What does a Missouri lawyer owe clients after a supervised nonlawyer assistant discloses their confidential information?

Plain-English summary

The lawyer learned that a supervised nonlawyer assistant disclosed client confidences to third parties, possibly including opposing parties. The opinion applies Rule 4-5.3 to the firm's safeguards, the lawyer's supervision, and responsibility for the assistant's conduct.

Rule 4-5.3 calls for reasonable efforts to maintain firm measures that give reasonable assurance of compatible assistant conduct and reasonable efforts to ensure the assistant actually follows the lawyer's professional obligations. The lawyer is responsible for the assistant's misconduct if the lawyer ordered or ratified it, or knew of it while consequences could be avoided or mitigated and failed to take reasonable remedial action.

The needed mitigation depends on the disclosure's nature, recipients, and possible results; contacting third parties may be required to avoid or mitigate consequences. Under Rule 4-1.4, the lawyer must disclose the breach to all affected clients and explain enough for informed decisions. The office does not decide any additional duties under substantive law.

In practice

On the stated breach, the opinion requires notice and explanation to every affected client. It makes mitigation fact dependent and identifies conditions under which the lawyer is responsible for the assistant's misconduct.

Common questions

Q: Must the lawyer tell affected clients about the disclosure?

A: Yes. The opinion requires disclosure to all affected clients and an explanation sufficient for informed decisions under Rule 4-1.4.

Q: When is the lawyer responsible for the assistant's misconduct?

A: If the lawyer ordered or ratified it, or knew of it while consequences could be avoided or mitigated and failed to take reasonable remedial action.

Q: Does the opinion always require contacting third parties?

A: No. It says that may be required if contact would avoid or mitigate consequences; the response depends on the disclosure's nature and recipients.

Question: What are Attorney’s ethical duties upon learning that a nonlawyer assistant who was under Attorney’s supervision disclosed client confidences to third parties and possibly to opposing parties, and how can Attorney prevent future breaches of confidentiality?

Answer: Attorney’s ethical responsibilities regarding nonlawyer assistants are governed by Rule 4–5.3. Attorney is obligated to make reasonable efforts to ensure the law firm has in effect measures giving reasonable assurance that all conduct of Attorney’s nonlawyer assistants is compatible with Attorney’s professional obligations. Rule 4–5.3(a). Attorney must make reasonable efforts to ensure an assistant’s actual conduct is compatible with Attorney’s professional obligations. See also Comment [1] to Rule 4–5.3. Attorney is responsible for the nonlawyer assistant’s misconduct if Attorney ordered or ratified the conduct or if Attorney knew of the conduct at a time when consequences could have been avoided or mitigated but failed to take reasonable remedial action. Mitigating actions required by the rule depend on the nature and recipients of the disclosures and the possible results. Attorney may be required to contact third parties if doing so would work to avoid or mitigate the breach’s consequences. Attorney also may have duties governed by substantive law about which this office cannot give an opinion. Pursuant to Rule 4–1.4, Attorney must disclose the confidentiality breach to all affected clients and explain the matter to the extent reasonably necessary to permit the client(s) to make informed decisions about the representation(s).
