Under the Indian Trusts Act, 1882, the copy of a trustee's petition to Court shall be served to:

Section 34 says a copy of the petition "shall be served upon, and the hearing thereof may be attended by, such of the persons interested in the application as the Court thinks fit". Service is left to the Court's choice, so it need not go to every beneficiary, and neither the author of the trust nor the Advocate-General is named.
