Wants to transfer father's flat on his name other brothers given NOC

My father left a flat (Pune City) to me (his daughter) and remaining property to his 2 sons. Both my brothers are in good terms with me and they have given a no objection letter to the provisions of the will so that I can transfer the flat in my name. Now to transfer the flat transferred in my name do I require a probate? My understanding is probate is not required to transfer the flat in my name in Pune City (Maharashtra) if all the legal heir in the will provide an affidavit that they do not have any object to the provision in the will. Is my understanding correct? Kindly guide me. Thanks,
