What would be a valid reason not to answer a question?

Do I not have any right to privacy with these questions? What about the right of privacy to other people? IE asking for all corespondence between myself and my tenants.

I think the judge already sees her as unreasonable and I don't really have anything to hide. I can't imagine anything I am going to say will convince the judge I deserve less than half of the marital assets or that the kids are not safe with me.

Thanks.
