Florida Family Law Form 12.984 is the family of Supplemental Petitions that a parent files in circuit court to change an existing final judgment about parental responsibility, time-sharing, child support, or relocation, and it is filed in the same case number as the original divorce or paternity judgment. The form is published by the Florida Supreme Court and is available through the Florida Courts Self-Help Center for any parent who needs to ask a judge to revisit a prior ruling.
A wrong box, a missing UCCJEA affidavit, or a sloppy service of process can sink a modification before the judge ever reads the merits, and the Florida Department of Children and Families 2024 family court report showed that roughly 1 in 4 supplemental petitions statewide are returned, struck, or dismissed because of avoidable filing errors.

What Form 12.984 Is and Who Must File It
Florida Family Law Form 12.984 is not one form but a family of supplemental petitions authorized by the Florida Supreme Court and indexed in the Florida Family Law Rules of Procedure Forms. Each variant lets a parent ask the same circuit court that issued the original final judgment to change one specific part of that judgment because life has changed since the ink dried.
The five core variants are 12.984(a) Supplemental Petition to Modify Parental Responsibility, Visitation/Time-Sharing Schedule, and/or Parenting Plan, 12.984(b) Supplemental Petition to Modify Child Support, 12.984(c) Supplemental Petition for Temporary Modification of Child Support, 12.984(d) Supplemental Petition to Modify Other Final Judgment or Order, and 12.984(e) Supplemental Petition for Modification of Parenting Plan/Time-Sharing Schedule and Other Relief Due to Relocation, governed by Florida Statute §61.13001.
Anyone with an existing Florida final judgment for dissolution of marriage with children, paternity, or supplemental relief can file 12.984. That includes mothers, fathers, legal guardians, and in some cases the Florida Department of Revenue Child Support Program when public assistance is involved. The most common revision dates currently in circulation are the 2015 and 2023 revisions, and you should always confirm the date stamped at the bottom-left of the form before filing because clerks reject older versions.
The agency that receives the form is the Clerk of the Circuit Court in the county that issued the original judgment, and the legal authority that requires it is Florida Statute §61.13 for parenting and §61.14 for support. The penalty for filing in the wrong county is dismissal for improper venue, and the penalty for skipping the supplemental petition entirely and asking for changes by motion is that the judge has no jurisdiction to grant the relief at all.
Before You Start: Documents and Information You Need
The Florida courts expect you to walk in already knowing your case number, your prior judgment date, and the precise change you want. The Eleventh Judicial Circuit Family Division reports that pro se filers who skip pre-filing prep are three times more likely to face a struck pleading.
Gather these items before you open the form:
- The certified copy of your final judgment — without it you cannot quote the exact language you want changed, and the judge will not modify what you cannot identify.
- Your case number from the original case — the clerk files the supplemental petition under the same number, and a wrong number creates a brand-new case that lacks jurisdiction.
- The current parenting plan or time-sharing schedule — you must attach or reference the existing plan so the court can see what is being modified.
- A completed UCCJEA Affidavit Form 12.902(d) — required in every case involving children under the Uniform Child Custody Jurisdiction and Enforcement Act, and missing it triggers automatic dismissal of any custody-related claim.
- A current Family Law Financial Affidavit (Form 12.902(b) or 12.902(c)) — required for any modification touching support, and the short form applies if your gross annual income is under $50,000.
- Proof of the substantial change in circumstances — pay stubs, school records, medical records, or police reports that document why you need the change, because Florida law requires the change be substantial, material, and not contemplated when the original order was entered.
- Filing fee or fee waiver — most counties charge $50 for a supplemental petition under §28.241(1)(a)1.b, and indigent filers should prepare Form 12.902(j) Application for Determination of Civil Indigent Status.
- Current address and contact information for the other parent — service of process under the Florida Rules of Civil Procedure 1.080 cannot happen without it, and bad addresses cost weeks of delay.
- A proposed Parenting Plan (Form 12.995(a)) — if you are asking for time-sharing changes, the judge expects to see your specific proposal, not just a complaint about the old one.
- Your driver’s license or state ID — needed for notarization of the petition’s signature block at the clerk’s office or with a Florida notary public.
Where to Get the Form and How to Access It
The official, current versions of every 12.984 variant live on the Florida Courts Family Law Forms page, maintained by the Office of the State Courts Administrator. Always download from this site rather than a third-party document mill, because outdated forms with retired field numbers are returned by clerks across all 67 Florida counties.
You can access the form three ways. The first is direct download as a fillable PDF from the Florida Courts site, which lets you type entries before printing. The second is paper pickup at your county Clerk of the Circuit Court — for example the Miami-Dade Clerk Family Court Self-Help keeps printed packets on hand. The third is through approved self-help centers like the Florida Law Help portal, which guides indigent users through interactive questionnaires that produce a completed PDF.
The form prints to roughly 6 to 10 pages depending on variant, plus instructions. Read the General Information for Self-Represented Litigants preamble at least once before you write anything, because it lays out the unauthorized-practice-of-law boundaries and the clerk-vs-judge distinction that pro se filers most often misunderstand.
If you are an attorney, you will access the form through your case management software or directly through the Florida Courts E-Filing Portal at myflcourtaccess.com, which auto-pulls the current revision. If you are pro se, the portal also accepts your filings once you create a free self-represented litigant account.
Step-by-Step: How to Fill Out Florida Form 12.984 Line by Line
The walkthrough below uses Form 12.984(a) as the primary spine because it is the most filed variant, and notes where 12.984(b), (c), (d), and (e) diverge. Every field below maps to the field name printed on the official Florida Supreme Court form.
Caption Block — Court, County, and Case Number
The caption sits at the very top of page one. It tells the clerk which circuit court, which division, and which existing case the supplemental petition belongs to.
In plain English, this block asks which courthouse owns your case. To fill it in, write the judicial circuit number, the county name in all caps, the division (usually “Family”), and the case number exactly as it appears on your final judgment. Use MM/DD/YYYY format only where dates appear.
For example, Carlos Rivera writes “IN THE CIRCUIT COURT OF THE ELEVENTH JUDICIAL CIRCUIT, IN AND FOR MIAMI-DADE COUNTY, FLORIDA — Case No.: 2018-DR-014782 — Division: FC-04”.
A nuance: if your final judgment was entered in one county but you and the children have since moved, you may need to file a Motion to Transfer Venue under §47.122 before the supplemental petition, not after.
The most common mistake is using the wrong case number — for example, the post-judgment enforcement number instead of the original DR number — and the consequence is that the clerk opens a parallel case with no underlying judgment, which kills jurisdiction.
A misconception filers carry is that “Family Court” is a court of its own; it is a division of the Circuit Court, and the caption must say “Circuit Court” first or the clerk’s intake screen rejects it.
Petitioner and Respondent Names
The next block names the two parties. The Petitioner is whoever is asking for the change, and the Respondent is the other parent.
In plain English, the form asks who is suing whom. Write each party’s full legal name as it appears on the original final judgment, in standard upper-and-lower case, and never substitute nicknames or married names that were never legally adopted.
For example, Maria Lopez-Ortiz, who divorced under her married name “Maria Ortiz,” writes “Maria Ortiz” in the Petitioner box because that is the name on the 2019 final judgment.
A nuance: if either party has legally changed names since the judgment, attach a certified copy of the name-change order and write both names with “f/k/a” between them, such as “Maria Lopez f/k/a Maria Ortiz.”
The most common mistake is reversing petitioner and respondent because the original divorce listed them the other way; the consequence is that pleadings, service, and the eventual order all reference the wrong party, and the clerk forces you to re-file.
A misconception is that the parent “with custody” must be the petitioner. Either parent may petition under §61.13(2)(c), regardless of who has majority time-sharing.
Paragraph 1 — Jurisdictional Statement
Paragraph 1 says the court has jurisdiction because it entered the original judgment. It is short, but it is the legal hook that lets the judge act.
In plain English, this paragraph says this court already ruled on us, so it can rule again. Fill in the date the original final judgment was entered using MM/DD/YYYY, and confirm that the original case is still pending or that supplemental jurisdiction is retained.
For example, Janet Whitman writes “On 04/12/2014, this Court entered a Final Judgment of Dissolution of Marriage in this case, which addressed parental responsibility and time-sharing”.
A nuance: if the original judgment was entered in another state and later domesticated in Florida, you must plead the domestication order date here, not the foreign judgment date.
The most common mistake is leaving the date blank because the filer can’t find their judgment, and the consequence is that the petition is facially defective and gets dismissed on the respondent’s first motion.
A misconception is that this paragraph “asks for jurisdiction.” It does not — it asserts jurisdiction, and the burden is on the petitioner to plead it correctly.
Paragraph 2 — Residency and UCCJEA Statement
Paragraph 2 tells the judge where the children have lived for the last six months. It is required by §61.514 UCCJEA home-state analysis.
In plain English, this paragraph says Florida is still the children’s home state. Fill in the children’s current address, how long they have lived there, and check the box stating that you have completed the UCCJEA Affidavit Form 12.902(d) and attached it.
For example, Carlos writes “The minor children have resided in Miami-Dade County, Florida continuously since 06/01/2018, a period of more than six consecutive months immediately before the filing of this petition”.
A nuance: if the children have moved out of Florida within the last six months, Florida may no longer be the home state, and you must plead “significant connection” jurisdiction under §61.515 instead.
The most common mistake is forgetting to actually attach the 12.902(d) UCCJEA Affidavit; the consequence is that the entire custody portion of your petition is treated as if it were never filed.
A misconception is that “home state” means citizenship. It is purely about physical residence of the child for the prior six months, not where the parents are from.
Paragraph 3 — The Substantial Change in Circumstances
Paragraph 3 is the heart of every modification. The judge cannot change a final judgment unless you plead a substantial, material, and unanticipated change.
In plain English, this paragraph says something big has changed since the last order, and that change matters. Write a clear, dated description of the change — a job loss, a relocation, a school change, an addiction relapse, a remarriage, or a child’s medical diagnosis — and tie it directly to why the existing order no longer serves the children’s best interests.
For example, Maria writes “Since the entry of the Final Judgment on 09/22/2019, the Respondent has relocated more than 100 miles from the marital residence, has missed 14 of the last 20 scheduled visitations, and has failed to maintain stable employment as documented by attached Exhibit A”.
A nuance: the change must be unanticipated at the time of the original order. A child simply getting older, or a parent’s expected retirement, generally does not qualify.
The most common mistake is writing a vague paragraph like “circumstances have changed” without dates, facts, or attachments; the consequence is a motion to dismiss for failure to state a cause of action under Florida Rule 1.140(b)(6).
A misconception is that any change qualifies. Florida appellate courts in cases like Wade v. Hirschman, 903 So. 2d 928 (Fla. 2005) set a deliberately high bar that mirrors the original best-interests analysis under §61.13(3).
Paragraph 4 — The Specific Modification Requested
Paragraph 4 tells the judge exactly what new ruling you want. Vagueness here is fatal.
In plain English, this paragraph says here is the order I want you to enter. Write the precise change — for example, “Petitioner shall have majority time-sharing during the school year, with Respondent receiving alternating weekends and one weeknight dinner” — and reference the proposed Parenting Plan attached as an exhibit.
For example, Janet writes “Petitioner requests that the Court modify paragraph 7 of the Final Judgment to award Petitioner sole parental responsibility for educational and medical decisions, with shared parental responsibility retained for all other major decisions”.
A nuance: judges cannot grant relief you did not ask for, so if you want both time-sharing and decision-making changes, you must plead both explicitly in paragraph 4.
The most common mistake is asking for “whatever the court deems just” without a concrete proposal; the consequence is that the judge denies the petition because there is nothing specific to grant.
A misconception is that the proposed Parenting Plan is optional. Under §61.13(2)(b), every time-sharing modification requires a proposed plan.
Paragraph 5 — Best Interests of the Child
Paragraph 5 ties your requested change back to the 20 statutory best-interests factors in §61.13(3)(a)–(t).
In plain English, this paragraph says my proposed change is good for the kids. Pick the three to five best-interests factors that most strongly support your case and plead facts under each one.
For example, Carlos writes “The proposed modification serves the best interests of the minor children because (i) Petitioner demonstrates a greater capacity to facilitate a close relationship with the Respondent under §61.13(3)(a), (ii) the children’s school performance has declined since the current schedule began under §61.13(3)(d), and (iii) Petitioner provides a stable home environment under §61.13(3)(e)”.
A nuance: do not list all 20 factors. Judges read these paragraphs quickly and want focused, factual support — not a recitation.
The most common mistake is conclusory pleading like “modification is in the children’s best interests” with no facts; the consequence is that the petition reads as boilerplate and gives the respondent easy grounds for a motion to strike.
A misconception is that the children’s preference controls. Under §61.13(3)(i), the child’s reasonable preference is one factor of twenty, and only when the child is of sufficient age and maturity.
Paragraph 6 — Child Support Modification (12.984(b) and (c) Specific)
For Form 12.984(b) and (c), Paragraph 6 asks for the support change and the financial basis. Skip this section if you are filing 12.984(a) without a support component.
In plain English, this paragraph says child support should go up or down because income has changed by at least 15% or $50 per month, the threshold set by §61.30(1)(b). Write the current support amount, the proposed amount, and the reason.
For example, Marcus, a father reporting his first quarterly modification, writes “Current support is $850 per month. Petitioner’s gross monthly income has decreased from $6,200 to $4,100 due to involuntary layoff on 11/15/2025, justifying a decrease to approximately $540 per month under the guidelines”.
A nuance: temporary modifications under 12.984(c) do not require the 15%/$50 threshold and are designed for short-term financial emergencies under 90 days.
The most common mistake is filing 12.984(b) without attaching the new Family Law Financial Affidavit; the consequence is that the court cannot compute guideline support and the petition is held in abeyance.
A misconception is that voluntary unemployment qualifies. Under §61.30(2)(b), the court will impute income to a parent who voluntarily reduced earnings.
Paragraph 7 — Relocation Pleading (12.984(e) Specific)
If you are filing the relocation variant, Paragraph 7 must include the mandatory disclosures required by §61.13001(3).
In plain English, this paragraph says I want to move with the children, here’s exactly where, when, and why. Write the proposed new address, the date of the move, the reason, the proposed revised time-sharing, and a statement of the financial cost of travel.
For example, Aisha writes “Petitioner intends to relocate with the minor child to 412 Oak Ridge Drive, Charlotte, NC 28202 on 08/15/2026 to accept employment with Atrium Health at a salary increase of $28,000 annually, and proposes that Respondent receive extended summer time-sharing of eight consecutive weeks”.
A nuance: relocation petitions filed without all six mandatory disclosures listed in §61.13001(3)(a) are facially defective and routinely struck on the respondent’s first motion.
The most common mistake is moving the children before the court rules; the consequence is contempt, an emergency pickup order, and a presumption against the move under §61.13001(6).
A misconception is that any move qualifies. Relocation under Florida law means a change of residence more than 50 miles for at least 60 consecutive days, not vacations or temporary stays.
Wherefore Clause and Prayer for Relief
The Wherefore Clause is the closing demand. It restates exactly what you want the court to do.
In plain English, this clause says this is the order I want you to sign. List each requested form of relief on its own line, including modification of the prior judgment, attorney’s fees if appropriate, court costs, and “any further relief the Court deems just and equitable.”
For example, Janet writes “WHEREFORE, Petitioner respectfully requests that this Honorable Court (a) modify the Final Judgment dated 04/12/2014 to award sole educational and medical decision-making authority to Petitioner; (b) adopt the Proposed Parenting Plan attached as Exhibit B; (c) award reasonable attorney’s fees and costs under §61.16; and (d) grant such further relief as is just”.
A nuance: failure to plead attorney’s fees in the Wherefore Clause waives them, even if you would otherwise be entitled under §61.16.
The most common mistake is using a generic “grant all relief” clause; the consequence is that the judge has no roadmap for the final order and you must come back for clarification.
A misconception is that the Wherefore Clause is just a closing formality. It is a binding statement of the relief you are demanding and limits what the court can grant.
Signature, Verification, and Notarization Block
The last page contains your signature, a verification under penalty of perjury, and a notary block.
In plain English, this block says I swear what I just wrote is true. Sign in blue or black ink in front of a notary public or deputy clerk, write your printed name, address, phone, and email, and have the notary complete the jurat.
For example, Carlos signs “Carlos M. Rivera,” prints his address as “1422 SW 27th Avenue, Miami, FL 33145,” and the notary fills in “Sworn to and subscribed before me this 14th day of May, 2026”.
A nuance: Florida allows remote online notarization under §117.201, which lets you notarize the petition by webcam if a paper notary is unavailable.
The most common mistake is signing the petition before reaching the notary; the consequence is that the notary cannot certify the signature and the entire packet must be reprinted and re-signed.
A misconception is that a witness can stand in for a notary. Verifications under §92.525 require either a notary or a written declaration under penalty of perjury — not a witness.
Certificate of Service
The Certificate of Service is the final paragraph confirming that the other parent received a copy of the petition.
In plain English, this section says I gave the other side a copy. List the date of service, the method (e-mail through the e-portal, U.S. mail, or hand delivery), and the recipient’s name and address.
For example, Maria writes “I certify that on 05/14/2026 a true and correct copy of the foregoing was served via the Florida Courts E-Filing Portal upon David Ortiz, Respondent, at dortiz@email.com”.
A nuance: a brand-new supplemental petition usually requires personal service by a sheriff or process server under Rule 1.080, not e-service, because it reopens the case for a new round of pleadings.
The most common mistake is e-filing without arranging personal service; the consequence is that the 20-day clock for the respondent’s answer never starts and the case stalls indefinitely.
A misconception is that a text message or social media DM counts as service. Florida courts have repeatedly rejected informal service even when the respondent admits receipt.

How to File the Completed Form
You have three filing channels in Florida. Each one has a distinct cost, processing time, and proof-of-filing record.
The first channel is the Florida Courts E-Filing Portal, which is mandatory for attorneys and strongly preferred for pro se filers. The fee is $50 plus a small portal convenience charge, payment is by credit card or e-check, and you receive an instant electronic stamp showing case number and time of filing. Processing time from filing to docket is typically same-day or next business day, and you should save the PDF confirmation as your proof of filing.
The second channel is in-person filing at the Clerk of the Circuit Court for the county that issued the original judgment, for example the Orange County Clerk Family Division. The fee is also $50, payment is cash, money order, or credit card depending on county, processing is immediate, and your proof of filing is a clerk-stamped paper copy you take home that day.
The third channel is by mail, which is allowed but slowest. Send the original petition, all exhibits, and a check for $50 made payable to the Clerk of Court, plus a self-addressed stamped envelope so the clerk can return your stamped copy. Processing time is 7 to 14 days, and the postmark does not count as filing — the clerk’s date stamp does.
Service on the respondent is a separate step from filing. Because a supplemental petition opens a new round of pleadings, most circuits require formal personal service by a sheriff (typically $40) or a private process server ($50–$100). The respondent then has 20 days under Florida Rule 1.140 to file an answer.
If you cannot afford the filing fee, file Form 12.902(j) Application for Determination of Civil Indigent Status at the same time as your petition; the clerk decides eligibility within minutes based on household income under 200% of the federal poverty line.
What Happens After You File
Once the clerk accepts your petition, the case is reopened under the original case number and assigned to the same judge or division when possible. A new case management order may issue within 30 days, setting deadlines for mediation, discovery, and an initial case management conference under Florida Rule 12.200.
The respondent has 20 days to file an Answer (Form 12.903(d)) and may file a Counter-Petition. If the respondent ignores the petition, you may move for default under Rule 1.500, but defaults in family cases involving children almost always require an evidentiary hearing because the judge must still find that the modification serves the child’s best interests.
Most Florida circuits require mandatory mediation before a final hearing, run through the Florida Supreme Court Certified Mediator program. Mediation typically happens within 60 to 90 days of filing and resolves the majority of supplemental petitions without trial.
If mediation fails, the judge sets a final evidentiary hearing where each side presents witnesses, exhibits, and argument. Final hearings on supplemental petitions usually run 1 to 4 hours, and the resulting Supplemental Final Judgment is appealable to the appropriate District Court of Appeal within 30 days.
Mistakes to Avoid When Filling Out the Form
These are the errors that send Florida supplemental petitions to the rejection pile most often.
- Filing in the wrong county — venue lies where the original judgment was entered, and filing elsewhere triggers dismissal for improper venue.
- Skipping the UCCJEA Affidavit — every petition affecting children requires Form 12.902(d), and missing it strips the court of subject-matter jurisdiction over custody.
- Pleading “circumstances have changed” without facts — vague allegations invite a successful motion to dismiss for failure to state a cause of action.
- Using the wrong case number — supplemental petitions must reuse the original DR number, and a new number creates a parallel case with no jurisdiction.
- Forgetting to attach a proposed Parenting Plan — time-sharing modifications without Form 12.995(a) leave the judge nothing concrete to adopt.
- Filing 12.984(b) without a current Financial Affidavit — the judge cannot compute guideline support without 12.902(b) or (c) and will hold the case.
- Missing the relocation mandatory disclosures — Section 61.13001(3) requires six specific disclosures, and missing any one is grounds for striking the petition.
- Signing before reaching the notary — a pre-signed petition cannot be notarized and must be reprinted entirely.
- Relying on e-service instead of personal service — supplemental petitions reopen the case and require formal sheriff or process-server delivery in most circuits.
- Asking for “all just relief” without specifics — the Wherefore Clause defines the universe of what the judge can grant, and vagueness limits your remedy.
- Listing all 20 best-interests factors without facts — boilerplate pleading reads as filler and weakens the actual factors that support your case.
- Moving children before the court rules on relocation — under §61.13001(6), a self-help relocation creates a presumption against you and risks contempt.
Do’s and Don’ts
These quick rules separate clean filings from rejected ones.
- Do download the form fresh from flcourts.gov every time, because revisions roll out without notice.
- Do read the General Information for Self-Represented Litigants preamble before filling anything in, because it explains the line between clerk and judge.
- Do file in the same county and case number as the original judgment, because that is where supplemental jurisdiction lives.
- Do attach every exhibit — UCCJEA Affidavit, financial affidavit, proposed Parenting Plan, and supporting evidence — at the time of filing.
- Do keep a stamped copy of the petition for your own records, because clerks lose paper filings more often than filers expect.
- Do arrange formal service through a sheriff or process server within 120 days of filing under Rule 1.070(j).
- Don’t use a non-Florida or out-of-date form, because clerks reject non-current revisions on sight.
- Don’t plead facts you cannot prove with documents or witnesses, because the respondent will challenge every unsupported allegation at the hearing.
- Don’t combine multiple variants of 12.984 in one petition, because each variant has distinct service and pleading requirements.
- Don’t serve the petition by text, email, or social media unless the court has explicitly authorized substitute service.
- Don’t pay the filing fee from a third-party account, because some clerks reject payments not drawn on the filer’s own card or account.
- Don’t bypass mandatory mediation, because most circuits will not set a final hearing until mediation has been attempted in good faith.
Pros and Cons of Filing on Your Own vs. With Help
Self-representation saves money, but the legal complexity of modification cases makes attorney help valuable in many situations. Compare honestly before deciding.
Pros of filing pro se:
- You save $3,000 to $15,000 in attorney fees, depending on case complexity, which matters most for filers under financial stress.
- You control the timeline and can file the moment you are ready, without waiting on a lawyer’s calendar or retainer process.
- Florida’s self-help centers provide free packets, fillable forms, and instructional videos specifically designed for pro se filers.
- You learn the system, which pays off if you anticipate future modifications, enforcement actions, or contempt motions.
- Court staff in most counties can answer procedural questions about where to file, what to attach, and what fees apply, even though they cannot give legal advice.
Cons of filing pro se:
- The substantial-change-in-circumstances standard is legally technical, and pro se petitions are far more likely to be dismissed for failure to state a cause of action.
- You will not know which of the 20 best-interests factors carry the most weight in front of your specific judge, which an experienced local attorney usually does know.
- Drafting a proposed Parenting Plan that a judge will actually adopt requires familiarity with workable schedules, holiday rotations, and exchange logistics that surveys show pro se parents often miss.
- Mediation strategy — knowing what to settle, what to fight, and what to trade — is harder without counsel, and rushed settlements often have to be re-litigated within two years.
- Appeals from a supplemental final judgment are extremely difficult to win pro se, because appellate procedure under the Florida Rules of Appellate Procedure is unforgiving.

FAQs
Is Florida Form 12.984 the same as the original divorce petition?
No. It is a supplemental petition filed in the same case to change a final judgment that already exists, not a new divorce or paternity action.
Can I file Form 12.984 in any Florida county?
No. You must file in the circuit court of the county that entered the original final judgment, unless venue has been formally transferred under §47.122.
Do I need an attorney to file Form 12.984?
No. Florida explicitly allows pro se modification filings, but the legal standards are technical and many filers benefit from at least a consultation.
Is there a filing fee for Form 12.984?
Yes. Most counties charge $50 for a supplemental petition under §28.241, plus small portal or service fees, with indigent waivers available through Form 12.902(j).
Do I write my maiden name or married name in the Petitioner box?
Yes — write whatever name appears on the original final judgment, with “f/k/a” if you have legally changed names since.
Does the date in Paragraph 1 mean the date I file or the date of the original judgment?
No. Paragraph 1 always uses the date of the original final judgment, never the supplemental filing date.
Can Paragraph 3 simply state “circumstances have changed”?
No. You must plead a substantial, material, and unanticipated change with specific dates, facts, and supporting documents, or the petition will be dismissed.
Do I have to attach a Parenting Plan if I am only changing time-sharing slightly?
Yes. Any time-sharing modification requires a proposed Parenting Plan on Form 12.995(a) under §61.13(2)(b).
Is the UCCJEA Affidavit really required if the children have always lived in Florida?
Yes. The affidavit is required in every case involving children, regardless of how long they have lived in Florida, under §61.522.
Can I serve the other parent by email or the e-portal?
No. A supplemental petition reopens the case and almost always requires formal personal service by a sheriff or process server under Rule 1.080.
Will the judge automatically grant my petition if the other parent does not respond?
No. Even on default, the court must still find by competent evidence that the requested modification serves the children’s best interests.
How long does a Form 12.984 case take from filing to final order?
Yes — most cases resolve in 4 to 9 months including mediation, with contested final hearings adding another 2 to 6 months depending on docket congestion.
Can I withdraw a Form 12.984 petition after filing?
Yes. You may file a Notice of Voluntary Dismissal under Florida Rule 1.420(a) at any time before the court rules on the merits, though the filing fee is not refunded.
Is the $50 supplemental petition fee the same in every Florida county?
Yes — the base statutory fee is $50 statewide under §28.241, although counties may add small surcharges for technology and service.
