The AI checks your answers before you download

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

Case Information Completeness

This check ensures that the Judicial Circuit, County, Case Number, and Division fields are all populated. These fields are essential for the clerk of court to correctly file the document and associate it with the proper legal case. A failure to provide this information will result in the form being rejected for filing.

Net Monthly Income Presence and Format

Validates that the 'Present Net Monthly Income' fields for both the Petitioner and Respondent (Line 1) contain non-negative, numeric values. This income is the foundational figure for all subsequent calculations. If the data is missing, non-numeric, or negative, the entire worksheet is invalid and cannot be processed.

Number of Children Validation

Ensures that the 'number of minor child(ren)' field (Line 2) is populated with a positive integer (e.g., 1, 2, 3). This number is critical as it determines which column of the guidelines chart is used for the calculation. An empty or non-integer value would make it impossible to determine the basic child support obligation.

Basic Obligation Chart Lookup Verification

This check cross-references the total net monthly income (Line 1 Total) and the number of children (Line 2) with the provided 'Child Support Guidelines Chart'. It verifies that the 'Basic Monthly Obligation' amount entered on Line 2 is the correct value from the chart. An incorrect value here invalidates all subsequent calculations and could lead to a legally incorrect support amount.

Financial Responsibility Percentage Calculation

Verifies that the percentages on Line 3 are calculated correctly (Parent's Income / Total Income) and that their sum equals 100%. This ensures the financial responsibility is proportionally and completely allocated between the parties. If the percentages are wrong or do not sum to 100%, the division of the support obligation will be incorrect.

Share of Obligation Calculation

This validation confirms that each parent's 'Share of Basic Monthly Obligation' on Line 4 is the correct product of the total obligation (Line 2) and their respective percentage (Line 3). It also checks that the sum of the parents' shares on Line 4 equals the total basic obligation on Line 2. This is a crucial check to ensure the mathematical integrity of the core support calculation.

Common Mistakes in Completing Form 12.902(e)

The ones the AI is built to catch.

Miscalculating Monthly Income from Pay Stubs

The form requires all income to be converted to a monthly figure, but people with non-monthly pay schedules often make errors. They might multiply weekly pay by 4 or bi-weekly pay by 2, both of which are incorrect and result in under-reporting income. The correct method is to multiply weekly pay by 52 and divide by 12, or multiply bi-weekly pay by 26 and divide by 12. An incorrect income figure invalidates the entire worksheet and can lead to the court rejecting the filing.

Using Gross Income Instead of Net Income

Line 1 of the worksheet specifically requires the 'Present Net Monthly Income' from the corresponding Financial Affidavit (Form 12.902). A frequent mistake is entering the gross (pre-tax) income instead. This significantly inflates the income base for the calculation. This error leads to a drastically incorrect and often unfairly high child support obligation, which will be contested and require correction, delaying the case.

Manual Calculation and Rounding Errors

The worksheet is filled with multi-step calculations, including percentages (Line 3), multiplication (Line 4), and a complex series of additions and subtractions to reach the final obligation. Simple arithmetic mistakes, misplaced decimals, or incorrect rounding are extremely common when done by hand. These errors lead to an inaccurate final support amount that is not compliant with state guidelines, requiring correction and refiling. AI-powered tools like Instafill.ai can prevent this by performing all calculations automatically and accurately.

Incorrectly Applying or Skipping the Substantial Time-Sharing Calculation

If each parent has the children for at least 20% of overnights (73 per year), the 'Gross Up Method' calculation (Lines 10-21) is mandatory. Many filers either don't know this rule, find the calculation too complex and skip it, or apply it when it's not appropriate. Using the wrong calculation method results in a legally incorrect child support amount that the court cannot approve, leading to mandatory revisions and significant delays.

Inaccurate Calculation of Overnight Time-Sharing Percentages

When the Substantial Time-Sharing section applies, Line 12 requires calculating the precise percentage of overnights each parent has. People often guess, estimate, or make mathematical errors when dividing the number of overnights by 365. Since this percentage is a critical multiplier in the 'Gross Up' formula, even a small error can significantly alter the final support obligation, leading to disputes and recalculations.

Misstating Child Care and Health Insurance Costs

Lines 5 and 14 require the monthly costs for child care and the child(ren)'s portion of health insurance. A common error is to list the cost for a full family health plan rather than isolating the child-only cost. Another is to include unapproved child care expenses. These inflated costs wrongly increase the total support obligation and can be a major point of contention, requiring proof and correction. It is crucial to only include documented, child-specific expenses.

Using Inconsistent Data from the Financial Affidavit

The worksheet is a companion to the Financial Affidavit, and the income figures must match perfectly. Filers sometimes enter a different income number on the worksheet than what they filed on their affidavit, creating a critical discrepancy. Courts and opposing counsel check for this consistency, and a mismatch will lead to the form being rejected, raise questions about the filer's credibility, and halt the case until the forms are consistent.

Misreading the Child Support Guidelines Chart

To find the 'Basic Monthly Obligation' on Line 2, one must use the combined net income and the number of children to find the correct value in a large grid. It is easy to look at the wrong row or column, especially with six columns for different numbers of children. Selecting the wrong value from the chart makes the foundational number for all subsequent calculations incorrect, invalidating the entire worksheet.

Incomplete or Incorrect Certificate of Service

The Certificate of Service on the first page is a legal requirement to prove a copy was sent to the other party. Filers often forget to sign it, enter the date of service, or check the box indicating how it was delivered (e-mail, mail, or hand-delivery). An incomplete certificate can invalidate the filing, as the court has no proof the other party was properly notified, causing the clerk to reject the document or a judge to disregard it.

Submitting a Poorly Prepared or Illegible Form

This form is often available as a non-fillable PDF, leading people to fill it out by hand. This frequently results in illegible handwriting, numbers that are hard to read, and calculation errors. A messy or unreadable form makes it difficult for the judge and opposing party to verify the information and calculations. A court may reject an illegible filing, requiring the party to resubmit a clear and typed version. Tools like Instafill.ai can convert the PDF into a fillable version, ensuring the final document is clean, professional, and easy to read.
