§ 116.530.Attorney participation

Section 116.530(a) states California’s best-known small claims rule in plain terms: no attorney may take part in the conduct or defense of a small claims action, except as this section itself permits. That ban is a deliberate structural choice, consistent with the accessible, low-cost forum § 116.120 describes — it keeps both sides on equal footing at the hearing, without one party gaining an advantage from legal representation the other cannot use.

Subdivision (b) sets three narrow exceptions where the ban does not apply: an attorney appearing by or against themselves, an attorney appearing by or against a partnership in which they are a general partner and every partner is an attorney, and an attorney appearing by or against a professional corporation of which they are an officer or director and every other officer and director is also an attorney.

Subdivision (c) draws a careful line between taking part in the hearing itself and helping outside of it. Nothing in this section stops an attorney from advising a party before or after the action is filed, from testifying to facts within their personal knowledge that they are competent to testify to, from representing a party on an appeal to the superior court, or from representing a party in connection with enforcing a judgment. In short, a lawyer can prepare you, testify as a fact witness, and step in once the case moves past the small claims hearing itself, but cannot appear at the hearing to argue the case for you.
