This depends on whether it is run in the name of an individual or a family. If it is operated in the name of an individual, only his personal property can be enforced. Personal property is not only registered as his own, but also includes the property owned by him and his family, for example, the property referred to in the property ownership certificate registered in his name.
There is no so-called property ceiling for court enforcement. As long as it is a fine (including late payment), the court can enforce it.
Of course, when enforcing the law, we should take good care of the property necessary for life.
