California One Deposition Rule: Exceptions and Strategies

California’s one deposition rule governs how many times a party or witness can be deposed in a civil proceeding, shaping trial preparation and strategy. This article explains the rule, its common exceptions, and practical strategies for attorneys navigating depositions in California state court.

What Is California’s One Deposition Rule

In California, the deposition process is designed to gather firsthand testimony before trial. The core concept of the “one deposition rule” is that, in most situations, a party may be limited to a single oral deposition of a particular witness, including other parties. The rule helps prevent undue delay and excessive discovery, while providing pathways to obtain necessary information. Courts recognize that protectable interests and practical needs may justify expanding beyond a single deposition under carefully defined circumstances. Understanding when the rule applies and when it does not is essential for effective case management and settlement planning.

Exceptions To The Rule

• Court Order Or Agreement Of Parties: If the parties jointly request additional depositions or a judge grants permission after showing good cause, extra depositions may be allowed.
• Deposition Of A Party Opponent: In most cases, a party may depose another party, but the rule can be relaxed if the witness has unique information or if prior deposition did not capture critical testimony.
• Deposition By Agreement In Complex Cases: In complex matters with numerous witnesses, parties may stipulate to multiple depositions to avoid forfeiting important evidence.
• Expert Depositions: Experts retained for trial often have separate deposition procedures. Courts generally treat expert depositions as distinct from lay-witness depositions, allowing more than one deposition per expert for fact-finding and opinion disclosure.
• Preserving Evidence Or Addressing Gaps: If new facts emerge or a witness becomes unavailable, additional depositions may be necessary to preserve testimony or fill gaps in the record.
• Retention Of New Information: When a witness provides new or altered information, a second deposition can be warranted to obtain reliable, complete testimony.
• Nonparty Depositions And Subpoenas: Nonparties may be deposed, and the court may permit multiple depositions of the same nonparty under appropriate motions and protective orders.
• Protective Orders And Sanctions Considerations: If a protective order limits deposition scope or duration, courts may allow additional depositions under narrowly tailored terms to balance interests.

Strategies For Litigation Teams

• Early Case Evaluation: Map key witnesses, anticipate needed testimony, and determine which depositions are critical to your theory of the case. This helps decide whether seeking extra depositions is warranted.
• Use Written Discovery To Narrow Depositions: Employ interrogatories and document requests to capture essential facts before scheduling depositions, reducing the need for multiple sessions.
• Strategic Scheduling: Consolidate related witnesses into single sessions when possible. If safety or complexity demands, stagger depositions with a plan for additional sessions under expectations of good cause.
• Prepare For Expert Depositions Separately: Treat expert depositions as distinct events with their own timelines and disclosures. Ensure reports are complete and comply with expert deposition rules.
• Anticipate Objections And Privileges: Build a redaction and privilege log, plan for protective orders, and be ready to address scope disputes that could trigger additional depositions.
• Document The Record: Record key admissions carefully, noting any inconsistencies or newly revealed information that could justify additional depositions under the exceptions.
• Consult Local Rules Early: Local court rules may define the thresholds for good cause, protective orders, and sequencing of depositions; align strategy with these rules.
• Preserve Evidence And Accessibility: Ensure that depositions are accessible for all parties and that transcripts and video records are preserved to support any later motions or appeals.

Practical Steps And Tips

1. Draft A Deposition Plan: Create a schedule listing witnesses, topics, expected duration, and potential need for additional deposition sessions.
2. Request Early Court Guidance: If a deposition scope edge or potential need for multiple sessions arises, seek a conference with the court promptly to avoid later disputes.
3. Limit Scope To Avoid Unnecessary Depositions: Narrow questions to avoid triggering additional sessions unless essential to preserve evidence or clarify critical issues.
4. Prepare For Potential Exceptions: Have a compelling rationale ready for any additional deposition, such as new information or unavailability of a witness.
5. Protect Privilege And Privacy: Use protective orders and privilege logs to manage sensitive topics and prevent unnecessary disclosures.
6. Coordinate With Opposing Counsel: Engage in good-faith discussions to agree on reasonable limits and potential exceptions before filing motions.
7. Budget Time And Resources: Plan for court-ordered extensions or additional sessions, including transcript costs and witness availability.

How Courts Apply The Rule: Common Pitfalls

Court rulings on the one deposition rule vary by jurisdiction within California and by the judge’s discretion. Common pitfalls include attempting to depose the same witness repeatedly without a clear basis, failing to show good cause for extra sessions, and not seeking protective orders when sensitive topics arise. Conversely, properly invoked exceptions—such as new information or expert disclosures—can justify additional depositions. Attorneys should document the necessity for each deposition and maintain a clear record of agreements or court orders to minimize disputes and ensure compliance.

Practical Takeaways

• Know the baseline: Expect that a party generally should not rely on multiple lay-witness depositions without good reason or court permission.
• Plan strategically: Use written discovery to reduce the number of depositions and reserve extra sessions for essential needs or verified exceptions.
• Document everything: Keep thorough notes on why extra depositions are necessary, including witness availability and newly discovered facts.
• Engage early with the court: When in doubt, request guidance from the court to prevent later sanctions or objections.
• Balance efficiency and completeness: Aim to gather reliable testimony while avoiding unnecessary delays or costs.

The California one deposition rule, along with its exceptions, shapes how cases are investigated, prepared, and ultimately trial-ready. By understanding when extra depositions are permissible and employing disciplined strategies, litigants can secure essential testimony while maintaining procedural efficiency and cost-effectiveness.
