Diana's grave is on an island () within the grounds of Althorp Park, the Spencer family home for centuries. The burial party was provided by the 2nd Battalion The Princess of Wales's Royal Regiment, who carried Diana's coffin across to the island and laid her to rest.

After applying personal and inheritance taxes, a net estate of £12.9 million was left to be distributed among the beneficiaries. Her two sons subsequently inherited the majority of her estate.
