When will the letter of understanding become legally effective? How should I write it properly?

1. Under what circumstances does the letter of understanding have legal effect?

Before filing a case.

Before the public security organs deal with it.

Before the trial.

The letter of understanding must finally appear in court and be seen by the presiding judge, but the procedure should be that I first write it and give it to the case-handling unit, and then the case-handling unit will put the written letter of understanding into the criminal suspect's file bag. If the police feel that the criminal evidence is sufficient, they will hand it over to the people's procuratorate soon after approving the arrest.

Second, how should I write it properly?

Model letter of understanding

On xx, XX, XX, Zhao had an argument with me, and Zhao slightly injured me. After the incident, Zhao xx surrendered himself to the public security organ on xx, XX, XX, XX. Now the case has been transferred to Dali People's Procuratorate for review and prosecution, and Zhao XX is detained in Dali Detention Center.

After the accident, Zhao XX's family attached great importance to it, and immediately paid Zhao XX the victim's medical expenses of 15200.00 yuan, and then actively negotiated with my family for further compensation, and paid all the compensation of 35,000.00 yuan according to the standard stipulated by law.

During the negotiation, we learned that Zhao XX's family is also very difficult, and the main income is to rely on meager agricultural cultivation and go out to work. In this difficult situation, Zhao XX and his family are still actively raising compensation money for compensation. We think his repentance is very good, and his relatives also need the help of his work income. Zhao XX's intentional injury caused us great pain, and so did his family. He has learned his lesson. We don't want to continue to create new tragedies and are willing to forgive him.

Extended data:

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. But if the circumstances are minor and you don't need to hire a lawyer, you can refer to the format of this letter of understanding.

If the premise of the letter of understanding causes harm to the victim, it shall be clearly stated that the compensation has been reached and the actual compensation has ended. If there is no harm to the victim, there is no need to express it, but the focus of the letter of understanding should be clear that the victim has understood and the victim requests to be exempted from investigating the criminal responsibility of the defendant (criminal suspect).
