A financial declaration in family law is a sworn court document in which you disclose your income, expenses, assets, and debts so a judge can decide questions about child support, spousal maintenance, or how to divide marital property. Nearly every family law case involving money requires one from both sides, and the accuracy of what you file matters: federal perjury law sets a maximum penalty of five years in prison for anyone who knowingly lies under oath on one of these forms.1Office of the Law Revision Counsel. 18 USC 1621 – Perjury Generally
When a Financial Declaration Is Required
Courts call for a financial declaration any time a judge needs your numbers to rule on a pending issue. The common triggers are divorce or legal separation, a request for child support, a petition for spousal maintenance, and disputes over dividing marital property. Post-judgment, the same requirement applies: if you or your ex wants to modify child support or maintenance because someone’s income changed or a child’s needs shifted, the court will want fresh numbers from both parties.
Even temporary orders at the start of a case usually require a declaration. Judges set interim support and possession of property based on these early filings, so getting the form right from the outset matters more than most people realize. A sloppy first declaration can lock in temporary support at an amount that is hard to walk back later.
What Goes on the Form
Every state has its own standardized financial declaration form, usually available on the state court’s website or at the local clerk’s office. Whatever the state, the form will ask about four categories.
Income
Report both gross income (before taxes) and net pay (after mandatory deductions like taxes, Social Security, and health insurance). Income is more than your paycheck: wages, salary, bonuses, commissions, overtime, dividends, rental income, retirement distributions, and government benefits all belong on the form. Use actual figures, not rounded estimates. Courts and opposing attorneys cross-check your declaration against your pay stubs and tax returns, and a figure that doesn’t match invites scrutiny of the whole document.
Expenses
The form asks for a detailed monthly breakdown: housing, utilities, food, transportation, insurance premiums, childcare, medical costs, and similar recurring obligations. Each figure should be a realistic monthly average rather than an unusually expensive month or an unusually lean one. Judges spot inflated expense claims quickly, and overstating costs damages your credibility on everything else in the declaration.
Assets
List the current fair market value of what you own: real estate, vehicles, bank accounts, retirement accounts, investment portfolios, life insurance with cash value, and personal property of significant value such as jewelry or collections. For real estate, fair market value is what the property would sell for today, not what you paid or what you owe. Equity (market value minus loan balance) is what matters for division, but both figures go on the form.
Debts
Every liability belongs on the form: mortgage balances, car loans, credit card balances, student loans, medical debt, personal loans, and tax obligations. For each, include the creditor name, total balance, and monthly payment. Leaving off a credit card you would prefer the judge not see is one of the fastest ways to lose credibility in a family law case.
Extra Requirements for Self-Employed Filers
If you own a business, work as an independent contractor, or have partnership income, expect to produce significantly more documentation than a salaried employee. Courts know self-employment income is easier to manipulate, and the scrutiny rises accordingly.
Beyond personal tax returns, you will generally need to provide business tax returns, year-to-date profit and loss statements, balance sheets, and business bank statements. Partners in a business should expect to produce their Schedule K-1 forms, which report each partner’s share of the partnership’s income, deductions, and credits.2Internal Revenue Service. Partners Instructions for Schedule K-1 Form 1065 Sole proprietors file a Schedule C with their personal return that serves a similar purpose.
Courts also pay close attention to discretionary business expenses when a self-employed party’s reported income looks low. Personal costs run through a business, such as a vehicle used partly for personal errands, meals, or travel, can be added back to income for support calculations. If your business pays for your car, phone, and meals, a judge may treat some of those as income even though they do not appear on a W-2.
When the Court Assigns Earning Capacity
If the court believes you are voluntarily unemployed or underemployed to reduce a support obligation, it can impute income to you, meaning the judge calculates support based on what you could earn rather than what you report earning. Showing very low income when your education, work history, and health suggest you could earn more invites exactly that finding.
Federal child support guidelines require any imputation to take into account the parent’s specific circumstances, including work history, education, professional skills, health, and local job availability. Courts cannot simply plug in a standard amount like the minimum wage without considering the facts of the individual case.3Administration for Children and Families. Final Rule – Flexibility, Efficiency, and Modernization in Child Support Enforcement Programs
Legitimate reasons for reduced earnings exist, and courts recognize them. Documented medical conditions, caregiving arrangements agreed on during the marriage, and genuine layoffs in a depressed job market can all explain lower income without triggering imputation. The key is documentation. Bring proof.
Documents You Need to Attach
Your numbers are only as credible as the paperwork behind them. Courts generally require the following, though the exact list and time periods vary by jurisdiction:
- Federal and state tax returns for the last two to three years
- Recent pay stubs covering the last two to six months
- Bank statements from all checking, savings, and money market accounts, typically for the last three to six months
- The most recent statements for brokerage accounts, 401(k) plans, IRAs, pensions, and similar holdings
- Mortgage statements, property tax bills, and any recent real estate appraisals
- Current statements for credit cards, student loans, car loans, and other liabilities showing balances and monthly payments
These attachments let the court and opposing counsel audit your declaration line by line. Mismatches between reported figures and supporting documents are the most common way concealment gets caught.
Redacting Sensitive Information Before Filing
Financial declarations and their attachments contain some of the most sensitive data you will ever place in a court file. Federal courts require specific redactions under the Federal Rules of Civil Procedure, and most state courts follow similar rules.4Legal Information Institute. Federal Rules of Civil Procedure Rule 5.2 – Privacy Protection for Filings Made with the Court Standard redactions are:
- Social Security numbers: last four digits only
- Financial account numbers: last four digits only
- Minor children’s names: initials only
- Birth dates: year only
The duty to redact falls on you and your attorney, not the clerk’s office. If you file an unredacted document without requesting it be sealed, you waive privacy protection for that information.4Legal Information Institute. Federal Rules of Civil Procedure Rule 5.2 – Privacy Protection for Filings Made with the Court You can file a redacted version for the public record and an unredacted copy under seal for the judge, but you have to request that arrangement; it does not happen automatically.
Signing: Declaration or Notarized Affidavit
Not every financial declaration requires a notary. The distinction depends on whether your jurisdiction calls the document a “declaration” or an “affidavit.”
Under federal law, a written statement signed under penalty of perjury has the same legal weight as a notarized affidavit. The signer includes language such as “I declare under penalty of perjury that the foregoing is true and correct,” dates the document, and signs it.5Office of the Law Revision Counsel. 28 USC 1746 – Unsworn Declarations Under Penalty of Perjury Many states follow this approach, meaning you can sign at home without finding a notary. Other states use a “financial affidavit” that does require notarization, where a notary verifies your identity, watches you sign, and applies a seal.
Either format carries the same legal effect. You are swearing the contents are accurate, and knowingly providing false information is perjury. Under federal law, perjury carries a potential fine and up to five years in prison.1Office of the Law Revision Counsel. 18 USC 1621 – Perjury Generally State perjury statutes vary but all treat it as a serious criminal offense. Check your local court’s form; it will tell you which signing method applies.
Filing, Serving, and the Response Deadline
Once signed, the declaration and all supporting documents go to the clerk of the court where your case is pending. Most courts now accept electronic filing through an online portal, though some still allow or require physical delivery or certified mail. Filing fees vary by jurisdiction and the type of motion involved.
Filing is only half the obligation. You must serve a complete copy of everything you filed on the opposing party or their attorney, through personal delivery, mail, or electronic service if the court permits it. After serving, you file a proof of service confirming the other side received the documents.
The opposing party then has a set window to file their own declaration in response. Deadlines vary by jurisdiction but commonly fall between 20 and 45 days from service. Missing it has real consequences. The court can impose monetary sanctions, strike pleadings, or simply proceed using only the complying party’s financial data to set support and divide property. When one side does not show up with their numbers, the judge works with whatever is available.
Your Duty to Update
Filing a financial declaration is not a one-time event. If your circumstances change materially while the case is pending, you have a legal obligation to supplement or correct your earlier disclosure. This duty applies broadly under discovery rules: when you learn that information you previously disclosed is incomplete or incorrect, you must update it.6U.S. District Court for the Northern District of Illinois. Federal Rules of Civil Procedure Rule 26 – General Provisions Regarding Discovery
Common triggers include a job change, a raise or pay cut, an inheritance, a property sale, significant new debt, or a change in dependents. Sitting on changed information is functionally the same as lying on the original form, and courts treat it that way.
Post-judgment, the duty continues in a different form. If you want to modify a support order because your circumstances have changed, you file a new financial declaration reflecting your current situation. The same is true when the other party files for modification; the court will require updated financials from both sides.
Consequences of Inaccurate or Incomplete Filings
Courts have a wide range of tools to punish parties who file misleading declarations, and judges in family law cases use them because the system depends on both sides being honest.
The most dramatic remedy is awarding a hidden asset entirely to the other spouse. If you fail to disclose a bank account, an investment, or other property and it comes to light later, many courts will give the full value of that asset to the other party rather than splitting it. This can happen even after the case is final; fraud in financial disclosures is one of the most reliable grounds for reopening a divorce judgment.
Short of that, courts routinely order the non-complying party to pay the other side’s attorney fees incurred in uncovering hidden information or compelling disclosure. A motion to compel discovery that should have been unnecessary becomes the non-complying party’s expense. Ignoring a court order to produce financial documents can lead to a contempt finding, which carries its own fines and potential jail time separate from any perjury charge.
At the extreme end, knowingly lying on a sworn financial declaration is perjury, which federal law punishes with fines and up to five years in prison.1Office of the Law Revision Counsel. 18 USC 1621 – Perjury Generally Criminal prosecution for perjury in family law cases is uncommon but does happen, particularly in cases involving large assets or repeated, deliberate concealment. The more frequent outcome is that the judge who catches you lying loses trust in your testimony on everything else. In a proceeding that often turns on credibility, that is a cost most people cannot afford.
