Sponsorship agreement plays a very important role in the world of professional sports. Companies are using fame and reputation of the athletes to their advantage, when they use elements of their personality as a mean of increasing the recognition of their brand. With the athletes permission, the company uses them in commercials, they use their name on their companies products and brands. The parties define the details of their arrangement in a sponsorship agreement. Sponsorship agreement is a very specific contract, that has yet to be legally defined. Sponsor (the company) agrees to financially support the athlete, with the purpose of creating positive connection between his brand or a product, and the athlete. The athlete on the other hand, agrees to promote this connection in public. Athlete can also be used as an ambassador of the brand of a specific company, which can be done through endorsement deal. Athletes as influential persons are often subjected to violations of their personality rights. These can be caused by the media, sponsor itself or by others. Violations can result in the form of immaterial or material damage, for which the person is awarded fair compensation.
