My initial raction was Yeah Right, As If, In Your Dreams. But then I read the Revenue notes and technically she could be considered a FTB. She did not build or purchase. And she has now inherited a one half share. The gift into joint names must have occurred before June 2000.
However, if she wants to rely on this, my view would be that she should have any Deed adjudicated and completely disclose all the circumstances to Revenue. That way she can make her case and if she succeeds, grand and if she loses, no harm done and there will be no worry down the line of interest and penalties.
Interesting.
