Recently a friend of mine(lets say Mathew) planned to start a website. Since he has a big Facebook page. So he contacted his friend(lets say John) who has a hosting and domain registering company. And then John registered the domain name of Mathew's need in his company in Mathew's email id. Then both of them fight over something( don't want to go into details of their fight) and now Mathew fears that John will do something and he will loose the domain. Need help. can John do anything that will make the domain lose to Mathew? ANd if he can what is the solution? can he change the domain registrar?
