Share rights in property whether legally safe

Dear Mr. Manivannan,

From the facts revealed by you, it appears that  the property in question seems to be the self-acquired property of your grandfather.  Either during his time, or after his death by means of inheritance it has been divided into 7 shares between 2 sons and 5 daughters.  According to you, your father thereafter obtained registered relinquishment deeds from three sisters.  Since the relinquishment deeds are all duly registered, you are legally safe.  [But I do not know whether any consideration i.e. amount paid by your father to his sisters has been mentioned in the relinquishment deed.  In that event, it cannot be a relinquishment deed rather a regular sale.]  However, if your father had separately paid the money and got the relinquishment deed separately without linking the payment that is a different matter.

Yes in your father's share you and your mother has got equal share.

You and your mother can share the 4/7th share of your father, if you both are the only legal heirs of your father.
