1. Give each document a clear job
Start with four questions: What work was promised? Who owns the image rights? What may the client do with the images? What use of an identifiable person has been authorized? A signed invoice may prove a payment obligation without answering all four. Paying for a portrait does not by itself settle the scope of the client’s usage rights, and owning copyright does not remove a subject’s privacy or publicity interests.
Before a shoot, create an assignment folder with the current service agreement, approved scope, payment schedule, applicable license, and any relevant releases. Identify who needs to sign and in what capacity. A corporate contact purchasing headshots may have authority to order the service without having authority to grant every employee’s likeness permissions.
