Discovery in a California divorce often requires information held by someone other than either spouse. Bank statements may be maintained by a financial institution, compensation records by an employer, and business documents by a corporation or other third party. A subpoena provides a formal discovery procedure for obtaining relevant records from nonparties rather than relying exclusively on one spouse to produce them.

Subpoenas Can Obtain Records Directly From Third Parties

California discovery procedures authorize deposition subpoenas directed to nonparty witnesses.

In family law cases, subpoenas are frequently used to obtain business records. These can include bank and credit card statements, employee compensation records, and other financial information relevant to the issues being litigated.

This can be useful when determining income for support, investigating an undisclosed account, tracing funds, examining employment benefits, or analyzing property and debt issues.

A business-records subpoena generally requires the witness or organization to produce the documents described in the subpoena. Depending on the discovery sought, the records may be produced for copying without requiring the witness to appear and give testimony.

A different subpoena procedure can be used when both testimony and documents are required. For example, a nonparty with knowledge of disputed financial transactions may be required to appear for a deposition and bring specified records.

A Subpoena Is Different From a Document Request Served on a Spouse

The identity of the person holding the information determines which discovery procedure may be appropriate.

A Request for Production of Documents is directed to another party in the California family law case. If the requested information is instead held by a nonparty, a subpoena may be necessary to compel production.

Similarly, a party or a representative of a party can generally be required to attend a deposition through a deposition notice. A nonparty witness ordinarily requires a deposition subpoena to compel attendance.

This distinction can become important with closely held businesses. A spouse who is a party may possess some company records personally, while other records may be maintained by a corporation, accountant, payroll provider, bank, or another entity.

Obtaining records directly from a third-party source can also provide information that can be compared with the documents or financial disclosures already produced in the family law case.

Subpoenas Are Subject to Procedural Protections

A subpoena is a formal discovery device and must comply with California procedural requirements.

When a nonparty is required to personally appear for a deposition, the subpoena must be personally served. The timing must provide a reasonable opportunity for the witness to locate required materials and travel to the deposition when an appearance is required.

Other parties to the case must also receive the required notice. When a deposition subpoena is used, a notice of deposition generally must be served on the parties with a copy of the subpoena attached. Different procedures can apply when only business records are requested.

Subpoenaed information is not automatically beyond challenge merely because it may be relevant to a financial dispute. California procedures permit affected people or organizations to seek protection from improper discovery, and courts have authority to address subpoenas that are unreasonable, oppressive, or otherwise subject to a valid objection.

These safeguards can be particularly significant when financial discovery involves confidential or sensitive information.

Conclusion: Subpoenas Can Reach Financial Information Held Outside the Family

A subpoena can be an important California family law discovery tool when relevant information is controlled by a bank, employer, business, or another third party. It can require production of business records and, when appropriate, compel a nonparty witness to appear and testify. Because subpoenas are governed by specific notice, service, and discovery procedures, they serve a different role from document requests directed to a spouse and can provide an independent source of financial evidence in a California divorce.
