Having 2 domain names pointing to the same content is the worst of all the options.

If they want to pay the bill, I will happily offer some SEO consulting about this. The free advice is to keep the existing site with its existing content - it converts so why break it?

Just gone to look at both sites and see that the first domain is no longer resolving to any hosting, so I guess the decision has already been made. The second site is duplicating the first.

What more can be said?

Clients do this sort of thing and there is not much that can be done about it, especially if the site is now being handled by someone else. It is just a bit confusing because the author meta for both sites is the same.
