FL-360 is a California family court form used when a party wants the court to set aside (cancel, overturn, or reopen) an existing child support, spousal support, or partner support order. Support orders can be set aside only under specific legal grounds—such as fraud, mistake, lack of notice, perjury, or newly discovered evidence. FL-360 allows the requesting party to explain why the original support order was entered unfairly or inaccurately and to formally ask the court to reexamine the case. Filing this form begins the legal process for challenging the existing support order.

The form requires the applicant to state the legal basis for the request and provide a detailed explanation of the facts that justify setting aside the order. This may include examples such as not being properly served with court papers, not attending a hearing due to circumstances beyond one’s control, discovering hidden financial information, or relying on incorrect numbers when support was calculated. FL-360 gives the court the necessary information to determine whether the order should be revisited under California Family Code sections governing set-aside requests.

Because support orders directly affect financial obligations and enforcement actions such as wage garnishment, the court requires strong evidence to support a set-aside request. FL-360 must often be accompanied by supporting documents like pay stubs, tax records, communication logs, proof of service issues, or any newly discovered evidence. The accuracy and completeness of the information provided are crucial, as the judge uses this information to decide whether the original order should be reopened or corrected.

FL-360 also serves as a request for hearing, which means the court will schedule a hearing date where both parties can present arguments. The other party must be properly served with the application, ensuring they have notice and an opportunity to respond—typically using FL-365 (Responsive Declaration to Application to Set Aside Support Order). At the hearing, the judge will review evidence, consider the legal grounds for the request, and decide whether to deny the application, modify the order, or set it aside entirely.

In summary, FL-360 is an essential tool for anyone seeking to challenge or overturn an existing support order in California. It provides the court with the legal and factual basis for the request, triggers a hearing, and ensures both parties have an opportunity to be heard. When completed thoroughly and supported with proper documentation, FL-360 helps the court determine whether justice requires reopening or correcting a support order.
