Prank in the process of probate

Prank in the process of probate I have been associated with my professor for the last fifteen years .After his demise ,I came to know through reliable sources that he had recommended my name alongwith the names of non biological children of his late married wife as dependent/heirs in his registered testament .When testamentary guardian/beneficiary approached to the court for probate ,dependents were not informed of any course of action taken by the court .Whole process was carried out in clandestine way .In this connection ,I urgently need forum's guidance ,insight view and suggestions how and where to proceed .
