Is surety bond required if probate order does not mention?

My mother won a probate case last month in Delhi. The court order does not mention anything about submitting a surety bond, but our lawyer is insisting that it is required. The order reads: Letter of Administration granted to the petitioner with the seal of this Court in the form set forth, subject to completion of requisite formalities such as: (a) furnishing court fees on the value of the subject property (b) exhibiting inventory and account within the prescribed period, as per Section 317 of the Indian Succession Act, 1925. The file is to be consigned to the record room after completion of all necessary compliance and due formalities.
