Yup Translation is very hard, you need someone who is not only fluent in both languages but quite often also very familiar with the subject being translated. I've seen professional translators who've been replying to "you got that wrong, I prefer X translation" go into quite deep detail about exactly how and why they made the choice they did and point out both might have been correct for general use but they chose their version because of something like "it was more accurate for the context and time period" or "It was the better choice for the character.
in my youth I spent far too much time laughing at some of the anime fandom who were convinced fansubs done by people who often had very little experience of the language were always better than the "official" translations*.
For legal stuff every single word and bit of punctuation can be vital, as any ambiguity can change the meaning of the contract or provide an unintended way out of it (or worse for the company, bind them to something expensive they didn't intend to do).
*Possibly my favourite one was an argument that went on for dozens of comments over the bra sizing of a character of all things, where it was claimed the official translation was censoring or something because it gave a different size to what was "clearly said" in Japanese, It turns out the Translator knew something the "better fan translators" didn't, Japan used a slightly different size chart, so for the translation they'd actually converted it to the US size as leaving it at the "clearly spoken" Japanese size would have been wrong in American.
