If you are living in Turkey you need to go to the Nearest british consulate which in your case would be izmir, and get your bans put up ......dont remember the cost im affraid but they have to be up for 21 days then you will obtain your CONI (cert of non impediment).If you go on the Brit COns website it has all the relevant info. Where about are you planning on getting married? I can reccomend an excellent photographer not far from bodrum.
