Receiving a subpoena is not a request. It is a court-enforceable legal order, and how your business responds in the first 48 hours can determine whether you walk away unscathed or find yourself facing sanctions, spoliation claims, or worse. California business litigation attorneys see this scenario regularly: a business owner receives an unfamiliar legal document, sets it aside, and calls three days later after the response window has already begun to close. This guide tells you exactly what to do from the moment it arrives.

Step 1: Do Not Ignore It

A subpoena issued in California carries the full authority of the court. Ignoring it, or assuming it will resolve itself, can result in monetary sanctions, a finding of contempt, or a default judgment entered against your business. Even if you believe the subpoena is improper, overbroad, or mistargeted, the correct response is immediate action. Silence is never a legal strategy.

California Code of Civil Procedure sections 1985 through 1997 govern subpoenas in civil matters. Violations carry real consequences, and courts have little patience for businesses that treat service of process as optional.

Step 2: Identify What Type of Subpoena You Have Received

Not all subpoenas require the same response, and misidentifying the type is one of the most common early mistakes. California businesses typically encounter four categories:

• A Subpoena for Documents (SDT) requires your business to produce records, files, electronically stored information, or other tangible materials by a specified date.
• A Deposition Subpoena compels a witness or records custodian to appear and testify under oath, with or without documents.
• A Trial Subpoena requires appearance at a court proceeding or evidentiary hearing on a specific date.
• A Third-Party Records Subpoena is issued to your business seeking records about another party, such as a customer, employee, vendor, or business partner.

Each type carries distinct deadlines, objection windows, and production obligations. Identifying the type correctly on day one shapes everything that follows.

Step 3: Immediately Preserve All Relevant Documents

The moment your business receives a subpoena, or reasonably anticipates litigation, a legal duty to preserve evidence is triggered. This obligation is called a litigation hold, and it is not optional. Failure to preserve relevant documents can result in court sanctions, adverse inference jury instructions, or a finding of spoliation, which is the destruction or alteration of evidence.

A litigation hold notice should go out internally the same day the subpoena arrives. It should cover every location where potentially relevant information might exist, including:

Emails across all company accounts, including sent items and deleted folders. Text messages, voicemails, and direct messages. Internal communications through platforms such as Slack, Microsoft Teams, or Google Chat. Accounting software, billing records, and financial data. Contracts, proposals, and business correspondence. Cloud storage platforms including Google Drive, Dropbox, and OneDrive. Personal devices used by employees for any business purpose.

Do not wait for outside counsel to initiate this step. By the time an attorney is retained and onboarded, documents may already be gone.

Step 4: Understand Your Right to Object

Receiving a subpoena does not mean your business must comply with every element of what is requested. California law provides meaningful tools for challenging subpoenas that are overbroad, unduly burdensome, legally defective, or that seek protected information.

Written objections must typically be served on the issuing party before your response deadline. These objections can challenge scope, relevance, and proportionality without requiring a court filing.

A motion to quash asks the court to invalidate the subpoena entirely. A motion for a protective order asks the court to limit what must be produced and under what conditions.

Privacy objections carry particular weight in California. The state Constitution recognizes privacy as a fundamental right, and courts have applied this protection to business records in appropriate circumstances.

Trade secret protection is available where compliance would require disclosure of proprietary formulas, client lists, business strategies, or other confidential commercial information.

Overbreadth and undue burden challenges are available when the scope of the request is disproportionate to the legitimate needs of the litigation.

All of these rights can be waived if not raised before the response deadline. This is why early review by experienced California business litigation counsel is essential, not optional.

Step 5: Recognize What the Subpoena May Actually Signal

Business owners sometimes make the mistake of treating a subpoena as an administrative nuisance rather than as a legal signal worth decoding. The document itself tells you something beyond its face value.

A subpoena to your business may mean you are a witness with relevant information about a dispute between other parties. It may mean you are a target and that a lawsuit or regulatory action is being built around your conduct. It may mean litigation is imminent and that opposing counsel is gathering evidence before filing. It may mean a business relationship is fracturing and a former partner, vendor, or employee is preparing a claim. It may mean a government agency or regulatory body has opened an investigation and is using the subpoena as an early-stage discovery tool.

If the situation is unclear, assume the more serious interpretation until your attorney tells you otherwise. The cost of over-preparing is low. The cost of under-preparing can be severe.

What Not to Do After Receiving a Subpoena

The errors businesses make in the hours and days following receipt of a subpoena are frequently more damaging than the underlying legal matter. Experience in California business litigation reveals the same mistakes appearing repeatedly:

• Do not delete, move, or alter any documents, even as part of a routine retention schedule. Once a litigation hold obligation exists, normal document destruction can become spoliation.
• Do not coach employees on what to say or not say. This creates independent legal exposure and can be characterized as obstruction.
• Do not contact the opposing party or their attorney without counsel present. Anything said in those conversations can be used against your business.
• Do not produce documents informally or without a legal review. Informal production can waive attorney-client privilege, work product protection, or other critical shields.
• Do not assume your commercial insurance policy will manage the response automatically. Most policies require prompt notice of claims or legal proceedings, and many have significant coverage exclusions for litigation-related costs.
• Do not circulate information about the subpoena broadly within the company. Communications about litigation strategy should be limited to those with a direct need to know and should flow through counsel to preserve privilege.

Key Takeaways for California Business Owners

A subpoena is a court-enforceable legal order that requires a timely and strategic response. The type of subpoena you receive determines your deadlines and your options. A litigation hold must be issued immediately to protect documents across every platform and device. Objection rights exist but are waived if not exercised before the response deadline. The subpoena itself may signal a larger legal threat than its face value suggests. The most common and costly mistakes involve document deletion, informal production, and delayed engagement with counsel.

If your California business has received a subpoena, the window for the most important decisions is measured in hours, not weeks.
