Ok, I have tried to figure out the Property Registration Authority website. Searching the Registration online, it seems the house, although clearly shown on the map, is not registered. So, a search using Form 11 is required with a fee of €20. That would be no problem but I can't download the form without installing Adobe Reader but it's a free trial and I don't want to give my payment details and then perhaps default into a payment later. I have called the solicitors office and asked them to check their file but, in the meantime, I want to complete the SA form for Revenue. Does it matter if I put 'Tenants in Common' on the form but it later transpires that they are 'Joint Tenants'
TL;DR What difference does JT versus TIC make to the Revenue and their form?
