Dear Nilesh,
As per your query it seems that you want to transfer your property in your younger brothers name so that in future your wife may not claim on your property?
Is it the situtaion or else?
Further you may transfer your share of proprety in your younger brothers name and they may also give you power of attroney but as per recent law, on the bases of power of attorney, you cannot claim right of ownership on the land. So be careful, if you have full faith on your brothers only then do the same else better to consult any local lawer or consult me personally, i will guide you the other way out.
Good luck.
Regards
