Lawyer: Yes or No?

moin, I have an urgent question: do I have to pay my lawyer for the opposing insurance, even in case of a minor damage at the kfz, but a present person’s damage (pain money)? I have read about damage at the kfz, the insurance only pays a lawyer above the bagatell border (about 700 euro). our car is still in the workshop. so far it is probably a bagatell damage (felgen/reifen). the track will only be measured tomorrow and there can be some crookedness…. background: my girlfriend had an unindebted accident with our car at the end of the week. the opponent of the accident and his insurance have confessed her fault. my girlfriend was unable to work the morning after the accident and the beginning of the week with 2 doctors. diagnosis: cervical spine distortion after hurling trauma and slight brain shake = 1 week. should/must I take a lawyer to make claims for pain money?
