A financial affidavit is the most important document in a divorce that involves money — which is almost every divorce. It’s a sworn statement of your financial life: what you earn, what you spend, what you own, and what you owe. Courts use it to decide alimony, child support, and property division.

Getting it wrong isn’t just inconvenient. It’s a sworn document. Errors can look like fraud. Omissions can cost you in the settlement. And the most common reason people struggle with it has nothing to do with the form itself — it’s gathering the data to fill it out.

What Is a Financial Affidavit?

A financial affidavit (sometimes called a financial declaration, sworn financial statement, or case information statement depending on your state) is a court-required document that lists your complete financial picture. Both parties in a divorce must file one.

It covers four areas:

Income — salary, bonuses, freelance income, rental income, investment returns, government benefits
Monthly expenses — housing, food, transportation, insurance, childcare, personal spending
Assets — bank accounts, retirement accounts, real estate, vehicles, investments, personal property
Liabilities — mortgage, car loans, student loans, credit cards, tax debts, personal loans

The court needs this to make fair decisions. If one spouse earns $150,000 and the other earns $40,000, that changes alimony calculations. If monthly expenses for the children total $3,200, that affects child support. If there’s $400,000 in retirement assets, that’s part of property division.

Every state has its own form. Florida uses a Family Law Financial Affidavit. California uses an Income and Expense Declaration (FL-150) plus a Schedule of Assets and Debts (FL-142). New York uses a Statement of Net Worth. The categories are similar; the format varies.

What Information You Need to Gather

Before you touch the form, collect everything. This is where the real work happens.

Income documentation:

Last 2-3 years of tax returns (federal and state)
Last 3-6 months of pay stubs
1099s for freelance or contract work
K-1 forms if you have business or partnership income
Social Security benefit statements
Rental income records
Investment account statements showing dividends and interest

Bank and credit card statements:

12-24 months of statements for every account (checking, savings, money market)
12-24 months of credit card statements
This is typically 3-8 different accounts across multiple banks

Asset documentation:

Retirement account statements (401k, IRA, pension)
Investment account statements (brokerage, mutual funds)
Real estate — current value and mortgage balance
Vehicle titles and current values (KBB or NADA)
Life insurance policies (especially whole life with cash value)
Business ownership documents and valuations

Debt documentation:

Mortgage statements
Auto loan balances
Student loan balances
Credit card balances (every card)
Personal loans
Tax debts
Medical debt

The Bank Statement Problem

This is where most people get stuck. The financial affidavit asks for your average monthly expenses broken down by category: housing, food, transportation, utilities, clothing, entertainment, personal care, and so on.

You don’t know your average monthly spending on groceries off the top of your head. Nobody does. So you need to go through your bank and credit card statements, categorize every transaction, and calculate monthly averages.

For a typical divorce, that means:

12-24 months of statements
3-5 different accounts (checking, savings, multiple credit cards)
Hundreds to thousands of individual transactions
Each one needs to be categorized

And bank statements come as PDFs. Different banks use different formats. Chase statements look nothing like Bank of America statements. Credit card statements have a different layout than checking account statements. Copying data from PDFs into a spreadsheet produces broken columns and garbled text.

This is the bottleneck. People spend days manually copying and categorizing transactions, or they give up and estimate — which creates problems later (more on that below).

Step by Step: Filling Out Each Section

Section 1: Income

Start with gross income (before taxes). Include everything:

Employment income — use your most recent pay stub for current salary. If income varies (commissions, overtime, bonuses), average the last 12 months.
Self-employment income — net income from your business. Use tax returns for the most accurate number.
Investment income — dividends, interest, capital gains. Use your 1099-DIV and 1099-INT forms.
Rental income — gross rent minus documented expenses.
Other income — Social Security, disability, pension payments, alimony from a previous marriage.

Then list your deductions: federal tax, state tax, Social Security, Medicare, health insurance, retirement contributions, union dues.

The difference is your net income. This number drives alimony and child support calculations.

Section 2: Monthly Expenses

This is the section that requires bank statement analysis. You need actual numbers, not estimates.

Common categories (varies by state form):

Housing — mortgage or rent, property tax, homeowner’s insurance, HOA fees, maintenance
Utilities — electricity, gas, water, sewer, trash, internet, phone
Food — groceries and dining out (many forms separate these)
Transportation — car payment, insurance, gas, maintenance, parking, public transit
Healthcare — insurance premiums (if not deducted from paycheck), co-pays, prescriptions, dental, vision
Childcare — daycare, after-school programs, babysitting
Children’s expenses — clothing, school supplies, activities, tutoring
Insurance — life, disability (if not through employer)
Personal — clothing, grooming, gym, subscriptions
Entertainment — streaming services, hobbies, vacations
Debt payments — minimum payments on credit cards, student loans, personal loans

For each category, calculate your average monthly spending over the past 12 months. One month isn’t representative — you buy winter coats in November, not June. Annual expenses like property tax or car insurance need to be divided by 12.

This is where analyzing your bank statements becomes essential. You need transaction-level data to calculate accurate category totals.

Section 3: Assets

List everything you own, with current values:

Bank accounts — current balances for every account
Retirement accounts — current balances (note: these may be subject to QDRO for division)
Investment accounts — current market value
Real estate — fair market value (Zillow estimate is a starting point; a formal appraisal may be needed)
Vehicles — current value from KBB or NADA
Personal property — jewelry, art, collectibles, electronics (only items of significant value)
Business interests — your ownership stake and estimated value
Life insurance — cash surrender value for whole life policies

For each asset, note whether it’s marital property, separate property, or mixed. Property you owned before the marriage or received as inheritance is generally separate — but this gets complicated fast, and your attorney should advise.

Section 4: Liabilities

List every debt with the current balance, monthly payment, and whose name is on the account:

Mortgage balance and monthly payment
Home equity line of credit
Auto loans
Student loans
Credit card balances (list each card separately)
Personal loans
Medical debt
Tax debt (federal or state)
Any other obligations

Common Mistakes That Get People in Trouble

Underreporting expenses

Estimating low on expenses because you think it makes you look financially responsible. It doesn’t. It makes your numbers not add up — your income minus your reported expenses shows a surplus that doesn’t match your bank balances. The opposing attorney will catch this.

Forgetting irregular expenses

Annual property tax, semi-annual car insurance, quarterly estimated tax payments, holiday spending, back-to-school costs. These are real expenses that need to be amortized monthly. A $6,000 annual property tax bill is $500/month in your affidavit.

Math errors

Columns that don’t add up, expenses that don’t match income and bank balances, transposed digits. In a sworn financial document, math errors look like intentional misrepresentation. Double-check everything. Then check it again.

Omitting accounts

Every bank account, credit card, investment account, and retirement account must be listed. “I forgot about that old savings account” is not a defense if the other side finds it. Pull your credit report to make sure you haven’t missed any open accounts.

Using round numbers everywhere

If every expense on your affidavit ends in zero ($200 for groceries, $150 for gas, $300 for entertainment), it signals that you estimated everything instead of calculating from actual records. Real spending is $217.43 per month, not $200.

How to Handle Multiple Bank Accounts from Different Banks

Most households have accounts at more than one bank. You might have a checking account at Chase, a savings account at Ally, a credit card with Capital One, and another with Discover. Each one has different statement formats.

You need all of them in one place to get a complete picture of spending. A grocery purchase on your Chase debit card and a grocery purchase on your Capital One credit card are both grocery spending — they need to end up in the same category.

Talio handles the multi-bank problem. Import PDF statements from any bank — each gets normalized into the same clean format. Chase, Bank of America, Wells Fargo, credit unions, credit cards — they all become consistent rows in one spreadsheet. From there, you categorize transactions across all accounts at once instead of juggling separate files.

If you’re doing it manually, create one master spreadsheet with columns for Date, Description, Amount, Account, and Category. Copy data from each statement into this single sheet. It’s tedious but necessary — you can’t calculate accurate monthly spending if your data is scattered across separate files.

Tools That Help

The financial affidavit itself is a court form. You fill it out by hand or in a PDF editor. The hard part isn’t the form — it’s generating the numbers that go into it.

For the bank statement analysis portion, Talio extracts transactions from PDF statements, categorizes them, and generates spending summaries by category. That gives you the monthly averages you need for the expense section. The output is a Google Sheet you can share directly with your attorney.

For the form itself, your attorney will typically provide the correct version for your state and review your completed draft. If you’re doing this pro se (without an attorney), your county clerk’s office or court website has the form.

For asset valuation, you may need a real estate appraiser, a business valuator, or a retirement account specialist depending on your situation. These are separate from the bank statement analysis — but the spending data from your bank statements feeds directly into the expense section of the affidavit.

FAQ

Can I fill this out myself?

Yes. Many people complete their own financial affidavit, especially in uncontested divorces. You don’t need a lawyer to fill out the form. You do need accurate financial data — which means going through your bank statements and gathering documentation. If your finances are straightforward (W-2 income, standard bank accounts, no business interests), this is very doable. If your divorce costs are a concern, doing the financial preparation yourself is one of the most effective ways to save money.

What if I don’t have all my statements?

Contact your bank. Most banks provide up to 7 years of statements, either through online banking or by request. There may be a fee for older paper statements ($5-10 per statement is common). Your bank is required to provide them. If your spouse controlled the finances and you don’t have account access, your attorney can subpoena the records.

What happens if I get it wrong?

A financial affidavit is a sworn document. Intentional misrepresentation is perjury. Unintentional errors can be corrected with an amended filing, but they damage your credibility. The opposing attorney may argue that “mistakes” were intentional. This is why using actual transaction data instead of estimates matters — you can point to the source records that support every number.

How far back do I need to go?

Most jurisdictions require 12 months of financial records. Some require 24 months. Contested divorces with suspected hidden assets may require going back further. Your attorney or the court’s instructions will specify the required period.

Do both spouses file a financial affidavit?

Yes. Both parties must complete and file their own financial affidavit. This is how the court gets both sides of the financial picture. Discrepancies between the two affidavits often become points of negotiation or litigation.
