to be filled in and returned for the clerk’s signature and seal. A Maryland Bar member in good standing can also receive a form already signed and sealed by the clerk, then fill it in before service.¹

An attorney of record in a pending case can issue a subpoena directly, signing as an officer of the court. This is the streamlined path most litigators use. However it is filled in, the subpoena must identify the court, the case title, and direct the recipient to attend, testify, or produce specified materials at a stated time and place.¹

One point catches people out. You cannot use a subpoena for anything beyond its authorized purposes. Maryland courts can sanction someone who misuses a subpoena form, and those sanctions can include attorney’s fees, reimbursement of the inconvenienced person’s time and expenses, and exclusion of any evidence obtained through the improper subpoena.¹

Serving the Subpoena

A subpoena has no legal effect until it is properly served. Rule 2-510 requires service by someone who is not a party to the case and is at least 18 years old. The server delivers the subpoena directly to the named individual or leaves it at that person’s home or usual place of business with a resident or employee of suitable age and discretion. Maryland also permits service by certified mail with a return receipt requested. When the recipient is a business entity, service goes to an officer, managing agent, or other authorized agent.¹

After service, the server prepares an affidavit documenting the method and date. That affidavit is the official record proving service occurred. Without it, enforcing the subpoena later becomes far more difficult.¹

Reasonable Notice

The rules do not specify an exact number of days between service and the compliance date, but the subpoena must allow reasonable time for the recipient to respond. What counts as reasonable depends on the demand. A simple request to appear and testify needs less lead time than a demand for thousands of pages of financial records. Courts routinely quash subpoenas where the recipient did not get enough notice to realistically comply. If you are issuing one, build in as much lead time as you can.

Witness Fees

A subpoenaed witness is entitled to fees and mileage reimbursement under the same schedule used for witness testimony in court. Maryland does not impose a large daily attendance fee, but witnesses are generally entitled to reimbursement for travel costs, with the exact amount depending on whether the appearance is in circuit court or district court.

Failing to tender the required fees at service can give the witness grounds to challenge the subpoena. If you are on the receiving end and no fees were tendered, raise that issue promptly rather than ignoring the subpoena. Non-compliance still carries risk even when service was arguably deficient.

If You Receive a Subpoena

Once properly served, you must follow the subpoena’s instructions unless you successfully object or the court modifies or quashes it. Compliance means appearing at the time and place named, producing the documents or electronic data described, or both. Deciding on your own that the subpoena is unreasonable and ignoring it is not an option. You have to go through the formal objection process.¹

Filing a Motion to Quash or Modify

The formal challenge is a motion to quash or modify, filed with the court that issued the subpoena. Common grounds include:

Irrelevance — the requested testimony or documents have no meaningful connection to the issues in the case.
Undue burden — compliance would require disproportionate time, expense, or effort relative to the value of the information.
Privilege — the materials are protected by attorney-client privilege, work product doctrine, or another recognized privilege.
Overbreadth — the subpoena sweeps in far more material than is reasonably necessary.

The person objecting bears the burden of explaining why the subpoena should not be enforced. A court can quash the subpoena entirely, narrow its scope, or impose conditions such as requiring the requesting party to cover production costs.¹

File the motion before the compliance date on the subpoena. Waiting until after the deadline and then claiming the subpoena was unreasonable is a weak position.

The Fifth Amendment

A witness subpoenaed to testify can invoke the Fifth Amendment and refuse to answer specific questions if truthful answers would create a real risk of criminal prosecution. The threat must be genuine, not speculative. The privilege applies question by question — a witness does not get to refuse the entire subpoena on Fifth Amendment grounds. You still have to appear and assert the privilege before the court.³

Subpoenas for Medical and Financial Records

Two categories of records carry extra hurdles that will surprise anyone who assumes a subpoena alone is enough.

Medical Records and HIPAA

Under HIPAA, a health care provider or health plan can release protected health information in response to a subpoena only if certain conditions are met. If the subpoena comes from someone other than a judge (a clerk or attorney, for example), the provider must receive evidence that reasonable efforts were made to either notify the patient and give them a chance to object, or obtain a qualified protective order from the court. A court order signed by a judge carries more weight: the provider may release the information described in the order without the additional notification steps.⁴

Attorneys who skip the HIPAA requirements often find the medical provider refuses to produce the records regardless of what the subpoena says.

Financial Records

The federal Right to Financial Privacy Act generally requires that when a government authority serves a subpoena on a financial institution for customer records, the customer must be notified and given an opportunity to object. The institution cannot release records until the government authority certifies compliance with these notification requirements, and a waiting period of at least ten days (or fourteen days if notice was mailed) must pass without the customer filing a motion to quash.⁵

Private litigants are not bound by the Right to Financial Privacy Act in the same way government authorities are, but separate privacy considerations and state-law protections still apply. Requests should be narrowly tailored to the specific accounts and time periods at issue, or they invite objections on relevance and overbreadth.

What Happens If You Ignore a Subpoena

Ignoring a properly served subpoena is one of the faster ways to end up in front of a judge for the wrong reasons. The party that issued the subpoena files a motion for contempt, and the court issues an order to show cause requiring the non-compliant person to appear and explain why they did not obey.¹

Civil contempt in Maryland is coercive rather than punitive. The court imposes sanctions designed to force compliance, such as daily fines or incarceration that continues until the person complies. Comply with the subpoena, and the sanctions stop. Criminal contempt punishes the defiance itself and can result in fixed fines and jail time even after compliance.

Beyond contempt, a court can impose additional sanctions under Rule 2-510 for misuse of subpoenas, including attorney’s fee awards and exclusion of evidence. If your failure to comply with a document subpoena deprives the other side of critical evidence, the court might also draw adverse inferences against you at trial. Challenge an improper subpoena through the objection process. Do not simply ignore it.

Out-of-State Subpoenas Served in Maryland

Maryland has adopted the Uniform Interstate Depositions and Discovery Act, codified in the Courts and Judicial Proceedings Article, Title 9, Subtitle 4. The UIDDA creates a streamlined process for enforcing out-of-state subpoenas in Maryland without filing a separate lawsuit.⁶

The litigant with a case pending in another state first obtains a subpoena from the court where their case is filed. They present that subpoena to the clerk of the Maryland court in the county where the discovery target is located. The Maryland clerk issues a local subpoena that complies with Maryland’s rules, and that local subpoena is served on the witness or document custodian. The out-of-state attorney does not need to be admitted to the Maryland bar or obtain local counsel just to request the subpoena.⁶

If a dispute arises and someone needs to file a motion to enforce, quash, or modify the subpoena, or to seek a protective order, that work must be handled by an attorney licensed in Maryland.

Criminal Cases Follow a Different Rule

Subpoenas in Maryland criminal cases operate under Rule 4-265 rather than Rule 2-510. The criminal rule imposes tighter filing deadlines: a subpoena request must be filed at least nine days before trial in circuit court, or seven days before trial in District Court. Both prosecution and defense can subpoena witnesses, and the same core mechanics apply, but missing the filing deadline can leave an attorney unable to compel key testimony at trial.⁷
