How do court appraisal companies choose the right appraisal company?

Generally not, because the court's appraisal companies are all decided by lottery, and they cannot be designated, mainly because they are afraid of communicating (colluding) with the appraisal companies here. You can propose to draw lots again.

Nor can we designate any large judicial evaluation company, because it is mainly entrusted by the judicial department, so the court will evaluate whoever wins the lottery.
