The most common objections to requests for production in California are relevance, attorney-client privilege, attorney work product, overbreadth, undue burden, vagueness, privacy, and a set of objections specific to electronically stored information. Every one of them disappears if you fail to serve a written response within 30 days of receiving the request, because that deadline waives all objections, including privilege.1California Legislative Information. California Code of Civil Procedure 2031.300
Serve the Response Within 30 Days or Lose Every Objection
You have 30 days from service of the request to serve a written response. Eviction cases run on a much shorter clock, as little as five days.2California Legislative Information. California Code of Civil Procedure 2031.260 The parties can agree in writing to extend the deadline, or a party can ask the court to change it, but without one of those the original date controls.
Miss it and every objection is waived. That includes attorney-client privilege and work product, protections that would otherwise be nearly impossible to break. Relief is available, but narrow: you have to serve a response that substantially complies with the rules and show the court that the failure resulted from mistake, inadvertence, or excusable neglect.1California Legislative Information. California Code of Civil Procedure 2031.300 Being busy or overworked is not excusable neglect. Calendar the deadline the day the request arrives.
Answer Each Request Separately
You cannot object to a set of requests in a lump. Every individual request needs its own response, and for each one you pick from three choices: agree to produce the documents by a stated date, state that you are unable to comply, or object on legal grounds.3California Legislative Information. California Code of Civil Procedure 2031.210
When only part of a request is objectionable, you cannot refuse the whole thing. You have to comply with the unobjectionable portion (or explain your inability to comply) and separately state your objection to the rest.4California Legislative Information. California Code of Civil Procedure 2031.240 Blanket objections used to stonewall the entire request tend to earn sanctions, not sympathy.
Relevance
California allows discovery of any non-privileged matter relevant to the subject matter of the case, as long as it is admissible or reasonably calculated to lead to admissible evidence.5California Legislative Information. California Code of Civil Procedure 2017.010 Evidence is relevant if it has any tendency to prove or disprove a disputed fact of consequence.6California Legislative Information. California Code Evidence Code 210
That is a broad standard, and courts read it broadly. A relevance objection works when a request reaches for material that has no connection to any claim or defense actually pleaded. When someone in a single-contract dispute demands a decade of unrelated business files, relevance is the objection that pushes back.
Attorney-Client Privilege
The attorney-client privilege shields confidential communications between a client and a lawyer made for the purpose of legal advice. The privilege belongs to the client, who decides whether to assert or waive it.7California Legislative Information. California Code Evidence Code 954
There is a significant exception. The privilege does not cover communications made to enable or aid the client in committing a crime or fraud.8California Legislative Information. California Code Evidence Code 956 In cases alleging financial fraud or corporate wrongdoing, opposing counsel often invokes this crime-fraud exception to try to reach otherwise protected communications.
Attorney Work Product
Work product protection has two levels. An attorney’s mental impressions, conclusions, opinions, and legal theories are absolutely protected and are never discoverable. Other materials an attorney prepared for litigation get qualified protection, and a court can order them produced if withholding them would unfairly prejudice the requesting party’s preparation or result in an injustice.9California Legislative Information. California Code of Civil Procedure 2018.030
The distinction matters in practice. A memo where your lawyer analyzes case strategy is absolute work product. A witness statement your lawyer gathered is only qualified, and the other side may be able to reach it by showing no comparable way to get the same information.
Other Statutory Privileges
Several other privileges can block production. The physician-patient privilege protects confidential communications with a doctor.10California Legislative Information. California Code Evidence Code 994 The psychotherapist-patient privilege covers communications with therapists, psychologists, marriage and family counselors, and comparable mental health professionals.11California Legislative Information. California Code Evidence Code 1014 These privileges frequently clash with the other side’s interest in medical history in personal injury cases.
Trade secrets have their own protection. Information qualifies when it derives economic value from being kept secret and the owner has taken reasonable steps to preserve that secrecy.12California Legislative Information. California Code Civil Code 3426.1 Even when secrets or other sensitive commercial data must be produced, the court can issue a protective order limiting who sees them and how they may be used.13California Legislative Information. California Code of Civil Procedure 2031.060
Overbreadth and Undue Burden
Even relevant material can be off-limits if the request is drafted too broadly or would take unreasonable effort to gather. The responding party addresses these problems by objecting and, when necessary, moving for a protective order, which the court can grant on a showing of good cause.13California Legislative Information. California Code of Civil Procedure 2031.060
Overbreadth applies when a request lacks meaningful limits. “All documents relating to your business operations” with no time frame and no subject-matter cutoff is the textbook example. Requests need to be tailored to actual issues rather than used as fishing expeditions.
Undue burden focuses on cost and effort. Courts weigh what compliance would demand against the likely value of what would be produced, considering the amount in controversy and the resources on both sides. A request that would take $50,000 to answer in a $10,000 case rarely survives that weighing.
Vagueness and Ambiguity
Requests must describe the documents sought with reasonable particularity, meaning you should be able to identify what falls within the request without guessing.14California Legislative Information. California Code of Civil Procedure 2031.030 When key terms are undefined or the request could be read multiple ways, an ambiguity objection is available.
Common triggers are missing time periods, undefined terms, and unclear document categories. A demand for “all communications about the project” leaves open which project, which time frame, and whether internal notes count. The better practice when you receive one is to state the objection and then answer the request as you reasonably interpret it, rather than refuse outright.
Privacy
Privacy is an inalienable right under Article I, Section 1 of the California Constitution.15California Legislative Information. California Constitution Article I Section 1 When a request reaches for sensitive personal information about a party or a third party, financial records, medical files, employment history, personal messages, a privacy objection can block or narrow what has to come out.
Courts balance the intrusion against the requesting party’s need. If they order production anyway, they often impose protective measures like redactions, attorney-eyes-only designations, or confidentiality agreements so the case can move forward without exposing everything.
Objections Specific to Electronically Stored Information
Emails, text messages, databases, and social media raise problems paper never did: volume, retrieval cost, and the risk that metadata will leak privileged material.
Inaccessible ESI and Cost Shifting
When ESI sits on sources that are not reasonably accessible, such as backup tapes, legacy systems, or deleted-file archives, you can seek a protective order by showing that retrieval would impose an undue burden or expense. The burden of proving inaccessibility rests on the party resisting production. If the court decides the information matters enough to justify the effort, it can order production and shift some or all of the cost to the requesting party.13California Legislative Information. California Code of Civil Procedure 2031.060 Even for accessible ESI, the court can limit discovery when the information is available from a more convenient source, the request is duplicative, or the burden outweighs the likely benefit.
Format Disputes
If the request does not specify a format, you produce ESI in the form it is ordinarily kept or in a reasonably usable form. If the request does specify a format and you object, the response must state the format you intend to use instead.16California Legislative Information. California Code of Civil Procedure 2031.280 You are not required to produce the same ESI in more than one format.
Metadata
Electronic files carry metadata, information about authors, edits, and timestamps, that can inadvertently expose privileged material or work product. Responding parties sometimes object to producing metadata at all, or ask for protective measures such as targeted redactions and a full privilege log before any production goes out.
Privilege Objections Require a Privilege Log
Asserting a privilege is not the end of the work. Your response must identify with specificity the documents being withheld, state the grounds clearly, and provide enough factual information for the other side to evaluate the claim.4California Legislative Information. California Code of Civil Procedure 2031.240 That means a privilege log.
A privilege log ordinarily lists each withheld document by date, author, recipient, general subject matter, and the privilege claimed. Enough detail for the court and the other side to test the assertion, without giving up the protected content itself. Thin or vague logs are one of the quickest ways to lose an otherwise sound privilege objection.
The Verification Trap for Corporate Parties
Responses must be signed under oath by the responding party unless the response contains only objections. For entities, an officer or agent verifies on the entity’s behalf. Any response containing an objection must also be signed by the attorney.17California Legislative Information. California Code of Civil Procedure 2031.250
One trap catches corporate parties in particular. If the person verifying for a company is also that company’s attorney, the company waives attorney-client privilege and work product protection as to any later discovery about the sources of information used to prepare the response.17California Legislative Information. California Code of Civil Procedure 2031.250 Corporate defendants almost always have a non-attorney officer sign the verification for that reason.
Meet and Confer Before Anyone Files a Motion
California requires a genuine effort to resolve discovery disputes informally before either side goes to court. Any discovery motion must be accompanied by a meet and confer declaration showing a good-faith attempt at resolution by phone, videoconference, or in person.18California Legislative Information. California Code of Civil Procedure 2016.040 One letter is usually not enough.
Many objections resolve at this stage. The requesting party narrows a request, the responding party agrees to produce with redactions, and the dispute goes away. When it does not, the declaration tells the judge who tried and who did not, which affects who gets sanctioned.
Sanctions for Bad Objections and Bad Motions
If the dispute reaches the court on a motion to compel further responses, sanctions are mandatory against the losing side unless that side acted with substantial justification or sanctions would be unjust.19California Legislative Information. California Code of Civil Procedure 2031.310 Frivolous objections cost money. So does a weak motion to compel. If a party then disobeys an order compelling production, the court can escalate to issue sanctions (treating certain facts as established), evidence sanctions (excluding key evidence), or terminating sanctions (dismissing the claim or entering default).
