One wonders how the solicitor was hired. But solicitors are legal, not financial. Article says:ven in 2003, the late middle ages, the sellers of financial products did have certain obligations towards their customers. While this woman did take independent legal advice, that's not the same thing as financial advice.
So what “advice” the solicitor provided, I have no idea. I can see them saying they advised only on the legal and contractual issues rather than the wisdom of taking the loan but that seems a very narrow and unhelpful interpretation of their role.
So if the legal advice was, you can borrow this money, the interest rate is this, do you understand that, that could be it.
It was easy enough in the Wild West of that Ireland to get anyone to sign anything for you. I'd imagine an easy fee and bob's your uncle.
