In a business dispute, the emails often tell the story. Company email, Microsoft Teams messages, internal chats, and shared files can establish what was agreed, who knew what, and whether a later explanation matches the contemporaneous record.
In our practice, we have seen founders, shareholders, and directors lose access to corporate systems when relationships deteriorate. That can turn an already difficult dispute into a costly struggle to obtain the evidence needed to evaluate and prove the case.
The practical lesson: maintain properly authorized corporate access and oversight. Do not leave a potentially adverse insider with unchecked control over the company’s records.
Receiving a production is different from examining the record
When the other side controls the systems, it ordinarily controls the initial searches, collection, and review behind its discovery production. Even a substantial production may leave unanswered questions about what was searched, what was omitted, and whether surrounding communications were included.
An email that appears innocuous by itself may become important when examined alongside other evidence. Earlier messages, attachments, financial records, and subsequent conduct may together reveal a pattern of undisclosed decisions, inconsistent explanations, or coordinated activity bearing directly on the dispute.
The producing side may consider an individual document irrelevant when its significance becomes apparent only through that broader analysis. Incomplete searches and mistaken relevance decisions can therefore obscure evidence without leaving an obvious gap in the documents delivered.
That is why lawful access to a sufficiently complete set of relevant records can be so valuable: counsel can assess the connections independently, rather than depend entirely on an opponent’s search choices.
This does not give either side discretion to cherry-pick. California discovery reaches relevant, nonprivileged information beyond evidence independently admissible at trial. A compliance response must encompass demanded material within the party’s possession, custody, or control to which no objection is made; a claimed inability to comply requires a diligent search and reasonable inquiry. See Code of Civil Procedure § 2017.010, § 2031.220, and § 2031.230.
Discovery can help, but delay has a price
Incomplete productions, unsupported redactions, and delayed responses may require follow-up demands, subpoenas, forensic assistance, or motions to compel. Legitimate privilege and privacy protections remain important; the concern is their misuse or an inadequate search. California permits challenges to specified deficient responses under Code of Civil Procedure § 2031.310.
These disputes consume litigation budgets. Documents produced months or years later may arrive after key strategic decisions or settlement discussions. A party may face pressure to resolve the case before obtaining the record needed to assess its strengths fully.
Maintaining appropriate access before the dispute escalates can avoid having to fight for every piece of the company’s own history.
Authorization matters—and should be documented
Actual, current authorization can be important evidence when access is later characterized as hacking. In Van Buren v. United States (2021), the Supreme Court distinguished an improper purpose from accessing information that was off limits under the federal Computer Fraud and Abuse Act’s “exceeds authorized access” provision.
That distinction does not make an administrator account a blanket exemption from legal duties. The scope and continued validity of permission matter, and California Penal Code § 502 and the federal Stored Communications Act require separate analysis.
Ownership or a corporate title alone does not authorize unrestricted mailbox access, personal copying, or continued access after permission has been revoked. Privilege, privacy, and restrictions on intercepting communications also remain relevant.
Establish safeguards before interests diverge
Companies should consider:
- Keeping accounts, recovery procedures, and administrator succession under appropriate corporate oversight, rather than one insider’s exclusive control.
- Documenting who may access which records, who may change permissions, and how access decisions are approved.
- Maintaining appropriate retention and backup arrangements, and preserving relevant records when litigation becomes reasonably foreseeable.
- Using counsel and qualified technical professionals to preserve and review records when insiders become adverse.
Preservation deserves early attention. In Victor Valley Union High School District v. Superior Court (2023), the court addressed preservation duties once litigation becomes objectively reasonably foreseeable. A later sanctions request cannot reliably recreate missing communications or restore opportunities lost while evidence was unavailable.
Delegating technical administration is often necessary. Delegating unchecked control over the company’s documentary history can be costly. Preserve lawful access, clear authority, and the ability to examine the evidence as a whole—before a disagreement makes those safeguards difficult to establish.
General information, not legal advice. Access rights, preservation obligations, and available remedies depend on the facts and applicable law.
