Irish company officers reviewing director and secretary records

Every Irish company must have a secretary. When that person or corporate secretary changes, the company should document the cessation and new appointment, protect access to statutory records and notify the CRO within the required period.

StartCompany.ie’s €100 change-of-secretary service provides filing support for a routine replacement. It can also connect the company with the separate nominee company secretary service where an ongoing appointment is needed.

Why the secretary role matters

The secretary supports statutory filings, records, meeting administration and the custody or controlled use of company documents. Directors remain responsible for ensuring the company complies, even when tasks are delegated to the secretary.

A vacancy or unsuitable appointment can disrupt annual returns, bank authority and access to the statutory books. The board should therefore plan the handover rather than treating the B10 as the whole change.

Approvals, eligibility and Form B10

Record the outgoing secretary’s effective date, approve the incoming appointment and obtain accurate particulars. The CRO requires notification of officer changes on Form B10 within 14 days.

For an LTD with one director, the sole director cannot also be secretary. A corporate secretary may be possible, but its details and authority must be correct.

  • Confirm the outgoing secretary’s cessation date.
  • Approve and obtain consent from the replacement.
  • Check the single-director LTD restriction.
  • File Form B10 within 14 days.
  • Transfer statutory records and filing access securely.

What StartCompany.ie needs

Provide the company number, current secretary details, replacement particulars, effective dates and the board’s intended approval route. The public filing must match the signed company records.

Our €100 service supports the change itself. It is separate from the annual nominee secretary appointment, annual return preparation and any repair of overdue filings.

Completing the handover

Collect the statutory registers, minutes, seal, filing credentials, tax correspondence and deadline calendar. Revoke or update third-party permissions where the outgoing secretary had access.

Review upcoming ARD, RBO and tax deadlines immediately after the change. A company can file the officer update correctly and still miss another obligation if the handover is incomplete.
