La. R.S. 13:5830

Three months after the institution of any suit, each constable may demand his fees from the party by whom the fees are due. On failure to pay, the judge of the city court may, after proof has been adduced of the correctness of the amount, contradictorily with the party against whom the motion is made, issue a writ of fieri facias in favor of the constable. Nothing in this Section shall be construed as preventing either constable from collecting his fees from the defendant at any time after judgment against such defendant.
