you have not mentioned when your friend father purchased property ? when did friend father expire?

you have only mentioned that property was purchased by your friend father through power of attorney and registration was done in March 2004 .

query is not clear .

based on limited facts available i presume your friend father purchased property through regd power of attorney and registration was done in his favour in 2004 . your friend father is absolute owner of the property . he can sell the property in favour of purchaser .

You have mentioned that the property was purchased by your friend's father and the will is registered. Do you mean the will of this property made your friend's father? If any will has been made by him then the property will vest in terms of the will.

When the property has already been registered in his name then the question of it being registered again does not arise. The rights, if any, of your friend are subject to the will made by his father.
