My aunt(second wife) possesses an entire ground floor of the inherited property(consists of G+1 floors) from my uncle. First floor house, which has been given to my uncle's first wife's(deceased) daughter as a gift deed. Uncle's daughter has sold it to some other party.
In this case, will my aunt has any right to stop the first floor owner to build one more floor above that. What are the rights & obligations of my aunt in this regards.
Please advise & suggest. Thanks.
