La. Stat. tit. 38 § 1620
The board of commissioners of every drainage district created under the provisions of this Part may employ an attorney, to act for the drainage district, and to advise the board of commissioners. His employment shall be evidenced by resolution of the board and by an agreement in writing, which as far as possible, shall specify the amount to be paid to the attorney for all services to be rendered by him. The attorney shall conduct all legal proceedings and suits in court where the drainage district or any sub-drainage district thereof is a party or interested, and in all legal matters affecting the district or any sub-district shall advise the board of commissioners, all officers, employees, or agents thereof, and generally, shall look after, supervise, and attend to all matters of a legal nature affecting the drainage district, or any sub-district. When the board of commissioners may deem it necessary, they may, by and with the advice of the attorney and under like terms and conditions, employ an additional attorney or attorneys. For the work done by the attorney or attorneys in connection with the organization of the district, the assessing of benefits and the creating of debt and issuing of bonds, the board shall pay a fee not in excess of one and one-half per cent of the total benefits assessed by the board of appraisers as confirmed by the court.
