What waiting costs

A Florida judge cannot go back and fix the months you didn't file.

In Florida, a change to child support generally reaches back only to the date the supplemental petition is filed — not to the day your circumstances actually changed. Every month the paperwork sits on your kitchen table is a month you don't get back.

Paying an amount you can't afford

You lost hours, lost a job, or took a pay cut — but the order still says what it said in 2019.

Receiving less than the children need

The other parent's income went up, or the children's expenses did, and nothing has been adjusted.

Filing it wrong and starting over

A blank field, an unsigned page, or a missing notary line is a common reason a clerk sends a packet back.

Why parents use JusticeXpress

Court-approved forms, assembled from your own answers, for $89.

01 / PRICE

$89, all in

One flat fee for the whole package. No hourly billing, no retainer, no subscription. Your county's filing fee is paid separately to the clerk.

02 / CONTROL

You fill it in — not us

You enter your own facts through the questionnaire. Our system places those answers onto the forms exactly as you wrote them. No person decides what goes in a blank.

You answer once. The system carries the same information across every form in the packet, so you're not writing your case number eleven times.

03 / ACCURACY

Clerically checked before it ships

A Florida nonlawyer document preparer reviews the assembled packet against the court's published guidelines for blank fields, spelling and date inconsistencies, and missing signature or notary lines.

Who we are

We've been putting court forms in people's hands since before there was a Google.

Nobody plans to become an expert in family court paperwork. You just need the number changed so you can pay your rent, or so your kids get what a judge already said they were owed.

JusticeXpress Florida comes out of 25 years of building public legal information for self-represented people — work that is now run by a state court system as a service to its citizens. Same conviction, applied here: the forms belong to you, and you shouldn't need $3,000 to fill them out.

“You are allowed to represent yourself in a Florida family court. The paperwork should not be the thing that stops you.”
  • Forms are the official Florida Supreme Court Approved Family Law Forms — the same ones the clerk hands out
  • You supply every fact; the system does the assembly; a nonlawyer performs a clerical check only
  • Operated in accordance with Rule 10‑2.1(b), Rules Regulating The Florida Bar, governing nonlawyer assistance with court‑approved family law forms
  • Written disclosure signed by you and by us before any form is assembled
How it works

Three steps. You stay in control of every one.

STEP 01

Register and sign the disclosure

Before anything is assembled, you receive and sign the Disclosure from Nonlawyer, Form 12.900(a). We sign it too. You keep a copy. It takes about a minute.

STEP 02

Choose your forms, then answer the questionnaire

You select which forms you want assembled, then enter your own facts online — income, the existing order, the children, what changed. Plain questions, no legal jargon. Save and come back anytime.

STEP 03

Clerical check, then your packet

Your answers are placed onto the forms. A nonlawyer document preparer checks the packet for clerical errors and returns anything unclear to you to confirm. You get signature-ready PDFs plus filing instructions.

The package

Six forms most Florida parents file with this petition.

These are the forms the Florida Supreme Court's own instructions for Form 12.905(b) identify as required or commonly needed. You decide which ones apply to your case — select them at checkout and the system assembles what you select. Each one links to the court's instruction sheet so you can read it before you choose.

In plain language

Who does what, exactly.

Florida law lets a judge change a child support order when there has been a substantial change in circumstances and the change is in the children's best interests. Making that request means filing a supplemental petition and a set of supporting forms, correctly, in the county where your original order was entered.

You supply every fact. There is no interview and no one typing on your behalf. You enter your information directly into an online questionnaire, in your own words. The system places those answers onto the official forms you selected. Then one person — a Florida nonlawyer document preparer — looks at the assembled packet for clerical problems only.

The clerical check covers

  • Fields left blank that the form requires
  • Misspellings and typos in names, addresses, and dates
  • Dates and figures that don't match between forms
  • Missing signature, notary, or deputy clerk lines
  • Pages out of order or attachments not referenced
  • Whether the form version is the one currently published by the Florida courts

The clerical check does not cover

  • Whether your facts amount to a substantial change in circumstances
  • Whether you should file at all, or where
  • Which forms your particular case requires
  • What to write in any blank, or how to word an answer
  • What your rights or remedies are
  • What a judge is likely to decide

If the preparer finds something clerical, it comes back to you as a question — “the date in paragraph 2 reads 2019 here and 2021 on the affidavit; which is correct?” — and you make the call. We do not change the substance of your answers. If your question is a legal one, we will say so plainly and point you to a Florida attorney rather than guess.

Registration takes a few minutes. You'll sign the nonlawyer disclosure first, then choose your forms and start the questionnaire. Nothing is assembled until both are done.

Questions parents ask

Before you start.

Are you lawyers?

No. JusticeXpress Florida is a nonlawyer document preparation service. Under Rule 10‑2.1(b) of the Rules Regulating The Florida Bar, a nonlawyer may place the factual information you provide in writing into Florida Supreme Court approved forms and may tell you how to file them. A nonlawyer may not give legal advice, tell you what your rights or remedies are, tell you what to put in a blank, or represent you in court. We are also not paralegals as that term is defined by the rule.

Who actually fills in my forms?

You do. Every fact on your forms comes from answers you type into the questionnaire yourself. Our software places those answers onto the correct fields of the forms you selected. No employee interviews you, interprets your situation, or supplies content you didn't write. That's deliberate: it keeps the judgment about your case with you, where Florida law requires it to be.

What does the “review” actually include?

It is a clerical check, not a legal opinion. A Florida nonlawyer document preparer compares the assembled packet against the Florida courts' published instructions for each form and looks for required fields left blank, misspellings in names and addresses, dates or figures that conflict between forms, missing signature and notary lines, and outdated form versions.

If something looks off, it comes back to you as a question and you decide. The preparer does not rewrite your answers, evaluate whether your petition is likely to succeed, or tell you what a blank should say. Those are legal questions for an attorney.

How do I know which forms my case needs?

You decide. We list the forms the Florida Supreme Court's published instructions for Form 12.905(b) identify as required or commonly filed, and we link you to the court's own instruction sheet for each one so you can read it yourself. You select what you want assembled. We cannot advise you on which forms to use — if you're unsure, read the court's instructions or consult a Florida attorney.

When do I sign the nonlawyer disclosure?

Immediately at registration, before any form is assembled. Form 12.900(a), Disclosure from Nonlawyer, is executed electronically and signed by both you and the nonlawyer who will perform the clerical check. You receive a copy to keep and we retain one in your file. Our name, business name, address and telephone number also appear at the bottom of every form we assist with, as the rule requires.

Will this get my child support lowered?

We can't tell you that, and anyone who does is guessing. Only a judge decides. Florida requires a substantial change in circumstances and a finding that the change is in the children's best interests. What we stand behind is the paperwork: complete, clerically checked, on current court-approved forms, delivered ready for your signature.

Do you file it for me?

No. You file your own case, either at the clerk's counter or through the Florida Courts E‑Filing Portal. We include written instructions covering where to file, what the clerk will ask for, which pages need a notary or deputy clerk, and how personal service on the other parent works. Personal service is required for every supplemental petition — you cannot mail it yourself.

Is what I tell you confidential?

Not in the legal sense. Because we are not attorneys, there is no attorney‑client privilege, and the information you enter is not privileged the way it would be with a lawyer. We protect your data as a matter of business practice and privacy law, but we want you to understand the distinction before you decide to use us.

Can I get the forms for free?

Yes, and we'll tell you where: every Florida Supreme Court Approved Family Law Form is published free at flcourts.gov, and your clerk's office will hand you a packet. What $89 buys is the questionnaire that turns plain questions into a completed packet without you re-entering the same information eleven times, and a clerical check before you file. If you'd rather do it yourself from the free forms, that is a completely legitimate choice and we'll point you to them.

Required disclosure

Read this before you buy anything.

JusticeXpress Florida is not a law firm and is not a substitute for the advice of an attorney. The individual who reviews your assembled forms is a nonlawyer — a person who is not a member in good standing of The Florida Bar — and may not give legal advice, may not tell you what your rights or remedies are, may not tell you how to testify in court, and may not represent you in court.

Rule 10‑2.1(b) of the Rules Regulating The Florida Bar defines a paralegal as a person who works under the supervision of a member of The Florida Bar. The nonlawyer who reviews your forms does not meet that definition and does not hold themselves out as a paralegal.

Rule 10‑2.1(b) permits a nonlawyer to place into the blanks on a form only the factual information you provide in writing, and, where the form is one approved by the Supreme Court of Florida, to ask you factual questions to fill in those blanks and to tell you how to file the form. Except for that, a nonlawyer may not tell you what to put in the form and may not complete the form for you.

Our service is narrower than what the rule allows. You enter your own factual information directly into an online questionnaire. Our software places your answers onto the forms you have selected. No person at JusticeXpress Florida supplies, interprets, or edits the substance of your answers. The nonlawyer's role is limited to a clerical check for blank fields, misspellings, inconsistent dates or figures, missing signature and notary lines, and outdated form versions. Anything the preparer flags is returned to you as a question for you to resolve.

Before any form is assembled, you and the nonlawyer will complete and sign Disclosure from Nonlawyer, Florida Family Law Rules of Procedure Form 12.900(a). You will receive a signed copy to retain; we keep a copy in your file, along with copies of every form provided to you, for at least six years.

No outcome is promised or implied. Filing these forms does not guarantee that a court will modify your child support order. Purchase of this package does not create an attorney‑client relationship, and communications with us are not protected by attorney‑client privilege.
