Requirements for registering an Irish unlimited company
The Irish unlimited company may be set up by only one member (this type of company does not have shareholders). However, it is necessary to appoint two directors, who must be natural persons. At the same time, it is also necessary to appoint a company secretary, which can be represented by one of the company’s directors. Our team of Irish company formation agents can offer more details on the duties of the directors of an unlimited company.
The company registration in Ireland for this business form requires drawing up the statutory documents, which, following the regulations of the new Companies Act, are now represented by the Constitution.
The company has to be registered with the Companies Registration Office (CRO), a procedure that can take approximately five working days.

The procedure to register an Irish unlimited company is the same as for any other business form. The following documents must be registered with the Companies Registration Office in this sense:

The designated unlimited company in Ireland
An unlimited company can take the form of a designated entity whose members are:
- companies limited by shares;
- companies limited by guarantee;
- partnerships.
It is also possible for the designated company to be registered as an Irish subsidiary of an enterprise registered abroad. This is often the case with EU businesses seeking to operate in Ireland.
The main differences between unlimited companies in Ireland
If you do not know how to choose between the different forms of the Irish unlimited company, especially when it comes to the share capital requirements, you should know that there is no specific amount to be deposited in the case of those with a share capital.
The only condition set out in the Companies Act is that private and public unlimited companies with a share capital must provide for the amount subscribed and its division into shares in the Memorandum and Articles of Association. As such, you are not bound to deposit a specific amount; however, it must be sufficient to cover the business’ operations.
