Dear Shailesh,
Thank you for your query! I am Aadil and I will try to answer your question.
The short answer to your question is NO. You need not amend the sale deed.
A sale deed is a legal record or document that is used to certify the sale or transfer of a property from the seller to the buyer. It is a valid piece of evidence that can be used to assert ownership over the property and is also necessary for further sale of the said property. The laws and regulations regarding the sale deed are mentioned in the Registration Act, 1908.
It is possible for two or more people to combine their resources and buy a common property under one sale deed. They will be the co-owners of said property once the transaction is complete. Unless the co-owners have created a written agreement that states the share each party will have on the property, the shares of each party will be proportional to the amount of money they had put in for the purchase of this property. If during such a scenario of co-ownership one of the co-owners passes away, their share of the property passes on to their legal heirs or to some other person as specified in their will.
The Hindu Succession Act, 1956, describes in detail on who may be the legal heir to a person dying intestate. As per section 8 of the same, the son is a Class I legal heir to a male dying intestate.
Therefore, since your father died intestate, the ownership of said property has automatically been transferred to you and does not require any additional amends to the sale deed.
I hope this helps. Thank you for your time and patience!

Aadil
