i know this is an old thread but wanted to give details of our situation.
we recieved letter from nib (front page, we notice we dont have your original policy... with 6 page of legaleese, requesting signatures and witness) in oct requesting original life assurance policy, we used nib as a broker for irish life policy. i rang the bank manager (different to that which we had dealt with) and tod them all had been provided to the prev manager. she said fine, she would look into it and get back to me if theres was anything futher needed.
i heard nothing until last week when i recieved an identical letter, and after a bit of back and forth with nib and il, it was discovered that it was a "block policy"??? and therefore everything was ok.
i got a letter from nib this morning confirming that it was a block policy and all documentation was in order.
not sure what the block pokicy is, but it might be a question to ask if the same happens to you?!?
