The key is to recognize that this can happen to any of us and a plan should be in place.  Each businesses’ plan can be unique to the business and personality(s) of the owner(s).  

One could writers / probably has writen a book on this.  I am sure you can find more than one.  Good financial advisers should be able to help you thorough the development of a plan; which can be less complicated than you may think ... though may take quite some time to develop as it will become part of your core business functionality  

Sorry I don’t have time to write the book
