Register of charges
All charges on the property of a company by way of mortgages, fixed or floating debentures, bills of sale, etc., must be registered with the Registrar of Companies. If not, they will be void and so not enforceable against liquidators or creditors. The company itself also keeps a register containing full details of each charge: the property, the persons involved and the amount of the charge. This must be kept at the offices of the company and must be open for inspection by members of the company and creditors at a fee. Certain charges must also be registered with the Land Registry.
