Hi Claruickie, I had the same problem as you Thomas Cook kept telling me I need documents translating and apostilled etc and were even sending me the companies info where i needed to send my birth certificate, passports etc. It was going to work out at about £200 to get it done but my WC Jasmin was telling me no need. I researched it by scouring the internet which backed up what Jasmin was telling me. Basically, what is required varies between states and for Quintana Roo you only have to supply documents if you have been divorced, you were adopted or have changed your name for some reason. None of these applied to us so we didn't take anything. I think I drove Jasmin mad checking though...I must have asked her the same question about 4 times because I didn't want anything to get lost in translation, to get the wrong end of the stick and be in trouble when I got to the resort. A lot of the confusion is because the requirements are subject to change at anytime and actually changed earlier this year. Prior to this change you had to get translations etc which is why the travel agents are still recommending this.
