Sworn translations of documents needed to register imported vehicles in a short amount of time If documents for vehicles imported from abroad are not in the Slovak or Czech language, you’ll need to submit them to the authorities with a sworn translation in the Slovak language. What documents do the authorities usually require? In order to register an imported vehicle from abroad, the competent authorities almost always require a sworn translation of the following documents: Vehicle registration Confirmation of vehicle deregistration Invoice or purchase agreement Vehicle safety/roadworthiness test (MOT) and exhaust emissions inspection (EC) — known locally as an STK and EK respectively COC (Certificate of conformity – proof of vehicle originality) However, we recommend checking with the office you plan on submitting your documents to in advance whether a sworn translation will be required. Depending on the country, you may not need to submit translations of all five documents. Most offices require a translation of your vehicle registration and invoice.
