"The bank transferred mortgage to our solicitors bank account"
I have said this before, but it is worth saying again anyway: the loan cheque is a far better way of dealing with a mortgage, particularly if it is with BOI, AIB, EBS or any of the other lenders who only charge interest from when the cheque is cashed. The solicitor can get the cheque a few days ahead of when it is needed, and the client only pays interest from the day they take the keys.
There are security issues with loan cheques going astray in the post, but this is easily solved by having them issued from\collected at the local branch (as I think happens with NIB - though I think they charge interest from date of issue; open to correction on this)
