A MyDivorceCalc coordinator can discuss questions and next-step logistics, but cannot give legal advice. Using this site, running an estimate, or submitting a form does not create an attorney-client relationship. If you want legal advice, an independent Arizona-licensed family law attorney is the right person — bring your estimate to that conversation.
