Serving a Subpoena for Records on a Non-Party Custodian in Tennessee: An Attorney’s Guide
Short answer: To get documents from someone who is not a party to a Tennessee lawsuit, such as a hospital, bank, employer, phone carrier, or business, an attorney issues a subpoena for production under Rule 45 of the Tennessee Rules of Civil Procedure and has it properly served on the records custodian or the entity's registered agent. Service has to be done correctly, with the required notices to the other parties, and some categories of records come with extra legal requirements: medical records involve HIPAA "satisfactory assurance" rules, financial records involve Tennessee's financial privacy statute, and out-of-state custodians usually require the subpoena to be domesticated in the custodian's state. A professional process server makes sure the subpoena reaches the right person, documents exactly how and when, and gives counsel a clean affidavit if the custodian later fails to comply.

Key takeaways
Non-party records are obtained by subpoena under Tenn. R. Civ. P. 45, not by ordinary discovery requests, which bind only parties.
Correct service matters as much as correct drafting. Serving the wrong person at a large organization is one of the most common reasons subpoenas are ignored.
Medical, financial, telecommunications, and employment records each carry additional privacy rules. Plan for notice periods and protective orders.
Custodians outside Tennessee generally require domestication under their own state's procedures, such as the Uniform Interstate Depositions and Discovery Act where adopted.
A detailed affidavit of service, including the custodian's name and title, is what supports a motion to compel or contempt if the records never arrive.
What is a subpoena duces tecum?
A subpoena duces tecum is a subpoena that commands a person or organization to produce documents, electronically stored information, or tangible things. In Tennessee civil cases, Rule 45 governs subpoenas, including subpoenas that require production without requiring the custodian to appear and testify. Because non-parties are not bound by interrogatories or requests for production, the subpoena is the primary tool for obtaining their records before trial.
Who is the "records custodian" and who should be served?
The records custodian is the person responsible for maintaining and producing the requested records, such as a hospital's health information management department, a bank's legal or subpoena compliance unit, an employer's HR department, or a small business's owner. For organizations, service on the entity's registered agent is often appropriate, and many large organizations designate a centralized subpoena processing office. The mistakes that lead to delay are predictable:
Leaving the subpoena with a receptionist or branch employee with no authority to accept it.
Serving a local branch or clinic when the organization requires service at a centralized compliance office or registered agent.
Naming the wrong legal entity, such as a brand name instead of the company that actually holds the records.
Failing to allow a reasonable time for compliance or failing to include required notices.
Before service, a good process server or investigator confirms the correct legal entity through Secretary of State filings, identifies the registered agent and any designated subpoena office, and, where the organization publishes subpoena instructions, follows them.
How is a non-party subpoena served in Tennessee?
A subpoena in a Tennessee civil case can generally be served by a sheriff or deputy or by a non-party adult, which is why attorneys commonly use professional process servers. The server delivers the subpoena to the custodian or authorized agent and completes a return or affidavit stating the date, time, place, manner of service, and the identity of the person served. For records custodians, the affidavit should also capture the person's title and confirmation that they accepted on behalf of the entity.
Counsel should also remember obligations to the other parties. Parties are generally entitled to notice of subpoenas for production so they can object or seek protection, and courts expect copies of produced documents to be made available to other parties. The process server's job is service on the custodian. The attorney handles notice to parties.
What extra rules apply to medical records?
Under HIPAA, a covered health care provider may disclose protected health information in response to a subpoena that is not accompanied by a court order only if it receives "satisfactory assurance" that the patient was notified and had a chance to object, or that the requesting party sought a qualified protective order. In practice, hospitals and clinics often reject subpoenas that arrive without the right documentation, without a signed patient authorization, or without a court order. Tennessee also has statutory procedures allowing hospitals to produce certified copies with an affidavit rather than sending a custodian to court. Attorneys who anticipate those requirements, and process servers who deliver the full packet to the right office, avoid weeks of back-and-forth.
What about bank and financial records?
Tennessee's Financial Records Privacy Act restricts when financial institutions may disclose customer records and generally requires that the customer receive notice of the subpoena before the institution produces records, along with a waiting period that allows the customer to object. Subpoenas for bank records should be prepared with those requirements in mind and served on the institution's designated legal processing office. Federal rules can also apply to certain institutions and records.
What about phone carriers, employers, and digital platforms?
Phone carriers generally produce subscriber and billing records in response to valid civil process, but federal law significantly limits disclosure of communication contents. Carriers maintain legal compliance centers with specific service instructions, and retention periods for some data are short.
Employers can be subpoenaed for personnel, payroll, attendance, and similar records. Small employers may need extra time; large employers usually route subpoenas through HR or legal.
Social media and technology companies are often located outside Tennessee and are restricted by federal law in what content they can disclose to civil litigants. Basic subscriber information may be available through properly domesticated process, while content usually must come from the account holder through party discovery.
How do you subpoena records from a custodian outside Tennessee?
A Tennessee court's subpoena does not automatically compel a custodian in another state. Most states have adopted the Uniform Interstate Depositions and Discovery Act (UIDDA), which allows a party to present the out-of-state subpoena to a clerk in the custodian's state, which then issues a local subpoena. Tennessee has its own procedures for domesticating foreign subpoenas served on custodians here. Some states use different procedures. Delator Group coordinates service with trusted partners when records sit outside Tennessee, while our Tennessee team handles in-state custodians across all 95 counties.
What happens if the custodian ignores the subpoena?
A non-party who fails without adequate excuse to obey a properly served subpoena may be held in contempt, and the issuing party can move to compel compliance. Courts look first at whether service was proper. That is where a detailed affidavit of service, naming the person served, their title, and the circumstances, becomes the foundation of the motion. Before filing, many attorneys have the process server or an investigator follow up with the custodian to confirm receipt and timeline, which resolves most delays without court involvement.
Frequently asked questions
Can a private process server serve a subpoena in Tennessee?
Yes. Subpoenas in Tennessee civil cases are commonly served by non-party adult process servers as well as sheriffs and deputies. Professional servers provide faster service and more detailed affidavits.
How long does a records custodian have to comply?
The subpoena must allow a reasonable time for compliance. Many attorneys allow at least the time contemplated by the rules and the custodian's own policies, and longer for medical or financial records that carry notice periods.
Do I have to serve the subpoena on the registered agent?
Not always, but serving the registered agent or the organization's designated subpoena office is usually the safest way to ensure an entity is properly served. Serving a front-desk employee at a branch office is a common reason for non-compliance.
Can a subpoena get someone's text messages from the phone company?
Generally not the content. Federal law restricts carriers from disclosing the content of communications in civil cases. Subscriber and billing records may be obtainable, while message content usually must come from a party's own device through discovery or forensic collection.
What should the affidavit of service include?
The case caption, the date, time, and address of service, the manner of service, the name and title of the person who accepted, the server's identity, and a description of the documents served.
Does Delator Group serve subpoenas statewide?
