how do I go about getting an order forcing my wife to disclose here financials in new york?

All relevant financial information is discoverable in a matrimonial action, and each party should turn their records over to the other party without need of discovery demands. However, if you are not getting the information voluntarily, you need to serve discovery demands, and if they are not complied with, make a motion to compel. A motion for a forensic accounting may be necessary to determine if illegal transfers were made. Depending on the scope and type of documents that are involved, computer records should be included in the demand/motion.
