There are, in Mexico, two certifications for sworn translators: the local certification granted by the Superior Court of Justice corresponding to each of the 32 states and the one of the Superior Court of Justice corresponding to the federation. Both institutions establish that a written and oral examination shall be passed for a translator to be recognized as an expert or "sworn" (certified) translator (perito traductor); this type of translator does not swear before the court to be authorized. Although the local certification is officially valid for only one of the 32 states, a translator from any of the states may work for a client from any of the states, provided that the client accepts the translator.[10]
