How are copywrights or royalties handled ?

To establish an exclusivity contract or to transfer a copywright, there needs to be a mention in the legal notices (at the bottom of the quote, but you can also create a separate contract if you like).

The text is strictly interpreted, anything that is not expressly given away can remain in the freelancer's hands.

This is generally brought up at negotiation time with the freelancer.

Copyright transfer

A copyright transfer must imperatively define the field of exploitation by detailing the following points:

The scope : the contract must name the authorized exploitation method(s) (representation if a picture is exposed, reproduction if it is in print).
The destination : the use of the work (e.g. 500 copies of an A3 poster).
The place : details which countries the transfer of copywright will be applicable to.
The duration : you can modulate the duration of the transfer without surpassing the existing duration of rights on the work.

Examples

Example 1: Transfer of the representation and reproduction rights relating to this service for all countries within the exclusive framework of the use and exploitation of the site XXX by the client and this for the duration of the rights' existence.

Example 2: Transfer of the reproduction right of the design on the territory of the European Union within the limit of 100,000 copies or for a period of one year.
