If you obtain Turkish citizenship through marriage, then later divorce, your citizenship status will not be affected.
In the event you are considering marriage solely as a means of obtaining Turkish citizenship, however,
note that Turkish courts will not grant you a divorce on the basis of a 'fictitious marriage'.
Furthermore, you may be prosecuted by security authorities and the Census Directorate
(Nüfus Müdürlüğü) if they learn of your scheme. "
