A death can be registered in the office of any Registrar of Births, Marriages and Death, irrespective of where the death occurs. The staff of the hospital (if the death occurred in a hospital) or of your local health centre, will be able to tell you where you can register the death.
Deaths must be registered as soon as possible after the death and no later than 3 months. It is usually registered by the next of kin. Alternatively, it may be registered by a person who was present during the death or final illness of the deceased, or has knowledge of the required particulars. Further information on who can register the death is available on the General Register Office website.
