Companies are obliged to make up the register of debenture holders when debentures are issued. If the company has tradable debt it will usually be a condition of the loan instrument that the company keep a register of debenture holders.
It can be kept at the registered office or where it is made up. If not at the registered office, the company must notify the location to the registrar of companies. Debenture holders and members can inspect this register free of charge; other may have to pay a fee up to the permitted maximum.
On request copies of entries must be sent within ten days with maximum fees as for the register of members.
