  (1) Subject to the provisions of this Part,
  
  every charge created on or after the 1st day of April, 1914, by a company and
  
  being a charge to which this section applies shall, so far as any security on
  
  the company's property or undertaking is conferred thereby, be void against the
  
  liquidator and any creditor of the company, unless the prescribed particulars
  
  of the charge, together with the instrument, if any, by which the charge is
  
  created or evidenced, or a copy thereof verified in the prescribed manner, are
  
  filed with the Registrar for registration in the manner required by this Act
  
  within thirty days after the date of its creation :
  Provided  that the Registrar may allow the
  
  particulars and instrument or copy as aforesaid to be filed within thirty days
  
  next following the expiry of the said period of thirty days on payment of such
  
  additional fee not exceeding ten times the amount of fee specified in Schedule
  
  X as the Registrar may determine, if the company satisfies the Registrar that
  
  it had sufficient cause for not filing the particulars and instrument or copy
  
  within that period.
  (2) Nothing in sub-section (1) shall prejudice
  
  any contract or obligation for the repayment of the money secured by the

  (5) In the case of a charge created out of

  the date on which the instrument creating or evidencing the charge or a copy
  
  thereof could, in due course of post and if dispatched with due diligence, have
  
  been received in India, shall be substituted for thirty days after the date of
  
  the creation of the charge, as the time within which the particulars and
  
  instrument or copy are to be filed with the Registrar.
  (6) Where a charge is created in India but
  
  comprises property outside India, the instrument creating or purporting to
  
  create the charge under this section or a copy thereof verified in the
  
  prescribed manner, may be filed for registration, notwithstanding that further
  
  proceedings may be necessary to make the charge valid or effectual according to
  
  the law of the country in which the property is situate.
  (7) Where a negotiable instrument has been
  
  given to secure the payment of any book debts of a company, the deposit of the

  the purposes of this section, be treated as a charge on those book debts.
  (8) The holding of debentures entitling the
  
  holder to a charge on immovable property shall not, for the purposes of this
  
  section, be deemed to be an interest in immovable property.
