You missed the point.Yes shes the last sibling. No other offspring but my brother and I. No wills. It was always meant to keep passing down the land. Almost all is graze and farmland. One section will be worth a little more being its next to a lake/ camping spots/ golf course/ housing edition.
Did your mother and Uncle have any siblings that preceded them in death? Unless stillborn, it could easily impact the division of the property.
