- As per Supreme Court , except a registered Sale deed , no other property document is valid for transferring the property in the name of buyer.
- Further, the said hand written and notarized document cannot be considered as a title deed of the property.
- Hence, legally said property is till date in the name of your grandmother and not the purchaser.
- Further, after the death of your grandmother , her property would be devolved upon her all the legal heirs equally , and hence the consent & approval by all is mandatory to make the said purchaser as owner of the property.
- Further, your father only cannot give any approval for the payment received by her.
- If your father is only surviving legal heirs then he can execute Sale deed in favour of the buyer after paying the current value of the property stamp papers.
