Rules on display of company name

During company secretarial checks I often uncover confusion in relation to rules on display of company name. The CRO’s rules are listed below and there very clear on this matter:

A company is required to paint or affix its name in a conspicuous place, in legible letters, on the outside of every office or place in which its business is carried on. A company is further required to have its name mentioned in legible characters in all business letters of the company and in all cheques, invoices and receipts of the company. A fine may be imposed on the company and on any officer in default for breach of the foregoing. If an officer of a company issues or authorises the issue of any business letter of the company or signs a cheque or order for goods, and the name of the company is not mentioned in legible characters, that officer is liable to be fined and will also be personally liable unless the amount due on foot of the cheque or order for goods is paid by the company.
