Legal objectivity:

First, how to write a letter of understanding for traffic accidents. The criminal letter of understanding itself has no fixed format. The purpose of issuing letters of understanding is to reduce the punishment of criminal suspects, and some can release criminal suspects on bail pending trial. Therefore, the letter of understanding is sent by the victim to the criminal's family, and is generally handled by the responsible lawyer for the criminal suspect. However, if the circumstances are minor and you don't need to hire a lawyer, you can refer to other letter of understanding formats. A criminal letter of understanding generally refers to a written document of a legal nature issued by the victim when the victim and the criminal suspect or their families reach a settlement on the outcome of a criminal case. The letter of understanding is generally completed in the process from public prosecution to court cross-examination, and has the effect of discretionary mitigation and lighter punishment in criminal law. If the premise of the letter of understanding causes harm to the victim, it shall be stated that the compensation has been reached and the actual compensation has ended. If there is no harm to the victim, it may not be said, but the focus of the letter of understanding should clearly indicate that the victim has understood, and the victim requests to be exempted from investigating the criminal responsibility of the defendant, that is, the criminal suspect. Therefore, if you are a victim, you should pay attention to compensation when signing the letter of understanding, as well as the effectiveness and notarization of the letter of understanding. Second, according to the law, according to Article 15 of the Criminal Procedure Law of People's Republic of China (PRC), criminal suspects and defendants voluntarily confess their crimes truthfully, admit the alleged criminal facts, and are willing to accept punishment, which can be treated leniently according to law.
