Fictional director feeding a sample registered-office evidence document into a scanner to prepare an address-query response

Your Irish company application or registered-office change has reached the CRO, but a message asks for evidence of the address. Should you send a utility bill, a lease or your address-provider invoice? Start with what the message actually requests, not a document list copied from a different company's case.

This guide concerns evidence of the company's registered office under section 50A of the Companies Act 2014. It is distinct from a director's proof of residential address, a provider's identity checks or Revenue's assessment of a trading location. Official sources were checked on 10 November 2026. The preparation suggestions and fictional examples below are not a universal CRO attachment list or a guarantee that particular evidence will be accepted. This is general information, not legal advice on a disputed address or notice.

1. Understand what section 50A changes

Section 50A covers evidence needed for incorporation and for recording a registered-office change under section 50(3). The revised Act records its insertion with effect from 3 December 2024. It gives the Registrar an evidence-request power; it does not prescribe one standard bundle that every company must always attach.

Save the complete request and the relevant submission reference. Identify whether the issue concerns a new company's proposed address, an existing company's address change, or another issue mentioned alongside it. Record the requested evidence, response instructions and any stated deadline. A heading saying returned or queried does not tell you the full reason.

Ask the presenter to explain unclear wording before commissioning documents. In particular, establish whether the CRO wants clarification of the location, the company's connection to it, an agent arrangement or a discrepancy in the filing. If several corrections are requested, keep them on one action list rather than assuming address evidence resolves the whole application.

2. Establish which address you are proving

The CRO requires a physical registered-office location in the State, not just a PO box. Its guidance explains the need for postal and hand delivery and access to certain company records. An attractive address label or a website showing a building is not evidence that the particular company can use that location.

Compare the address in the request with the submitted A1 or B2, your provider's allocation and the underlying supporting records. Check the building, unit, street and other relevant details consistently. Where two descriptions refer to the same premises, explain the relationship with supporting information instead of silently changing one document to resemble another.

Keep personal and company evidence separate. A director may live somewhere different from the company's registered office. Conversely, if a home is genuinely used as the office, explain that actual arrangement rather than assuming a personal bill answers every question about company use. Do not send a passport merely because someone asked for evidence of premises.

3. Build an evidence map, not a random bundle

Create a short index matching each point in the CRO request to the evidence you propose to provide. For premises used directly, ask the presenter whether relevant occupancy records, permission or an explanation of the company arrangement are needed. For an address service, ask the provider what company-specific confirmation it can properly supply. These are preparation options, not representations that the CRO demands or accepts any particular document.

A receipt may establish that somebody paid for a service without establishing activation, the allocated address or the period during which this company may use it. Similarly, a document naming a director, another group company or a former business needs an explanation of the connection. More pages do not necessarily answer a missing link.

Use the table to identify questions for the presenter. Where evidence is absent, say so and agree the next step. Do not backdate permission, edit another company's name into an agreement or manufacture an address history to make the file appear complete.

4. Confirm a third-party address and any ROA arrangement

Where an approved Registered Office Agent arrangement is used, CRO guidance describes company consent and the agent's name, number and address on the relevant A1 or B2. Check the actual arrangement with the presenter. An ordinary commercial supplier's contact address is not automatically the agent information required for a filing.

Ask your provider to confirm the exact company or proposed name covered, the allocated address, when use is authorised and who can answer the evidence query. If the company is still being formed, make clear that there is no issued CRO company number yet. Do not borrow another customer's agreement or invent a number to complete a template.

StartCompany.ie works with authorised partners to provide its services. That is not a claim that StartCompany.ie itself is a CRO-approved Registered Office Agent. Confirm who supplies the address and any relevant agent particulars through the service process. A provider's onboarding checks and the Registrar's evidence request are separate tasks; completion of one is not proof the other has been satisfied.

5. Treat incorporation and an existing-company move differently

For a new company, the registered office is among the particulars supplied on Form A1. Work with the incorporation presenter on the same application and current query. Do not treat a proposed company name, an address order or an application receipt as evidence that incorporation has been completed.

For an existing company, section 50 requires notification of a registered-office change within 14 days of the change, subject to section 50A. The CRO says a B2 change becomes legally effective only when it registers the form. A submitted or queried B2 should therefore not be described as a completed register update.

Keep the office and correspondence arrangements under review while the issue is resolved. Section 51 addresses service at the address recorded by the Registrar even where the office has changed. Do not assume a pending replacement or evidence response redirects notices or restarts a legal deadline. Preserve urgent correspondence and seek appropriate advice on the document concerned.

6. Prepare a readable response with one responsible presenter

Nominate one person to coordinate the reply. Give them the full CRO message, the filed version, the address confirmation and a list of missing items. If a provider and an accountant are both helping, agree who obtains evidence and who actually sends it. Avoid parallel replies containing different address versions or incomplete attachments.

Use a brief covering explanation: identify the submission, restate the particular point being answered and list the relevant documents. Explain genuine differences in company name or address descriptions rather than expecting the reviewer to infer them. Check that scans are complete, readable and in the format requested, with all relevant pages and dates visible.

Follow the route in the query and retain the response and acknowledgement. If a requested document cannot be obtained, ask promptly what clarification or alternative is appropriate; do not assume your preferred substitute will suffice. CRO guidance notes that incorporation documents returned for correction are processed by resubmission date, so avoid promises based on the original filing date.

7. Two fictional evidence-response examples

Example A: a founder proposes to use a home address. The application gives one unit description while the available premises record uses another. Rather than sending every household document, the founder asks the presenter what the query requires, obtains the relevant explanation and checks the actual permission arrangements. The response connects the proposed company and the correct location without pretending the director's residential evidence is automatically conclusive.

Example B: an existing consultancy orders an address service and files a B2 before the provider has confirmed allocation. When an evidence request arrives, the director finds that the payment receipt does not identify an activated company-specific address. The director contacts the provider and presenter, resolves the permitted address and dates, then answers the query using the instructed process. The order is not represented as retrospective approval.

Neither example predicts acceptance or describes an actual StartCompany.ie customer. They show two different information gaps: inconsistent location evidence and an unconfirmed service arrangement. If the address itself cannot lawfully or practically be used, buying more copies of the same paperwork is not the solution. Obtain advice on the correct filing position.

8. Protect personal information without obscuring the answer

The Data Protection Commission identifies data minimisation, accuracy, integrity and confidentiality among the core data-protection principles. Apply them when assembling a premises pack that may contain other people's details. Ask what is necessary, which documents are supporting evidence and how they should be delivered securely.

Do not email an entire personal-finance folder, unrelated identity documents or another tenant's information merely to show cooperation. At the same time, do not redact the very name, location, date or authority needed to answer the request. Discuss proposed redactions with the presenter and, where necessary, clarify the CRO's requirements before submitting.

Confirm how the evidence will be handled and whether any document forms part of a publicly inspectable filing. Do not assume that an attachment is private because you sent it as supporting material. Keep the company's necessary response record with appropriate access controls, rather than leaving sensitive duplicates in multiple informal inboxes.

9. Choose address provision and query support separately

If you need a suitable replacement or formation address, review StartCompany.ie's Registered Office Address service. It covers 12 months, with company review, required checks and confirmation of the allocated address before use. Receipt and forwarding of official CRO and Revenue correspondence follow the agreed terms. Renewal is arranged separately; the checkout does not create an automatic subscription.

Address provision is not automatically management of an existing CRO evidence query. Before ordering, share the non-sensitive outline of the issue and ask whether the proposed arrangement can assist. Confirm which evidence can be supplied, who liaises with the presenter, the service dates, any separate work and the total payable. Do not assume a routine address order includes legal advice or a reply to every outstanding submission query.

Form B2 filing assistance is a separate service. The address product does not include office rental, general parcel handling or annual-return filing. A purchase cannot guarantee CRO acceptance or a completion date, establish an operating presence for tax purposes, or guarantee banking or immigration outcomes. For an urgent or disputed situation, obtain the necessary professional advice alongside any address service.

  • Save the request, reference, instructions and any deadline.
  • Identify the applicant, precise location and relevant dates.
  • Map each requested point to relevant evidence and explain inconsistencies.
  • Confirm permission, allocation and any approved-agent particulars.
  • Agree the secure delivery route, presenter and response scope.
  • Keep submission evidence and verify the eventual CRO outcome separately.

Frequently asked questions

Can the CRO ask for proof of a registered office?

Yes. Section 50A provides an evidence-request power in connection with incorporation and recording a registered-office change. It also prevents the relevant registration step from being completed unless the requested evidence is provided.

Must every company attach a lease or utility bill?

Section 50A does not specify one universal attachment list. Read the actual request and confirm what evidence addresses it. The preparation options in this guide are not a statement that a particular lease, bill or letter will always be required or accepted.

Is my director proof of address enough?

Not automatically. The director's residence and the company's registered-office arrangement are different questions. Explain the connection where relevant and follow the request rather than substituting personal identity evidence for premises evidence.

Does paying for an address prove it is ready to use?

No automatic conclusion follows from payment. Obtain company-specific allocation and permission, check the service dates and complete the provider's process. An invoice may show payment without establishing the address arrangement needed for the query.

Is a queried B2 already an effective address change?

The CRO says a registered-office change becomes legally effective only when it registers the form. Check the recorded address and outcome rather than treating an instruction, payment receipt or submission acknowledgement as registration.

How many days do I have to answer an evidence request?

Use the instructions and any deadline in your actual request. This guide gives no universal response period for a section 50A query. The separate 14-day change-notification rule should not be confused with an assumed time limit for answering evidence questions.

Will an address order include replying to my CRO query?

Not automatically. Confirm the address service, available supporting confirmation, any separate query or filing work, responsible presenter and total payable before ordering. Neither the purchase nor an evidence checklist guarantees acceptance.

Confirm the address arrangement before filing

Review the Registered Office Address service, then confirm allocation, supporting confirmation, any separate CRO-query work and the total payable before ordering.
