Most of a California lawsuit is not spent in a courtroom. It is spent in discovery — the formal exchange of documents, written answers, and sworn testimony that occupies the months (often years) between the pleadings and trial. Discovery is where cases are actually built, and where most of the budget goes. Here is how the process works under the Civil Discovery Act, Code of Civil Procedure § 2016.010 et seq., and what business litigants should expect.
What discovery is for
California allows discovery into any matter, not privileged, that is relevant to the subject matter of the action or reasonably calculated to lead to admissible evidence. That standard is broad by design: the system assumes cases settle or get decided better when both sides know the facts. Broad does not mean unlimited — privileges (attorney-client, work product), privacy rights, and trade secret protections all impose real boundaries, and courts can issue protective orders limiting burdensome requests.
The main tools
- Interrogatories (Code of Civil Procedure § 2030.010 et seq.) — written questions answered under oath. Judicial Council form interrogatories cover standard ground; specially prepared interrogatories are custom-drafted and capped at 35 in most cases unless the propounding party justifies more by declaration.
- Requests for production (§ 2031.010 et seq.) — demands for documents, electronically stored information, and inspection of things. In business cases this is the workhorse: contracts, emails, financials, text messages. ESI — email and messaging data — usually drives the cost.
- Requests for admission (§ 2033.010 et seq.) — requests that the other side admit facts or the genuineness of documents, capped at 35 for facts absent a supporting declaration. Underused and powerful: an unjustified denial can support cost-of-proof sanctions later.
- Depositions (§ 2025.010 et seq.) — sworn oral testimony from parties, witnesses, and corporate designees, generally limited to seven hours per witness.
- Third-party subpoenas — banks, customers, former employees, and other non-parties can be compelled to produce records or testify.
The timeline that controls everything
A few dates shape discovery strategy:
- Opening. A defendant may generally start discovery immediately; a plaintiff generally must wait ten days after service of the summons on, or appearance by, the responding party for written discovery, and 20 days after service or appearance for a deposition notice (e.g., Code of Civil Procedure § 2030.020 for interrogatories, § 2025.210 for depositions).
- Response deadlines. Written discovery responses are due 30 days after service, with extensions for mail service. Missing the deadline waives objections — including privilege objections — absent relief from the court, which makes calendaring a matter of substance, not housekeeping.
- Cutoff. Discovery must generally be completed 30 days before trial, and discovery motions heard 15 days before (Code of Civil Procedure § 2024.020). Parties who save key depositions for the end routinely run out of runway.
When the other side will not cooperate
Evasive answers, boilerplate objections, and missing documents are common. The Discovery Act requires the parties to meet and confer in good faith before seeking an order compelling further responses; if that fails, the remedy is a motion to compel. Deadlines matter here too: a motion to compel further responses must generally be filed within 45 days of the insufficient response, or the right is waived. Courts can award monetary sanctions against a party that unsuccessfully resists discovery without substantial justification, and escalating sanctions — evidence, issue, and even terminating sanctions — for serious abuse. Equally important is your own side of the ledger: once litigation is reasonably anticipated, you must preserve relevant documents and data. Suspending auto-delete policies and issuing a litigation hold early prevents spoliation problems that can overshadow the merits.
Keeping discovery proportional
Discovery costs are the reason mid-sized disputes settle, so treat it as a strategic budget decision rather than a checklist. In practice that means sequencing (get the documents before taking the key deposition), using form interrogatories and requests for admission before expensive custom discovery, agreeing early with opposing counsel on ESI search terms and custodians, and asking whether each request will actually move settlement value or trial proof. A focused discovery plan tied to the elements of each claim is one of the first things our business litigation practice builds in a new case — and if you have just been served and discovery is arriving with the complaint, the response clock is already running, so loop in litigation counsel before deadlines start waiving your objections for you.
