California family-law discovery can include interrogatories, demands for production, requests for admission, depositions, subpoenas, and inspection of business records. The right tool depends on the precise information gap, the case stage, disclosure history, deadlines, privacy concerns, and the current California rules. Discovery must be relevant and properly served; it is not permission to search accounts or devices without authority.
Start with the question, not the document
Before drafting a request, state the unanswered question in one sentence. Is the issue whether an account exists, how a transfer was funded, what a business earned, or whether a debt was incurred during marriage? Then identify the person or entity likely to have the answer, the date range, and the records that would prove or disprove it.
Begin with the required financial disclosures. Review what was disclosed, make a list of inconsistencies, and preserve the records already available. A targeted request is easier to evaluate than a demand for every document for an unlimited period.
Interrogatories
Form interrogatories use standardized questions for subjects such as income, employment, assets, debts, and claims. Special interrogatories are custom-written questions seeking particular facts. They may ask for the name of a financial institution, the date and purpose of a transfer, a person with knowledge, or the calculation behind a claimed value.
Written questions are useful for identifying facts and custodians, but an answer may be incomplete or disputed. Pair a factual question with a focused document request when the underlying record matters. Watch the response deadline and the limits on the number, format, and scope of questions that apply to the case.
Demands for production
A request for production seeks specified documents, electronically stored information, or tangible things. Examples include bank statements, tax returns, payroll records, loan applications, business ledgers, contracts, retirement statements, and communications concerning a transaction. Describe the category and time period precisely enough that the responding person can understand what is requested.
Overbroad demands create avoidable objections and can obscure the missing record. At the same time, a narrow request should not omit the statements needed to trace a transfer. Consider whether the requested material contains private information and whether a protective order, redaction, or other procedure is necessary.
Requests for admission
Requests for admission ask a party to admit or deny a particular fact, the genuineness of a document, or the application of a fact to the case. They can narrow issues such as ownership, dates, signatures, or the existence of an account. An admission can have significant consequences, so the request and response should be reviewed carefully.
Do not use admissions as a substitute for a broad investigation. A fact that is genuinely disputed should be stated neutrally and supported by the records. The applicable response rules and consequences for failing to respond make calendar control essential.
Depositions
A deposition is sworn questioning outside the courtroom, generally with a written record. It may help when the witness’s explanation needs follow-up, when documents identify new questions, or when credibility and personal knowledge are important. A deposition can be expensive and should have a defined purpose, outline, document set, and plan for unresolved answers.
Business owners, bookkeepers, employers, and other witnesses may have different knowledge. A deposition of a party is not the same as a subpoena to a bank. Counsel should address notice, attendance, privilege, recording, exhibits, and any protective relief before proceeding.
Subpoenas to nonparties
A subpoena may seek records or testimony from a bank, employer, business, accountant, custodian, or other nonparty. Nonparty discovery involves notice, service, privacy, objections, and the custodian’s record procedures. A subpoena is not a shortcut around relevance or a license to obtain every account a person has ever held.
Identify the custodian and records accurately, use the required form and procedure, and allow time for objections. Financial institutions may require a particular records request process. Never impersonate a party or access a private account outside lawful discovery.
If the response is incomplete
Compare the response to the request and the documents already available. Mark each answer as complete, partial, objected to, or requiring clarification. Preserve the original request, proof of service, response, documents, and correspondence. A meet-and-confer may clarify a genuine misunderstanding or narrow an issue.
If the problem remains, a motion to compel or a request for sanctions may be available under the applicable procedure. The court will need the request, response, proof of service, and explanation of why the material is relevant. Do not assume that an objection is waived or that a motion is timely without checking current rules and deadlines.
Financial discovery and privacy
Tax returns, medical information, account numbers, employee data, and business records can contain sensitive information. Use secure storage and disclose only what the procedure requires. Ask about redaction, confidentiality provisions, and protective orders. Do not destroy, alter, forward, or secretly obtain records. Preserve lawful copies and identify how each document was obtained.
Discovery may expose issues involving hidden assets, dissipation, reimbursement, or support. The label is not the proof. A transfer needs context: source, recipient, timing, purpose, authorization, and effect. See what happens when a spouse breaches fiduciary duties and how hidden assets may be found.
Match the tool to the missing fact
California Family Code section 218 gives each spouse access to records about income, assets, and debts, but access to a record is not the same as permission to bypass formal discovery, a third party’s privacy rules, or a protective order. Start with the narrowest lawful path that can answer the question.
| Unanswered question | Often useful first step | What to preserve |
|---|---|---|
| Was a particular account open during the marriage? | Ask for the institution, account type, and statements through a targeted interrogatory or production demand. | Statements, tax forms, and the request/response showing the date range. |
| Where did a large transfer go? | Request the transfer record and an explanation of its source, recipient, purpose, and authorization. | The originating and receiving statements, wire or check detail, and related communications. |
| What did a business earn? | Seek ledgers, tax returns, payroll, general-ledger detail, and records of owner distributions; consider a business-record subpoena. | Native electronic files when available, produced copies, and the identity of the custodian. |
| Does a witness’s explanation hold together? | Use a deposition after reviewing the written responses and exhibits. | The notice, exhibits, transcript or recording, and follow-up issues. |
For example, a request for “all financial documents ever” may invite scope objections without answering whether a $25,000 transfer came from a community account. A request identifying the account, six-month date range, transfer, and related records is easier to evaluate and meet and confer about. A narrower request is not always better: tracing may require statements before and after the transaction.
A sequence for a disputed response
- Compare the response with the request, prior disclosures, and records already available.
- Make a gap list: no answer, incomplete answer, objection, missing attachment, or unexplained inconsistency.
- Send a focused meet-and-confer identifying the request, the defect, and the practical cure. Keep the correspondence professional and calendar any applicable deadline.
- If the issue remains, ask counsel whether a motion to compel a further response, an order for production, or sanctions is available under the current procedure.
- Assemble the request, proof of service, response, correspondence, and relevance explanation before seeking relief.
An objection is not automatically valid or automatically waived. The result can depend on the wording of the request, service, response, privilege, privacy, proportionality, and the relief requested. Do not guess about a response deadline or motion deadline from a different case or an old form.
When a specialist may help
A forensic accountant may help organize tracing or test business and income records; an appraiser may address a defined valuation question; and counsel may need to coordinate with a plan administrator, lender, employer, or records custodian. An expert does not cure missing source documents or turn an assumption into proof. Before spending money, define the question, date range, expected deliverable, and who will pay.
A practical discovery workflow
- Complete and review disclosures.
- Define the missing fact and likely custodian.
- Choose the least burdensome tool that can answer it.
- Set a defensible date range and subject description.
- Check service, response, privacy, and local scheduling rules.
- Calendar the response and meet-and-confer dates.
- Organize responses and identify the next narrow step.
