Is this question really off-topic here? It was closed as off topic by John Conde.
The question might be subjective, well actually it is (at least the title, ehich was edited in btw). But if the OP would better write the question I think it would be a good fit here. The question is about the rules of selling an .eu domain which is webmasters related IMHO.
Especially when having this meta question in mind. One of the problems here on webmasters is the fact that there is a real issue of overlap (with SO, SF etc). This question would be a question which doesn't belong on those.
