What happens when a co-owner does not pay his/her charges?

The building manager can sue the co-owner without prior authorization of the General Assembly. Once the judgment has been rendered the building manager can confiscate the salary/pension or, as the case may be, the rent of the tenant of the co-owner. (Art. 14 de la loi du 16 mai 1975 portant statut de la copropriété des immeubles bâtis)
