What if the lawyer has to pay some fees? What if the lawsuit is lost?

First, you can refuse him. Nowadays, many unscrupulous lawyers charge management fees in order to manage themselves.

Second, some judges are not of high quality and may be biased in judging cases, but the law is there and they dare not blatantly reverse black and white;

Three, if the case is unfair, there is a second trial, you can appeal according to the procedure, and ask the court of second instance to make a fair judgment.
