2. They have the right to sue you and they might as well as get a judgment agaist you, by then, you probably have to pay their lawyer fees too.
3. More ever, if the case has been brought it to court already, the best thing you have to do now is just pay and make a settlement with them. the reason is once you got a judgment, it will become a public record and might not do good for your personal credit, it doesn't matter that how much money has been involved.
4."我們心理不平衡, 當然拒絕執行了"--if you tell this to the judge, i am sure that you already lost the case.
Good luck
