Florida financial affidavit: short form 12.902(b) or long form 12.902(c)

The Family Law Financial Affidavit is the form adopted by the Florida Supreme Court on which a party lists monthly income, deductions, expenses, assets, liabilities and contingent items. It comes in two versions, and the version depends on that party’s own gross income, not the household’s.

Section I covers income line by line, from wages and business income to Social Security, alimony received, interest, rent and royalties. Section II lists average monthly expenses, and Section III lists assets and liabilities, with a column for items you claim are nonmarital (Florida Supreme Court Family Law Form 12.902(b), Short Form, with instructions). On the form, nonmarital means an item belongs to one spouse only and should not be divided. The long form adds digital wallets, virtual currency and NFTs to the asset list (Florida Supreme Court Family Law Form 12.902(c), Long Form, with instructions).

The financial affidavit rarely travels alone in Florida. Mandatory disclosure is the exchange of financial documents that Rule 12.285 requires in most family cases. It covers the papers behind the figures on the affidavit, such as tax returns and account statements (Florida Family Law Rules of Procedure, Rule 12.285 Mandatory Disclosure (October 1, 2026)).

Each party completes and signs their own affidavit; a lawyer or a nonlawyer helper may prepare it, and a nonlawyer must fill in the assistance block at the end of the form (Florida Supreme Court Family Law Form 12.902(b), Short Form, with instructions). The forms are published by the Florida courts. The party serves a copy on the other side and files it with the clerk of the circuit court where the petition was filed.

1. Go to the Family Law Forms page of flcourts.gov and open the financial affidavit forms under Form 12.902.
2. Pick Form 12.902(b) or Form 12.902(c) from your individual gross annual income, and check the revision date printed on the form.
3. Read the instructions that come with the form before you fill it in; they hold the conversion method and the deadline.
4. Gather the Rule 12.285 documents listed below, so the figures match what you serve.
5. Sign, serve the other party, file with the clerk, and keep a copy for your records.

• Using the short form because household income is low, when your own gross income is $50,000 or more (Florida Family Law Rules of Procedure, Rule 12.285 Mandatory Disclosure (October 1, 2026)).
• Typing account numbers in full instead of only the last four digits the form asks for (Florida Supreme Court Family Law Form 12.902(b), Short Form, with instructions).
• Leaving a proposed or future expense unmarked instead of writing “estimate” next to it (Florida Supreme Court Family Law Form 12.902(b), Short Form, with instructions).
• Forgetting the Child Support Guidelines Worksheet, Form 12.902(e), when child support is at issue.
• Serving the affidavit without the supporting documents the disclosure rule calls for.

The choice turns on one number. The rule sets the line at $50,000 of gross annual income for the party filling in the form (Florida Family Law Rules of Procedure, Rule 12.285 Mandatory Disclosure (October 1, 2026)). A party under the line can still be asked to complete the long form through standard interrogatories, or by the court on its own motion (Florida Family Law Rules of Procedure, Rule 12.285 Mandatory Disclosure (October 1, 2026)).

In an initial or supplemental case, the affidavit and the other disclosure documents must be served within 45 days of service of the initial pleading on the respondent (Florida Family Law Rules of Procedure, Rule 12.285 Mandatory Disclosure (October 1, 2026)). The form instructions repeat that 45-day window for a party who did not serve the affidavit with the initial papers (Florida Supreme Court Family Law Form 12.902(c), Long Form, with instructions).

Temporary relief hearings run on a shorter clock. A party seeking temporary financial relief serves the documents at least ten days before the hearing, and the responding party at least five days before (Florida Family Law Rules of Procedure, Rule 12.285 Mandatory Disclosure (October 1, 2026)). The parties can agree to extend the time, or a party can ask the court to before the due date (Florida Family Law Rules of Procedure, Rule 12.285 Mandatory Disclosure (October 1, 2026)).

For a permanent request such as child support, alimony or equitable distribution, the rule lists what each party must serve alongside the affidavit (Florida Family Law Rules of Procedure, Rule 12.285 Mandatory Disclosure (October 1, 2026)). These papers are exchanged, not filed: apart from the affidavit and the child support worksheet, nothing produced under the rule goes into the court file without a court order (Florida Family Law Rules of Procedure, Rule 12.285 Mandatory Disclosure (October 1, 2026)).

• Federal and state personal income tax returns, gift tax returns and foreign returns for the past 3 years, with all W-2, 1099 and K-1 forms and schedules (Florida Family Law Rules of Procedure, Rule 12.285 Mandatory Disclosure (October 1, 2026)).
• Pay stubs or other proof of earned income for the 6 months before compliance (Florida Family Law Rules of Procedure, Rule 12.285 Mandatory Disclosure (October 1, 2026)).
• Loan applications, financial statements and credit reports prepared or used within the last 24 months (Florida Family Law Rules of Procedure, Rule 12.285 Mandatory Disclosure (October 1, 2026)).
• Periodic statements for the last 12 months for all checking, savings and other accounts, closed ones included (Florida Family Law Rules of Procedure, Rule 12.285 Mandatory Disclosure (October 1, 2026)).
• Canceled checks and check registers for any account with check-writing privileges (Florida Family Law Rules of Procedure, Rule 12.285 Mandatory Disclosure (October 1, 2026)).
• A statement of the amount and source of all income in the past 6 months that the pay stubs do not show (Florida Family Law Rules of Procedure, Rule 12.285 Mandatory Disclosure (October 1, 2026)).
• Documents that support a claim that an asset or debt is nonmarital, from its acquisition or from the marriage (Florida Family Law Rules of Procedure, Rule 12.285 Mandatory Disclosure (October 1, 2026)).
• Brokerage statements for the last 12 months, and retirement plan statements for the past 12 months with the summary plan description (Florida Family Law Rules of Procedure, Rule 12.285 Mandatory Disclosure (October 1, 2026)).
• Virtual currency statements for the past 12 months and a list of current holdings (Florida Family Law Rules of Procedure, Rule 12.285 Mandatory Disclosure (October 1, 2026)).
• Life insurance declarations pages and health and dental insurance cards; corporate, partnership and trust returns for the last 3 tax years if you hold an interest (Florida Family Law Rules of Procedure, Rule 12.285 Mandatory Disclosure (October 1, 2026)).
• Credit card and loan records for the last 24 months, deeds held in the last 3 years, leases and notes owed to you, premarital agreements and existing support orders (Florida Family Law Rules of Procedure, Rule 12.285 Mandatory Disclosure (October 1, 2026)).

Serving the documents is not the last step. Every party subject to mandatory disclosure must file a Certificate of Compliance, Form 12.932, with the court (Florida Family Law Rules of Procedure, Rule 12.285 Mandatory Disclosure (October 1, 2026)). It lists what you served on the other side.

The certificate is filed, but the documents it lists are not. Keep a dated copy of each item you served, so you can prove what went out and when.

Section I is where clients stall, because each line needs its own proof. Business and rental income are reported as gross receipts minus ordinary and necessary expenses, with a sheet itemizing them (Florida Supreme Court Family Law Form 12.902(c), Long Form, with instructions).

1. Wages and salary: recent pay stubs and last year’s W-2 form.
2. Bonuses, commissions, overtime and tips: the year-end pay stub or a statement from the employer.
3. Business income: Schedule C or K-1 forms, with your itemized sheet of receipts and expenses.
4. Disability, Social Security and reemployment assistance: the award letter or payment history from the paying agency.
5. Pensions, annuities, interest and dividends: plan statements, Form 1099-R, Form 1099-INT or Form 1099-DIV and brokerage statements.
6. Rental income: leases and Schedule E, with the itemized sheet for each property.

Every figure on the form is monthly. The instructions convert biweekly pay by multiplying by 26 and dividing by 12, and semimonthly pay by multiplying by 2 (Florida Supreme Court Family Law Form 12.902(b), Short Form, with instructions). Hourly pay is multiplied by weekly hours, then by 52, then divided by 12 (Florida Supreme Court Family Law Form 12.902(b), Short Form, with instructions).

The current short form ends with a declaration under penalties of perjury that the facts are true, followed by the party’s signature (Florida Supreme Court Family Law Form 12.902(b), Short Form, with instructions). Follow the signature section printed on the version you download.

Keep the affidavit current. The rule creates a continuing duty to supplement documents and affidavits whenever a material change in finances occurs (Florida Family Law Rules of Procedure, Rule 12.285 Mandatory Disclosure (October 1, 2026)).

• Florida Family Law Rules of Procedure, Rule 12.285 Mandatory Disclosure (October 1, 2026): Sets the $50,000 line between Form 12.902(b) and Form 12.902(c), the exemptions and joint waiver, the 45-day and temporary-hearing deadlines, the list of disclosure documents with their periods (canceled checks and registers, the 6-month income statement, nonmarital-claim documents), the duty to supplement and the Certificate of Compliance, Form 12.932.
• Florida Supreme Court Family Law Form 12.902(b), Short Form, with instructions: Gives the monthly conversion method, the nonmarital column, the last-four-digits rule, the “estimate” marking and the declaration under penalties of perjury.
• Florida Supreme Court Family Law Form 12.902(c), Long Form, with instructions: Lists digital wallets, virtual currency and NFTs as assets, requires itemized sheets for business and rental income, and repeats the 45-day service window.
