If a party does not have the funds to pursue discovery, they may want to consider seeking an order from the court for payment of lawyer fees and costs from joint funds or from the separate property of the other spouse.
Most states have divorce laws that authorize awards of fees and costs necessary to permit a party to litigate properly in certain circumstances. Additionally, if you propound discovery and your spouse does not thoroughly respond, you may have a cause of action against them for sanctions (mandatory fees and costs).
