The adulthood age according to Turkish civil code is 18 in ordinary.

But a person is also considered as an adult by Turksh law if he/she marries before 18 years old(as i said, the legal marriage age is 17).

A person can be rendered as an adult by the disicion of the court even if he/she is not 18 yet. Three conditions are required for being rendered as an adult by the court: 1)To have been filled 15 years old 2)The will of the person(who wants to be rendered adult) 3)The approval of his/her conservator(parent).

(I think the adulthood age was added after the topic had been opened. Otherwise i would have answered while giving the answer to the question about legal marriage age). I hope i could help sufficiently
