Ex filed for support modification based on his claims of his reduced income; my increased income; reduction in daycare costs. At conference, his income was same, mine had not increased, and after school daycare was less, but summer care increased. Summer daycare used to be included in monthly support but was removed by hearing officer and he is to pay a set percentage towards summer costs. He is refusing. DR hearing officer stated to file for de novo. Do I have to produce more documents if asked by his attorney? Can I request more documents from him? He clearly hides money from his business as his income is poverty but his lifestyle lavish.
