In the order or decree, the court must name the persons and the proportions or parts to which each shall be entitled, and such persons may demand, sue for and recover their respective shares from the executor or administrator, or any person having the same in possession. Such order or decree is conclusive as to the rights of heirs, legatees or devisees, subject only to be reversed, set aside, or modified on appeal.
