The money sent by the work unit was taken by colleagues who refused to admit it. How do they claim compensation?

1, I think the unit and Li should be listed as * * * co-defendants, requiring them to bear joint and several liabilities. The unit has a major fault in distributing money to the impersonator without justifiable reasons; Li's accepting money from others under an assumed name constitutes unjust enrichment in civil and may constitute a crime in criminal (but the money is not necessarily intentional by the public security). Both the unit and Li violated your mother's rights and interests, so it is safer to list them as * * * together with the defendant.

2. The amount claimed plus the interest for these years. At the same time, you can claim the transportation, accommodation, meals, lawyer's fees and lost time expenses spent on recovering the money, and you can ask the defendant to bear the legal costs. The possibility of mental damage support is very small.

3. Of course, civil compensation is established. As for criminal proceedings, it can also be established strictly, but now such a society is nothing, so let the defendant pay more compensation according to civil cases.

Of course, it is necessary to imitate the signature. This is evidence; You can ask the court to make an appraisal. Of course, the more detailed the evidence, the better It is best to get the original signed by Li, and you can apply to the court to prevent the unit from tampering.

You don't need to assign responsibility to them, just let them bear joint liability directly, and let the court or let them solve the rest themselves. Joint liability will protect you more.

As far as your explanation is concerned, if you provide sufficient evidence, you will certainly get support. Remind the limitation of action: bring a lawsuit within two years from the date when you know or should know that your rights have been infringed, otherwise you will not have the right to win. So sue to the court as soon as possible.

I hope I can help you.
