Transferring of Property to Legal Heir

Have two brothers, one is older and other is older than me. Our father expired 20 years back and our mother just passed away two months back. At the time of death, my mother & I were the joint-owners of the property in which we are living currently. My mother’s name was registered as the first owner. At the time of purchase of this property, she made a WILL in my name where she willfully mentioned that I will be considered as legal heir of all her movable & immovable properties that she held at the time of her death. The WILL is registered. 1. In the above scenario, do I need to obtain separate N.O.C. or any kind of power of attorney from my two brothers to get the property transferred in my name? I was told by a lawyer practicing in the local sub-registrar office that there is a judgment/ruling/order of Honourable Supreme Court that even if in the presence of a registered WILL, one needs to take such N.O.C./P.O.W. from siblings to get property transferred in my favour. Is it true? If so, can I have the copy of this order etc. or its citation? 2. What is the procedure of transferring the property in my name if by the virtue of the WILL I am the legal heir of the said property with/without Honourable SC order etc.?
