Mismanagement in name of property acquisition

It is sole discretion of titleholder (owner) to retain or transfer, none can compel. 

Contact a local advocate if you are Hindus and the family is joint still, and at the time of acquisition of the property he younger brother is not having sufficient source of income to acquire such property with his own resources and if he has not disclosed in any official documents of this acquisition.   However, if the uncle is in possession of the property ask him to continue the possession.   Disclosing dates, the present status of possession, knowledge of this transaction within family members are essential for getting any guidance.  (There are umpteen cases in litigation in the same manner as while granting licenses for some establishments they seek that dealer must have a property in his name (Net worth/ or retail outlet site) as essential qualification, and accordingly when  the property is being named in the name of one son to make him qualify for such dealership, later that son claims that it is his absolute property depriving all other family members of their rights on such property acquired with his father's money)

You need to examine the language used in the sale deed to proceed further. Better show the title deed to a reliable Lawyer and seek his guidance.

1. Who is enjoying the property or under whose posession the property is;

2. Whether the property is mutated in favour of the younger brother and who s paying the taxes.

Law cannot offer any solution, admittedly, had been benami and such transactions are prohibited by law.
