self acquired or inherited property

In herited means it may beancestral,if it is ancestral he can make will or gift for his share only.

I have put a very simple situation for a lawyer. but I have not got any concrete reply
please read my query.
If my father in law has inherited,does he have to divide equally between his one son and one daughter or he has the right to divide between son and daughter as he wishes,whether it is Will or Gift

The property inherited from father, grandfather or great grandfather becomes ancestral property.

• In an ancestral property, all the sons have a right by birth and therefore, the father cannot give the ancestral property to one son to the exclusion of others. After amendment of 2005 in the Hindu Succession Act, even daughters are coparceners and have a right in the ancestral property.

• A father cannot freely give the ancestral property to one son. In Hindu law, the ancestral property can be gifted only under certain situations like distress or for pious reasons. Otherwise, the ancestral property cannot be given away to one child to the exclusion of all others.
• For Muslim and Christians, there is no concept of ancestral property. The property can be given to one son as per the limit permitted under personal law for Muslims

Hope this helps
