Without help from the professional lawyer, you will not predict what may happen. You may apply for the amount lower than you actually deserve as a victim. If you refuse to hire a lawyer, you risk wasting your money on trial uselessly. It is often way better to find a good expert and pay them than obtain no compensation at all. Be aware that an auto accident lawyer may ask you to pay up to 30% of the amount that you manage to claim. Sometimes, if you need some paperwork to be done or representation in court, such experts may insist on hourly payments.
