For Washington law firms · State overlay
Washington firms apply ABA Op. 512 to RPC 1.5 absent a state-specific opinion.
A Washington-calibrated read of the engagement-letter clause library. Sourced from Washington RPC 1.5 (Fees) and the WSBA Standing Committee's published guidance under the Lawyer Education Committee.
What this overlay adds beyond the pillar
Washington's operational stance
Washington has not, as of May 2026, published a Washington-specific formal ethics opinion on lawyers' use of generative AI. Washington firms apply the ABA Formal Opinion 512 framework to Washington RPC 1.5 (Fees), which mirrors ABA Model Rule 1.5. The Washington State Bar Association tracks the state-by-state opinion landscape and the firm's practice expectations through the Standing Committee on Professional Ethics and the Lawyer Education Committee (LEC).
Rule 1.5 fee-treatment matrix applies unchanged. Washington RPC 1.5's text on reasonable fees and the requirement to communicate the basis or rate of the fee in writing for non-regularly-represented clients controls. The pillar's overhead-versus-pass-through framework — derived from ABA Op. 512 — operates without Washington-specific deviation. Pass-through of an actual third-party AI cost is permissible when disclosed; treatment of AI-saved time as billable is not.
Confidentiality and informed-consent posture follows ABA Op. 512. Absent a Washington-specific informed-consent floor, Washington firms apply ABA Op. 512's standard: informed consent before disclosing client confidences to a self-learning third-party AI, plus the standard Rule 1.6(c) reasonable-efforts analysis on vendor selection, data-handling, and retention. The pillar's Clause 01 (confidentiality and AI-tool disclosure) and Clause 03 (third-party processor consent) satisfy the Washington posture without modification.
The freshness loop is the Washington-specific operational addition. Washington firms watch the Washington Supreme Court Practice of Law Board, the WSBA Standing Committee on Professional Ethics, and the WSBA Ethics Line for forthcoming Washington-specific guidance. Until that guidance lands, the pillar's clause library and Rule 1.5 fee-treatment matrix apply unchanged. The freshness loop captures any WSBA-specific guidance the moment it publishes and routes a clause-library delta to the firm's risk partner.
