Hello, and welcome. I am a licensed attorney and happy to assist.
Sorry to hear of your accident and hope you're doing well. In terms of the translation, you are not required to provide any translation at al unless specified in your actual policy. This would be an unlikely provision, but it would be a good idea to get a copy of your policy and take a look, just in case. Also, since you received confirmation that you do not have to provide translation, you can point that out to your insurance adjuster as showing that is not required of you. Importantly, your insurance company is required by law to timely and fairly evaluate your claim and, if they fail to do so, they can be liable to you for insurance bad faith. If a judge finds bad faith, the insurance company could not only have to pay your claim, but could be ordered to pay triple the amount to you, personally as a penalty for the bad faith. It could fairly be argued that putting the burden of translation on you is unreasonable and unfair and constitutes bad faith because it is so burdensome that it would effectively prevent you from pursuing the claim. The courts would not likely allow the insurance company to do this to you. So, the bot***** *****ne is that translation is not your responsibility, unless the policy specifically requires it (don't take the insurance adjuster's word for it) and the policy is very unlikely to have such a provision.
