I have read this quote in http://www.businessinsider.com/guardtime-estonian-health-records-industrial-blockchain-bitcoin-2016-3:
Mike Gault, co-founder and CEO of Guardtime, told Business Insider: "The only thing that you can’t do online in Estonia is get married or get divorced. Otherwise you don’t need to go to a government office."
Can all administrative procedures except getting married or getting divorced be done online in Estonia?
