Field-R Law

Field-R Law Offices is a boutique law firm that provides legal expertise in the fields of sports and entertainment law.

We specialize in the areas of contract drafting, negotiation, and consultation regarding copyright, publicity rights, and related intellectual property matters for our entertainment clients in the film, music, broadcasting, publishing, information communications, and digital content industries, and for our clients involved in professional and amateur sports, including baseball, soccer, and martial arts.

The court room is not our main "field" when matters of dispute arise in the business world, we put all our efforts into reaching a speedy settlement outside of the court room. Our expertise includes negotiating the acquisition of rights related to content, handling the legal aspects of business transactions, and acting as an agent when negotiating for athletes. Field-R also assists athletes who negotiate their own contracts with team management by providing advice on the strategic issues involved in the matter. In addition, we provide strategic advice regarding public and media relations including countermeasures for weekly tabloids, crisis management, and international press releases. We also take action through sports mediation and litigation to create laws regarding the portrait rights of athletes and artists in legal areas where there are few precedents or where laws have not been established. Our lawyers have also performed extensive research and given lectures regarding the issue of fair, balanced, and impartial rulings in the field of entertainment and sports law.
