I think the different institutions have different requirements. Some will do it internally - some externally i.e. with a solicitor involved. All will require a Family Law Declaration to be completed - even if done internally.
I think that ptsb do often require not only a top up but also an entirely new charge/ mortgage to be created.
I think that the lending institutions can be entirely disingenuous also with their customers i.e. oh, even if you need a solicitor, it will only be 40/50 euro!!! Thats fine if I'm just being asked to have a client swear a Family Law Declaration but not if I'm being sent a full set of mortgage documentation, a list of special conditions and I have to take up Deeds as well.
Ask the question of the lending institution - what is involved here? Why do I need a solicitor?
