Miss. Code § 21-15-25
The governing authorities may annually appoint an attorney-at-law for the municipality, prescribe his duties and fix his compensation, and/or they may employ counsel to represent the interest of the municipality, should the occasion require. For services and duties which the regular city attorney is not required to perform as a result of his employment as such, and which are not covered by the regular compensation paid him, such municipal attorney may be employed and compensated additionally. In cases where an attorney, whether same be the regular municipal attorney or another, shall be employed in the matter of issuing or refunding of bonds and the drafting of all orders and resolutions in connection therewith, the governing authorities shall have the power to pay reasonable compensation to such attorney, but in no instance shall such compensation so paid exceed one per cent (1%) of the bonds issued or refunded; however, where the regular contract of employment and compensation paid to the municipal attorney covers and includes services in connection with the issuing or refunding of bonds, then such regular municipal attorney shall not be paid additional compensation for such services.
Should the services and duties required of a regular municipal attorney at any time during his term of office become greater than that anticipated by the governing authorities at the time of his appointment, the governing authorities, by unanimous vote, and on proper finding, may increase the compensation of such attorney for the remaining portion of his term in such amount as the governing board may find and adjudge to be fair and reasonable to compensate said attorney for his excessive and unanticipated services and duties.
