If, as you indicate, the original child support order was out of Nevada, it is possible (but not certain) that you can get an order of reimbursement, essentially on the basis of fraud, since the e-mail you speak of states that there was no such expense when the original order was made.
NRS 125B.080 states in part that "Any inaccuracy or falsification of financial information which results in an inappropriate award of support is grounds for a motion to modify or adjust the award." Whether that statute can be used to obtain a retroactive adjustment and order of reimbursement has not been clearly established by the case law.
You need to bring the original court order, all orders altering or adjusting it, and any relevant correspondence -- including that e-mail -- to a family law specialist who knows child support law. For background, you might want to see the materials we have posted at http://willicklawgroup.com/child-support/.
