Retain Rights of Residence - EEA

[bobobo]

I have moved this post under the right heading "Immigration for Family Members"...I apologise for the oversight

Hello All,
I have a query that I needed to confirm. Basically I was married to my wife who is an EEA national, I was married for 3 years before we filed for divorce. We have been living togethor in the UK for all of this period. She and I have been working throughout. I have letters and other proof of us co-habiting for the last 2 years +. She has agreed to co-operate and give me her EEA Resident card (green in colour) as a form of Id. She is applying for her PR at the same time, so her passport will be with the HO. My questions are:

1. The EEA resident card has expired now, would that be an issue for the home office, would they still consider this as a valid ID? (the card expired about 3-4 months back)
2. She might not give me her passport, as she has moved on and doesnt want that I should bother her any more.Would me submitting the proof of co-habiting and the Resident card be ample proof for me to retain my Rights of Residence?
3. I am not sending my Passport at this point in time as I need to travel frequently on work and sending my passport can be a show stopper. Bit would send it once I am asked to submit the passport.
4. I do have a letter from her employer confirming that she was working during and over the period of the divorce as well, so that should count for something as well.
5. Also does anyone know of a good immigration lawyer I can consult to smoothen out the whole process.

Thanks in advance for all your help and valuable advise. I am sure anything would be helpful at this point in time.

Cheers!
Bob
