18 Intellectual Property Act, No. 36 of 2003 (2) In respect of a work of joint authorship, the coauthors shall be the original owners of the economic rights. If, however, a work of joint authorship consists of parts that can be used separately and the author of each part can be identified, the author of each part shall be the original owner of the economic rights in respect of the part that he has created. (3) In respect of a collective work, the physical person or legal entity at the initiative, and under the direction, of whom or which the work has been created shall be the original owner of the economic rights. (4) In respect of a work created by an author employed by a physical person or legal entity in the course of his employment, the original owner of the economic rights shall, unless provided otherwise by way of a contract, be the employer. If the work is created pursuant to a commission, the original owner of economic rights shall be, unless otherwise provided in a contract, the person who commissioned the work. (5) In respect of an audiovisual work, the original owner of the economic rights shall be the producer, unless otherwise provided in a contract. The co-authors of the audiovisual work and the authors of the pre-existing works, included in, or adapted for, the making of the audiovisual work shall, however, maintain their economic rights in their contributions or pre-existing works, respectively, to the extent that those contributions or pre existing works can be the subject of acts covered by their economic rights separately from the audiovisual work. Presumption of authorship and of representation of the author. 15. (1) The physical person whose name is indicated as the author on a work in the usual manner shall, in the absence of proof to the contrary, be presumed to be the author of the work. The provisions of this section shall be applicable even if the name is a pseudonym, where the pseudonym leaves no doubt as to the identity of the author. (2) The physical person or legal entity whose name appears on an audio-visual work shall, in the absence of proof to the contrary, be presumed to be the producer of the said work.
