Dr JC Vashista Thank you sir for your reply. Just one clarification on the Q1 Mr X has aquired this property from family partition. So Does this mean its self acquired property as per your answer? 

If the property was inherited by X vide a registered partition deed, then he becomes the absolute owner of  his share of property.

It will be considered as his self acquired property with clear and marketable title on his name.

In this situation neither his wife nor his children or anyone have any rights in the property neither they can object him to sell the property in favor of the prospective purchaser.

Therefore if at all they file any case in this regard, you may challenge the same properly as per law and on the basis of the registered sale deed in your favor and merits..
