1) How many people died intestate last year in the UK

2) How much revenue the government got from those intestate deaths.

3) How is this money spent and on whom.

We said

Thank you for your enquiry.

Unfortunately we only hold information recorded in connection with registering the death, which does not include any information relating to the administration of their estate. You may be able to obtain some information from Her Majesty's Revenue and Customs.
