We read what the requirements were abt 6 months b4 the ILR application was due to be sent. We realised we did not have too much in the way of evidence for the first 18 mnths of marriage, so it was panic time to get my wife's name on as many bills as possible for the last 6 months. Then we sat back and chilled out until 3 days b4 we had to send it. We spent all day putting everything together, which by the time we had finished was not too much really, then sent it by next day signed for. We also enclosed a pre-paid next day signed for return envelope, and 3 and a half to 4 weeks later everything was returned to us, except a letter written by my parents confirming we had in deed lived together for all our marriage. In fact in all that time we have only had 2 days when we haven't seen each other - and what a drama that was. lol

Good luck and dont worry about it too much, its a lot easier than getting the visa to get here !!
