How to retain the right in case of divorce with EEA National

Ok
Got married to an EEA member in Jan 2007, got the 5 year visa/residence document (using EEA1), in June 2007.

Things are not going too well just now, called the home office and found out that we should be married for 3 years before I can retain a right to stay here. Well a problem but not a big one, since we guys are planning an amicable divorce and would probably remain friends, so I can stretch it to 3 years, she would be concerned if I lost my right to live here.

Now what I wanted to know was, How do you apply for this who retaining the right thing?
Is there a form or something?
Also what happens at the end of 5 year period? What forms do I use? Would it still be EEA4, or will I have use the normal form for indefinite leave that you use after a 5 year period?
Is there any chance they can refuse me the right of retention?


Our 3 years will complete in Jan 2010 which apparently is closer then my cars next MOT, so we can workout things, but I need to know where I stand.


I would really appreciate help from people who know the procedure and related law, or those who have been through similar situation.

Thanks
