Irish company statutory registers, resolutions and share records

Incorporation creates a public CRO record, but it also creates internal record-keeping duties. The company's statutory registers record its members, officers, ownership interests and other matters that cannot be reconstructed safely from a certificate of incorporation or a search result alone.

Accurate registers support annual returns, share transactions, bank onboarding, investment and due diligence. They should be updated when an event occurs, not recreated years later from memory.

Core registers and company books

The exact set depends on the company, but a routine private LTD commonly needs a register of members, directors and secretaries, directors' and secretaries' interests, minute books, share allotment and transfer records, and copies of key contracts or instruments required by company law. Charges and beneficial ownership have related but distinct records and filings.

The register of members is particularly important because it evidences legal membership. A cap-table spreadsheet is useful management information but should not be treated as a substitute for the statutory register and valid transaction documents.

  • Register of members and share movements.
  • Register of directors and secretaries.
  • Register of relevant officer interests.
  • Board and general-meeting minutes and resolutions.
  • Company seal, sealing and key contract records where applicable.

Public filing and internal records must agree

The CRO register does not replace the company's own books. An allotment, transfer, director change or registered-office move can involve board approval, internal register updates, certificates and one or more external filings. Completing only the visible online form can leave the legal record incomplete.

Before each annual return, reconcile the B1 particulars to the internal registers and the approved accounts. Resolve differences by checking the original transaction date and documents rather than simply changing the spreadsheet to match the public search.

Where the records are kept

CRO Form B3 is used to notify places where specified company records are kept, including the register of members, directors and secretaries, minutes and certain contracts. The form is relevant where the statutory location rules require notification of a place other than the registered office.

CRO guidance also explains inspection rights for members, officers and the public in relation to particular records. The company should know which records are inspectable, where they are held, who handles a request and how personal data is protected without obstructing a lawful inspection.

Update records at the transaction date

For a share transfer, preserve the instrument of transfer, approvals, consideration and tax analysis, then update the register and certificate position. For an allotment, document authority, issue terms and payment before filing Form B5. Officer changes should be reflected internally and notified to the CRO within the applicable deadline.

Written resolutions and electronic signing can be useful, but the company should retain final executed versions in a controlled repository. File names, access rights and backups are mundane until a bank, investor, liquidator or court asks for the record.

Run an annual company-secretarial review

At least annually, check the constitution, officers, members, share capital, RBO position, registered office, record locations, minutes, seal use and CRO filings. Compare each change made during the year with its approvals and effective date.

Frequently asked questions

Does the CRO keep an Irish company's statutory registers?

No. The CRO holds public filings, while the company must maintain its own statutory books and underlying transaction records.

Is a cap table the register of members?

Not automatically. A cap table is useful, but the statutory register of members has its own legal function and should be maintained from valid source documents.

What is CRO Form B3?

It notifies the CRO of places where specified company registers, minutes, contracts and other records are kept where the statutory notification rules apply.

Who is responsible for company records?

Directors have a duty to ensure Companies Act compliance. The secretary commonly administers the records, but appointing a provider does not remove the directors' responsibility.

When should registers be updated?

Update them when the underlying appointment, allotment, transfer, resolution or other event takes effect, alongside any required CRO or RBO filing.
