Am i entitled to part of my grandmothers home when she passes

If your grandmother has a valid Will, her property will pass as she wrote in that Will.  No one can change it but her. If your grandmother does not have a valid Will, her property will pass under the Texas laws of descent and distribution.  If your grandfather is dead and your grandmother's only children and Delores and Jim, half (after all the bills are paid) will pass to each or, if they are deceased, to their children. Whether your uncle can kick you out of your grandmother's house before a court appoints someone as executor (valid Will) or administrator (no valid Will) to settle her estate depends on the situation.  While your grandmother is alive, an agent under a Durable Power of Attorney may have authority over her property (if the document so states).  After she dies, no one has authority over her property until the court appoints them as executor or agent or approves a Small Estate Affidavit.  If she has no valid Will and all she leaves is a house, the heirs could record an Affidavit of Heirship in the deed records -- but courts will not enforce it until it has been of record for five years with no one complaining that it is incorrect.
