I'm getting a bit confused. I want to change my title to Ms but I'm not entirely sure how to go about it. I had thought it would be quite a straight-forward process but I was reading on the f-word Ms: is it really so difficult?! and realised I may be about to walk into a world of annoyance. My passport is due for renewal, can I just change my title when I send off my new one then use it as 'proof' for banks etc?
