California Code of Civil Procedure section 2016.090

Building Your Litigation Arsenal: The Power of Preparedness Under California’s New Discovery Law

Litigation in California is moving fast. As of January 1, 2024, a new rule—California Code of Civil Procedure (CCP) section 2016.090—introduces mandatory early disclosure requirements in many civil lawsuits. This law aims to promote transparency and efficiency, but it also places new responsibilities on litigants. For prepared attorneys and clients, CCP 2016.090 can become a powerful tool in the attorney’s arsenal to streamline litigation and gain a strategic advantage.

This new rule mandates that parties share essential information early in a case when one side formally demands disclosures. Once such a demand is made, the responding party has only 60 days to comply. Required disclosures include names, addresses, and emails of key witnesses likely to possess relevant information, excluding expert witnesses or retained consultants. Additionally, parties must provide copies or descriptions of relevant documents and electronically stored information (ESI) and disclose portions of insurance or indemnification agreements that could satisfy or reimburse a judgment. Certain cases, such as family law, probate, small claims, and unlawful detainer actions, are excluded from these requirements, as are self-represented parties.

When effectively utilized, CCP 2016.090 can significantly streamline discovery by narrowing the issues and reducing surprises, fostering settlements by enabling earlier and more focused negotiations, and strengthening overall case strategy by providing clarity on the opposing side’s evidence. Yet, the rule cuts both ways—demanding disclosures from the other side invites reciprocal demands, and failing to provide complete or timely responses can have serious consequences, including court sanctions such as penalties, restrictions on evidence, or adverse rulings. Additionally, late or incomplete disclosures can damage credibility and weaken your case, leaving you at a strategic disadvantage.

Consider two contrasting approaches to compliance. The reactive client, Client A, delays gathering documents, ignores communications from their attorney, and procrastinates when asked for information. When disclosures are demanded, their attorney struggles to prepare accurate and timely responses, leading to disorganized submissions, increased risk of sanctions, and a weakened case. In contrast, the proactive client, Client B, promptly responds to their attorney, provides relevant documents early, and helps identify witnesses. This engagement enables their attorney to craft thorough, timely responses and focus on strategy rather than damage control, giving the case a significant edge.

To succeed under CCP 2016.090, preparation is key. Start early by identifying witnesses, gathering documents, and reviewing insurance policies as soon as litigation seems likely. Stay organized by keeping evidence labeled and accessible, and be transparent with your attorney by sharing all relevant details promptly. Regular communication ensures disclosures remain accurate and up to date. These practices allow litigants to turn CCP 2016.090 into a strategic tool, rather than a procedural hurdle.

Though still in its infancy and with questions about its enforcement and scope, CCP 2016.090 presents an opportunity for those who prepare early and engage proactively. Whether this rule represents a permanent change in California’s discovery obligations or just a temporary experiment (as it is currently set to sunset on January 1, 2027), one thing is clear: readiness and strategic planning will position litigants for success in California’s evolving legal landscape.
