You will be presented with a Total View of the details you have entered for review. From this screen click on Check Form to ensure all the necessary information has been entered. If any required information has been omitted, you are now prompted to enter the missing text.

Step 7 - Print & sign signature page

Once the Submit button is clicked, a signature page will be generated, which you will have to print and sign. The signature page should be sent to the CRO for registration along with any other necessary documentation. A filing fee of €20 is required (this is cheaper than completing a paper application, which costs €40 to file as it involves a longer registration process).

Alternatively, it is also possible to pay for the business name online using CORE. Please remember that when the application is made online, the signature page (and fee if necessary) still needs to be submitted to the CRO for registration. Increasingly, payments are being made by credit card but customers are not submitting the relevant signature page. The certificate cannot be created without the submission of this document.

Your Workspace

The registration page and the document are available in your workspace for future reference. A copy of the signature page can be printed from here if you had any difficulty through the earlier process.

If the document is returned to you for any reason, you will be able to edit it in your workspace by clicking on the edit & resubmit icon. You will need to generate a new signature page if you make changes to the form. The document is only deemed legally received in the CRO when the signature page and fee are received.
