A register office cannot issue paperwork to allow a body to go outside England or Wales. If a person died in Haringey (not in a hospital, as there are no hospitals in Haringey), the death will be registered by Haringey but paperwork for the body to leave England will be issued by the Coroner directly to the funeral director. Please speak to your funeral director or the Coroner covering Haringey for further advice:
Advising other agencies about a death: Tell Us Once
A service called Tell Us Once allows government and local government departments to be made aware that a person has died by making a single online report or phone call. An access code for using Tell Us Once will be given to you at your death registration appointment. You then have four weeks to inform Tell Us Once that the person has died. You can find more information on GOV.UK (external link).
