Property transfer on death of spouse

We have a property on my wife's name. My wife expired last year. She didn't create any will as such. Now I am trying of get the property on my name with no objection from my kids. But I was told that we will have to go to the court and do the procedure which will incur me legal charges and registration charges as per the new GR. Is this true? If yes, can somebody pass me the link of the GR so that I can read it. Thanks in advance.
