1. Characterisation of the sale by lots
The transaction must constitute a sale by lots within the meaning of the two laws referred to. In concrete terms: division into co-ownership lots, unit-by-unit resale, and triggering of the pre-emption right of the sitting tenants, either because the sale of an occupied residential lot, following the division of the building, constitutes an offer to sell to the tenant or bona fide occupant, whoever the intended purchaser may be (Law 75-1351, art. 10), or because a notice to quit for sale is served (Law 89-462, art. 15).
