  18.Place of
  
  institution of suit where local limits of jurisdiction of Courts are
  
  uncertain.-
  (1) Where it is
  
  alleged to be uncertain within the local limits of the jurisdiction of which of
  
  two or more Courts any immovable property is situate, any one of those Courts
  
  may, if satisfied that there is ground for the alleged uncertainty, record a
  
  statement to that effect, and thereupon proceed to entertain and dispose of any
  
  suit relating to that property, and its decree in the suit shall have the same
  
  effect as the property were situate within the local limits of its
  
  jurisdiction:
  Provided  that the suit is one with respect to which the Court competent as
  
  regards the nature and value of the suit to exercise jurisdiction.
  (2) Where a statement has
  
  not been recorded under sub-section (1), and an objection is taken before an
  
  Appellate or Revisional Court at a decree or order in a suit relating to such
  
  property was made by a Court not having jurisdiction where the property is
  
  situate, the Appellate or Revisional Court shall not allow the objection unless
  
  in its opinion there was, at the time of the institution of the suit no
  
  reasonable ground for uncertainty as to the Court having jurisdiction with
  
  respect thereto and there has been a consequent failure of Justice.
