In the course of criminal proceedings, the victim has the right to file an incidental civil action. Moreover, Article 77 of China's Criminal Procedure Law stipulates that if the victim suffers material losses due to the defendant's criminal behavior and the state or collective property suffers losses, the people's procuratorate may bring an incidental civil action when it brings a public prosecution. When necessary, the people's court may seal up or detain the defendant's property.
As long as the criminal act causes material losses, it can bring an incidental civil action, so it is incorrect to say that the crime of arson cannot be incidental to civil action.
I suggest consulting a lawyer, after all, be professional.
