La. Civ. Code art. 688
Current with changes from the 2024 Legislative Session
A landowner has the right to demand that the branches or roots of a neighbor's trees, bushes, or plants, that extend over or into his property be trimmed at the expense of the neighbor.
A landowner does not have this right if the roots or branches do not interfere with the enjoyment of his property.
