Agencies working with the CSO

South Australian government agencies use the Crown Solicitor's Office (CSO) for their legal advice. 


In some circumstances, public authorities can use private legal practitioner but must seek the advice of the Crown Solicitor first. See Private law firms and practitioners for more information.
