What Is Washington RPC 3.7?
Washington RPC 3.7 governs situations where a lawyer may be called as a witness in a case where the lawyer is also acting as an advocate. Commonly referred to as the “lawyer as witness” rule, it is designed to prevent confusion, protect the integrity of proceedings, and avoid conflicts between advocacy and testimony.
The rule recognizes that serving as both advocate and witness can create credibility concerns. A jury may struggle to separate a lawyer’s sworn testimony from their role as a persuasive advocate. Washington RPC 3.7 seeks to maintain fairness and clarity in the courtroom.
The Core Rule Under Washington RPC 3.7
When a Lawyer May Not Act as Advocate
Under Washington RPC 3.7, a lawyer generally must not act as an advocate at a trial in which the lawyer is likely to be a necessary witness.
The concern is twofold:
- The lawyer’s testimony may conflict with their client’s position.
- The lawyer’s dual role may prejudice the opposing party or confuse the factfinder.
If a lawyer’s testimony is necessary and material to the issues being decided, the lawyer typically must withdraw from serving as trial counsel.
Exceptions Under Washington RPC 3.7
Washington RPC 3.7 provides limited exceptions. A lawyer may serve as both advocate and witness if:
- The testimony relates to an uncontested issue
- The testimony concerns the nature and value of legal services rendered
- Disqualification of the lawyer would work substantial hardship on the client
These exceptions recognize that in some circumstances, disqualification would be unnecessary or unfair.
For example, testimony about attorney’s fees in a fee dispute may not require withdrawal from the matter.
Why the Rule Exists
Protecting Trial Integrity
The dual role of advocate and witness can undermine the appearance of fairness. Jurors may give undue weight to testimony from a lawyer who also presents arguments. Conversely, opposing counsel may be placed in the uncomfortable position of cross-examining a lawyer who is simultaneously arguing the case.
Washington RPC 3.7 protects the integrity of the adversarial process by ensuring that testimony and advocacy remain distinct roles.
Interaction With Other Ethical Rules
Washington RPC 3.7 often overlaps with other professional conduct rules, including:
- RPC 1.7 – Conflict of Interest, if the lawyer’s testimony creates divided loyalties
- RPC 1.16 – Withdrawal, if continued representation violates ethical obligations
- RPC 3.4 – Fairness to Opposing Party, if the dual role could prejudice the proceeding
Attorneys must carefully evaluate whether their participation as a witness will create ethical conflicts requiring withdrawal.
Practical Examples
Situations where Washington RPC 3.7 may arise include:
- A lawyer who personally observed events relevant to a disputed contract
- An attorney involved in drafting documents that are now challenged as fraudulent
- A criminal defense lawyer who becomes a witness regarding statements made during an investigation
In each situation, the key question is whether the lawyer’s testimony is necessary and whether it relates to contested matters central to the case.
If another witness can provide the same testimony, withdrawal may not be required. Courts examine necessity carefully before ordering disqualification.
Consequences of Violating Washington RPC 3.7
If an attorney improperly continues as trial counsel while serving as a necessary witness, consequences may include:
- Disqualification from the case
- Delays or mistrials
- Appeals based on procedural unfairness
- Professional discipline
Courts take this rule seriously because it directly affects trial fairness and credibility.
Why Washington RPC 3.7 Matters to Clients
Clients sometimes prefer continuity with the lawyer who has handled their case from the beginning. However, if that lawyer becomes a key witness, ethical rules may require a transition to new trial counsel.
Understanding Washington RPC 3.7 helps clients appreciate that such changes are not strategic maneuvering—they are ethical safeguards built into Washington’s professional conduct framework.
If you are involved in litigation and questions arise about attorney testimony or disqualification, experienced counsel can help navigate these complex ethical considerations.
