During a California divorce, spouses sometimes need more information than financial disclosures, written questions, or document requests can provide. A deposition is a formal discovery procedure that allows a party or another witness to be questioned under oath before trial. Depositions can be useful when a case involves disputed finances, property, support, or other facts that require detailed questioning.

How Does a Deposition Work?

An oral deposition is an examination conducted under oath and transcribed by a court reporter. The person answering the questions is called the deponent.

A deposition can be taken of a spouse or another person who has information relevant to the case. When a party is being deposed, a formal Notice of Deposition is generally used to require attendance. The notice can also request that the person bring specified documents, electronically stored information, or other relevant materials.

When the person being questioned is not a party to the divorce, a deposition subpoena may be necessary. Depending on what information is needed, the subpoena can require the witness to appear, produce documents, or both.

Because testimony is given under oath, a deposition is different from an informal conversation or exchange of information between the spouses.

Why Might a Deposition Be Useful?

Depositions allow detailed follow-up questioning that may be difficult to accomplish through written discovery.

For example, if a spouse owns a business and their income is disputed, deposition questions may address business revenue, expenses, compensation, financial records, and other facts relevant to support. Questions can also address property transactions, separate property claims, or other contested financial matters.

A deposition may also help clarify information already obtained through financial disclosures or document requests. If bank records show an unfamiliar transaction, for example, questioning may help establish what occurred and why.

Depositions can also help prepare a case for trial. Testimony given under oath creates a record that may later become important if a witness provides materially different testimony.

California generally limits a party to one deposition of a particular person unless the parties agree otherwise or the court permits another deposition. That makes it important to consider which subjects should be covered.

Are Depositions Used in Every Family Law Case?

No. Formal discovery can require significant time and expense, so the appropriate method depends on the issues involved.

Some California divorces can be resolved using mandatory financial disclosures, informal exchanges, interrogatories, and document requests without taking depositions. In more complicated cases, however, a deposition may provide information that cannot be obtained as effectively through written questions.

Timing also matters. California discovery procedures establish rules concerning when deposition notices may be served and how much notice must be provided.

Special timing problems can arise when a deposition is needed before a hearing on temporary orders. A hearing concerning temporary child support or spousal support may occur relatively early in the case, leaving less time to complete ordinary discovery. In appropriate circumstances, the parties may agree—or a party may ask the court—to shorten applicable discovery timing.

Conclusion: Depositions Can Help Clarify Important Disputed Facts

A deposition is a formal opportunity to question a spouse or another witness under oath during a California family law case. It can be particularly useful when financial information, business income, property transactions, or other important facts require detailed examination. Although depositions are not necessary in every divorce, they can provide valuable evidence and help define the issues that may need to be resolved through settlement or trial.
