In my post 14 above I wrote that Mercer were insisting that it was an Irish Regulatory requirement to provide a birth certificate rather than a passport. I said that I was going to query this with the Pension Ombudsman which I did. Now it appears that the Tin God who gave me the above information was wrong and decided to check out the information after insisting that they were right.
This is their latest post on the matter.
"I have contacted our compliance colleagues who have confirmed that the requirement for a birth certificate is in fact a Mercer risk and compliance requirement rather than a regulatory requirement. Our requirement is designed to meet the Trustees obligations. There is a degree of flexibility and if you would like to contact us directly at
marketing.ireland@mercer.com, we can work with you to resolve this issue."
