Usually, it is enough to send me a complete copy of the document as a photo or scan by email and to then present the competent authority with the original document together with the translation. I attach the copy of the source text to the translation, so that the original and copy can be compared with each other.
In rare cases, the competent authority insists on a translation based on the original. If you show me the original document, I would be happy to note in the Translator’s Declaration that I was presented with the original.
