Spouse Leave to Remain Application Help

Hi,

My wife is a British Citizen and I'm currently on a Tier 4(Student visa), we've both being living together with her parents in their house since November 2009 until now and I'm planning on switching to a spouse visa. She's on a salary of 1100 pounds a month after tax and we don't pay rent or utility bills. We have a joint savings account totalling just under 1200 pounds. I had previously being on IGS and worked as an IT consultant for 1 year and haven't worked since I got on a student visa September last year. My questions is:

Besides 3 months worth of bank statements and payslips for all our accounts, what other documents or information would I need to produce during the application process? I have an appointment to make my application at a public enquiry office in a week's time.

Any help appreciated!

Thanks

If you're applying in person you'll need to show proof that you are attending your studies. Check form FLR(M) for other documents.
You're both over 21?

Yes we are!

Thanks
