May a Missouri lawyer practice from a virtual office without maintaining a physical office?

Plain-English summary

Missouri does not require a licensed lawyer to maintain a physical office. Rule 6.01(b)(1) requires a current mailing address and email address, but the mailing address may be an office, home, post office box, or similar place where the lawyer regularly receives mail.

The Rules of Professional Conduct apply equally to virtual and physical practice. The opinion identifies technology competence under Rule 4-1.1 Comment [6], diligence under Rule 4-1.3, regular client communication under Rule 4-1.4, and confidentiality under Rule 4-1.6.

Rule 4-1.6 requires reasonable efforts against unauthorized access or inadvertent or unauthorized disclosure. Comment [15] identifies factors including information sensitivity, likelihood of disclosure without added safeguards, cost and implementation difficulty, and adverse effects on the lawyer's ability to represent clients. Comment [16] addresses precautions for transmitting confidential information, including sensitivity and legal or contractual privacy protection.

Virtual practice also leaves supervision duties intact. Rule 4-5.1 governs other lawyers in the firm, and Rule 4-5.3 governs nonlawyers, including vendors. The opinion cites prior Missouri opinions addressing shredding vendors and cloud computing.

In practice

Under this opinion, virtual practice changes the office format, not the governing duties. The lawyer may work without a physical office if the registration address receives mail regularly and the practice satisfies the Rules' technology, service, confidentiality, and supervision requirements.

Question 1: Missouri licensed lawyer asks if it is permissible to practice in Missouri from a virtual office, or is a physical office is required?

Answer 1: A physical office, (i.e. a brick-and-mortar building), is not required for a Missouri licensed lawyer to practice law in Missouri from a virtual office. Rule 6.01(b)(1) requires, among other information, for a Missouri lawyer to register “[t]he lawyer’s current mailing address and e-mail address.” That mailing address may be an office, home, post office box, or similar location, so long as it is a place where the lawyer regularly receives mail. See Informal Opinions 950069 (practicing from a home office); 990213 (practicing from a mobile office).

Question 2: Missouri licensed lawyer asks if there are additional ethical considerations when practicing virtually?

Answer 2: The Missouri Rules of Professional Conduct apply equally to lawyers whether practicing virtually or in a physical office. Some ethical considerations include taking steps to ensure competence in using technology as provided in Comment [6] to Rule 4–1.1, continuing to ensure diligence in accordance with Rule 4–1.3, and maintaining regular client communication as required by Rule 4–1.4. Missouri Lawyers are still required to maintain confidentiality of clients’ information and “make reasonable efforts to prevent the inadvertent or unauthorized disclosure of, or unauthorized access to, information relating to the representation of the client.” Rule 4–1.6. Comment [15] to Rule 4–1.6 provides guidance that lawyers are required to act competently to safeguard client information from: (1) unauthorized access by third parties; (2) inadvertent or unauthorized disclosure by the lawyer or other persons who are participating in the representation of the client; (3) and/or inadvertent or unauthorized disclosure by those who are subject to the lawyer’s supervision. Comment [15] to Rule 4–1.6 further provides factors to be considered in determining reasonable efforts to prevent such unauthorized access or disclosure, including, but not limited to, “the sensitivity of the information, the likelihood of disclosure if additional safeguards are not employed, the cost of employing additional safeguards, the difficulty of implementing the safeguards, and the extent to which the safeguards adversely affect the lawyer’s ability to represent clients (e.g., by making a device or important piece of software excessively difficult to use).” Further, Comment [16] to Rule 4–1.6 provides guidance on a lawyer’s reasonable precautions to take when transmitting confidential client information, including “the sensitivity of the information and the extent to which the privacy of the communication is protected by law or by a confidentiality agreement.” Finally, lawyers should also pay extra attention to supervisory responsibilities over other lawyers in the firm as required by Rule 4–5.1, and nonlawyers, including vendors, as required by Rule 4–5.3.
