I live in Neveda. Child lives in California. We both agree to let childa remain in California. Can we put that in the petition for divorce in Neveda?

Not (quite) enough facts.  See the discussion of exactly that question in the article "The Basics of Family Law Jurisdiction" posted at http://www.willicklawgroup.com/child-custody-and-visitation/.  If you have further questions, consult with a family law specialist who understands jurisdictional matters.
