hello, I own a property in spain and have a couple of questions.
This was my main resident whilst living in spain I returned to uk in 2008 and now own a uk property, my questions are:

I did not realise I was liable to pay taxes in spain for owning a property there, what should I do, my last tax return in spain was for 2007.
secondly, should I be filling in these tax returns every year in spain or is it ok to just do this in the uk?

and finally, if i sell the spanish property which I lived in for a year before moving back to uk. where do i pay CGT, if i pay in spain, do I lose my right to the "private letting relief in uk? I am really confused, any help is very welcome, kind regards, susan
