What must a retiring Missouri solo lawyer do about current clients and decades of paper and electronic client files?

Plain-English summary

The solo lawyer planned to retire at year end and held paper client files dating back at least 40 years, plus paper and electronic files from the most recent five years. Rule 4-1.4 required notice to current clients. The lawyer was to finish matters that could be completed and give clients with unfinished matters enough notice to find other counsel, while taking reasonably practicable steps under Rule 4-1.16(d) and observing any tribunal notice or permission requirement under Rule 4-1.16(c).

Rule 4-1.22 permits confidential destruction of former-client files beyond its six- or ten-year holding periods unless an exception applies. Items of intrinsic value may never be destroyed. Files still within the applicable period belong to the former clients under Missouri Formal Opinion 115.

The lawyer and former client may agree to a shorter holding period at any time after the representation ends. The client must give informed consent confirmed in writing, and the lawyer must retain the agreement for the otherwise applicable six- or ten-year period. The opinion identifies transfer of the file to the former client or secure destruction as possible subjects of that agreement.

Paper files still within the holding period may be scanned consistently with Missouri Formal Opinion 127. Electronic copies remain subject to Rule 4-1.6, including when backed up to a cloud system. After retirement, the lawyer must give former clients contact information for requesting files the lawyer continues to hold.

In practice

Under this opinion, retirement requires separate treatment of active matters, older abandoned files, files still within Rule 4-1.22's holding period, and intrinsically valuable property. File format does not change confidentiality, and continued custody after retirement requires reachable contact information.

Common questions

Q: What notice is owed to current clients?

A: Rule 4-1.4 requires notice of the upcoming retirement. Clients whose matters will remain unfinished need time to find other representation and the protections required by Rule 4-1.16(d).

A: Files beyond Rule 4-1.22's six- or ten-year period may be destroyed confidentially unless an exception applies. Items of intrinsic value may never be destroyed.

Q: May a client agree to a shorter retention period?

A: Yes. The agreement requires informed consent confirmed in writing, and the lawyer must keep the agreement for the original holding period.

Q: May paper files be scanned?

A: Yes, consistently with Missouri Formal Opinion 127. The electronic files remain protected by Rule 4-1.6.

Q: What duty continues after retirement while the lawyer holds files?

A: The lawyer must provide contact information so former clients can request their files.

Question: Lawyer is a solo practitioner and is winding up Lawyer’s practice with plans to retire at the end of the year. Lawyer asks what notifications need to be sent to current and former clients. Also, Lawyer has client files in paper format going back forty (40) or more years, and more recent files from the last five (5) years are in both paper and electronic format. Lawyer asks how to handle these files upon retirement, and if there are any steps Lawyer may ethically take at this point to minimize how many files Lawyer will have to maintain after retirement.

Answer: As to notifications to current clients, Lawyer should provide notice to current clients regarding Lawyer’s upcoming retirement as part of lawyer’s duty to communicate pursuant to Rule 4–1.4. To the extent that matters for current clients can be concluded, that should be done. As to matters for current clients that Lawyer will not be able to complete, Lawyer should provide notice so that current clients may find other representation consistent with Rule 4–1.16(d) and take other steps reasonably practicable to protect their interests. Lawyer should consider if applicable law requires notice or permission of a tribunal to terminate the representation in accordance with Rule 4–1.16(c).

As to the client files, for former client files that are past the six (6) or ten (10) years holding requirement of Rule 4–1.22, the files are deemed abandoned and may be destroyed in a manner that preserves confidentiality unless an exception exists per Rule 4–1.22(a)-(d). See Missouri Informal Opinion 2021–03 (contract with vendor for disposal of client files). However, items of intrinsic value shall never be destroyed pursuant to Rule 4–1.22. Lawyer should consult Missouri Formal Opinion 118 – Unused Funds Remaining in Trust Fund, to see if the item of intrinsic value may be appropriately handled as a matter of law that is beyond the scope of the Rules of Professional Conduct.

For files of former clients that are within the six (6) or ten (10) years holding requirement of Rule 4–1.22, Lawyer should be mindful that those files belong to the former clients pursuant to Missouri Formal Opinion 115 – Withholding Client Property. Rule 4–1.22 permits Lawyer and clients to reach agreements for a Lawyer to hold files for a lesser period of time. For that to occur, the clients must provide informed consent, confirmed in writing, and Lawyer must maintain a copy of the agreement for the required six (6) or ten (10) years that the files were to be held. Informed consent is a defined term under Rule 4–1.0(e), that requires the communication of adequate information to the clients, including the material risks and reasonably available alternatives to the proposed course of conduct. Similarly, Rule 4–1.0(n) defines what constitutes a writing and signing of the writing. Rule 4–1.22 allows this agreement to be made at any point after the completion or termination of the representations. Lawyer may wish to seek the informed consent, confirmed in writing, of the affected former clients to either have them take possession of the files or to permit Lawyer to securely destroy their files. Lawyer may wish to consult with Lawyer’s risk management carrier for any additional guidance.

Further, since Lawyer has paper files that would fall within the holding requirement timeframes of Rule 4–1.22, Lawyer may wish to consider scanning those files consistent with Missouri Formal Opinion 127 – Scanning Client Files. As with paper files, Lawyer is required to consider the confidentiality of those electronic files consistent with Rule 4–1.6. If Lawyer will be backing those files up to a cloud-based system, Lawyer should consult Missouri Informal Opinion 2018–09 (cloud computing).

Finally, upon retirement, for former clients for whom Lawyer continues to securely hold files as required by Rule 4–1.22, Lawyer should provide contact information where Lawyer can be reached in the event files need to be requested.
