The protection period continues during the lifetime of the owner of the work and for 70 years after his death.
For works published after the death of their owner, the protection period is 70 years after the date of death.
In cases stated in the first paragraph of article 12, the protection period is 70 years from the date that the work is published, unless the owner of the work discloses his name before the expiry of this period.
In case the first owner of the work is a legal person, the protection period is 70 years from the date that the work is published.
Article 11 ("IN WORKS WHERE THE NAME OF THE OWNER IS STATED")
The person using his name or his known pseudonym in the published copies of a work or in the original of a work of fine arts as the owner of such a work is considered as the owner of the said work until otherwise is proven.
(Amended: 7.6.1995—4410/5) The person regularly presented as the owner of the work in public places or in the conferences and performances broadcast by radio-television is considered as the owner of the said work; unless another person is considered as the owner of the work by way of the inference set forth in the first paragraph.)
Article 12 ("IN WORKS WHERE THE NAME OF THE OWNER IS NOT STATED")
If the owner of a published work is not known per article 11, the publisher, and in case the publisher is also not known, the duplicator may exercise the rights and authorities as the owner of the work in his own name.
Such authorities belong to the deliverer of the conference or the executor of the performance in cases where the owner of the work is not known by inference in the second paragraph of article 11.
The provisions of ordinary proxy are applied in the relations between the persons authorized under this article and the original owners of the right.
Article 47 ("Expropriation")
The authority to make use of the financial rights on a work that is deemed to carry importance for the country culture may be expropriated by way of paying a suitable value before the expiry of the protection period through a decree. In order to decide on this matter, the work should have been promulgated in Turkey or by Turkish citizens out of Turkey and at the same time the copies of the work should have been sold out for two years and the promulgation of new copies by the owner of the rights within a suitable period should have been considered impossible.
