A joint and several administrator is responsible for managing and representing the company, along with other joint and several administrators, who can act each interchangeably on their own, without the needing to meet to make decisions about the company. There always has to be more than one joint and several administrator. If the joint and several administrator has a paid position, or if they have more than a quarter of shares of the company, they must pay Social Security taxes. In Spain, joint and several administrators are governed by the Companies Act, Capital Law of 2010 (Royal Law 1/2010 of 2 July)
