As far as I know, there is no internet website (in any language) dedicated
to Turkish Divorce Law System. If I were you, I would tabulate my
questions and ask them in this forum. Especially if you can ask them in
Turkish in the "Hukuk Sorulari Alani" I am sure you'll get most the answers
you need. Of course provided that you can understand or write in Turkish!
If this is not the case, then please ask them in English in this board.
