Retention or Employment of Attorneys
The state’s office of the Attorney General (OAG) has the exclusive right to represent the state of Texas before the Texas Supreme Court (or the Supreme Court of any state in which the state of Texas may be a party) and any of the state’s Court of Appeals. District and county attorneys have the exclusive right to represent the state of Texas in all cases in the district and inferior courts in their respective counties. This right, however, is subject to any specific statutory or constitutional authorization or requirement for the OAG to represent the state in those courts.

A contract for legal services between a state agency and an attorney who is not a full-time employee of the state agency is valid only if the office of the Attorney General (OAG) approved the contract. The OAG may require the agency to obtain the services through a competitive procurement process, under conditions prescribed by the OAG.
