or you can do it like this? I could only find info from Donegal, but presumably the same applies nationwide?
Change of ownership - Person purchases vehicle, previous owner has lost VLC/VRC or person cannot locate previous owner.
For vehicles registered after 01/01/1993
New owner completes an affidavit which is in turn signed by a Commissioner of Oaths/Peace Commissioner/Practicing Solicitor, the person can send the form to the VRU, Shannon directly themselves or take the completed affidavit into the Motor Tax Office who will forward the form to Shannon (there is no necessity for an RF134 form to be completed nor is there a fee involved). Shannon will then update the Computer System with the new owners details and a new Vehicle Registration Certificate will issue to the new owner.
