Full Text of Rule 4.6
Plain-English Summary
Rule 4.6 keeps the court and the other side current on who is handling a case. The moment a lawyer agrees to represent someone in a pending superior court matter, that lawyer must promptly tell the calendar clerk in writing — and, depending on the type of case, also notify the district attorney in a criminal action or opposing counsel in a civil one. The notice needs the basics: that representation exists, the client’s name, the case name and number, and the lawyer’s firm name, office address, and phone number.
The duty doesn’t end once that first notice goes out. Anytime the representation changes — a new lawyer takes over, or the existing lawyer’s name, address, or phone number changes — the same people need to hear about it right away. That keeps calendar clerks scheduling matters correctly and keeps opposing counsel from serving papers or making calls to a lawyer who is no longer on the case.
