What Form B10 is used for
The CRO describes Form B10 as the filing used to notify the appointment of an officer after incorporation, the cessation of an officer’s appointment and changes in particulars such as a name or address. The form can therefore represent several different events, not only the appointment of a new director.
The filing is part of the company’s statutory record. It should be read as a dated register event: who changed, what changed, when it took effect and when the company notified the CRO. A B10 does not by itself describe the business reason, a change in ownership or the quality of the company’s management.
The 14-day notification rule
Current CRO guidance states that changes in director or secretary details should be notified within 14 days of the change occurring. This includes appointments and cessations as well as certain changes to particulars. The company is responsible for making the relevant notification through CORE.
When reviewing a filing history, compare the effective date with the registration or filing date where both are available. A delay may be a compliance signal, but dates can also reflect processing and record conventions. Avoid treating a date difference alone as proof of misconduct; use it to decide what needs clarification.
- Appointment after incorporation
- Resignation, removal or death
- Change of name or other particulars
- Secretary appointment or cessation
- Alternate or substitute officer events
How to read appointments and cessations together
An appointment shows that a person was notified as an officer from a stated point. A cessation shows that the appointment ended or was notified as ending. The current officer list is a snapshot; the filing history is the sequence. Reviewing both prevents the common mistake of assuming that a former officer remains current or that a current officer has always held the role.
Pay attention to clusters. Several B10s around an acquisition, address change, company name change or new financing event may reflect a normal reorganisation. The same pattern close to a large contract or payment request may justify additional questions about authority and the legal counterparty.
Important limits of a B10 search
A B10 is not a share register, beneficial ownership declaration, credit report or background check. It does not prove that a person controls the company, owns its assets or is authorised to give every instruction. Director information is one part of a company verification process.
The CRO also notes statutory requirements around minimum officers and secretaries. If a proposed cessation would leave the company below the required structure, the filing may be returned or require a replacement notification. This is one reason a missing or delayed event should be checked against the current record rather than guessed at.
Use B10 history in a practical due-diligence file
For supplier onboarding, investment, lending or a significant contract, record the company number, current officers, recent B10 events and the date you checked them. Compare the person signing your documents with the company information, while remembering that signing authority can depend on the company’s arrangements and the transaction itself.
CompanyReports.ie can make the timeline easier to review by bringing public company information into a readable profile and report. Preserve the report date and ask the counterparty to explain material changes rather than assuming that every appointment or resignation is either positive or negative.
