Child support, maybe. I don’t know the regs/law there. (I’m not an attorney).
As far as alimony and/or property distribution goes, those rights are (usually) extinguished after the divorce is granted, or the defendant answers and does not file a counterclaim for those.
There are a few very limited exceptions to the above rule, but most divorcing couples won’t encounter those. (Service by publication and divorce where the court lacks personal jurisdiction over the absent spouse are the two that come to mind.)
