Understanding non-party subpoenas in Massachusetts Probate and Family court

It can be helpful in a family law case to have someone who isn’t part of your case give information or documents. You can ask them to give this information by using a “subpoena.” A subpoena (pronounced supp-pee-na) is a letter that asks someone who isn't directly involved in your court case to testify under oath about a specific topic. It can also ask them for certain documents.

The person who gets this subpoena is called a "non-party witness."

What kinds of subpoenas are there?

There are 3 different types of subpoenas.

Testimonial subpoena

This tells a non-party witness that they have to testify at a specific time and place during a hearing or trial.

Deposition subpoena

This tells a non-party witness that they have to go to a deposition. This is like an interview under oath. It might also ask for documents or information related to the case. This could include electronically stored information, like texts or emails.

Document-only subpoena

This tells a non-party witness that they have to send documents. They don’t need to go to a deposition or court. You also use a document-only subpoena when you want to get records from a business or agency.

Note

It is a good idea to talk to a witness before you send them a subpoena. Tell them the questions you plan to ask them at the hearing or deposition.
