Dear Anita Ozer
If you get divorced in a Turkish Court the court will help you find your husband's properties.
But you have to claim this from the court and help them find it.
Since there is not a network between the land registry offices ,you have to ask for the possible land registry offices.
For example since you have got married in Ankara it's possible that your husband may have properties or bank accounts in Ankara
since this is a complicated issue to find his properties I suggest you to hire a lawyer in Turkey.
