During our custody battle, my ex (since 2005) sent interrogatories with the child support case file number. There was a review for child support and a determination to increase was made, but then the case was stalled due to a "barrier" which would appear to be the interrogatories. If there is no hearing scheduled, must I answer the interrogatories? Child support office thinks this is a custody matter but custody papers were signed and filed a month ago. Any help will be greatly appreciated!
