How to Change a Child’s Last Name in Florida: Complete Legal Guide

Contact me, Mark E. Sawicki, to discuss next steps and how to protect your rights before you move forward with a child’s last name change in Florida.

Florida Child Name Change: Filing the Right Petition

To change a child’s last name in Florida, a parent must file a Petition for Name Change of Minor Child (Form 12.982(b)) in the circuit court of the county where the child lives. The petition must include the child’s current and proposed name, the reason for the change, and both parents’ information. A certified copy of the child’s birth certificate is also required. Contact Mark E. Sawicki, P.A. to make sure your petition is filed correctly the first time.

How to Change a Child’s Last Name When Both Parents Agree

When both parents agree on the name change, the process is much faster. The non-requesting parent signs a notarized consent form, and in many Florida counties the court can approve the petition without a hearing. The typical timeline when both parents agree is 6 to 10 weeks from filing to the court’s Final Order. Mark will prepare all paperwork and coordinate with the court to avoid unnecessary delays.

How to Change a Child’s Last Name Without the Other Parent’s Consent

If one parent objects to the name change, Florida courts will schedule a hearing where a judge decides based on the best interest of the child. Courts consider the child’s relationship with both parents, the reason for the change, and — for older children — the child’s own preference. The timeline in contested cases is typically 12 to 20 weeks. Mark has extensive experience presenting these cases persuasively.

Required Documents for a Florida Child Name Change

To successfully change a child’s last name in Florida, you will typically need: a completed Form 12.982(b), a certified copy of the child’s birth certificate, a notarized consent from the other parent (if agreeable), proof of service if the other parent is contesting, and the court filing fee. Mark ensures your documentation is complete, accurate, and filed correctly so your case moves forward without rejection.

How Long Does a Child Name Change Take in Florida?

The timeline depends on whether both parents agree. With mutual consent: 6–10 weeks. If one parent contests: 12–20 weeks or more, depending on court scheduling. Background checks are not required for minors, which eliminates one common delay. Contact Mark E. Sawicki, P.A. to discuss your specific timeline.

Do both parents need to agree to change a child’s last name in Florida?

In most cases, yes — both parents must either consent or be properly notified. If both agree, the court can approve without a hearing. If one parent objects, a judge decides based on the best interest of the child. Exceptions apply if a parent’s rights have been terminated or the parent cannot be located after a diligent search.

What form do I need to change my child’s last name in Florida?

You need Florida Family Law Form 12.982(b) — Petition for Name Change of Minor Child. File it in the circuit court of the county where the child lives. You also need a certified copy of the child’s birth certificate and, if both parents agree, the other parent’s notarized consent. Mark will ensure your paperwork is complete and correctly filed.

How long does a child name change take in Florida?

With both parents’ consent, a child name change typically takes 6 to 10 weeks. If one parent contests, the process takes 12 to 20 weeks or longer, depending on court scheduling. Background checks are not required for minors, removing one common source of delay.

Can a judge deny a child name change in Florida?

Yes. Florida judges can deny a child’s name change if it is not in the child’s best interest. Courts consider the child’s relationships with both parents, the reason for the change, and the child’s own preference (if old enough). Working with an experienced attorney like Mark significantly improves your chances of approval by presenting the case correctly.
