I have planed to change the ownership of the domain name but I don't how it is possible? Can anyone suggest me How do I change the ownership of my domain name?
Have you tried to contact your Domain Registrar support? I believe that customers' safety should be the main goal for them, so I suppose it can be a good solution for you.
Depending on the registrar you will need to Push the domain into the recipient's account. Select the domain within your account and the option should become clear, else look in their help pages.
Every registrar gives you facility to change whois details your self, so you can just log into the panel they provide and change in the fields accordingly.
