A signed confession can be changed. If there are omissions or errors in the records, the criminal suspect may supplement or correct them. After the criminal suspect admits that the record is correct, he shall sign or seal it. Confession refers to the confession made by a criminal suspect about his guilt or guilt, or his excuse of innocence or guilt. Confession and excuse are both important parts of confession.

Legal basis:

Article 122 of the Criminal Procedure Law

The interrogation record shall be handed over to the criminal suspect for verification. If there is no reading ability, it shall be read out to the criminal suspect. If there are omissions or errors in the record, the criminal suspect may make additions or corrections. The criminal suspect shall sign or seal his name after admitting that it is correct in the record. Investigators should also sign the records. If a criminal suspect asks to write a confession himself, it shall be allowed. When necessary, investigators may also ask the criminal suspect to write a confession in person.
