ok I got it. Same applies here. There are some agreements which must be
set up in written in Turkish Law either. Lease of real estate can be in
verbal but Sale of real estate or traffic vehicles must be conducted in
written form. As for money transaction agreements, they are not
necessarily set up in written form, but we have a law which requires that
in court you have to prove this transiction with written agreements if
their limit is over approximately 400 US dollars. So practically they are
established in written form as well. Marriage agreement and tastaments
should be conducted in written form too.

As you see types of these agreements vary quite much, therefore there is
no "one" act covering all these cases like your "Statute of Frauds". These
rules are decreed in various relevant acts.

What you are mistaken is your opinion about Islamic Influence to Turkish
law. This is not true. In Turkish Law system there is NO influence or
resemblance from any type of Islamic law practices. Islamic law is
abrogated in 1925 just after the founding of Turkish Republic and secular
law adopted from European Law (mostly from Switzerland, Germany,
France and Italy) came into force then. Recent Turkish Law system is
totally secular and a mixture of mainland European countries law systems.
As I said this subject is established in many laws but you'll find the most
important key points in "Borclar Kanunu" (=Turkish Agreement Act) which
is nearly the same of Switzerland's relevant act.

Hope this helps.
