Let's see:
Judge: Mrs xxx, is there anything else?
Mrs. xxx: Yes, he has property somewhere else that he hasn't disclosed, but I don't know where it is nor do I have any evidence to support that allegation.
Judge: Mr. xxx, is that true?
Mr. xxx: No, your honor. I have no other property.
Sorry, but the judge isn't going to throw him in jail after that exchange. if she has any evidence to back her claim, he might. But the judge will not normally throw someone in jail simply because the other party suspects that there might be other assets. If that were the case, every divorced person in this country would be in jail.
Yes, you might find a case somewhere where this seems to be the case. First, I would state that I would not rely on a single case in setting strategy. There are lots of cases where judges have erred - but that doesn't mean you should assume that they will ALWAYS make the same error. Second, if the judge did throw someone in jail after the above exchange, there was likely some reason not to believe the denial.
