Apostille is the only Thai-side step
Spain has been party to the Hague Apostille Convention since 25 September 1978. After Thailand's accession on 28 February 2027, the Spanish Embassy in Bangkok (Calle Lake Ratchada, Sathorn) will cease all Thai-document legalisation. A Thai MFA Apostille — issued by the Department of Consular Affairs, Chaeng Wattana — is the sole and final Thai-side authentication accepted by every Spanish authority: Registro Civil Central, Subdelegación del Gobierno (NIE/TIE), Ministerio de Universidades (Homologación), Notarios, and Audiencia Nacional.
Reverse direction: Spanish public documents destined for Thai use carry an Apostille from the Ministerio de Justicia (for judicial documents) or the Colegio Notarial (for notarised documents). The Royal Thai Embassy in Madrid no longer attests Spanish documents either.
Traductor-Intérprete Jurado del MAEC — non-negotiable
Every Thai document used in Spain must be translated by a Traductor-Intérprete Jurado appointed by the Ministerio de Asuntos Exteriores, Unión Europea y Cooperación (MAEC). The translator's number appears on the MAEC public roster (Oficina de Interpretación de Lenguas). The sworn translation carries the translator's stamp, signature, and a Certificación stating the translation is faithful — required to be on consecutive pages with the source copy bound in.
Translations produced in Thailand — even MFA-stamped — are not accepted by Registro Civil, notarios, or Subdelegaciones. NYC partners with 6 Traductores Jurados (THA→ESP) in Madrid, Barcelona, and Valencia. Standard turnaround 3–5 business days at €55–85 per page. Combined Bangkok-side Apostille + Madrid-side jurada pack: THB 1,500 MFA + €350–500 jurada per civil bundle.
NIE / TIE and the Subdelegación filing
A Thai national obtains the Número de Identidad de Extranjero (NIE) by filing form EX-15 at a Spanish consulate abroad or at the Oficina de Extranjería of the relevant Subdelegación del Gobierno once in Spain. Supporting documents: Apostilled passport copy + Apostilled criminal record + sworn Spanish translation of the criminal record + Modelo 790 código 012 tasa (€9.84) + justification of cause (work contract, study admission, family reunification).
After arrival, the TIE (Tarjeta de Identidad de Extranjero) is issued at the Oficina de Extranjería upon biometric capture, valid for the duration of the residence permit. NYC's NIE/TIE package: document audit + Apostille + jurada + Modelo 790 + appointment booking via the cita previa portal. Standard turnaround 10–15 business days for the Thai-side workflow.
Registro Civil Central transcription and Homologación
Thai marriages, births, and deaths involving a Spanish citizen transcribe at the Registro Civil Central, Calle Montera 18, Madrid (or by a competent Consulado for non-Spanish-resident citizens). Documents required: Apostilled Thai certificate + sworn Spanish translation + Apostilled birth certificate of the Spanish party + DNI + libro de familia request. Transcription time 3–9 months depending on Madrid backlog.
Academic Homologación for regulated professions (medicine, nursing, architecture, engineering, law) is filed with the Ministerio de Universidades. Required: Apostilled diploma + Apostilled transcript + sworn Spanish translation + plan de estudios + CV. Equivalencia is the parallel procedure for non-regulated degrees and is faster (6–9 months) than Homologación (12–24 months).
