2. Make your claim clear (the amount of compensation and the legal basis of each item).
3. Be sure to prepare all kinds of evidence (such as hospitalization slip, salary slip, accident certificate, etc.). )
4. Think about how the other party will refute before the trial, and then make countermeasures.
In fact, if it is serious, I suggest you hire a lawyer (even if you don't invite him to court, you can ask him to help you make a list of compensation amount and related basis). After all, lawyers are experienced and know how to fight for the best interests of the injured party. Especially in traffic accidents, some experienced lawyers can help you get high compensation.
