A Temporary Certificate of Entitlement (TCOE) cannot be cancelled. The TCOE is the result of a successful bid which not only contributes to the setting of the COE Quota Premium but also deprives another person from obtaining a COE at the same exercise. Hence, prospective vehicle owner must be prepared to utilise the TCOE that is successfully bid under his/her name to register the vehicle before the TCOE expiry date. If the owner chooses not to utilise the TCOE for whatever reason, the bid deposit would be forfeited.
