Grand Jury Subpoenas vs Trial Subpoenas: Key Differences

March 21, 2024

Grand Jury Subpoenas vs Trial Subpoenas: Key Differences

Grand jury subpoenas and trial subpoenas are two types of subpoenas used in the legal system, but they serve different purposes and have some key differences.

What is a Grand Jury Subpoena?

A grand jury subpoena is issued by a federal grand jury during a criminal investigation. The grand jury uses subpoenas to gather evidence and determine if there is probable cause to indict a suspect[1].

There are two main types of grand jury subpoenas:

  • Subpoena ad testificandum – requires someone to testify before the grand jury
  • Subpoena duces tecum – requires the production of documents or records

Grand jury subpoenas are broad in scope – they can request testimony on any matter relevant to the investigation. There is no requirement to show probable cause. The prosecutor issues grand jury subpoenas without judicial oversight[2].

Once served, compliance is mandatory. However, grounds may exist to challenge the subpoena, such as privilege, undue burden, or improper service[3].

What is a Trial Subpoena?

A trial subpoena is used during litigation to compel witness testimony or document production. Trial subpoenas are issued by the court or attorneys involved in the case[4].

There are also two main types of trial subpoenas:

  • Subpoena ad testificandum – secures witness testimony at a trial, hearing or deposition
  • Subpoena duces tecum – compels document or record production

Trial subpoenas are more limited in scope than grand jury subpoenas. They can only request evidence relevant to the specific case issues[4]. Parties must also follow discovery rules and protocols.

Key Differences

There are some important differences between grand jury and trial subpoenas:

  • Purpose – Grand jury subpoenas are investigative tools while trial subpoenas are used for litigation.
  • Scope – Grand jury subpoenas have a broader scope and parties can’t object on relevance grounds. Trial subpoenas are narrower.
  • Issuing Authority – Prosecutors issue grand jury subpoenas while courts or litigants issue trial subpoenas[5].
  • Challenging – It’s harder to quash a grand jury subpoena. Parties have more grounds to challenge trial subpoenas.
  • Secrecy – Grand jury proceedings are secret so subpoena details may not be disclosed. Trial subpoenas are public.
  • Service – Grand jury subpoenas only need to be served on the recipient. Trial subpoenas require service on all parties.
  • Compliance – Failing to comply with a grand jury subpoena can result in contempt. Non-compliance with a trial subpoena may lead to sanctions.
  • Records – Documents produced under a grand jury subpoena remain secret. Trial subpoenaed records enter the public court record.

Practical Implications

The differences between grand jury and trial subpoenas have important practical implications:

  • Recipients of grand jury subpoenas have less ability to challenge them and must comply or risk contempt charges.
  • Parties served with trial subpoenas can raise objections and work to limit scope through the discovery process.
  • Witnesses who testify before a grand jury may not disclose details while trial testimony is public.
  • Entities responding to grand jury subpoenas must take care not to waive privilege and maintain confidentiality.
  • Attorneys dealing with trial subpoenas should follow rules of service and court protocols.


While grand jury and trial subpoenas compel evidence production, they serve distinct legal functions. Understanding the key differences in scope, secrecy, service requirements and compliance is important for anyone involved in the legal process. Parties served with subpoenas should consult counsel to ensure they respond appropriately and protect their rights.

Grand Jury Subpoenas vs Trial Subpoenas: What’s the Difference?

Getting slapped with a subpoena is never fun – whether it’s for a grand jury or an actual trial. But it‘s important to understand the key differences between these two types of subpoenas, and how they can impact your case.Let’s break it down.

What is a Grand Jury Subpoena?

A grand jury subpoena is basically a demand for testimony or evidence related to a criminal investigation. It’s issued by a grand jury, which is a group of citizens who determine if there’s enough evidence to indict someone for a crime.These subpoenas can be a real pain; they require you to show up and testify under oath, or hand over documents/records that could potentially be used against you (or someone else) in court. And get this – you can’t just ignore a grand jury subpoena like this Reddit thread discusses. Failure to comply is considered contempt of court, which can land you in jail. Yikes.But here‘s the kicker – with a grand jury subpoena, you don’t get the same constitutional protections as you would in an actual trial. The prosecutors running the show get to call the shots, and there‘s no judge or defense attorney to object to unfair questions or keep them in check. It‘s basically an inquisition.

That’s why it’s crucial to have an experienced criminal defense lawyer by your side if you get hit with one of these subpoenas. They can advise you on how to navigate the situation, prepare you for questioning, and make sure your rights aren‘t violated.

What About a Trial Subpoena?

Now let‘s talk trial subpoenas. These bad boys get issued once charges have actually been filed and a case is headed to trial. The subpoena orders you to show up and testify as a witness, or provide certain documents/evidence.Unlike grand jury subpoenas, trial subpoenas come with way more constitutional protections. You‘ve got the right to have a lawyer present who can object to improper questioning. The judge acts as a neutral referee, making sure everything is fair and above board.But here‘s where it gets tricky – if you defy a trial subpoena, you could be held in contempt of court and potentially arrestedAs this Quora thread discusses, the consequences can be pretty severe.That’s why it’s so important to take these subpoenas seriously and have proper legal representation. Your lawyer can file motions to quash or modify the subpoena if it’s unreasonable or overly broad. They‘ll prep you for testimony and make sure you don’t accidentally incriminate yourself or others.

Key Differences at a Glance

Still feeling a bit confused? Let’s sum up the main differences:Grand Jury Subpoena:

  • Issued during investigation phase before charges filed
  • No judge or defense lawyer present
  • Fewer constitutional protections
  • But failure to comply is contempt of court

Trial Subpoena:

  • Issued after charges filed for upcoming trial
  • Constitutional protections in place
  • Judge oversees proceedings
  • But defying subpoena can lead to arrest

See the pattern here? Grand jury subpoenas are more of a legal gray area with less oversight. Trial subpoenas have more checks and balances, but the stakes are higher if you don’t comply.No matter which one you’re dealing with, having a skilled criminal defense attorney is non-negotiable. Don‘t try to go it alone.

Why You Need a Lawyer for Subpoenas

Look, I get it – lawyers are expensive. And maybe you‘re thinking, “How bad could it be? I’ll just go in, answer some questions, and be on my way.”But here‘s the hard truth: trying to handle a subpoena without legal representation is like bringing a knife to a gunfight. You‘re outmatched, outgunned, and you‘re putting yourself at serious risk – both legally and financially.Think about it this way; the prosecutors and investigators on the other side of that subpoena? Their sole job is to build a case against you or whomever they‘re investigating. **They’re not interested in hearing your side of the story – they want ammunition to take you down.**With a skilled criminal defense lawyer in your corner, you gain a crucial advantage. We have relationships and insight into how these prosecutors and investigators operate. We know their strategies, their tactics, and we can prepare you properly.We make sure you don’t accidentally incriminate yourself or reveal sensitive information that could derail your case (or your life!) down the line. We object to improper questioning, and we put up a legal shield to protect your rights.But it goes beyond just showing up for questioning. We can file motions to quash or modify overly broad, burdensome subpoenas. We can negotiate terms that don’t violate your constitutional protections. And if you do end up having to testify, we make sure you’re prepared and protected every step of the way.Don’t buy into the myth that if you’ve got nothing to hide, you’ve got nothing to worry about. Even the most well-meaning, honest person can get tripped up by a prosecutor‘s line of questioning and end up incriminating themselves accidentally. It happens all the time.At the end of the day, that subpoena is a legal threat – and you need to treat it as such. Having the right criminal lawyer in your corner isn’t just smart… it’s absolutely essential to safeguarding your future.

What to Do If You Get a Subpoena

So let‘s say you just got slapped with a subpoena for a grand jury or an upcoming trial. Your stomach drops, your palms get sweaty, and you’re feeling overwhelmed with questions:“What does this mean? Do I actually have to go? What if I just ignore it? Will I get in trouble?”Take a deep breath, because we’ve got your back. Here’s exactly what you need to do if you find yourself in this situation:

  1. Don’t panic, but don’t ignore it either. Subpoenas are legally binding orders. Ignoring one can lead to contempt charges, fines, and even jail time. Not a fun situation.
  2. Read the subpoena carefully. It will outline what’s being requested of you – testimony, documents, records, etc. Make sure you understand the scope of what they’re asking for.
  3. Don’t try to go it alone. This is not the time for DIY legal advice. Hire an experienced criminal defense attorney immediately. Like, today. We cannot stress this enough.
  4. Don’t speak to anyone about the case. Don’t talk to prosecutors, investigators, or the other parties involved. Anything you say can potentially be used against you later.
  5. Let your lawyer handle it. Once you’ve hired counsel, they will take over all communication and legal maneuvering regarding the subpoena. We know how to protect your rights.
  6. Follow your lawyer’s instructions to a T. We’ll let you know if/when you need to testify or provide evidence. We’ll prep you for any questioning. Listen to our advice.

But knowing the right steps to take, and having a powerhouse legal team like Spodek Law Group in your corner, can make all the difference.We’ve handled countless subpoena cases in New York and around the country. We know the system inside and out, and we’ll fight tooth and nail to protect you. So don’t go it alone – get us on your side ASAP.

Common Subpoena Defenses

Now you know how crucial it is to have a skilled lawyer for any subpoena situation. But what kinds of legal strategies can they actually use to protect you?Here are some of the most common defenses and motions we utilize:Motion to Quash or Modify the SubpoenaThis is probably going to be our first move – filing a motion asking the court to throw out (quash) or modify an unreasonable, overly broad subpoena.Maybe the subpoena is requesting privileged information that should be protected. Or it’s asking for an unreasonable amount of documents that would be extremely burdensome to produce.Whatever the issue, we’ll make a strong legal argument for why that subpoena needs to be quashed or scaled back. This Findlaw article has a good overview of these types of motions.Invoking Constitutional PrivilegesDepending on the situation, we may advise invoking certain constitutional privileges to avoid testifying or providing incriminating evidence.The two biggies are the 5th Amendment right against self-incrimination, and the 6th Amendment right to counsel. We can argue that complying with the subpoena would violate these core constitutional protections.Lack of RelevanceAnother common defense is arguing that the requested testimony or evidence simply isn’t relevant to the underlying case. If we can show that what they’re asking for has no bearing on the issues at hand, the subpoena doesn‘t hold water.Undue BurdenIf producing the requested documents or records would create an unreasonable, overly burdensome situation for you or your business, we can file a motion arguing undue burden. The court has to balance the need for evidence against the strain on the subpoena recipient.At the end of the day, we’ll analyze every possible legal angle and argument to either quash the subpoena entirely or scale it back as much as possible. Our goal is to protect your rights and interests.
