In the name of Allah, your request is a transgression from you on your parents, because the house was your father's or parents'. You did not have a share in it. How come you say “my share” while the owner is alive? As for the parents’ deprivation of you, it is under the title of the will, then the will is executed with one third and the rest is distributed among the heirs. You shall have a share after their death. If their act is under the title of a gift of the house to your brother, then the owner can do with his property what he wants. However, the religious legislator forbade the preference of some heirs over others, especially among sons, even if the preference is valid. Allah knows best.
