La. Uni. R. Ct. Appeal. 2-1.17
Notwithstanding the foregoing requirements, and subject to the minimum requirements provided by local rules of the Courts of Appeal, the parties may designate, in writing, portions of the record to constitute the record on appeal, as provided by law. If the Court of Appeal determines that it cannot undertake a proper analysis of the case on appeal without additional pleadings and/or transcripts, the court may require that additional pleadings and/or transcripts be supplemented into the record. The appellant shall be responsible for any cost associated with transcribing additional portions of the record not originally included in a designated record, and any cost associated with supplementing the record with the additional pleadings and/or transcripts.
