How to Fill Out an FL-150 (Income and Expense Declaration)

The FL-150 is the most important financial document you will file in a California divorce or custody case. It is also one of the easiest to get wrong.

If you are representing yourself, the form can feel overwhelming. It asks for detailed information about your income, expenses, assets, and debts. Every number you enter carries weight. Judges rely on the FL-150 to make decisions about child support, spousal support, and attorney fee awards. Opposing counsel will use it to challenge your credibility.

The good news: filling it out correctly is not complicated once you understand what each section is asking and why it matters. This guide walks you through the form page by page, explains the most common mistakes people make, and shows you how to avoid the financial traps that catch even careful filers off guard.

What the FL-150 Is and When You Need It

The FL-150, officially titled "Income and Expense Declaration," is a Judicial Council form used in virtually every California family law proceeding that involves money. If anyone is requesting child support, spousal support, or attorney fees, you will almost certainly need to file one.

Courts require the FL-150 because they need an accurate snapshot of each party's financial situation. Without it, a judge has no reliable basis for setting support amounts. In most cases, both sides must file their own FL-150, and both must attach recent pay stubs and a completed tax return.

You may need to file an FL-150 at several points during your case: when a request for order (RFO) is filed, at a mandatory settlement conference, at trial, and sometimes in connection with your preliminary declaration of disclosure. If your financial situation changes, you may be required to file an updated one.

Step-by-Step Breakdown: Filling Out the FL-150

Section 1: Employment Information

Start with the basics. List your current employer, your job title, and the address where you work. If you are self-employed, write "self-employed" and provide your business name and address.

This section also asks when you started working at your current job and how many hours you work per week. Be accurate. If your hours vary, estimate the average over the last several months. If you have more than one job, list the primary one here and detail additional employment income later in the income section.

Sections 2 Through 4: Income

This is the heart of the form. You need to report your gross monthly income from all sources. Not annual. Monthly. This is where many people make their first mistake, either by reporting annual figures or by accidentally leaving out income sources.

The form asks about salary and wages, overtime, commissions, bonuses, and tips. It also asks about income from rental properties, dividends, interest, retirement or pension payments, social security, disability, unemployment, and any other source of money coming in.

If your income fluctuates, the court generally expects you to average it. For example, if you are a commissioned salesperson whose income varies significantly month to month, add up the last twelve months of income and divide by twelve. Attach a brief explanation if the number does not reflect a typical month.

You must also list your payroll deductions: federal and state taxes, FICA, health insurance premiums, mandatory retirement contributions, and union dues. These deductions reduce your gross income to arrive at your net disposable income, which is a key number in support calculations.

Sections 9 Through 11: Monthly Expenses

Here you report your actual monthly expenses. Not what you wish you spent. Not what you plan to spend once you have two households. What you are actually spending right now.

This includes rent or mortgage, property taxes and insurance, food, utilities, phone, laundry, clothing, education, entertainment, auto expenses, insurance premiums, and health care costs not covered by insurance.

Do not inflate your expenses. This is one of the most tempting mistakes and one of the most damaging. Judges and attorneys review FL-150 expense declarations constantly. If your reported expenses exceed your reported income by a wide margin and you have no explanation for how you are making ends meet, the court will notice. The question becomes: are you hiding income, or are you inflating expenses? Neither conclusion helps you.

Section 12: Attorney Fees

If you have an attorney, report the total amount you have paid and the amount you still owe. If you are representing yourself, you can note any fees you have paid for legal coaching, document preparation services, or mediation.

This section matters because the court considers each party's access to legal representation when deciding whether to order one side to contribute to the other's attorney fees.

Sections 13 Through 17: Assets and Debts

The final sections ask about your property, savings accounts, investment accounts, vehicles, and debts. You do not need to provide exact balances to the penny, but your estimates should be reasonable and made in good faith.

If you own real property, list the fair market value and the outstanding mortgage balance. For bank accounts, provide the approximate current balance. For debts, include credit cards, student loans, auto loans, and any money you owe to family or friends.

Be thorough. Leaving out an asset does not make it invisible. Discovery, subpoenas, and forensic accountants can uncover anything you fail to disclose, and the consequences of omitting assets are far worse than simply listing them.

Attaching Pay Stubs and Tax Returns

The FL-150 does not stand alone. California law requires you to attach your two most recent pay stubs and your most recently filed tax return, including all schedules and W-2s. If you are self-employed, attach your most recent Schedule C, profit and loss statement, or 1099 forms.

Missing attachments are one of the fastest ways to have your FL-150 rejected or your credibility questioned. If you do not have your pay stubs, contact your employer's payroll department. If you have not filed your most recent tax return, that itself may become an issue in your case.

Common Mistakes That Hurt Your Case

Reporting Annual Income Instead of Monthly

The form asks for monthly figures. It says so clearly at the top. But people still enter their annual salary in the monthly income box. If you earn $72,000 per year, your monthly income is $6,000. Entering $72,000 as your monthly income will either make you look careless or dishonest.

Forgetting Irregular Income

Bonuses, commissions, rental income, side work, cash payments, stock vesting, and cryptocurrency gains all count as income. If it puts money in your pocket, it goes on the FL-150. Omitting these sources can be treated as a material misrepresentation.

Inflating Expenses

Listing $2,000 per month in food expenses for a single person with no explanation will raise questions. Judges see hundreds of these forms. They know what reasonable expenses look like. Stick to what you actually spend and be prepared to back it up with bank or credit card statements.

Leaving Sections Blank

A blank section is ambiguous. The court does not know whether you forgot, did not understand the question, or are deliberately withholding information. If a section does not apply, write "N/A" or "0." Every field should have an entry.

Inconsistencies Between the FL-150 and Other Documents

Your FL-150 will be compared to your tax returns, pay stubs, bank statements, and any other financial disclosures you have made. If the income on your FL-150 does not match your pay stubs, you have a credibility problem. Review everything for consistency before you file.

Financial Traps to Watch For

Understating Income to Reduce Support Obligations

This happens more than you might expect. A wage earner voluntarily reduces their hours, or a self-employed person suddenly reports dramatically lower income right before filing. Courts are alert to this. Under California law, a judge can impute income to a party who is found to be deliberately underemployed or underreporting income. That means the court can calculate support based on what you could be earning, not what you claim to be earning.

Hiding Assets or Accounts

Transferring money to a friend, opening accounts in a family member's name, or simply not listing a brokerage account does not make it disappear. The discovery process in family law cases is broad. Bank records, tax transcripts, and forensic analysis can reveal hidden accounts. If you are caught, the consequences can include sanctions, adverse inferences, and a disproportionate division of assets in the other party's favor.

Failing to Update the FL-150 When Circumstances Change

If you filed an FL-150 six months ago and your income has changed, your old form is stale. Filing an outdated FL-150 for a new hearing is misleading, even if the numbers were accurate when you first signed it. Always file a current form that reflects your situation as of the date you sign it.

Overstating Expenses to Argue for Higher Support

On the other side of the coin, the party requesting support sometimes inflates expenses to create the appearance of greater need. But if your total claimed expenses are $12,000 per month and you have been surviving on $4,500 per month for the past year with no debt accumulation, the math does not add up. The court will notice.

What Most People Don't Realize

The FL-150 is signed under penalty of perjury. This is not a formality. Every number you write is a sworn statement. Intentional misrepresentations can result in sanctions, contempt findings, and damage to your credibility that extends far beyond a single hearing.

Many people also do not realize that the FL-150 is one of the first documents opposing counsel will scrutinize. If you are involved in a contested case, expect the other side to compare your FL-150 against every financial document in the file. Small inconsistencies become big arguments.

Finally, understand that the FL-150 is not just a form; it is evidence. A well-prepared FL-150, consistent with your supporting documents and clearly filled out, signals to the court that you are organized, transparent, and credible. A sloppy or inconsistent one does the opposite.

What This Means in Practice

Suppose you are the higher-earning spouse and your ex is requesting spousal support. The court will look at both FL-150s side by side: your income, your expenses, your assets, your debts. If your FL-150 is vague, incomplete, or inconsistent with your pay stubs, the judge may draw unfavorable inferences. If it is thorough and well-supported, it strengthens your position.

Now suppose you are the lower-earning spouse requesting support. Your FL-150 needs to clearly and honestly show your expenses and demonstrate the gap between what you earn and what you need. Inflated expenses will not help. Honest, documented expenses will.

In either scenario, the FL-150 is doing the work of presenting your financial picture to the court. Treat it like the sworn testimony that it is.

Practical Takeaways

Gather your documents first. Before you touch the form, collect your two most recent pay stubs, your last filed tax return with all schedules, three months of bank statements, and a list of your monthly bills. Having everything in front of you prevents guesswork.

Report monthly, not annual. Double-check that every income and expense figure is a monthly number. If you need to convert, divide your annual figure by twelve.

Be honest and thorough. Report all income sources, list all assets and debts, and fill in every section. Use "N/A" or "0" where a section does not apply.

Cross-check your numbers. Compare your FL-150 entries against your pay stubs and tax returns. If there is a discrepancy, either correct the FL-150 or attach a written explanation.

Do not inflate or deflate. Report your actual expenses and your actual income. Courts are experienced at spotting unrealistic numbers, and the credibility cost is not worth it.

Attach everything. Missing pay stubs or a missing tax return can delay your case or invite scrutiny. Include all required attachments when you file.

Update when things change. If your income or expenses shift significantly after filing, prepare an updated FL-150 for your next court appearance.

The FL-150 is not the hardest part of a divorce, but it is one of the most consequential. Every financial decision the court makes in your case will flow, at least in part, from the information on this form.

Take the time to do it right. Gather your documents, be honest, check your math, and attach everything the court requires. If you approach it with care, the FL-150 becomes a straightforward part of the process rather than a source of stress.
