Article III

Any Contracting State which, under its domestic law, requires as a condition of copyright, compliance with formalities such as deposit, registration, notice, notarial certificates, payment of fees or manufacture or publication in that Contracting State, shall regard these requirements as satisfied with respect to all works protected in accordance with this Convention and first published outside its territory and the author of which is not one of its nationals, if from the time of the first publication all the copies of the work published with the authority of the author or other copyright proprietor bear the symbol © accompanied by the name of the copyright proprietor and the year of first publication placed in such manner and location as to give reasonable notice of claim of copyright.

The provisions of paragraph 1 of this article shall not preclude any Contracting State from requiring formalities or other conditions for the acquisition and enjoyment of copyright in respect of works first published in its territory or works of its nationals wherever published.

The provisions of paragraph 1 of this article shall not preclude any Contracting State from providing that a person seeking judicial relief must, in bringing the action, comply with procedural requirements, such as that the complainant must appear through domestic counsel or that the complainant must deposit with the court or an administrative office, or both, a copy of the work involved in the litigation; provided that failure to comply with such requirements shall not affect the validity of the copyright, nor shall any such requirement be imposed upon a national of another Contracting State if such requirement is not imposed on nationals of the State in which protection is claimed.

In each Contracting State there shall be legal means of protecting without formalities the unpublished works of nationals of other Contracting States.

If a Contracting State grants protection for more than one term of copyright and the first term is for a period longer than one of the minimum periods prescribed in article IV, such State shall not be required to comply with the provisions of paragraph 1 of this article III in respect of the second or any subsequent term of copyright.
