1993

What must a Missouri lawyer do when a flood destroys unsalvageable closed client files and items of intrinsic value?

The lawyer must identify the affected files, notify current and former clients, assist them as reasonably practicable, and dispose of ruined material confidentially. Electronic storage is allowed…

How may a Missouri lawyer replace a trust account after someone creates a fraudulent check on it while client checks remain outstanding?

May a Missouri lawyer submit a publicly filed client motion as a job-application writing sample?

Not without informed consent or effective removal of identifying information. Public filing does not remove Rule 4-1.6 protection; even with consent, the opinion calls for considering redactions,…

No. Even when Rule 5.28 makes a later reinstatement retroactive, the lawyer must follow Rule 5.27 after the suspension order and may not practice while suspended.

What Missouri license status must a retiring lawyer keep to represent family, friends, or pro bono clients?

The opinion requires active Category 1 status to represent family, friends, or pro bono clients. Inactive status permits none of that work; Rule 6.01(o) concerns an enrollment-fee waiver for…
