Civil law is not just different vocabulary
Louisiana's private law descends from the French and Spanish codes rather than English common law, and the Civil Code governs. The transfer document is an act of sale. La. Civ. Code art. 1839 requires a transfer of immovable property to be made by authentic act or by act under private signature; in practice it is passed before a notary as an authentic act, with two witnesses. Louisiana notaries are commissioned officers with drafting authority a notary elsewhere does not have. Recording is decisive: under La. Civ. Code art. 3338, rights created by instruments affecting immovables have no effect as to third persons unless registered in the parish conveyance records. An unrecorded sale binds the parties and nobody else.
