Quick answer
Onbello has line-by-line guides to sixteen family law forms. For California: FL-300 Request for Order, FL-320 Responsive Declaration to Request for Order, and FL-150 Income and Expense Declaration. For Florida: Form 12.905(a) Supplemental Petition to Modify Parental Responsibility, Visitation, or Parenting Plan/Time-Sharing Schedule, Form 12.903(e) Answer to Supplemental Petition, and the Family Law Financial Affidavits, Form 12.902(b) (Short Form) and Form 12.902(c) (Long Form). For Michigan: FOC 87 Motion Regarding Custody and FOC 88 Response, FOC 65 Motion Regarding Parenting Time and FOC 66 Response, MC 416 Uniform Child Custody Jurisdiction Enforcement Act Affidavit, and CC 320 Domestic Relations Verified Financial Information Form. For New York: General Form 17 Petition (Custody, Visitation), GF-40 Petition for Modification of Order of Custody or Visitation, and GF-41 Petition for Enforcement of Order of Custody or Visitation Made by Supreme Court or Family Court. Each guide walks the form in the order the items are printed, and for every box it says what the form asks for, what goes in it, and the common mistake filers make. The item numbers and headings are the ones printed on the official form. The guides are free to read, and Onbello is not a law firm.
