Louisiana Revised Statutes Tit. 47, § 2127.1. Immovable property; lots assessed together

If two or more lots or parcels of ground have been assessed in any year or years to the same tax debtor at a certain valuation for the whole together, without distinguishing the valuation of each lot or parcel separately, the tax collector is authorized, but shall not be obligated, to receive the proportion of statutory impositions under assessment fairly due upon any one or more of the lots or parcels separately. The proportions shall be ascertained and fixed by a certificate authenticated by the assessor and approved by the tax collector. The lots or parcels upon which the proportions are paid shall be free from the proportion of taxes pertaining to the other lots or parcels of the assessment.
