1040. Divided co-ownership of an immovable that is built by an emphyteutic lessee or that is subject to superficies may be established if the unexpired term of the lease or right, at the time of publication of the declaration, is over 50 years.
In cases arising under the first paragraph, each co-owner, dividedly and proportionately to the relative value of his fraction, is liable for the divisible obligations of the emphyteutic lessee or superficiary, as the case may be, towards the owner of the immovable subject to emphyteusis or superficies. The syndicate assumes the indivisible obligations.
