When facing a modification or establishment of court orders related to family law in California, the FL-300 Request for Order form becomes a critical document. This form is typically necessary when a party needs to request the court to make specific orders for child custody, visitation, child support, spousal support, or other family-related matters. - Before filing the FL-300, parties may need to complete an **Income and Expense Declaration (FL-150)** to provide financial information. - A change in circumstances, such as a job loss or relocation, often triggers the need for an FL-300 form to request a modification of existing orders. - Initial filings like the **Petition for Dissolution (FL-100)** may precede this form if it's the first instance of action. In summary, the FL-300 is a pivotal form utilized during various stages of family law proceedings to facilitate fair and relevant adjustments or introductions of legal orders. Its submission is generally prompted by notable life changes impacting existing family law arrangements or initial needs for such determinations.
