My Wife Filed For Divorce. I Didn't Appear In Court. It Is Now Final.
Do I Have Any Recourse To Get Things Overturned? (spousal Support Or Custody).

Now is not a good time, and I am not sure that the judge will allow for an appeal or a motion to admend, right after you did not show up.

If you can show the court there was a good reason not to show up, in the hospital, ill, in jail, some reason, besides just not caring enough to show up.

You can hire an attorney and try and file a motion to admend the ruling.
