In the past, my ex was late on child support for 5 months, late on reimbursing me. He is current now with the exception of unpaid airfare. However; he fails to call me to let me know that our child arrives a few times (flys as unaccompanied minor) per our court order. He has never consulted me prior to taking our child to doctor's or ER. The only way, I knew is that he used my insurance and I saw it on a bill. Is there a timeframe deadline for these types of issues?
