You have to renew your license or it will lapse, even if:

a) You are awaiting a reply to an application for a transfer. The notice will be sent to the previous owner. Follow up with him/her.
b) The original owner has passed away and you are awaiting finalisation of the estate.
c) You intend to sell your premises and license, and the transaction has not been finalised. You, the license owner, have to renew it to keep it valid.
