How is an inherited four-story house divided among the heirs (a son, a grandson, 4 daughters, a granddaughter, and a wife), given that some floors are rented to the son, another is inhabited by the son, and a third is inhabited by the eldest son who died before him and has heirs? And how are 5 residential apartments distributed if the house is demolished and an apartment building is constructed in its place?

The grandson does not inherit from his grandfather if there is an uncle. The aforementioned properties are considered the deceased's estate, to be divided among the heirs according to their prescribed shares. A lease contract is not terminated by death, and the heirs divide the rent among themselves. The house rented with a perpetual lease is divided among the heirs, and its contract is invalid due to the absence of a specified term. The house built by the son, with its construction cost deducted from the rent, is inhabited by the son until the end of the agreed-upon term. If the heirs agree to demolish the old building, they may do so, and they become partners in the land according to their prescribed shares. If the deceased left behind only a wife, a son, and four daughters, the wife receives one-eighth (6 shares out of 48), and the remainder goes to the son (14 shares) and the daughters (7 shares for each daughter). The son's son and the son's daughter receive nothing, as they are excluded by the presence of the son.
