First and foremost, the Power of Attorney needs to be examined to ensure that it is very clear and there are no ambiguities therein because of which the POA holder could include his name.  If the POA is clear and the purpose of the POA is clearly defined and the POA holder acted in violation of the trust vested in him through the contents of the POA, it is a clear case of cheating. Your Father's friend can initiate legal action against his brother ie. the Power of Attorney Holder and also to the person who sold the property who might have unwittingly cooperated with the POA holder in including the name of the POA holder beside the Registration Officials.

Therefore, your Father's friend may issue a Legal Notice to start with to the POA holder and the Vendor who sold the property, and to the Registration Official who is supposed to verify the document before Registering and register it in the correct name. If there is no satisfactory reply or action, with the help of a local lawyer to file a case against the POA Holder, Registration Official and the Vendor to rectify the mistake.

Ms. Arpita-

You have replied to very many query suggesting your in depth knowledge of law. And many such queries have been profoundly appreciated. Certainly you are well aware, more than many of us,  of the legal course that could be adopted and initiated in the instant case.

As such, why this query?

As per you the power agent has committed fraud and managed to acquire 50% share in  the property  to his name fraudulently.

Thus he is liable to prosecuted for the fraudulent acts he committed  provided the evidences suggest that he has committed this offence.

Hence you first ascertain and collect evidences before taking any legal action against him so that you do not get hurdles in your case after filing it.
