What do the shareholders of a corporation need to do to legally practice in a Professional Corporation?

To legally practice in a Professional Corporation, shareholders need to be licensed professionals in the designated profession. This requirement ensures that the individuals who are managing and operating the corporation possess the necessary qualifications and expertise related to their field. For example, in a Professional Corporation established for lawyers, all shareholders must be licensed attorneys. This regulation is essential because it upholds the standards of the profession and ensures that the services rendered by the corporation are compliant with industry regulations and ethical guidelines.

The other options, while they may pertain to business operation in a general sense, do not directly address the requirement specific to Professional Corporations where professional licensure is a fundamental prerequisite for shareholders to ensure the quality and legality of the services provided. Therefore, being licensed professionals is the critical factor that distinguishes a Professional Corporation from other types of business entities.
