In case of a traffic accident you are entitled to a legal representation for presenting your compensation claim. 

You can claim compensation for material damages (damages to your car) and immaterial damages (injury).

The cost of the legal representation is carried by the opponent or rather his compulsory car insurance, if the accident was caused by the opponent.

In case of an injury it is of utmost importance to immediately - on the same or the following day of the accident - having your injuries examined by a doctor.
