The documents required will differ depending on whether the visitor is other than a legal guardian or an adult guardian.

Please see below for the documents required for the procedure.

Documents required for cancellation

  • If the contract holder is a minor and the representative is a facility-related person, a certificate verifying that the agent is a facility staff member is also required.
  • If the contract holder is missing, a certificate confirming the missing status is also required.
