If father died, what is the procedure to Change property ownership in name of legal heir sons?

If the last Will was limited to that single property which is no longer available, then the Will seems to   have become infructuous.  The narrations in the Will may not be  applicable for devolution of other assets of deceased person.

A succession Certificate seems to be the correct way forward.  Consult your Advocate for correct way forward.

Sir, last will property was the only property no other property of the father so basically he bequeathed all he had by that last will. Now, as that property was sold, and his son was also made a party by that father in the sale deed selling that property, Can't that will and this action of father be sufficient to get succession certificate in name of his son in the present property bought from selling that last property?

Who sold that property if the testator sold it during his life time will cannot be enforced  ,will becomes invalid.even it is registered.

Hello,

If the property sold by the father during his lifetime which was mentioned in the will in that case will become invalid. If the new property purchased from the sale proceeds of the last sold property then you have to get a legal heirship certificate from the court. The last will has no concern with new property bought.
