Should I amend the sale deed before selling the property?

I hope all is well. I have a query regarding a sale deed. I own a flat, and the sale deed includes both my name and my mother’s name. I am the only child of my parents. Since both my father and mother have unfortunately passed away, I need to know if I should register an amended sale deed with the registrar, removing my mother’s name, before selling the flat. Or will the current sale deed, along with her death certificate, suffice when selling the property?
