Thank you for your replies.
I am not 100% sure the exact amount of the land registry fee - I assume it is between €200-400. And you are correct elcato, it is most definitely not worth stalling the sale over.
Then again I assumed that it was taken as obvious that the solicitor would be paying the fee seeing as how it was their mistake & we already paid for it.
That's why I wanted to make sure that I am not missing anything that states we should pay regardless of who makes the mistake.
Thanks very much for your replies - i will be onto the solicitor next to state that we will not be paying & take it form there.
Thanks.
