OP, the reality of family law is that default judgments are very frequently are re-heard. The reason for that is because no matter what the situation is, most of the time a judge really cannot make a fair decision that is truly in the best interests of the children unless they hear testimony and see evidence from both parties.
So yes, its very possible that your case will be reheard. You may very well still get the same result anyway, but its not guaranteed at all. You have an attorney. Talk to your attorney about the situation.
