1) it is necessary to peruse the will to advise
2) it appears that the mother had only life interest in property
3) only on her demise property would devolve on 3 sons
4) daughters have no share in property
5) I presume aunty you are referring to is deceased son wife
6) she would inherit her husband share in property as per her father in law will
7) if as per will property would devolve on sons only on mother demise aunty cannot transfer her share to uncle by gift deed
8) no consideration should be mentioned in the gift deed as aunty is not receiving any money from uncle
