if The property is self acquired by your father by his own saving and effort then he need not discuss or seeking permission to any one. He can give to any one. state the facts clearly for further suggestions .
First, have clarity on the issue: In whose name the property stands in the title deed? What do you mean "handing over: Why you think that your father should consult his younger son while handing the property to his eldest son?
If the property belongs to the father and is self-acquired, during his lifetime, he can transfer the property through a legal document like a gift deed and he need not consult anyone for giving his property to anyone he wishes.
If your father has transferred his property by a registered deed to his son or to any person of his choice with regard to the property which is his own and absolute property, there is no legal infirmity in it.
As far as you or anyone is concerned to the property, you are a third person hence you do not have any rights or interest in the property, therefore you cannot claim any share in the property as a right neither you can raise any objection to your father's act of transferring the property to his elder son alone.
