Last year a friend transferred domain to me. Recently he got a message of updating his billing account and I got one on my current godaddy account. However I don't see this domain in my current account.
try the whois database. whois.godaddy.com Is it a GoDaddy domain? Like did he initiate an account change from GoDaddy to GoDaddy or did he transfer to you from a third party like network solutions? Because there is a whole process to finalize the transfer.
