Thanks Iain, thats really helpful. You probably won't know this (as you're a man) but I'll ask anyway incase anyone would know.

Will I need a copy of my first marriage certificate because my birth certificate and decree absolute are in different last names, my birth certificate is my maiden name my decree absolute is in my married name, I have reverted abck to my maiden name so my passport and everything for the last 10-12 years is in my maiden name. Will this cause a problem??
