The ratio is due from the value of the property given at the time of the partition, based on its condition at the time of the gift.
If the property was alienated before the partition, the value it had at the time of alienation is taken into account. If a new asset has been subrogated to the alienated asset, the value of the new asset at the time of partition is taken into account, based on its condition at the time of acquisition. However, if the depreciation of the new property was, due to its nature, unavoidable on the day of its acquisition, the subrogation is not taken into account.
All unless otherwise stipulated in the deed of gift.
If it results from such a stipulation that the value subject to report is less than the value of the property determined in accordance with the valuation rules set out in Article 922 below, this difference forms an indirect advantage acquired by the donee outside the inheritance share.
