That may not be complete answer. Order appears to say Dads custody ends when EX returns from Iraq.
But what does that order or a prior order which is not extinguished say as to who has custody absent the Iraq issue?
In short who has custody by order if Mom is NOT deployed to Irag?
If order says Mom then so be it! But what actually does it say?
That probably counts as the starting point.
Its NOT up to kid to make up his own rules!
