FL-280 is a California family court form used when a parent or alleged parent wants to set aside (cancel) a Voluntary Declaration of Paternity (VDP). A VDP is a legal document that establishes parentage without going to court, often signed at the hospital when a child is born. Once filed with the state, the VDP has the same legal effect as a court order. FL-280 allows a party to challenge that declaration if they believe it was signed by mistake, under fraud, duress, or based on incorrect information—most commonly mistaken paternity.

The form is used to request a court hearing where a judge will review whether the declaration should be set aside. California law provides only limited timeframes for challenging a VDP—generally within two years of the child’s birth, or within two years of discovering certain relevant facts (such as genetic test results). FL-280 requires the applicant to explain the legal and factual basis for the request, including why the declaration should be canceled and what evidence supports the claim. Supporting documents such as DNA test results, communications, or witness statements may be attached.

FL-280 is also used to notify the other parent and all required agencies—such as the Local Child Support Agency (LCSA)—that the applicant is challenging the existing legal parentage determination. Because setting aside a VDP can affect child support, custody, visitation, and the child’s legal rights, the court must carefully evaluate the request. The form ensures that all relevant parties receive proper notice and have an opportunity to respond before the court makes a decision.

At the hearing, the judge will consider whether the VDP was signed voluntarily and knowingly, and whether statutory grounds exist for setting it aside. The court may also order genetic testing if paternity is in question. FL-280 places the burden of proof on the person requesting the change, and the judge’s decision will determine whether the VDP remains valid or is rescinded. If set aside, the child’s legal parentage status will need to be re-established through the appropriate legal process.

In summary, FL-280 is an essential form for anyone seeking to challenge or overturn a Voluntary Declaration of Paternity in California. It triggers a court review, ensures proper notice, and allows the applicant to present evidence supporting their request. Because a VDP carries significant legal consequences, FL-280 provides a structured and lawful way to correct mistakes or address concerns about the accuracy or validity of the original declaration.
