I have been alienated from my kids for 4 months now. No contact of any kind. I get them tonight. What can I file to keep them? Alienation is abuse.

There is an emergency process to ask the court for very quick hearing.  You would need to file this in the county where the children are currently located.  Unfortunately, I do not believe there are any pro se forms for this process, so you would need to do your own or consult an attorney.  This is a statute that may apply (depending on the facts of your case): https://www.legis.iowa.gov/docs/code/598B.204.pdf     DONNA R.
