Phone Interpreters for Law Firms: Serving Spanish-Speaking Clients the Right Way

A client cannot make informed decisions about a case they do not fully understand. For attorneys in Seattle, where Spanish-speaking clients are part of everyday practice, language access is a professional responsibility as well as a service question.

Language access is an ethics issue

The American Bar Association addressed this directly in Formal Opinion 500. Under the duties of competence (Model Rule 1.1) and communication (Model Rule 1.4), attorneys often must take affirmative steps to communicate effectively with clients with limited English proficiency, which may require engaging an interpreter, translator, or language technology. The opinion also says that when a lawyer and client cannot communicate with reasonable efficacy, the lawyer must take steps to engage a qualified and impartial interpreter.

In Washington, the state bar's ethics committee has published its own guidance on language access. It notes that lawyers have a duty to provide written or oral translation of any document whose contents are material to the case.

Why qualified beats convenient

It is tempting to let a relative or friend interpret. The ABA opinion warns against relying on them without care, since a person close to the client may be biased by a personal interest in the outcome, and may end up counseling the client rather than only conveying what was said. The lawyer must also consider whether the interpreter can speak and understand both languages fluently, accept responsibility for confidentiality, and translate accurately without adding anything.

A professional interpreter has no stake in the case, is trained for accuracy, and understands that what they hear stays private.

Protecting confidentiality

When an attorney brings in an interpreter, the lawyer must make reasonable efforts to ensure client confidentiality is protected. Under Model Rule 5.3, the lawyer is also responsible for supervising nonlawyers who assist in the representation and making reasonable efforts to ensure the person's conduct is compatible with the lawyer's professional obligations. In practice, that means:

• Confirm that your interpreter provider treats every call as confidential.
• Brief the interpreter before sensitive conversations.
• Document that you used a qualified interpreter and why.

Washington case law has also addressed interpreter confidentiality and privilege in criminal proceedings, so check current state authority and your own bar's guidance for your practice area.

Making sure the message actually lands

Interpreting is more than word-for-word conversion. The ABA opinion says that when language considerations affect communication, the lawyer must ensure the client understands the legal significance of translated or interpreted communications, and that the lawyer understands the client, including how cultural and social assumptions may affect meaning. Good habits include:

• Speaking in short, complete sentences and pausing for the interpreter.
• Asking the client to explain key points back in their own words.
• Avoiding idioms and unexplained legal jargon.

Where phone interpreting fits best

Phone interpreting works well for initial intake calls, quick case updates, scheduling, and follow-ups when a client cannot come to the office. It is often available on demand, which helps when a client calls with an urgent question. For long strategy meetings, court appearances, or situations where the client needs to read documents together with the attorney, plan for an in-person or otherwise certified interpreter instead.

Why this matters in Washington

Spanish is the most common non-English language in Washington. About 428,422 Washingtonians living in households with children, or 11.7%, speak Spanish at home. Around 71,373 of them live in households where no one over 14 speaks English very well, so many families cannot rely on a bilingual relative for complex legal matters.

Bottom line

For law firms and immigration attorneys, working with a qualified interpreter is part of communicating competently. If you want an on-demand option for Spanish-language calls, you can explore ablio's phone interpreting service or read more on our Seattle Spanish Interpreter page.
