Different states have different rules regarding the validity of non-compete agreements. In California, non-compete agreements are heavily disfavored and will usually only be upheld in a limited number of circumstances. When drafting a non-compete agreement, it is important to keep in mind where the employment will be taking place, so that you can know what types of non-compete agreements are allowable in that location.
Background
California, in general, finds that non-compete agreements after the termination of the employment agreement are not valid and will not be upheld by the courts except in specific circumstances. The California Business and Professions Code Section 16600 states: “Except as provided in this chapter, every contract by which anyone is restrained from engaging in a lawful profession, trade, or business of any kind is to that extent void.” The courts have strictly applied Section 16600 and used this provision to invalidate employment agreements that would have prevented the employee from working for a competitor after the completion of employment.
