Every advertisement, website, letterhead, business card, profile, or other public material identifying the lawyer must clearly disclose both of-counsel relationships. Each firm must disclose the…

2020

Can screening prevent an of-counsel lawyer's current- or former-client conflict from being imputed to a Missouri firm?

No. An of-counsel lawyer is associated with the firm for Rule 4-1.10, so conflicts under Rules 4-1.7 and 4-1.9 are mutually imputed, and the rule does not permit screening to eliminate that…

2020

May a nonlawyer sign or authorize electronic transfers from a Missouri lawyer's trust account?

Yes, but only when the nonlawyer acts under the lawyer's direct supervision. Access must be limited and closely monitored because the lawyer's duty to protect client trust funds cannot be delegated.

2020

What must a Missouri lawyer do with trust-account funds whose owner cannot be identified?

No. Once deposited funds are good funds and belong to the lawyer, they must be transferred reasonably promptly to a personal or business account before being used for expenses.

2020

May a Missouri lawyer keep personal or firm money in a trust account as a cushion against mistakes or fraud?

No. The only permitted lawyer funds are the amount necessary to pay financial-institution service charges; keeping a cushion for any other purpose is prohibited commingling, and earned lawyer funds…

2020

Does Missouri Rule 4-1.5(e) regulate fee division between a firm and a lawyer accurately designated of counsel?

2020

What elements make a Missouri lawyer's relationship with a firm an accurate of-counsel relationship?

The lawyer must consult the client and explain the proposed agreement enough for an informed decision. Whether law permits withholding discovery covered by the agreement is a factual and legal…

2020

May a Missouri lawyer return or destroy client-file discovery under a protective order or settlement agreement?

A protective order may be obeyed after seeking permissible modification when the client refuses consent. A settlement may require return or destruction only with the client's informed written…

How are conflicts imputed when a Missouri firm's of-counsel lawyer provides case-by-case pro bono work at a nonprofit?

With case-by-case contract work and access only to assigned files, the nonprofit's other conflicts do not reach the firm, though the lawyer's own nonprofit matters do. Broader file access makes both…

2019

What must a Missouri lawyer disclose after missing a client's filing deadline, and may negotiations continue?

The lawyer must explain the limitations failure and relevant facts, address independent advice for a possible malpractice claim, and satisfy Rule 4-1.8(h) before settlement. Negotiations may…

2019

What must a Missouri lawyer do with opposing-party emails a client accessed using the opposing party's login?

2018

May a Missouri lawyer avoid a court appointment because the matter is in an unfamiliar area of law?

Not merely for unfamiliarity. The lawyer need not have prior experience if competence can be achieved through study and preparation; avoidance requires good cause, including inability to reach the…

2018

May a Missouri lawyer offer discount certificates for legal services at an educational seminar?

No. Legal-service information may be available to inquirers, but the lawyer or a nonlawyer presenter may not initiate an in-person promotion or discount offer. A later mailed solicitation is…

2018

May a Missouri lawyer answer a former client's negative online review using information the client already posted?

Generally no. An online review is ordinarily not a Rule 4-1.6(b)(3) controversy, and confidentiality covers all representation information regardless of source and facts that could lead to it; a…

2018

Must a Missouri lawyer report opposing counsel who appears intoxicated and impaired?

Yes if the lawyer knows opposing counsel was intoxicated while representing a client and obtains the reporting lawyer's client consent for representation-related disclosure. Suspicion is…

2018

2018

May a Missouri lawyer join a firm adverse to a client the lawyer substantially represented at the old firm?

Not in the same or a substantially related matter without the former client's informed written consent. The conflict reaches the new firm, Missouri does not recognize screening under Rules 4-1.9 and…

2017

May a Missouri firm defend County B criminal cases when one member is a part-time prosecutor in County A?

May a lawyer represent a father's guardian while also serving as the father's guardian ad litem in a child abuse case?

2017
