If someone has died at home, then you will need to contact the family doctor and the Funeral Director.
In normal circumstances, the family doctor will issue a Medical Certificate of Death, which you will need to take to the Registrar.
If the cause of death is uncertain or the death was sudden, then the Doctor will probably report the death to the Coroner. See our guide to Coroners investigations.
If someone has died in a hospital or a residential home, those in charge will contact a doctor and inform you when and from where the Medical Certificate of Cause of Death will be available.
