Ex wife has primary and we have joint legal in Indiana. Got the final decree about a year ago. We have a hearing coming up in April for some violations on the court order by my ex, and also that she hasn't paid her share of some of the costs related to the children. Recently she sent me an email asking for my share of expenses incurred on extra curricular activities. Per the court order, we are supposed to share this equally. However, she has not provided the receipts. Out of 10 activities, she has attached one receipt by email but wants payment for all of them. Please advise how to respond to her? Thanks.
