Judge Aaron H. Katz

Judge Aaron H. Katz serves on the San Diego Superior Court and brings a career background that spans private civil litigation, criminal prosecution, and extended judicial service. He earned his B.A. from UCLA in 1983 and his J.D. from Southwestern Law School in 1986. Before taking the bench, he worked as an Associate at Chapin, Shea, McNitt & Carter in San Diego and as a Deputy District Attorney for the San Diego County District Attorney's Office. His initial appointment to the Superior Court was made by Governor Gray Davis on April 2, 2003, filling the vacancy created by the resignation of the Hon. Bonnie Dumanis. A subsequent appointment is recorded as being made by Governor Gavin Newsom effective January 1, 2022. Judge Katz's documented recent case activity includes small claims, unlawful detainer, and general torts matters in San Diego County Superior Court. His pre-bench experience as a Deputy District Attorney gives him direct exposure to criminal procedure and prosecutorial practice, while his time in private civil litigation at Chapin, Shea, McNitt & Carter reflects familiarity with civil motion practice and client representation. With over two decades on the bench, he is among the more experienced sitting judges in San Diego County. No analyzed rulings, attorney observations, or ingested content are available for this profile. As a result, specific patterns regarding his ruling tendencies, courtroom demeanor preferences, or procedural inclinations cannot be stated with evidentiary support. The guidance below is grounded exclusively in his verified career background and documented case activity.

Given Judge Katz's background as a former Deputy District Attorney, attorneys handling any matter with criminal law overtones — including civil cases involving fraud, intentional torts, or conduct-based claims — should be prepared for a judge who is familiar with evidentiary standards and burden-of-proof analysis from a prosecutorial perspective. His civil litigation background at a private firm also means he has direct experience with the demands placed on counsel in civil motion practice. His documented recent docket includes small claims, unlawful detainer, and general torts matters. Attorneys appearing in these case types should ensure their factual records are clean and well-organized, as these matter types typically move quickly and judges with broad dockets reward concise, well-prepared presentations. Procedural compliance and thorough documentation are baseline expectations in these case categories regardless of judicial preference. Because no ruling analyses or attorney observations are available, attorneys should independently research recent published orders or contact colleagues who have appeared before Judge Katz to supplement this profile before any significant hearing. Relying solely on background data without courtroom-specific intelligence carries inherent risk in high-stakes matters.
