Almost every request that reaches us for Breton is, on inspection, a French job with a Breton name inside it. Brittany is part of France and registers births, marriages and deaths in French at the mairie of the commune, so the certified translation is French. Genuine Breton work exists and it is personal: letters, parish material, an inscription, a recorded interview for family history. Prism Language Solutions handles both and tells you which you have before quoting.

Demand for this language in the United States is minimal and we would rather write that down than pretend otherwise. A survey by the TMO institute for the Region of Brittany, published in January 2024, counted about 107,000 Breton speakers, down from 214,000 six years earlier, and almost all of them are also French speakers. There is no US community of Breton monolinguals to serve.
What there is: genealogists, probate attorneys and a few academic clients, plus the occasional elderly visitor in a hospital. That is the honest shape of the work.

Breton Family Papers and the French Records Behind Them
The document that carries legal weight is the French one. An acte de naissance is issued by the mairie of the commune of birth, and the version a US filing usually needs is the copie intégrale, which names both parents and reproduces the marginal entries recording later marriages, divorces and death. Those margins are frequently the point, and a translation that renders only the central entry looks complete while omitting the facts.
So we quote French rates for French pages and say why. If your bundle is entirely certificates, you do not need a Breton linguist at all: see French translation and certified translation. France issues apostilles, so where a receiving body wants one, get it attached before the document comes to us.
Fañch and the Tilde: Breton Names on a French Certificate
There is one distinctly Breton problem on an otherwise French certificate, and it concerns names. In 2017 the registry at Quimper refused to record the given name Fañch because the tilde was not among the characters a 2014 circular permitted. The Rennes court of appeal allowed it in November 2018, and the prosecutor’s further appeal failed the following year.
The practical result is inconsistency across a single family’s papers. A Breton given name may appear with its diacritic on one document, without it on another, and in a French-equivalent form on a third, while a US passport or green card carries only what the American system could accept. Spelling follows the travel document, the source form is printed exactly as written, and a translator’s note explains the relationship so an officer comparing two records is not left guessing.Breton Letters, Parish Records and Three Spelling Systems
Where genuine Breton text turns up, it is usually old, handwritten and personal: letters home, a parish register, a devotional book, a gravestone, sometimes a cassette recorded by a grandmother. This is the work we actually do in the language, and most of it is commissioned for probate or family history rather than for an agency.
Written Breton has no single tradition to fall back on. The unified peurunvan orthography was agreed in 1941, a rival university system, skolveurieg, followed in 1955, and an interdialectal system appeared in the 1970s; older material predates all three and spells by ear. On top of that sit the dialects, with Vannetais in the south-east standing well apart from the Kerne, Leon and Treger varieties. We ask which part of Brittany the family came from, assign accordingly, and mark anything we cannot read rather than producing a confident guess.
When a Breton Interpreter Is Worth Booking
Rarely, and we will usually talk you out of it. A French interpreter serves for almost every appointment involving someone from Brittany, is far easier to arrange and, in a courtroom, is available with state certification. The exceptions are narrow: a very old speaker whose French has receded, a witness recalling a childhood lived in Breton, a recorded family-history interview where the language itself is the material.
When Breton is the right call, the work runs by video. There are not enough speakers under sixty in Brittany itself to support a US roster, and we will not invent one; if an interpreter is genuinely within reach of your appointment we will say so, and if not we will say that too. No state examines court interpreters in Breton, so a judge decides what qualifications satisfy the court. Guide prices sit on the pricing page.
