(a) Except as provided by Subsection (b) or (c), a criminal district attorney must meet the qualifications and give the bond required of a district attorney by the constitution and general law.
(b) Instead of the bond required under Subsection (a), a criminal district attorney may obtain coverage from a county government risk management pool created under Chapter 119, Local Government Code. Coverage obtained under the pool must be in the same amount and satisfy the same bond conditions otherwise required by this section.

(c) A criminal district attorney is not required to execute the bond required under Subsection (a) and may perform the duties of office if the commissioners court of the county the attorney serves by order authorizes the county to self-insure against losses that would have been covered by the bond. An order adopted by a commissioners court under this subsection shall be kept and recorded by the county clerk.
