Everything you need to write a declaration letter to the judge in your custody case: an example, a downloadable template, an outline and tips. To respond to a Petition for Custody and Support, your first step is to fill out a Response form.This tells the court how you want custody and support handled. This case cover sheet is required so that the court can assign your case to the correct district for filing and hearing. It satisfies the requirement. This guide is designed to help you fill out the forms yourself. It is not intended to provide legal advice nor strategy as to how to complete the case. This guide will take you through both of these processes, guiding you on which forms you need, how to fill them out, and how to start the filing process. I would like to send a letter via USPS. You can request a change of judge in a child custody case as your local rules allow.
