The AI checks your answers before you download

14 checks built for this form, so a wrong date or a missing answer is caught before anyone else sees it.

Ensures Net Income Does Not Exceed Gross Income

This check validates that for each party (Petitioner, Respondent, Other), the 'Net monthly income' entered in section 2a is less than or equal to the 'Gross monthly income'. This is a logical check to prevent data entry errors and ensure financial calculations are based on valid figures. If net income is greater than gross income, the submission will be flagged for correction as this is financially impossible.

Validates Time-Share Percentage Sum

This validation ensures that the sum of the 'Approximate percentage of time spent with' each party in section 3b equals 100%. This is critical for the child support calculation formula, which relies on an accurate and complete allocation of time. A failure in this check indicates an incomplete or incorrect distribution of parenting time, which would lead to an inaccurate support order.

Child Count Consistency Between Sections

This check cross-references the 'Number of children' specified in section 3a with the number of individual child entries in the table in section 6a. The counts must match to ensure that support is being ordered for all children subject to the order. A mismatch would result in an incomplete or incorrect court order, requiring manual review and correction.

Conditional Earning Capacity Amount

This validation ensures that if a checkbox is marked in section 2b indicating a party has a certain 'earning capacity', the corresponding currency field must be filled with a monetary amount. Leaving the amount blank would make the finding incomplete and legally unenforceable. The system will prompt the user to enter a value if the checkbox is selected but the amount is missing.

Conditional Hardship Details Entry

This check verifies that if a hardship category (e.g., 'Other minor children') is checked in section 4, at least one of the currency fields for Petitioner, Respondent, or Other Parent/Party contains a value. Simply checking the box without specifying the financial hardship amount for a party makes the entry incomplete. This ensures that any claimed hardship is properly quantified for the support calculation.

Child's Date of Birth is in the Past

This validation confirms that each 'Date of birth' entered for a child in the table in section 6a is a valid date that occurs before the current date. This prevents typographical errors, such as entering a future date or an impossible date. An invalid date of birth would impact the calculation of the support termination date and must be corrected.

Common Mistakes in Completing FL-342

The ones the AI is built to catch.

Confusing Gross and Net Monthly Income
In Section 2a, individuals often incorrectly enter their take-home pay (net) in the 'Gross monthly income' field, or vice versa. This happens due to a misunderstanding of the terms, where 'gross' is pre-tax income and 'net' is post-tax/deduction income. This error fundamentally skews the guideline support calculation, leading to an incorrect child support order that may require a court hearing to fix. Always use your total earnings before any taxes or deductions for gross income.
Inaccurate Time-Share Percentage Calculation
Parties frequently estimate the time-share percentages in Section 3b, resulting in totals that do not equal 100% or that don't accurately reflect the custody schedule. Since this percentage is a critical factor in the child support formula, even a small error can significantly alter the support amount. To avoid this, calculate the number of hours the child spends with each parent over a year and divide by the total hours in a year (8,760) to get an accurate percentage. AI-powered form fillers like Instafill.ai can include calculators to help ensure these figures are accurate.
Forgetting to Complete the Header on Every Page
This form has three pages, and each page includes a header for Petitioner, Respondent, and Case Number. It is a very common clerical error to fill out the header on the first page but leave it blank on subsequent pages. This can cause processing delays or rejection by the court clerk, as each page must be clearly identifiable with the correct case. Always double-check that the case number and party names are filled in at the top of every single page before submission.
Making Contradictory Selections for Additional Support
In Sections 6b and 6c, for costs like childcare or medical expenses, the form requires choosing to pay either a percentage of the total cost OR a flat monthly dollar amount. A frequent mistake is checking both boxes or filling in both fields for the same parent and expense. This creates an ambiguous and unenforceable order. You must choose only one method of payment per item to ensure the order is clear.
Failing to Attach Required Printouts and Forms
The form references several other documents that must be attached, such as the computer calculation printout (Section 1) or the Non-Guideline Child Support Findings Attachment (Section 6d). People often check the box indicating an attachment is included but then forget to physically attach it to the filing. This renders the order incomplete and can lead to rejection or the need for a new hearing. Create a checklist of all mentioned attachments to ensure everything is included with your submission.
Improperly Claiming Hardship Deductions
In Section 4, individuals may claim a hardship deduction without meeting the strict legal criteria or without entering the specific monthly dollar amount of the hardship. For example, simply having other children does not automatically qualify as a hardship; specific circumstances must apply. This can lead to the court disallowing the deduction and recalculating support. Ensure you understand the legal definition of a hardship and provide all required financial details and documentation.
Omitting Critical Base Support Payment Details
When filling out the Base Child Support table in Section 6a, people sometimes list the child's name and monthly amount but forget to check the box indicating which parent must pay, the name of the person receiving the payment, and the payment start date. Omitting any of these details makes the support order vague and difficult to enforce. Carefully review this section to ensure every component of the order is explicitly defined.
Overlooking the Mandate to File a Case Registry Form
Section 13 explicitly states that both parties must file a Child Support Case Registry Form (FL-191) within 10 days of the order. This is a separate, mandatory requirement that is often missed because it's located in the 'Notices' section near the end of the form. Failure to file this form can result in non-compliance with court rules. Using a tool like Instafill.ai can help by flagging instructions for related forms that need to be filed.
Entering Vague or Unenforceable 'Other Orders'
The 'Other orders' field in Section 11 is intended for specific, clear, and enforceable agreements not covered elsewhere on the form. A common mistake is to write vague statements like 'Parents will split extracurricular costs' without defining what those costs are or the exact percentage split. This leads to future disputes. Any entry in this section should be as specific as a contract, detailing who does what, by when, and how.
Using a Non-Fillable PDF Leading to Illegible Entries
Often, court forms are only available online as flat, non-fillable PDFs, forcing users to print them and fill them out by hand. This frequently results in illegible handwriting, which can cause data entry errors by court staff or outright rejection of the form. To prevent this, use a service like Instafill.ai, which can convert any flat PDF into an interactive, fillable form, ensuring all your entries are clear, legible, and correctly formatted.
