right of son on fathers property

yes, all the property earned by father.

It's true if the property is not ancestral and is self acquired.

In case if he dies intestate, the son is also co-sharer with mother and his siblings.

Only Mr. GLN Prasad has given pertinent reply.

I agree with the Reply of Shri GLN Prasad.   He and Dr. MPS Ramani are excellent experts of lawyersclubindia.

But the Questioner says,  "....  if the father wants  ..." .

No question of dying intestate.

The person who asked the query says "If the father wants then only the son can get. If the father dies intestate he had not specifically wanted the son to get. Still the son gets.
