Get the medical certificate of the cause of death
Before a death can be registered, a doctor confirms the cause of death. In England and Wales every death is now reviewed by a medical examiner — an independent senior doctor — and the certificate is usually sent electronically straight to the register office. The medical examiner's office will call you to explain the cause of death and tell you when the certificate has gone across.
If the death was unexpected, or the cause isn't clear, it may be referred to a coroner (procurator fiscal in Scotland). That can add days or weeks, and it pauses the registration deadline — you haven't missed anything and you don't need to chase.
