GuiaTraductorJurado — Spain's sworn translators, indexed by language and province
8,391 MAEC-certified translator-interpreters across 38 languages and 50 provinces, so anyone needing an official translation finds the right professional in minutes.
The starting point
Immigration paperwork, university degree recognition, cross-border contracts — Spanish authorities demand sworn translations for all of them, yet locating a certified professional for the right language pair was needlessly painful. The government's MAEC register exists, but it was never designed for searching. This site restructures it into a browsable product where language, province and document type intersect in a couple of clicks.
The homepage walks visitors through a four-step flow — pick the language, pick the province, compare profiles, request a free quote — and each step maps onto an actual navigation layer of the site rather than marketing fluff.
Feature set
- Free-text search over names, languages and cities, complemented by structured browsing per language and per province.
- Rich profiles showing certified languages, MAEC licence number, phone, town and starred reviews.
- 38 language hubs, from English (5,193 translators) down to Japanese, including Catalan, Galician and Basque.
- Document-type pages — academic degrees, birth and marriage certificates, criminal-record checks, powers of attorney — each with market-rate guidance.
- Featured translators on the homepage with visible ratings and review counts.
- A blog focused on the bureaucratic procedures that trigger the need for certified translation.
Languages and provinces covered
Published totals: 8,391 sworn translators, 38 languages, 50 provinces. Distribution mirrors Spain's actual demand — English 5,193, French 1,969, German 861 — while geographically Madrid leads with 2,226 professionals, ahead of Alicante (945) and Barcelona (751). Any language-province pairing with enough volume gets a landing page of its own, matching how people genuinely search.
The long tail is where the product earns its keep, with counts shown right on the homepage:
- Migration-driven languages: Romanian (109 translators), Arabic (97) and Russian (50).
- Co-official languages: Catalan (109), Galician (13) and Basque (11) — a segment competitors barely serve.
- Scarce pairs such as Chinese (12) or Japanese (6), where ranking first is decisive.

Technical architecture
Underneath sits a Laravel + PHP backend on MySQL tuned for thousands of programmatic pages: translator profiles, language hubs, province hubs and document pages, all with metadata and structured data emitted straight from the data model. The dual taxonomy (language plus territory) is harder to get right than a flat directory, and the internal-linking graph is computed so no profile page ends up orphaned.
Delivery follows my house rules: server-rendered HTML, compiled Tailwind CSS, JavaScript kept to a minimum. No site builders, no generic themes — performance and crawlability come first.
UX calls that pay off
Two product decisions carry most of the weight. First, publishing market-rate guidance per document type: "how much does a sworn translation cost" is the niche's most-asked question, and answering it up front earns both trust and long-tail traffic. Second, stating plainly that sworn translations are valid nationwide — removing an imagined geographic restriction instantly widens the user's options and increases contact conversions.
Questions people ask
What does "sworn translator" mean in Spain?
A translator-interpreter certified by Spain's Ministry of Foreign Affairs (MAEC). Their translations carry full legal validity and are required for immigration files, degree recognition, contracts, certificates and court documents.
How much ground does the directory cover?
The homepage lists 8,391 sworn translators working in 38 languages across 50 provinces. English dominates with 5,193 professionals, French follows with 1,969 and German with 861.
Is the register based on an official source?
Yes — the site describes itself as a directory built on the official MAEC list, and each translator profile displays the MAEC licence number alongside certified languages and contact details.
Must the translator live in my province?
No. As the site itself points out, a sworn translation is valid throughout Spain regardless of where it was produced; the province filter is a convenience, not a legal constraint.
