Section 1205. Contents of petition

 The petition shall briefly describe the
  fund or property with respect to which the proceeding  is  brought,  and
  the  nature  of  the action or proceeding which gave rise to the fund or
  property. It may include one or more items, as the attorney-general  may
  be  advised,  without  prejudice  to  his right subsequently to commence
  proceedings relating to other items not  included.  It  shall  also  set
  forth  the  facts  from  which  the  court  may  find,  or  from which a
  presumption may arise, that (a) the rightful owner or owners of the fund
  or property are unknown; or (b)  that  they  have  died  without  having
  disposed  thereof, and without having left a will, disposing thereof and
  without having left any heirs, next-of-kin or distributees; or (c)  that
  such property has been abandoned.
