This is the regarding to get clarification on property transfer between my father in law(Father in law have 2 daughters, i married his 2nd daughter) and his elder daughter(who has been adopted to his elder brother). My father in law and his elder brother were together for 40 years. My father in law's brother who passed away one year back and wrote(willed) his property into two half(one for my father in law and another half to his adopted daughter). Now decided to give back the half of the property to my father in law. While transferring the property , Does she has enough power to return back to my father in law(with the help of willed)? Is there any rights for her son/daughter in transferring the property(now or future)?
