Dear Mr Potter,
As per the Will of the late Sirius Black, last male descendent of the Ancient and Most Noble House of Black, all goods and belongings of said House and estate have been transferred into the Potter Vault.
In light of recent events, pertaining to the death of the Dark Lord Voldemort, it has been shown that the line of Potter are the last surviving descendants of the Ancient and Most Noble House of Peverell.
Note that, this only occurred upon the reaching of your majority and that due to recent events you have been uncontactable. However, upon the reaching of your majority, the Ruling of Grimnok was invoked, as set out clearly in the Accords of Merlin. Due to the recent disturbance at the bank, caused by your recent violation of the Vault of the Noble House of Lestrange, we have been unable to provide usual services.
Hence, five days remain until the contents of the Vault of the Ancient and Most Noble House of Peverell reverts to the bank, as set out in the Accords. This is your final notification.
It has also been noted that upon your disappearance you have unlikely been able to receive correspondence, therefore, we would like to remind you that, upon reaching your majority, the Potter Vault has opened to you, as set out in the Will of Mr and Mrs J Potter.
You will be required to present yourself at Gringotts Bank, Diagon Alley to collect your Key.
Upon the event of your death, prior to the collection of your Key, the contents of the Vault will revert to the bank.
Yours sincerely,
Gringotts
