The Official Roll of the Baronetage is an official list of baronets kept by the Lord Chancellor; an abridged version is published online by the Standing Council of the Baronetage.
[2] Owing to the requirement to produce legal evidence in support of a claim, if a claim is not pursued immediately on the death of a baronet, it becomes progressively more difficult for each succeeding holder of the title to successfully claim the baronetcy.
According to the Ministry of Justice, it is not necessary to prove succession to a baronetcy in order to use the title.
[3] However, baronets whose names are not on the Official Roll of Baronetage will not: As of January 2020, there are 1,245 baronetcies on the official roll (including about 200 with no incumbent because succession is dormant or unproven); of these 142 are of England, 60 of Ireland, 116 of Scotland, 125 of Great Britain and 802 of the United Kingdom.
[4] The oldest baronetage by date of creation (the Premier Baronet) is Sir Nicholas Bacon, 14th Baronet of Redgrave whose title was created in 1611 in the Baronetage of England.
