Dont want to sound pessimistic but if my Fiances Fiance Visa is not approved, what is the first thing I should do?

If I appeal, how do I do it? if they refuse her visa they will give her the passport back along with all the original documents, then does my Fiance have to send me all the original documents back to me and I have the solictor fill in the appeal form and then send the original documents along with the appeal form to the court house?

Some people keep saying to me "ohh just wait to find out first" but I want to atleast have an idea what I need to do now as I know I would Panic if she is refused but if I know what I need to do now then I wont be panicing (as much)

Hope someone can help,

Bless you all!!!
