What do I do to get the court's attention if my ex wife isn't following the conditions of her court order?

I always recommend that the parties try to talk things out, especially if it is a custody matter since it doesn't help the children for their parents to be fighting things out in court. However, it sounds from your question, that you're past the talking things out stage.

Filing a contempt petition is the proper way to get the court's attention about your wife's failure to obey the court's orders. Although it would be ideal if you had an attorney to represent you, many people have to represent themselves in divorce and custody proceedings because they can't afford a lawyer. The Oregon Judicial District has prepared forms for people representing themselves (also referred to as "acting pro se"). I've included a link to the contempt forms below.

A lot of the county courts in Oregon, including Marion County, have a Family Law Facilitation Program to help people who are acting pro se in family court -- people can get information about what papers to file and, sometimes, get their filled-out forms reviewed. I've also included a link to a county-by-county contact list for the Faciliation Programs.

Good luck!
