Have you organised a mortgage? That can be quite tortuous.
"As 2 live abroad and never owned property in Ireland, will they be liable for stamp duty! "
If they are the purchasers, they can hardly say they intend to live in it! And if they are the vendors, it does not apply.
"Do , we, the purchasers have to lodge the money with solicitor or can it just be given to the other 3 directly!"
Well, I would not recommend doing this without the solicitor! You need to make sure that there is an actual formal completion when money is paid over in exchange for signed paperwork. Otherwise, its the kind of things where years later, everyones wondering what dd actually happen.
