Consult the relevant labor contract judgment, the court will not execute it and become the defendant of the enterprise.

1: According to your description, your father was at fault for the employee's work injury, but it was not the direct cause of the work injury. In addition, the enterprise has no clear management system (it can be forged later). So I don't think your father is responsible for the work-related injury, so he doesn't need compensation. It is suggested to go to the local people's social security bureau to mobilize the materials for work-related injury identification to see if there is any useful evidence;

2. From the description, the enterprise should have carried out litigation preservation, secured by real estate, and frozen the execution funds. There is no problem in procedure. If you need money urgently, you can report to the court to explain the situation, provide other property such as real estate as a substitute, and take out the execution money;

3. If it is litigation preservation, it can only be handled in accordance with Article 2.

We should pay attention to collecting evidence in the lawsuit and don't talk nonsense. Enterprises should have no chance of winning, but be careful of black-box operation. I wish you success!
