Dear Konuk;
According to the İnternatinal Private Law Art.14:
If parties are from different nations, the domicile law will be applied to the case, and if there isn't a mutual domicile, Turkish Law will be applied.
And according to Turkish Procedure Law, the competent court is plaintiff's domicile court or the court where the parties had stayed last six months.
As you see, you can bring him on the court in Turkey.
But your law suit should be supported by the witnesses.
Finally, you should call upon a lawyer.
Regards
