If it is a generic domain (.com, .net, .org, .info, .biz), or a .cat, .eu, .be, .mobi, .name, .tv, .cc or .ws domain, you can request the transfer. This is because these domains require the express authorisation from the domain owner, either by email or in writing and the confirmation email sent to the administrative contact in the case of generic, .cat, .mobi and .name domains does not require express authorisation. If it is a .es, .com.es, .nom.es or .org.es domain, you cannot request a transfer because express authorisation is required from the administrative contact's email for the transfer process to be successfully completed.
