Key legal question
Whether the encroachment servitude included an enforceable duty to build a load-bearing terrace slab for the dominant parcel.
Extracted holding
No. Such a duty was not part of the servitude; it was at most a personal contractual obligation.
Extracted reasoning
Under Art. 730 CC, a servitude may impose only passive duties on the servient owner, except for accessory obligations or maintenance duties. The alleged construction duty did not facilitate the exercise of the encroachment servitude and was therefore not accessory; it also did not fall under Art. 741 CC.
