You are a developer or a creative and have never had a dispute with one of your customers? Congratulations, you belong to the lucky few. But even then it’s better to prevent than to cure. Problems regularly arise around questions such as ‘to whom does intellectual property belong now?’, ‘what should I see as additional work and can I be invoiced for it?’, ‘what should I regard as a finished work?’ and so on. If there are no clear contractual stipulations about this, you end up in a discussion that often only comes to an end when it is too late for both parties.
