Nelly we did a joint statement as part of our history of relationship section (with relevant dates bolded), and an individual one each. Just typed and printed. Starting with I,.... Of 11 blah blah street, make this statement etc etc (now i cant remember actually) but there is a really good stat dec kind of outline sample on the diac website in a pdf (search for it) also ive commented on a very informative thread about someone elses application (granted in a week) and i think he was the one who put me onto that outline/sample. Which i didnt bother to write in but used as the basis for ours.
Maybe search for posts ive made if you dont already nwo the thread im talking about - he included an amazing contents page.
(hope this makes sense sorry im a bit hungover from NYE!)
