Frequently Asked Questions About Form Form 12.902(l)

You must complete this form if you or the other party is requesting to establish or change a child support order in your case. It is filled out by either the Petitioner or the Respondent after financial affidavits have been exchanged.

You must file the original form with the clerk of the circuit court in the county where your case is located. A copy must also be served on the other party in your case, and you should keep a copy for your records.

Compliance Form 12.902(l)
Validation Checks by Instafill.ai

1
Verifies Gross Income Summation
This check ensures that the value in 'TOTAL PRESENT MONTHLY GROSS INCOME' (Line 17) is the correct sum of all income sources listed in Lines 1 through 16. This is critical for establishing the foundational income figure used in all subsequent child support calculations. If the sum is incorrect, the form submission will be blocked, and the user will be prompted to review and correct the individual income entries.
2
Verifies Total Deductions Summation
This validation confirms that the 'TOTAL DEDUCTIONS' field (Line 29) accurately reflects the sum of all individual deduction lines (18 through 28). Correctly calculating total deductions is essential for determining the final net income. An incorrect sum will trigger an error, requiring the user to verify the amounts entered for taxes, insurance, and other court-ordered payments.
3
Verifies Net Income Calculation
This check validates that the 'PRESENT MONTHLY NET INCOME' (Line 30) is correctly calculated by subtracting 'TOTAL DEDUCTIONS' (Line 29) from 'TOTAL PRESENT MONTHLY GROSS INCOME' (Line 17). This final figure is the basis for the child support determination, making its accuracy paramount. A calculation mismatch will prevent submission and force a correction of the underlying income or deduction figures.
4
Ensures Filer Identification is Complete
This check confirms that the 'full legal name' field is filled and that exactly one of the checkboxes for 'Petitioner' or 'Respondent' is selected. This information is fundamental for identifying who is submitting the affidavit and their role in the case. Failure to provide this information makes the document legally insufficient and will block submission until completed.
5
Validates Unemployment Status Consistency
If the 'Check here if unemployed' checkbox is selected, this validation verifies that the 'Salary or wages' field (Line 1) is zero. This check prevents logical contradictions where a user claims to be unemployed while also listing a salary. An inconsistency would prompt the user to either uncheck the box or correct the salary field to ensure the affidavit is factually consistent.
6
Requires Court Identification for Specific Deductions
This check ensures that if a monetary value greater than zero is entered for 'Court-ordered support for other children' (Line 26) or 'Court-ordered alimony for prior marriage' (Line 28), the corresponding 'Court' text field is also filled out. This provides necessary context and verifiability for these legal deductions. If the court name is missing, the user will be prompted to provide it before proceeding.
7
Validates Certificate of Service Section
This validation confirms that at least one service method checkbox (e-mailed, mailed, etc.) is checked and that the 'Service Date' field is filled with a valid date. This is a legal requirement to certify that the document was properly served on the other party according to court rules. An incomplete certification section will prevent submission and prompt the user to complete it.
8
Ensures Service Date is Valid
This check validates that the 'Service Date' is entered in a proper format (e.g., MM/DD/YYYY) and is not a date in the future. A valid service date is essential for legal timelines and proving compliance with court rules. An invalid format or a future date will result in an error message requiring correction before the form can be filed.
9
Validates Format of All Monetary Fields
This check ensures that all income and deduction fields (e.g., Lines 1-16, 18-28) contain only valid, non-negative numeric or currency values. This prevents data entry errors, such as entering text like 'None' or negative numbers, which would break calculations. Invalid entries will be flagged for correction, ensuring the data integrity required for legal financial calculations.
10
Validates Number of Dependents Format
This check verifies that the 'Number of dependents claimed' field (Line 19b) contains a non-negative integer (e.g., 0, 1, 2). Claiming a fractional or negative number of dependents is illogical and indicates a data entry error that could affect tax calculations. The system will reject invalid formats and require the user to enter a whole number.
11
Validates Email Address Structure
This check verifies that all email address fields ('Filer Email Address', 'Other Party Email Addresses', etc.) follow the standard '[email protected]' format. Proper email formatting is critical for successful e-filing and e-service as required by Florida court rules. An invalid email format will trigger an error, preventing potential service failures and ensuring compliance.
12
Ensures Case Header is Complete
This validation ensures that the 'Case No.', 'County', and 'Circuit Number' fields at the top of the form are all filled out. This information is essential for the clerk of court to correctly file the document under the proper case docket. Missing header information would cause the filing to be rejected by the court, so submission is blocked until these fields are complete.
13
Requires Jurisdiction for State/Local Taxes
This check ensures that if a value greater than zero is entered for 'State Income Tax' (Line 19d) or 'Local Income Tax' (Line 19e), the corresponding 'State' or 'Locality' text field is filled. This provides necessary context for the tax deduction being claimed and is required for verification. Failure to specify the jurisdiction will prompt the user for the required information before submission.
14
Flags if Deductions Exceed Gross Income
This validation checks if 'TOTAL DEDUCTIONS' (Line 29) is greater than 'TOTAL PRESENT MONTHLY GROSS INCOME' (Line 17). While a negative net income is possible, it is highly unusual and often indicates a significant data entry error. The system should display a prominent warning asking the user to confirm the amounts are correct before allowing submission.

Common Mistakes in Completing Form 12.902(l)

Incorrectly Calculating Monthly Income

The form requires all income to be reported as a monthly amount, but people are often paid weekly or bi-weekly. A common error is to multiply weekly pay by 4, which under-reports annual income. The correct method is to convert pay to an annual amount (e.g., bi-weekly pay x 26) and then divide by 12. This miscalculation can significantly skew child support obligations and lead to challenges in court. AI-powered tools like Instafill.ai can automatically perform these conversions correctly, ensuring accuracy.

Confusing Gross Income with Net (Take-Home) Pay

Filers often enter their net pay in the 'Salary or wages' field instead of their gross (pre-tax) earnings. The form is designed to calculate net income by starting with gross income and then subtracting specific deductions in a separate section. Entering net pay upfront results in double-counting deductions and incorrectly lowering the final net income figure, which can lead to an inaccurate and challengeable child support calculation. Always refer to the gross pay amount on your pay stub for the initial income fields.

Omitting Irregular or Non-W2 Income

Income from sources like bonuses, commissions, overtime, tips, or self-employment is often forgotten or intentionally omitted because it's not part of a regular salary. The form explicitly requires these to be included in lines 2 and 3. Failing to report all income sources can be considered a misrepresentation to the court and may lead to sanctions or future modifications if discovered. To avoid this, review pay stubs and tax returns from the past year to calculate an average monthly amount for this type of income.

Incorrectly Reporting Health Insurance Deductions

The form has two separate lines for health insurance premiums: one for the parent's own coverage (Line 24) and one for the portion paid for the minor child(ren) (Line 25). A frequent mistake is to lump the entire premium into one line or put the child's portion on the wrong line. This error leads to an incorrect calculation of the parent's net income and misallocation of health insurance costs in the final child support order. Carefully check your pay stub or insurance bill to separate these costs accurately.

Failing to Complete the Case Header Information

The top of the form requires the Judicial Circuit, County, Case Number, and Division. Filers, especially those representing themselves, often leave these fields blank or fill them in incorrectly. This can cause the clerk of court to reject the filing or misroute the document, leading to significant delays in the case. This information is found on all previous documents filed in your case and must be copied exactly.

Forgetting to Address Unemployment Status Correctly

If a person is unemployed, they might simply leave the income section blank. However, the form requires them to explicitly check the box indicating they are unemployed and, crucially, attach a separate sheet explaining their efforts to find employment. Failing to provide this explanation can be viewed negatively by the court, suggesting a lack of good faith in seeking work to support their child.

Improperly Handling Confidential Address Information

The instructions provide a specific procedure (filing Form 12.980(h)) for victims of domestic violence to keep their address confidential. A critical and dangerous mistake is to ignore this and write the confidential address directly on the form, making it a public record. This compromises the filer's safety and can have severe personal consequences. It is vital to follow the special instructions and file the separate request for confidentiality instead of listing the address on this affidavit.

Missing or Incorrect Certificate of Service

The Certificate of Service at the end of the form is a legal declaration that you have sent a copy to the other party. Common mistakes include forgetting to fill it out, entering the wrong date, or failing to check the box indicating how it was sent (e.g., e-mail, mail). An incomplete Certificate of Service can invalidate the filing and lead to procedural challenges from the other party, delaying the legal process.

Failing to Sign the Affidavit Under Oath

The signature line is preceded by the phrase 'Under penalties of perjury,' making the signature a sworn statement. Forgetting to sign the document renders it invalid and it will be rejected by the court, having no legal effect. Since many court forms are provided as non-fillable PDFs, it can be easy to print and forget to sign. Tools like Instafill.ai can convert these into fillable forms and use validation checks to flag unsigned signature fields before submission.

Misstating Tax Deductions and Filing Status

The form requires filers to list their tax filing status, number of dependents, and the resulting monthly tax deductions. People often guess these amounts or use the amount withheld on their last paycheck, which may not accurately reflect their actual annual tax liability. Using incorrect tax information directly impacts the calculation of net income and can lead to an inaccurate support order. It is best to consult recent tax returns or a tax professional to determine the most accurate figures for these fields.
