Registration of charges required for enforceability; unregistered charges not recognized by liquidators or creditors unless a certificate is issued. Companies must register particulars and instruments of any charge, signed by the company and charge-holder, with the Registrar within thirty days, subject to a Registrar-granted extension up to three hundred days on payment of additional fees and further extension under section 87 if needed. The Registrar issues a certificate of registration when a charge is registered. A charge will not be taken into account by a liquidator or other creditor unless duly registered and a certificate issued, without prejudice to contractual obligations for repayment of the secured money.
