If one of the parties does not believe that the other individual is being forthcoming, there are a variety of discovery tools that can be used. The most common tools include interrogatories. Matrimonial-interrogatories are Supreme Court-approved questions that are asked in most divorce cases that issue discovery. One could also use another discovery tool called a notice to produce, in which one can request documents from the other side. They can ask for bank statements, credit card statements, or maybe loan applications in order to take a look at the physical documents that might be relevant to a case.
