The use of the title ofPrincess of the United Kingdom of Great Britain and Northern Ireland is entirely at the will of thesovereign, and is now expressed inletters patent. Individuals holding the title of princess will usually also be granted the style ofHer Royal Highness (HRH). The current letters patent were issued in 1917 duringWorld War I, with one extension in 2012.

Between 1714 and 1917, pursuant to the then custom, daughters of the monarch and daughters of male-line descendants of a monarch were accorded the rank of a British princess. KingGeorge V issued letters patent on 30 November 1917 (issue 30428, Dec. 14, 1917, p. 2.), predefining who held the title, style and rank of a British Princess^[1] to restrict the automatic assignment of the title "princess" and the use of the style "Royal Highness" to the following persons:

• the legitimate daughters of a British Sovereign
• the legitimate male line granddaughters of a British sovereign.

On 31 December 2012, QueenElizabeth II issued letters patent enabling all children of theeldest son of thePrince of Wales to hold the titleprince orprincess and styleRoyal Highness, as opposed to only the eldest son (the 1917 patent having extended "prince" to his eldest living son).

The wife of aBritish prince whose marriage has been approved by the British Sovereign is automatically accorded the status of the prince (princess) and the feminine form of her husband's titles.

Under the current practice, princesses of the blood royal are the legitimate daughters and the legitimate male line granddaughters of aBritish sovereign. They aredynasts, that is potential successors to the throne. For these individuals, the title "Princess of the United Kingdom of Great Britain and Northern Ireland" and the style "Her Royal Highness" is an entitlement for life. The title Princess and the styleRoyal Highness is prefixed to the Christian name, before another title of honour. From 1714 until 1917, the male-line great-granddaughters of the Sovereign were titled "Princess of Great Britain and Ireland" with the style "Highness". Since 1917,^{[citation needed]} the male-line great-granddaughters of the Sovereign have held "the style and title enjoyed by the children of dukes". For example, the daughters ofPrince Richard, Duke of Gloucester, a male line grandson of George V, are styledLady Davina Windsor andLady Rose Gilman.

The legal wife of aBritish prince is also entitled to the status and rank of a British princess. If their husband is not the holder of his own substantive title, then the wife of a British prince has the right to be styled as Princess followed by their husband's first given name.^[2] However, if their husband is the holder of either a Dukedom or an Earldom then this takes precedence.^[2] For example, upon her marriage toPrince Michael of Kent in 1978,Baroness Marie-Christine von Reibnitz assumed the title and style of "Her Royal Highness Princess Michael of Kent". Similarly, upon her marriage to thenPrince Richard of Gloucester, the formerBirgitte van Deurs assumed the title and style of "Her Royal Highness Princess Richard of Gloucester". Upon marriage, the wife of the prince of Wales becomes "Her Royal Highness The Princess of Wales". Upon marriage, the wife of a royal duke (or earl) becomes "Her Royal Highness The Duchess (or Countess) of X". When Prince Richard of Gloucester succeeded to his father's dukedom in 1974, his wife became "Her Royal Highness The Duchess of Gloucester". Since 1714, only four princesses were at marriage known in their title by their husband's name, since all the others took the duchess form of theroyal duke's title. The four arePrincess George of Cumberland,Princess Arthur of Connaught,Princess Richard of Gloucester andPrincess Michael of Kent.

Princesses by marriage are entitled to the style "Royal Highness" by virtue of marriage, and retain the style if widowed. However, Elizabeth II issued letters patent dated 21 August 1996 stating that any woman divorced from a prince of the United Kingdom would no longer be entitled to the style "Royal Highness". This has so far applied toDiana, Princess of Wales, andSarah, Duchess of York. The title of HRH is not intrinsically linked to the title of Princess. Diana was restyled as "Diana, Princess of Wales" following her divorce as a courtesy of the late Queen Elizabeth II having been officially styled as The Princess of Wales during marriage. If Diana had ever remarried then she would have lost the right to the style and title completely.

Since the passage of theRoyal Marriages Act 1772, there were a few instances in the reign of King George III in which princes of the blood contracted marriages without consent of the king. This meant they were not legally married, denying the woman the lawful style "Her Royal Highness", as well as any title in the peerage. For example,Prince George, Duke of Cambridge, a male-line grandson of KingGeorge III, 'married'Sarah Louisa Fairbrother: the marriage was in contravention of theRoyal Marriages Act, and therefore legally invalid. Accordingly, the duke's wife was never titled the Duchess of Cambridge or accorded the style "Her Royal Highness". Instead, she was known as "Mrs FitzGeorge". An exception to the rule was created for KingEdward VIII following his 1936 abdication. KingGeorge VI issued letters patent dated 27 May 1937 that entitled The Duke of Windsor, as Edward was now entitled, "to hold and enjoy for himself only the title, style or attribute of Royal Highness so however that his wife and descendants if any shall not hold the said title, style or attribute".

There is also the case when a princess of the blood royal marries a British prince. She also becomes a princess by marriage and will be addressed in the same way. An example of this situation was the latePrincess Alexandra, Duchess of Fife, when she married her cousinPrince Arthur of Connaught and became "Princess Arthur of Connaught, Duchess of Fife".

Typically a princess by marriage should not be called princess followed by her first name. Diana, Princess of Wales, was consistently referred to as "Princess Diana" by fans and the media, but this usage of the title is technically erroneous, as she was not the child of a monarch nor the child of a son of a monarch.^[3] However, this tradition was broken once in the past century with Elizabeth II's aunt,Princess Alice, Duchess of Gloucester, being referred to—with permission from the sovereign—in official sources as such following the death of her husband.^[4]

The use of the titles prince and princess and the styles of Highness and Royal Highness for members of the Royal Family is of fairly recent usage in the British Isles. Before 1714, there was no settled practice regarding the use of the titles prince and princess other than theheir apparent and his wife.^[5] Since 1301, the eldest sons of theKings of England (and later Great Britain and the United Kingdom) have generally been createdPrince of Wales and Earl of Chester (though Edward II's eldest son Edward III, was not given the title).^[6] Their wives were titledPrincess of Wales.

The titlePrincess Royal came into being in 1642^[7] when QueenHenrietta Maria, the French-born wife of KingCharles I, wished to imitate the way the eldest daughter of the French King was styledMadame Royale. However, there was no settled practice on the use of the title princess for the Sovereign's younger daughters or male-line granddaughters. For example, as late as the time of KingCharles II, the daughters of his brotherJames, Duke of York, both of whom became Queens regnant, were called simply "The Lady Mary" and "The Lady Anne". The future QueenAnne was styled princess in her marriage treaty toPrince George of Denmark and then styled "Princess Anne of Denmark" once married. However, in exile atSaint-Germain-en-Laye, the deposed James II & VII gave the title of Princess Royal to his last daughter,Louisa Maria (1692–1712).

After the accession ofGeorge Louis of Hanover as King George I, the children, grandchildren, and male line great-grandchildren of the British Sovereign were automatically titled "Prince or Princess of Great Britain and Ireland" and styled "Royal Highness" (in the case of children and grandchildren) or "Highness" (in the case of male line great-grandchildren). QueenVictoria confirmed this practice in letters patent dated 30 January 1864 (the first Act of the Prerogative dealing with the princely title in general terms).^[8]

On 31 December 2012, Elizabeth II issued letters patent enabling all children of the eldest son of thePrince of Wales to enjoy the princely title and style ofRoyal Highness, as opposed to only the eldest son.^[9][10]

• Daughter of a Sovereign:HRH The Princess N (e.g.HRHThe Princess Margaret).
  • The styleHRH ThePrincess Royal is customarily (but not automatically) granted by the Sovereign, when vacant, to the Sovereign's eldest daughter.^[11]
• Daughter of a son of a Sovereign:HRH Princess N of X, whereX is the territorial designation of their father's senior peerage; e.g.HRHPrincess Alexandra of Kent,HRHPrincess Charlotte of Wales,HRHPrincess Lilibet of Sussex.
  • Prior toPrincess Charlotte, a daughter of the Prince of Wales:HRH Princess N
  • Prior to 1917,^{[citation needed]} a daughter of a son of a son of a Sovereign:HH Princess N of X
• From 31 December 2012, daughter of the eldest son of the Prince of Wales:HRH Princess N of X (e.g.HRHPrincess Charlotte of Cambridge, until 2022).

When a princess marries, she still takes on her husband's title. If the title is higher than (or equal to) the one she possesses, she will normally be styled using the female equivalent.^[12] If her husband has a lower title or style, her style as a princess remains in use, although it may then be combined with her style by marriage, e.g.HRH ThePrincess Louise, Duchess of Argyll orHRHPrincess Alice, Countess of Athlone – if that princess had a territorial designation, she may cease its use. It has become customary, however, for a princess who has been granted the title ofHRH The Princess Royal to not combine it with her style by marriage: Princess Anne remainsHRH The Princess Royal rather thanHRH The Princess Royal, Lady Laurence.^[13][14]

A princess by marriage is addressed as "Princess Husband's name"; this is akin to a woman being referred to as "Mrs. John Smith".^{[citation needed]} The only recent time this has broken tradition is with the sovereign's express consent. Namely, with Queen Elizabeth II's auntsPrincess Alice, Duchess of Gloucester, andPrincess Marina, Duchess of Kent. The former was not a princess by birth, while the latter was born a princess of Greece and Denmark. Both women asked the Queen to use their given names after their husbands' deaths.^[4]

• Wife of a prince who has a peerage:HRH The Duchess/Countess of X, or, prior to 1917, possiblyHH (e.g.HRHThe Duchess of Edinburgh andHRHThe Duchess of Sussex)
  • Since 1996, divorced wife of a prince who held a peerage:N, Duchess/Countess of X. (e.g.Diana, Princess of Wales, andSarah, Duchess of York)
• Wife of a son of a Sovereign, who has no peerage:HRH The Princess Husband.
• Wife of another prince who has no peerage:HRH Princess Husband of X. (X usually taken from father's Dukedom; e.g.HRHPrincess Michael of Kent)
• Prior to 1917, the wife of a prince in the third generation, who has no peerage:HH Princess Husband of X.

• There were only two historical princesses who would have been exceptions to the 1917 rule, but they died long before that. The sistersSophia Matilda andCaroline Augusta Maria born in 1773 and 1774 were male line great-granddaughters of George II. All of the other exceptions were still alive in 1917 and were no longer permitted to use the style of HRH and Princess.

There have been several exceptions in recent history to these rules, but all have come by order of the Sovereign, mostly throughletters patent.

• In November 1905, KingEdward VII allowed the two daughters ofLouise, Princess Royal to use a princely title and the style ofHighness.^[15] They were not entitled to the style ofRoyal Highness. The 1917 letters patent which stripped great-grandchildren of a British sovereign of the style ofHighness with a princely title was complicated as it did not technically overrule Edward VII's letters patent, as the former practice was mostly an unspoken courtesy as opposed to a written rule. The elder sister,Princess Alexandra, Duchess of Fife, was already married by that time, toPrince Arthur of Connaught: he was a male-line grandson of Victoria, and so entitled to use the style ofRoyal Highness. Alexandra was therefore styledHer Royal Highness Princess Arthur of Connaught, Duchess of Fife from her 1913 marriage for the rest of her life, and the 1917 letters patent did not change this. Her younger sister,Princess Maud, on the other hand, was unmarried in 1917. Until her 1923 marriage, she continued to use the title of "Princess" granted to her in 1905.^[16] Upon her marriage toCharles, Lord Carnegie, however, she chose to be known asLady Maud Carnegie (or, from 1941,The Countess of Southesk), dropping her princely title.
• Charles III had the style and title His Royal Highness Prince Charles of Edinburgh from birth in 1948, even though he was a female-line grandchild of the Sovereign, being born to the future Elizabeth II, then Princess Elizabeth, Duchess of Edinburgh, during the reign of Elizabeth's father, KingGeorge VI, who had no sons. George VI issued letters patent on 22 October 1948, granting the style to Elizabeth's children. Under the same exception,Anne, Princess Royal was styled Her Royal Highness Princess Anne of Edinburgh from her birth in 1950 until her mother's accession in 1952.
• In 1961, when her son married, theDuchess of Kent asked Elizabeth II to extend the use of a princely title to precede her first name, in order to avoid confusion with her daughter-in-law,Katharine Worsley, the new Duchess of Kent. As she was born a princess of Greece and Denmark, this was not incredibly notable, although traditionally she would have been styled asHer Royal Highness The Dowager Duchess of Kent. After this she was styled asHer Royal Highness Princess Marina, Duchess of Kent.
• In 1974, theDuchess of Gloucester asked Elizabeth II for the same title as her sister-in-law, then Princess Marina, Duchess of Kent, with a princely title preceding her first name. Unlike Princess Marina, Alice had never been a princess in her own right, thus this allowance was far more unusual. Instead of being referred to asHer Royal Highness The Dowager Duchess of Gloucester, as is customary, she becameHer Royal Highness Princess Alice, Duchess of Gloucester.
• In 2003, upon the request of Elizabeth II's youngest son,Edward, his children would be styled as the children of an earl, though still retaining their royal titles.^[17] The children would be able to decide if they would want to use the title once they turned eighteen.^[18] As male-line grandchildren of a British monarch,Lady Louise Mountbatten-Windsor and theJames, Earl of Wessex, would traditionally enjoy a princely title and style.
• In December 2012, Elizabeth II issued letters patent that stated that all children born to the eldest child of the Prince of Wales (then her sonCharles), would enjoy a princely title and style, and not just the eldest son. Although in effect since 2012, it was not used in practice until the birth ofPrincess Charlotte in 2015.

Each of the following women married a royal prince but as their marriages were invalid under theRoyal Marriages Act 1772, they did not become princesses:^{[citation needed]}

• Maria Anne Fitzherbert, marriedGeorge, Prince of Wales in 1785
• Lady Augusta Murray, marriedPrince Augustus Frederick, Duke of Sussex in 1793
• Lady Cecilia Buggin, marriedPrince Augustus Frederick, Duke of Sussex. She was later createdDuchess of Inverness.
• Sarah Louisa Fairbrother, marriedPrince George, Duke of Cambridge in 1847

AlthoughWallis Simpson married the Duke of Windsor in 1937, and he was a British prince with the styleHis Royal Highness, having been confirmed as such by letters patent 27 May 1937 from his brother, George VI, Wallis and her descendants from the marriage were expressly denied the style of "Royal Highness" by the same letters patent before she married him.^[34] As a duke's wife, she was always styledHer Grace The Duchess of Windsor. Her husband, theDuke of Windsor, insisted that staff and friends should refer to her as Her Royal Highness.

There have been two instances where a British princess married a British prince:^{[citation needed]} firstThe Princess Mary, daughter of George III, who married her first cousinPrince William Frederick, Duke of Gloucester and Edinburgh; secondlyPrincess Alexandra, Duchess of Fife, granddaughter of Edward VII, who married her first cousin once removedPrince Arthur of Connaught. In the first instance Princess Mary was of higher rank and the Duke of Gloucester and his sister were elevated from the styleHis/Her Highness toHis/Her Royal Highness. In the second instance Princess Alexandra had been granted the styleHer Highness by her grandfather the King; as the wife of a Prince she received the styleHer Royal Highness.

There is also the curious case of Princess Victoria Eugénie of Battenberg, laterQueen Victoria Eugenia of Spain (the daughter ofPrincess Beatrice andPrince Henry of Battenberg). Prior to her marriage toAlfonso XIII of Spain in May 1906, she was styled Her Highness Princess Victoria Eugénie of Battenberg. On 3 April 1906Edward VII, in order to elevate her standing prior to her wedding, raised her status to Royal Highness per royal declaration which read: "Whitehall April 3, 1906. The KING has been graciously pleased to declare and ordain that His Majesty's niece, Her Highness Princess Victoria Eugenie Julia Ena, daughter of Her Royal Highness the Princess Beatrice Mary Victoria Feodore (Princess Henry of Battenberg), shall henceforth be styled and called "Her Royal Highness"; And to command that the said Royal concession and declaration be registered in His Majesty's College of Arms."^[35] Edward VII concurrently issued a Royal Warrant on the elevation which read: "Our Will and Pleasure is and we do hereby declare and ordain that from and after the date of this Warrant our most Dear Niece Princess Victoria Eugénie Julia Ena, only daughter of Our most Dear Sister Beatrice Mary Victoria Feodore (Princess Henry of Battenberg) shall be styled entitled and called "Her Royal Highness" before her name and such Titles and Appellations which to her belong in all Deeds Records Instruments or Documents whatsoever wherein she may at any time hereafter be named or described. And We do hereby authorize and empower Our said most Dear Niece henceforth at all times to assume and use and to be called and named by the Style, Title and Appellation of "Her Royal Highness" accordingly. Given at Our Court of Saint James's, the Third day of April 1906: in the Sixth Year of Our Reign. By His Majesty's Command. M Gladstone"^[36] Whether this made her a British Royal Princess is the subject of debate.

The former Lady Diana Spencer lost the prefix of Her Royal Highness upon her divorce in August 1996, and was restyled as "Diana, Princess of Wales". Buckingham Palace issued a press release on the day the decree absolute of divorce was issued, announcing Diana's change of title, but made it clear that Diana continued to be a member of the British Royal Family. This was confirmed by the deputy coroner of the Queen's Household, Baroness Butler-Sloss, after a pre-hearing on 8 January 2007: "I am satisfied that at her death, Diana, Princess of Wales continued to be a member of the Royal Household."^[37] This appears to have been confirmed in the High Court judicial review matter ofAl Fayed & Ors v Butler-Sloss.^[38] In that case, three High Court judges accepted submissions that the "very name 'Coroner to the Queen's Household' gave the appearance of partiality in the context of inquests into the deaths of two people,one of whom was a member of the Family and the other was not."^[38]
