FL-365 is a California family court form used when you need to respond to the other party’s request to set aside, or cancel, an existing child support, spousal support, or partner support order. When someone asks the court to overturn a support order—usually claiming mistake, fraud, lack of notice, or newly discovered evidence—the court gives you an opportunity to formally present your side. FL-365 is the document that allows you to explain whether you agree or disagree with the request and why. Without submitting this form, the judge may make a decision based solely on the other party’s statements.

This form gives you a structured way to provide your explanation of the facts, correct inaccuracies, and supply your own evidence. You can detail why the order should remain in place, why the request to set it aside is not justified, or whether you believe some parts of the support order need review. Because support orders directly affect financial responsibilities for both parties, the court relies heavily on the information provided in this response when evaluating whether the original order should be changed.

FL-365 also allows you to attach supporting documents such as financial records, pay stubs, proof of service issues, written communications, or any other evidence relevant to the arguments raised in the request. Since the form is a signed declaration under penalty of perjury, the information you include must be truthful and complete. The accuracy of your statements matters, as the court uses this form to determine whether the prior support order was unfairly entered or if it should remain legally binding.

After filing FL-365, the judge reviews both sides’ information before making a ruling. Your response helps ensure the court sees a balanced view of the situation and understands any context that may have been missing from the original application. This is your chance to protect your rights, clarify misunderstandings, and provide the court with facts that support your position.

Overall, FL-365 is an essential part of the legal process when a support order is challenged. It ensures your voice is included in the court’s decision and allows you to present a clear, documented response before any changes are made. Properly completing and filing this form can significantly influence whether the court decides to uphold, modify, or set aside the original support order.
