The pre-emptor's right of pre-emption shall lapse in the following cases: 1. If they partition with the purchaser of their co-owner’s share, or purchase the share from them, or lease it, even if unaware that such act results in the lapse of their right of pre-emption. 2. If they sell their own share, even after becoming aware that their co-owner had previously sold their share. 3. If they remain silent for two months without impediment from requesting the taking of the share by pre-emption, despite knowledge that the purchaser has built or planted thereon. 4. If they remain silent for two months without impediment from demanding pre-emption from the date they become aware of the co-owner's sale of their share, if they are present in the State, or from the date of their return from travel and knowledge of the co-owner's sale, if they were absent at the time of the sale. If they deny knowledge of the sale and the purchaser claims they had knowledge, the pre-emptor shall be believed in their denial upon taking an oath.
