Is it necessary to ask a lawyer to get a letter of understanding in tort cases?

Please. According to the inquiry of China Travel Service. Surrender, restitution and understanding are statutory mitigating circumstances. The letter of understanding is the victim's understanding of the defendant, which needs the victim's signature. Lawyers can help both parties mediate. If you are suspected of a criminal offence and have been detained, you should entrust a professional lawyer as soon as possible.
