Compliance FL-191
Validation Checks by Instafill.ai

1
Validates Social Security Number Format
This check ensures that all Social Security Number fields (for the father, mother, and each child) are entered in the standard XXX-XX-XXXX format. Correct formatting is critical for the national database lookup and record matching as mandated by the Social Security Act. If the format is incorrect, the submission will be rejected with an error message prompting the user to correct the entry.
2
Ensures Date of Birth is in the Past
This validation verifies that the dates of birth entered for the father, mother, and all children are valid calendar dates that occur before the current date. A future date of birth is logically impossible and indicates a data entry error. If a future date is entered, the system will prevent submission and highlight the field for correction.
3
Conditional Requirement for Filer's Information
Based on whether 'Mother' or 'Father' is checked at the top of the form, this validation ensures that the corresponding section (Section 6 for Mother, Section 5 for Father) is fully and accurately completed. The instructions state the filer is required to provide information about themselves. Failure to complete the required section will prevent form submission until the missing information is provided.
4
Logical Consistency of Restraining Order Parties
For Section 7, this check verifies that the party being restrained (7b) is not the same as a party being protected (7a). For example, if 'Father' is checked in 7b ('From'), 'Father' cannot also be checked in 7a ('The order protects'). This prevents a logical contradiction in the order's details. An error will be displayed if the same party is selected in both fields.
5
Conditional Requirement for Restraining Order Details
If the primary checkbox in Section 7 ('A restraining order...is in effect') is checked, this validation makes subsections 7a, 7b, and 7c mandatory. The system needs to know who is protected, who is restrained, and when the order expires to be a complete record. If the main box is checked but the details are missing, the user will be prompted to complete all three subsections.
6
Validates Restraining Order Expiration Date
This check ensures the date entered in Section 7c for the restraining order's expiration is a valid date and is in the future. An expired order would not typically be noted as 'in effect', so a past date suggests an error. This ensures the registry has accurate information on current, active protective orders, and will flag past or invalid dates for user review.
7
Conditional Requirement for Wage Withholding Stay Date
In Section 1c(5), if the 'ordered but stayed until' option is selected for wage withholding, this validation ensures that the corresponding date field is not empty. The date indicates when the stay is lifted and is critical for enforcement. If the option is checked without a date, the form submission will be blocked until a valid future date is entered.
8
Mutually Exclusive Support Amount Entry
In Section 1c(1), for each support type (Child, Family, Spousal), this check ensures a user cannot enter a dollar amount AND check the 'Reserved order' or '$0 (zero) order' box simultaneously. These options are mutually exclusive. If a user enters an amount, the checkboxes should be cleared, and vice-versa, to prevent contradictory data.
9
Requires Selection of Filer's Role
This validation confirms that the user has selected either the 'Mother' or 'Father' checkbox at the top of page 1. This selection is mandatory as it identifies the person completing the form and is essential for other validations, such as ensuring the correct party's information section is filled out. The form cannot be submitted until one of these roles is identified.
10
Validates Standard Phone Number Format
This check verifies that all telephone number fields on the form adhere to a standard format, such as (XXX) XXX-XXXX or XXX-XXX-XXXX. Consistent formatting improves data quality and ensures the contact information is usable for communication and record-keeping. Entries that do not match the expected format will be flagged for correction.
11
Requires Signature and Date for Perjury Declaration
This validation ensures that the signature and date fields at the end of page 2 are both completed before submission. The signature under penalty of perjury is a legal requirement affirming the truthfulness of the provided information. The form is considered incomplete and legally invalid without a signature and date, so submission will be blocked until they are provided.
12
Logical Date Relationship Between Parent and Child
This check compares the date of birth of each child (Section 4) against the dates of birth of the mother (Section 6) and father (Section 5). A child's date of birth must be at least 12-14 years after the parent's date of birth to be biologically plausible. This helps catch significant data entry errors, such as transposed years, and will flag inconsistent dates for review.
13
Conditional Requirement for Employer Information
In Sections 5g and 6g, if the 'Employed' checkbox is selected, this validation makes the employer's name, address, and telephone number fields mandatory. This information is vital for income verification and potential wage withholding orders. If 'Employed' is checked but the employer details are missing, the user will be prompted to provide them.
14
Completeness Check for Child Information
For each child listed in Section 4, this check ensures that the child's name, date of birth, and social security number are all provided. Incomplete records for a child can cause issues with support calculation and federal reporting. The system should prompt the user to complete all three fields for every child row that has been started.

Common Mistakes in Completing FL-191

Confusing Support Types and Amounts

Users often misinterpret the columns for 'Child Support,' 'Family Support,' and 'Spousal Support' in Section 1c. They may enter a child support amount in the family support column or vice-versa. This mistake leads to incorrect case setup in the state registry, potentially affecting tax implications and how support is enforced and distributed. To avoid this, carefully reference the exact language and amounts specified in your court order for each category of support.

Incorrectly Reporting 'Additional Monthly Support'

In Section 1c(2), filers are asked for a fixed monthly amount for costs like child care or medical expenses, but often enter variable percentages (e.g., '50% of daycare') or leave it blank if the cost isn't fixed. The state system cannot process non-specific percentages, so these obligations will not be tracked or enforced through the registry. Only enter a specific dollar amount if the court order defines one; otherwise, leave this field blank.

Mixing Up Total Past-Due Support and Monthly Payments on Arrears

Section 1c contains separate fields for 'Total past-due support' (arrears) and 'Payment on past-due support' (the monthly installment). A common error is to enter the total arrears amount in the monthly payment field, or vice versa. This significantly misrepresents the financial obligations and can cause major confusion in the state's accounting and enforcement efforts. Double-check your court order to distinguish between the total balance owed and the monthly payment amount.

Omitting Required Personal Identifiers

Many people are hesitant to provide Social Security Numbers (for themselves and their children) and driver's license numbers in Sections 4, 5, and 6 due to privacy concerns. However, the form states this information is mandatory and will be kept confidential. Omitting these numbers severely hampers the state's ability to enforce the support order, especially if a parent moves out of state, as SSNs are the primary tool for locating individuals and processing wage garnishments. AI-powered tools like Instafill.ai can help by flagging mandatory fields to ensure they are not accidentally skipped.

Providing Incomplete or Incorrect Employer Information

When filling out employer details in Sections 5g or 6g, individuals often list a generic business name (e.g., 'Starbucks') instead of the full legal name of the employing corporation or franchise. They may also provide the address of the local branch instead of the corporate headquarters where payroll is processed. This leads to returned or rejected wage withholding orders, delaying support payments. To prevent this, use the full employer name and address found on a recent pay stub.

Failing to Mark the Form as an Update

When submitting changes to previously provided information, filers often forget to check the 'Change to previous information' box at the top of page 1. They simply fill out the form with the new data. This can cause the state agency to create a duplicate case file instead of updating the existing one, leading to significant administrative confusion, conflicting records, and potential errors in support enforcement. Always check this box if you have submitted an FL-191 for this case before.

Forgetting to Complete the Header on Page 2

The top of Page 2 requires the user to re-enter the party names and the case number. Because this is repetitive, it is frequently overlooked. If the pages become separated during clerical processing, Page 2 becomes an 'orphan' document with no identifiable information, meaning all the personal and employment data on it is lost. This requires the court to request a new form, causing delays. Using a tool like Instafill.ai can automatically populate repeated fields across a document, preventing this error.

Submitting an Unsigned or Undated Form

Forgetting to sign and date the form under penalty of perjury at the bottom of Page 2 is a simple but critical mistake. An unsigned form is legally invalid and will be rejected by the court clerk upon submission. This invalidates the entire filing and requires the user to resubmit, delaying the registration of the child support case. Always perform a final review, making the signature and date the last step before submission.

Misunderstanding the Submission Deadline and Process

The form instructions state that if you were not the party who filed the court order, you must deliver this form to the court within 10 days of receiving the order. Many individuals miss this instruction, assuming the other party or the court will handle it, or they submit it late. Failure to comply can delay the establishment of the case with the state enforcement agency and may be considered non-compliance with court procedures.

Incorrectly Filling Out the Parent Information Sections

The form has separate sections for 'Father' (Section 5) and 'Mother' (Section 6), but the instructions clarify that the person completing the form should only fill out the section that applies to them. A common mistake is for a father to fill out his information in Section 5 and then also fill out what he knows about the mother in Section 6. The form is designed for each parent to submit their own information separately, so providing second-hand data can lead to inaccuracies and confusion. Since this form is often a non-fillable PDF, using a service like Instafill.ai can convert it into an interactive, guided experience to help prevent such structural misunderstandings.
