Wash. Admi. And. Prac. R. LLLT RPC 5.9
Comment
[1] This Rule codifies the proposition that LLLTs may enter into fee-sharing arrangements and for-profit business relationships with lawyers. It is an exception to the general prohibition stated in Rule 5.4 that LLLTs may not share fees or enter into business relationships with individuals other than LLLTs. Rule 5.4 governs an LLLT's responsibilities with respect to individuals who are neither LLLTs nor lawyers.
[2] In addition to expressly authorizing intra-firm fee-sharing and business structures between LLLTs and lawyers in paragraph (a), paragraph (b) of the Rule sets forth limitations on the role of LLLTs in jointly owned firms, specifying that regardless of an LLLT's ownership interest in such a firm, the business may not be structured in a way that permits LLLTs directly or indirectly to supervise lawyers or to otherwise direct or regulate a lawyer's independent professional judgment. This includes a limitation on LLLTs possessing a majority ownership interest or controlling managerial authority in a jointly owned firm, a structure that could result indirectly in nonlawyer decision-making affecting the professional independence of lawyers. Lawyer managers, by contrast, will be required to undertake responsibility for a firm's LLLT owners by expressly assuming responsibility for their conduct to the same extent as they are responsible for the conduct of firm lawyers.
