dear konuk (UK divorce recognition in turkey)
Actually,you need to consider this after the divorce decision. In fact, I would recommend you to sue him in Turkey if you have ask me due to it is easier an less expensive to sue a Turkish man in Turkey. When you get the decision in Uk then you need to make the decision to be recognized by a Turkish Court.It means you need to sue him again however the proceedings will be quite easy and fast in this case.
When I was living in the UK I did lots of these types of works and came to Turkey from the UK to end up the cases. I is not a hard work for a lawyer. Do not worry...
