Starlifter,

So if I am reading your post correctly, you live in WA your Ex moved back to WA and your 18yr old daughter lives and is a KY resident?

Q#1 What state has has jurisdiction? WA or KY? Was the original order in WA and your EX moved to KY at a later date? Did she ever file for a change of venue in order to move jurisdiction to KY?

In NJ the support order is an order compelling the Alternate Parent to support the child. I am assuming your Ex is primary? If WA or KY are the same as NJ your wife does not have an order of obligation to pay support only you do. She can do what ever she pleases without ramification.

If you and your EX are on good terms you or she can file a motion with the court to modify the order. Emancipate the child, amend support and so forth. Even if you are not on good terms you can still file an order to amend the order. Being on good terms with the EX will make it easier to amend as she hopefully wont oppose you in court she will support you? Part of your argument will be your EX no longer supports her as she is in WA.
