Mexico: Hague Apostille party
Mexico acceded to the 1961 Hague Apostille Convention with effect from 14 August 1995 and Thailand acceded on 30 June 2026 (in force for Thailand 28 February 2027). Thai MFA Apostille is accepted directly by Mexican authorities. The Mexican Embassy in Bangkok (Sathorn) ceased legalisation services in 1995.
Apostille is issued by the Secretaría de Gobernación (SEGOB) for federal documents and by the Secretaría General de Gobierno of each of the 32 states + Ciudad de México for state documents. Every Registro Civil, Notario Público, INM and SAT accepts the Apostille directly.
Most-requested document types

CURP (Clave Única de Registro de Población): national ID issued by Registro Nacional de Población — needs passport + apostilled Birth Certificate + Traducción Pericial.
RFC (Registro Federal de Contribuyentes): tax ID issued by SAT — required to open a bank account or work in Mexico.
Acta de Matrimonio: marriage with a Mexican national at the local Registro Civil — requires apostilled Single Status ≤6 months + Birth Certificate + Constancia de No Impedimento from the Thai Embassy in CDMX.
Cédula Profesional: professional credential recognition (Dirección General de Profesiones, SEP) — requires apostilled Diploma + Transcript + revalidación de estudios.

Mexico-specific pitfalls
1) Traducción Pericial is mandatory under Reglamento del Código Federal de Procedimientos Civiles Art. 271 — translations done in Thailand are not accepted; the apostilled original must be translated in Mexico by a Perito Traductor registered with the TSJ of the destination state.
2) Residente Temporal visas are applied at the Mexican Embassy in Bangkok (Thai Wah Tower II, Sathorn) by online appointment 2–4 weeks ahead — requires apostilled documents + bank statement ≥USD 4,000/month for 12 months or ≥USD 65,000 savings.
3) Acta de Matrimonio: the Registro Civil requires the Constancia de No Impedimento Matrimonial (CNIM) from the Thai Embassy in CDMX under each state's Código Civil — Quintana Roo/Yucatán apply local Maya civil rules differing from other states.
4) Día de Muertos (1–2 Nov) + Semana Santa close INM, SAT and Registro Civil. NYC checks the Mexican calendar before booking.
5) CURP/RFC must match the passport and Acta de Nacimiento — Hispanic naming convention (two surnames) means Thai names must be registered as 'Apellido Paterno' + 'Apellido Materno' as required by Registro Nacional.
