Arnold Schwarzenegger has filed his response to Maria Shriver's petition for divorce, and documents show he doesn't want to give Shriver any spousal support.

Maria asked for support in her petition.

Another difference in filing: Maria wants Arnold to pay for her attorney fees -- he says each party should pay their own.

Still, there was one plus side from the filing -- both want joint custody of their children.

The couple does not have a prenuptial agreement. Hopefully their joint custody choice proves that they can put their money differences aside for their family. With about $400 million at stake, things could get ugly.
