Hon. Nanette M. Warner


After serving as a Superior Court Judge in Pima County for over 24 years, in June 2010, Judge Warner transitioned from the bench to private practice where she emphasizes:

  • Dispute Resolution, including mediation, arbitration, and parenting coordination 
  • Family Law
  • Guardianships/Conservatorships
  • Expert Witness/Case Evaluation

In the area of Dispute Resolution, she serves as a mediator and arbitrator, primarily in family law and probate cases, including guardianship and conservatorship cases. Additionally, she serves as a parenting coordinator in family law cases. In the recent past, she also has limited practice in representing parties in contested family law cases. Previously, she was also on the court list for appointment to represent people who are the subject of guardianship and conservatorship cases in the Superior Court. She is also available for consultation as an expert witness and for a case evaluation.

From 2015 to 2021, Judge Warner served on the Commission on Trial Court appointments in Pima County after appointment by the Governor and confirmation by the State Senate. Judge Warner continues her community work by serving as a member of the Governing Body of the Arizona State Hospital, a board member of the Girls Scouts of Southern Arizona, and a board member of the Dance Advisory Board of the University of Arizona.  She has been a member of Women at the Top 2011, a  professional women’s group in Tucson. 


Judge Warner graduated from Georgetown University Law Center in 1976 and thereafter returned to Tucson to practice law. As a native Arizonan, she felt most at home in the clear blue skies and desert terrain of Southern Arizona. After being admitted to the Arizona State Bar in 1976, she practiced civil litigation, with an emphasis on complex personal injury, declaratory judgment, and employment cases. After being appointed to the Superior Court in December 1985, Judge Warner served on the Civil, Criminal, Family, and Juvenile benches. She did two rotations on the juvenile bench total of 9 years and served as the presiding juvenile court judge. She had three rotations on the family law bench and twice served as the presiding family law judge. Additionally, she had several rotations on the civil and criminal benches. She started the Mental Health Court in Pima County Superior Court for persons convicted of felonies who have serious mental illness and presided over several high-profile murder cases. Since leaving the bench, she continued her legal education by attending the Straus Institute of Dispute Resolution at Pepperdine Law School. She has continued to take continuing education in the areas of family law, probate, and dispute resolution.  

In 1999, she was awarded the American Bar Association award for judicial excellence for her work in leading the reformation of child welfare case handling in juvenile court. In 2006, she was selected as the Women of the Year for Pima County for her community work. She has received numerous awards and recognitions for her service to the legal system, courts, and community. She has also served as a Professor of Practice at the James E. Rogers College of Law, where she taught Advanced Family Law Practice. 

She serves as a Judge pro tempore and a judge recalled to service in the Superior Court in various counties in Arizona. She conducts settlement conferences in family law cases in Pima County Superior Court.
