Transfer of property from son to father

My father has done everything for my brother and his wife's who lives in Bhopal Madhya Pradesh to make them settle financially. After their marriage my father gave many of their house installment from his pension. After my brother job's gone,my father invested all his savings and pension to bought him a commercial shop. And many more such thing spend on brother and his wife. His biggest mistake is all the money is his but everywhere he has put my brother's name and home is in joint name of my brother and his wife. Now my brother's wife has always mentally harrased my brother because of her basic nature of untrust,always suspicious even after 2 girl child and now it has gone to the limit that she has even commited adultery and now when my brother wants to separate she is blackmailing him by saying i will put wrong cases against you and your family and trying to extort money by saying if you want to do it mutual i will take everything. My brother is saying give her everything jist to get rid of her but Now my father dont have anything left with him other than their on going pension,he is worried that they dont even had saving if any of them(mother and father) get sick on top of it if son will come on road how will he again support him. My brother is working as a freelancer with no fixed income source and his wife is in government job. How can my father take back the property from my brother,please advice
