As long as it was made and signed before Oct 2007 it is fine,,,unless rules have change. We had to register ours two years ago when Mum went into a home.
Thanks everyone. I checked, and it was signed in July 2007. No need to apply for registration yet; I just wondered if I needed to make a new one. I'm going to update my Living Will, so thought I could do them at the same time if necessary.
