No, law firms are not required to encrypt every client email, but New Jersey lawyers must use reasonable safeguards to protect confidential information under RPC 1.6(c). That means encryption or a secure client portal is expected whenever an email contains sensitive data that could harm a client if exposed. This standard was clarified by the New Jersey Advisory Committee on Professional Ethics in Opinion 701 (2006).
What “Reasonable Safeguards” Mean Under RPC 1.6
RPC 1.6(c) requires lawyers to make “reasonable efforts to prevent the inadvertent or unauthorized disclosure” of client information. The rule doesn’t prescribe a specific technology—it requires sound judgment. If you’re sending a routine scheduling note, encryption may not be needed. But if you’re sharing settlement discussions, contracts, or financial data, it likely is.
- Routine communications: Scheduling, meeting reminders, or procedural updates — encryption optional.
- Confidential matters: Settlement terms, discovery files, medical or financial records — encryption recommended or required.
- Highly sensitive data: Anything that could cause harm or disadvantage if leaked — encryption expected.
Examples of When Encryption Is Required
Encryption becomes mandatory whenever the information could expose the client or violate professional confidentiality. Common examples include:
- Transmitting discovery materials or confidential evidence.
- Sharing settlement proposals or negotiation details.
- Exchanging Social Security numbers, financial statements, or medical reports.
- Communicating over public Wi-Fi or unsecured devices.
Best Practices for Law Firms
Even when not strictly required, implementing encryption as a standard practice shows due diligence and enhances client trust. New Jersey firms can meet compliance standards with a few core measures:
- Use built-in encryption tools in Microsoft 365 or Google Workspace for sensitive messages.
- Adopt a secure client portal for sharing large files or confidential documents.
- Train staff regularly on email security and recognizing phishing attempts.
- Establish a written IT policy defining when encryption must be used.
Beyond Encryption: Authenticating Your Firm’s Email with DMARC
Encryption protects what’s inside an email, but it doesn’t prevent impersonation or spoofing. That’s where DMARC (Domain-based Message Authentication, Reporting, and Conformance) comes in. DMARC ensures only authorized servers can send messages using your firm’s domain—helping prevent phishing attacks that target clients or opposing counsel.
- Prevents email spoofing: Stops attackers from sending fake messages “from” your firm.
- Builds client trust: Ensures every email truly comes from your verified domain.
- Improves deliverability: Authenticated messages are less likely to land in spam or junk folders.
Encryption protects confidentiality. DMARC protects credibility. Together, they create a secure, ethical communication foundation for modern law firms.
