To become a baronet, you almost always have to inherit the title. A baronetcy is a hereditary British honor that passes automatically on the death of the current holder, under the succession terms set out in the original Crown grant, so the practical question of how to become a baronet is really a question of proving you are the next qualified heir and getting your name onto the Official Roll of the Baronetage. New baronetcies can in theory still be created by the Crown, but the last one outside the royal family went to Denis Thatcher in 1990, and no one can apply for, lobby for, or buy one.
Inheritance Is the Only Real Route
A baronetcy is a hereditary honor granted by the British Crown, but it is not a peerage. Baronets are legally commoners and have no seat in the House of Lords, though the title outranks most of the knightage. What the title does have is a bloodline attached to it. When the current baronet dies, the title passes to the next qualified heir without any further act by the Crown. There is no application process for the honor itself. Either you fall within the succession set out in the founding document, or you do not.
That founding document is called the Letters Patent, and it contains a “remainder” clause specifying which descendants can inherit. Everything about who becomes the next baronet turns on the exact wording of that clause.
Who Qualifies as Heir
The most common remainder limits succession to “heirs male of the body lawfully begotten.” In plain terms, that means legitimate sons and their male-line descendants only. The title goes to the eldest son of the deceased baronet; if he predeceased his father, it goes to his eldest son, and so on. A majority of baronetcies follow this male primogeniture pattern.
A minority of grants use different language. Some allow descent through “heirs of the body” without specifying male, which can permit daughters to inherit. Certain Scottish baronetcies also allow female-line descent. If you are trying to work out whether you have a claim, the first document to find is the original Letters Patent for that specific baronetcy.
Two terms come up often in succession questions. An heir apparent is someone whose right to succeed is locked in provided they outlive the current baronet, typically the eldest son. An heir presumptive has a claim that could still be displaced, most commonly a younger brother whose position vanishes if the baronet later has a son. If male-line descendants are believed to exist but none has proved a claim, the baronetcy becomes dormant. If it becomes clear that no legitimate male-line descendants survive at all, it is declared extinct and reverts to the Crown.
Proving Your Claim and Getting on the Official Roll
The title passes the instant the previous baronet dies, but you cannot use it in any official context until your name is on the Official Roll of the Baronetage. That register was established by a Royal Warrant of King Edward VII in 1910. The warrant states that no person whose name is absent from the Roll “shall be received as a Baronet” or addressed as such in any commission, Letters Patent, or official document. Getting registered is the practical part of becoming a baronet.
Where the Claim Goes
Claims are submitted to the Crown Office, which sits within the Ministry of Justice. The evidence is then reviewed by the College of Arms for most baronetcies, or by the Lord Lyon King of Arms if the baronetcy is Scottish with a territorial designation. Whichever authority reviews the case sends a report to the Registrar of the Baronetage, who decides whether to add your name to the Roll.
What You’ll Need to Submit
For a straightforward father-to-son succession, the minimum is usually the birth certificate of the claimant, the marriage certificate of the claimant’s parents, the death certificate of the previous baronet, and a Statutory Declaration.
Collateral successions are harder. If you are claiming through a more distant line, say as a cousin or a descendant of a younger son several generations back, you have to prove your descent from the second baronet and demonstrate that every male line senior to yours has gone extinct. That can mean assembling birth, marriage, and death certificates stretching back generations, sometimes across multiple countries.
When DNA Can Change the Answer
Paper genealogy is no longer the only evidence that counts. In 2016, the Judicial Committee of the Privy Council decided the disputed succession to the Baronetcy of Pringle of Stichill. Two men claimed the title. Y-chromosome testing gathered as part of a surname genetics project indicated that the tenth baronet’s lineage diverged from what family records suggested, meaning the ninth baronet was not the biological son of the eighth. The Privy Council held that the DNA evidence was admissible, saying there was “no legal ground for excluding” it, and confirmed Murray Pringle as the rightful heir over the grandson of the tenth baronet.
The justices observed that DNA evidence could “reopen a family succession many generations into the past.” For anyone pursuing a claim, or defending one, that precedent matters. The paper trail and the biological trail do not always agree, and either side of a contested succession can now put the question to a test.
You Cannot Buy a Baronetcy
Baronetcies cannot legally be bought or sold. They are Crown honors attached to a bloodline, not property that transfers by contract. Websites advertising “British titles” for sale are almost never offering genuine baronetcies, and the offerings usually fall into one of two categories that are not baronetcies at all.
A Scottish feudal barony is a landed dignity that can be bought, sold, and bequeathed as a form of incorporeal property. The purchaser can style themselves “Baron of [place name],” but this is a feudal dignity rather than a title of nobility or a Crown honor, and it carries no precedence in the British order of rank. A Lordship of the Manor is an English historical designation tied to a parcel of land; buying one lets you append “Lord of the Manor of [place]” after your name and nothing more. Neither is a baronetcy, and anyone offering to sell you one is either confused or dishonest.
New Creations by the Crown
The sovereign can create new baronetcies on the advice of the Prime Minister, with nominations passing through subject-specialist committees and the Main Honours Committee in the Cabinet Office before a recommendation goes to the King. In practice this has effectively stopped. The last hereditary baronetcy outside the royal family went to Denis Thatcher in 1990, one of only a handful of hereditary titles given to non-royals since the mid-1960s. There is no route by which an individual can apply for or request the honor. Any future creation for a commoner would arrive as an unsolicited decision by the Crown on ministerial advice.
The Push To Let Women Inherit
The male-only rule is under pressure. Several private members’ bills have been introduced in Parliament seeking to allow women to inherit hereditary titles, including baronetcies. The Succession to Peerages and Baronetcies Bill, introduced in the House of Lords during the 2023–24 session, proposed allowing female heirs to succeed while keeping male-preference primogeniture, so sons would still inherit before daughters but daughters would no longer be skipped entirely. None of these bills has become law.
The legal argument is sharpening in parallel. During parliamentary debate in February 2024, members noted that Section 14 of the Human Rights Act 1998 makes sex-based discrimination illegal where both sexes can perform the function required, and suggested that a woman denied a title by the male-only rule could well succeed if she took her case to the European Court of Human Rights. No test case has yet reached that stage. If you are a daughter whose claim is currently barred by the wording of the original Letters Patent, this is the area of law to watch.
