Key legal question
Whether the land register could be rectified to transfer the right of habitation from the base parcel to condominium unit yyy.
Extracted holding
No. The register contained no rectifiable error by mere oversight, and the conversion did not alter the applicant's legal position.
Extracted reasoning
The right of habitation was already opposable as entered on the base parcel; registering it against the unit would not change the substance of the right. There was therefore no mistake under Art. 977 CC and Art. 98 RRF.
