1. Receiving a Subpoena Does Not Mean You Have Been Charged
A subpoena demands evidence or testimony; it does not itself file criminal charges. You may be a witness, or investigators may be examining your conduct. In a federal investigation, prosecutors may call someone a “subject” when the person’s conduct is within the investigation and a “target” when substantial evidence links the person to a crime and the prosecutor views the person as a potential defendant.
Identify the Recipient and the Investigating Office
Confirm whether the subpoena is directed to you, a business, a bank, or another record holder. If a bank receives it, the bank ordinarily has the response obligation. A notice about records sought from a third party is different from a subpoena requiring your own appearance or documents.
A bank’s internal fraud review is also separate from a law-enforcement investigation. An attorney familiar with white collar investigations can help identify the issuing authority and your role.
2. Confirm What the Subpoena Requires and When
Read the subpoena together with every attachment. A records demand may require documents, testimony, or both, and producing records does not necessarily excuse an appearance.
| Item | What to confirm |
|---|---|
| Issuer and recipient | Court, grand jury, agency, person, or company |
| Appearance | Date, time, place, and who must attend |
| Records | Accounts, transactions, date range, and format |
| Submission | Return date and delivery instructions |
Federal and California Procedures Differ
Federal Rule of Criminal Procedure 17(c) permits a court, on a prompt motion, to quash or modify a records subpoena if compliance would be unreasonable or oppressive.
California criminal subpoenas follow state procedures, including Penal Code § 1326. Do not assume that a federal production rule applies in California state court.
Penal Code § 484e addresses different conduct involving access cards and account information. For example, subdivision (d) covers acquiring or retaining another person's validly issued access-card account information without consent and with intent to use it fraudulently.
Where personal identifying information is involved, Penal Code § 530.5 may present a separate issue. Subdivision (a) addresses willfully obtaining another person's identifying information and using it for an unlawful purpose without that person's consent.
The differences matter. Possessing account information, processing a transaction, and using another person's identity are not the same allegation, and each statute has its own elements.
Request Any Change before the Deadline
An attorney may ask the issuing office to change timing or scope, but requesting an extension does not itself change the response date. Confirm any agreement or court order before relying on it. Keep copies of the production, proof of delivery, and written changes.
3. Review Privilege and Self-Incrimination before Responding

Oral testimony, personal records, and business records can raise different Fifth Amendment and privilege issues. Review the specific demand before answering questions or turning over files.
Existing Records Are Not Automatically Protected
The Fifth Amendment can protect a person from compelled testimonial answers that may be incriminating. It does not create a blanket right to withhold existing records.
In some circumstances, producing personal documents can itself communicate facts about their existence, possession, or authenticity. That issue requires separate analysis. A privilege claim also does not automatically excuse a required appearance.
Attorney-Client Privilege Does Not Cover Ordinary Evidence
Attorney-client privilege generally protects confidential communications made for legal advice. Giving an attorney an existing receipt, statement, or message does not make the underlying document privileged merely because the lawyer now has it.
Separate attorney communications from ordinary transaction records for review, but do not delete or alter files.
California Immunity Requires a Specific Court Process
In a California felony proceeding or felony grand jury investigation, Penal Code § 1324 allows a prosecutor to ask a court to compel testimony or evidence after a witness invokes the privilege against self-incrimination. If the court issues the required order and the witness complies, the compelled information and information directly or indirectly derived from it generally may not be used against that witness in a criminal case, subject to the statute’s terms.
Testifying under subpoena does not automatically create immunity.
4. Preserve Records That Explain the Transactions
A credit card fraud investigation may turn on authorization, identity, and intent. Preserve records that show who made or approved a transaction, what limits applied, and what happened afterward.
Keep the Full Transaction Context
Useful records may include:
- Statements and receipts showing amounts, dates, refunds, and chargebacks.
- Messages showing permission, spending limits, repayment terms, or disputes.
- Login, device, delivery, and account-access records that may help identify the user.
- Complete message threads when surrounding context affects meaning.
Permission for one purchase does not necessarily establish permission for later charges. A shared address or device also does not, by itself, establish who made a transaction.
Do not delete files, alter dates, edit messages, or ask another person to change an account of what happened.
5. What Happens after You Respond to the Subpoena
A response may be one step in a longer investigation. Investigators may compare records with bank data, interview witnesses, seek more evidence, file charges, or decide not to prosecute. Producing records does not guarantee that the investigation will close.
The Response Date Is Not a Charging Deadline
The subpoena return date tells you when a response is required. It does not establish when prosecutors must make a charging decision. Consumer billing-dispute deadlines are also separate from criminal charging rules.
Silence from investigators does not necessarily mean that a federal or California investigation has ended.
