Article 3 of the UUPA states that the acknowledgment of the existence of Ulayat rights of the customary law community as long as in reality it still exists, meaning that if in fact it does not exist, then the Ulayat rights can no longer be recognized, cannot be revived and new Ulayat rights cannot be created.
