The co-ownership gives rise to expenses relating to the maintenance of the common portions and the day-to-day administration of the syndicate. Administrative, maintenance, replacement, improvement or alteration expenses of the common portions are divided among the co-owners. General common expenses are to be distinguished from particular common expenses, which are allocated under different rules. In the first case, it is the relative value of each fraction that is used to establish the co-owners contribution. As for particular common expenses arising from common portions for restricted use, the co-owners using them are alone responsible of the expenses resulting therefrom.
