What Is a Trial Subpoena and When Is It Used in a New York Personal Injury Case?

A trial subpoena is a court-authorized legal order. It requires a person to appear at trial to testify, produce documents, or both. In New York, subpoenas are governed by CPLR Article 23. Attorneys of record can issue them without a court order. Ignoring a valid subpoena can result in contempt of court, fines, or arrest.

In a New York personal injury case, a trial subpoena gets reluctant witnesses into the courtroom. It also puts critical records in front of a jury. The Orlow Firm has tried personal injury cases across all five New York City boroughs for more than 40 years. Securing the right testimony and documents at trial is often what turns a strong claim into a winning one.

A trial subpoena is different from a subpoena used earlier in a case. During pre-trial discovery, attorneys use deposition subpoenas to gather testimony and records before trial. A trial subpoena is aimed at the courtroom itself. It compels a witness or record holder to show up when the case is actually being heard.

Under CPLR § 2301, New York recognizes two statutory forms of subpoena. A subpoena ad testificandum compels testimony. A subpoena duces tecum compels the production of documents or other items. And under CPLR § 2302, attorneys of record, the court clerk, and judges may all issue a subpoena without first getting a separate court order.

The Two Types of Trial Subpoenas Explained

Most trial subpoenas fall into one of two categories, though the two are often combined. Knowing the difference helps clarify what is actually being asked of the person who receives one.

Subpoena Ad Testificandum: A Subpoena for Testimony

A subpoena ad testificandum orders a person to appear and give live oral testimony at trial. No documents are required. The subpoena is asking for what the person knows, in their own words, from the witness stand.

In a personal injury case, this type of subpoena compels testimony from key people. That can mean an eyewitness to a car accident, or a treating physician who can explain how severe and permanent an injury is. It can also mean an accident reconstruction expert, or even the defendant. The witness is summoned to answer questions under oath in front of the judge and jury.

Subpoena Duces Tecum: A Subpoena for Documents and Records

A subpoena duces tecum orders a person or entity to produce documents, records, electronic data, or physical items. The Latin phrase translates roughly to "bring with you," and that is exactly what it requires.

In personal injury litigation, a subpoena duces tecum is used to obtain many kinds of records. Common examples include hospital records, MRI films, employment and wage records, and police accident reports. It can also reach surveillance camera footage from a nearby building or an insurer's claim file. Depending on how it is written, the person served may also be required to testify about those records, or simply to produce them.

There is an important wrinkle with medical records. Say a trial subpoena duces tecum seeks a non-party patient's medical records. It generally requires either the patient's written authorization or a court order before the records can be released. The service rules in CPLR § 2303 alone are not always enough to compel a hospital to hand over a patient's protected medical file. Physician-patient privilege adds a layer of protection that has to be cleared first.

Combined Subpoenas

The two types are frequently combined in a single document. A treating doctor, for example, may be subpoenaed to appear at trial and to bring the patient's complete treatment records. This lets the jury hear the physician explain the injuries while also seeing the underlying documentation.

When Are Trial Subpoenas Used in a New York Personal Injury Case?

Trial subpoenas come into play when a personal injury case actually goes to trial. That typically happens after settlement negotiations have failed to produce a fair resolution. Most injury claims settle. But when they do not, the trial subpoena becomes the tool for assembling the live evidence the jury will hear.

Before that point, attorneys rely on deposition subpoenas during the discovery phase to lock in testimony and gather records. The trial subpoena is the later step. It compels a courtroom appearance once a trial date is set.

A few situations commonly trigger the need for a trial subpoena in New York:

• Eyewitnesses who are unwilling to appear voluntarily
• Medical professionals whose live testimony, not just their written records, is needed to explain injuries to a jury
• Third-party record holders such as hospitals, employers, insurers, or government agencies that have not produced requested documents
• Expert witnesses who must be formally compelled to attend

Timing matters. For document production, CPLR Rule 3120 generally calls for a compliance window of at least 20 days. Trial subpoenas in general must be served within a reasonable time before the trial date. Courts have discretion over what counts as reasonable. Serving a subpoena too close to trial is one of the most common grounds for a challenge.

How Is a Trial Subpoena Issued and Served in New York?

If you have never been through a trial, the process can sound intimidating. But it follows a clear sequence.

First, the attorney prepares the subpoena form. It identifies the person being subpoenaed. It states exactly what is required, whether testimony, documents, or both. And it gives the date and place to appear.

Second, the attorney of record signs it. Under CPLR § 2302, no separate court order is required for most civil subpoenas. The attorney's signature is enough.

Third comes service. Under CPLR § 2303, a subpoena is served the same way a summons is. That usually means in person. The person serving it must be at least 18 years old and not a party to the case, such as a professional process server.

There is a special rule for trial subpoenas directed at a party. Under CPLR § 2303-a, the subpoena may be aimed at a party or someone within a party's control. In that case, it may be served directly on that party's attorney of record. Personal service on the individual is not required.

A witness fee must also be paid or tendered when the subpoena is served. Under CPLR § 8001, the fee is $15 per day of attendance plus $0.23 per mile of round-trip travel from the place of service to the place of attendance. No mileage fee applies for travel that takes place entirely within a city. Finally, an affidavit of service is prepared and kept. It can be filed with the court if compliance later becomes a dispute.

Who Can Be Subpoenaed to Testify at a New York Trial?

Almost anyone with relevant knowledge or relevant records can be subpoenaed. In a personal injury trial, the people most often compelled to appear include:

• Eyewitnesses: bystanders, other drivers, or pedestrians who saw the accident happen
• Medical professionals: treating doctors, surgeons, and physical therapists who can describe the injuries, the prognosis, and future care needs
• Emergency responders: police officers, paramedics, and firefighters whose observations and reports at the scene are primary evidence
• Expert witnesses: accident reconstruction specialists, vocational rehabilitation experts, economists who calculate lost earnings, and life-care planners
• Employers or HR personnel: to establish lost wages and job duties before and after the injury, or to produce employment records
• Third-party record holders: hospitals, clinics, insurance companies, and government agencies
• The plaintiff or the defendant: either party can be compelled to testify

One important limitation: a New York subpoena generally does not reach a witness located outside New York State. Compelling an out-of-state witness usually requires going through the courts of the state where that person is located, under that state's procedures. If a key witness lives elsewhere, raise this with your attorney early.

What Happens If You Ignore a Trial Subpoena in New York?

Ignoring a valid subpoena carries real consequences. Under CPLR § 2308, failing to comply with a judicial subpoena is punishable as contempt of court. A judicial subpoena is one signed by a judge or court clerk.

The statute authorizes a civil penalty of up to $150. It also covers any actual damages caused by the non-compliance. That $150 figure is a specific statutory penalty, not a ceiling on the court's broader contempt powers. A court has additional authority to enforce its orders. The court may also issue a warrant of arrest that directs the sheriff to bring the witness before it. Ongoing refusal to comply, such as continued failure to produce documents, can lead to further sanctions.

If you have received a subpoena and have a legitimate reason you cannot comply, act early. Do not simply skip the date. Contact the issuing attorney as soon as possible. Adjournments and scheduling accommodations are routine, and they are often worked out without involving the court. If the subpoena itself is improper, you can file a motion to quash it, which we discuss in the next section. Illness, a family emergency, or a scheduling conflict are not automatic excuses. But they are far more likely to be accommodated when you communicate in advance.

Can You Challenge a Trial Subpoena in New York?

Yes. A person served with a subpoena can ask the court to cancel or narrow it. You do this by filing a motion to quash or modify under CPLR § 2304.

Common grounds for a challenge include:

• Overly broad or unduly burdensome: the request is out of proportion to its relevance to the case
• Irrelevant: the information sought has no real bearing on the issues being tried
• Privileged: the material is protected by attorney-client privilege, physician-patient privilege (absent proper authorization or waiver), or spousal privilege
• Improper service: the subpoena was not served in the manner CPLR § 2303 requires
• Insufficient notice: it was served too close to the trial date to allow reasonable preparation
• Procedural defect: a required witness fee or other statutory requirement was missing

To challenge a subpoena, you file the motion to quash or modify with the court. Promptness counts. Courts are generally unsympathetic to last-minute challenges raised on the eve of trial. In deciding the motion, the court weighs two things. It looks at the requesting party's genuine need for the testimony or records. And it weighs that against the burden the subpoena places on the person served.

Frequently Asked Questions

What is the difference between a trial subpoena and a deposition subpoena?

A deposition subpoena is a pre-trial discovery tool. It gathers sworn testimony or records before trial, often in a lawyer's office. A trial subpoena compels a person to appear in the courtroom during the trial itself. The two serve different stages of the same case.

Who can issue a trial subpoena in New York?

Under CPLR § 2302, an attorney of record in the case, the court clerk, and a judge may all issue a subpoena. For most civil subpoenas, an attorney of record can do so without getting a separate court order first.

Do I have to comply with a trial subpoena if I receive one?

Yes. Compliance with a valid subpoena is mandatory. Maybe you believe the subpoena is improper, or you have a legitimate reason you cannot comply. If so, contact the issuing attorney right away and, if necessary, file a motion to quash. Do not simply ignore it, because non-compliance can lead to contempt of court.

Will I be reimbursed if I am subpoenaed to testify?

Yes, at least in part. Under CPLR § 8001, a subpoenaed witness is entitled to a fee of $15 per day of attendance plus $0.23 per mile of round-trip travel. No mileage fee applies for travel entirely within a city. This statutory fee does not necessarily cover a witness's full lost income.

Can I be subpoenaed to testify against myself?

In a civil personal injury case, a party can be compelled to testify. The Fifth Amendment privilege against self-incrimination applies differently in civil proceedings than in criminal ones. It is available only in limited circumstances. If you are concerned about self-incrimination, speak with an attorney before responding to the subpoena.

What if I live outside New York: can I still be subpoenaed?

Generally, a New York subpoena issued under the CPLR does not reach a witness located outside New York State. Compelling an out-of-state witness usually requires using the legal procedures of the state where that witness lives. This is a situation worth flagging to your attorney early in the case.

How much advance notice is required before a trial subpoena takes effect?

For document production, CPLR Rule 3120 generally calls for a window of at least 20 days. For testimony, there is no fixed statutory advance-notice period. But a trial subpoena must still be served within a reasonable time before trial. Serving it too late is a common basis for a challenge.

Can a subpoena require my doctor to testify at trial?

Yes. Treating physicians are routinely subpoenaed to testify about a patient's injuries, treatment, and prognosis. When the subpoena also seeks the patient's medical records, the rules tighten. It typically requires the patient's written authorization or a court order before those records can be produced. This is because of physician-patient privilege.
