whts the procedure and wht r my chances? where do i go for this? shud i approach a lawyer?
Unless you can somehow prove trademark rights, then you've no chance of legally grabbing the name you want from someone else.
Everybody wants something. You either pay up or move on elsewhere.
Think of it this way: if you have a domain name you're not currently using and someone else wants it, would you appreciate that person using legal means to grab it from you?
