I've recently been trying to purchase a domain that is currently in "suspended" status (still a while to go before drop). The key issue is the original registrant is no longer contactable, and those currently managing the domain can't access the Nominet online service to request registrant transfer (they don't know what email would have been used to register the domain). I need to guide them through this, but it's a new situation for me. What is the best route to take? Do they need to contact Nominet to resolve this?
