Frequently Asked Questions About Form FM-Mod1-101

This form is used to respond to a 'Petition to Modify' that has already been filed against you. It allows you, the Respondent, to ask the court for your own changes to the existing orders for custody, visitation, or child support.

You are the 'Counter-Petitioner' because you are filing this counter-request for changes. The 'Counter-Respondent' is the person who filed the original 'Petition to Modify' against you.

You will need the cause number and court information from the original petition, the title and date of the current court order, and personal details for yourself and the children. You should also have information about health insurance and any public benefits the children have received.

Standing is your legal right to file a case regarding the child. In Section 5, you must select your relationship to the child (e.g., parent, grandparent) to prove to the court that you are legally permitted to request a modification.

You can still ask, but you must meet a higher legal standard as outlined in Section 6. You will need to attach a separate 'Declaration' form and show that the child's current environment is harmful, the other parent agrees to the change, or another specific condition applies.

Yes, if your child receives or has ever received Medicaid or TANF, you must send a copy of this filed Counter-Petition to the Office of the Attorney General's Child Support Division. You must then sign the 'Certificate of Service' in Section 24 to confirm you have done this.

You must formally deliver a copy of the filed form to the other party (or their attorney) as required by Texas Rules of Civil Procedure, Rule 21a. This legal notification process is called 'service'.

Section 22 allows you to ask the court to keep your personal information, such as your home address and phone number, confidential. Check the boxes in this section if you fear harassment or harm, and the court can order that information be protected.

'Conservatorship' refers to legal custody rights, like who makes major decisions for the child and determines where they live. 'Possession and Access' refers to the specific visitation schedule that details when each parent has the child.

Yes, Section 21 requires you to disclose any existing or pending protective orders involving you, the other party, or a child of a party. You must provide the case details and may be required to attach a copy of the order.

This is the legal reason required to change a court order, as mentioned in Section 9. It means a significant life event has occurred since the last order was made, such as a parent's relocation, a major change in income, or new needs of the child.

Compliance FM-Mod1-101
Validation Checks by Instafill.ai

1
Petitioner Identification Completeness
This check ensures that the petitioner provides either the last three numbers of their driver's license or the last three numbers of their social security number. If the petitioner indicates they have neither, the form can be accepted. This is crucial for court identification purposes and to prevent fraudulent filings. Failure to provide one of these identifiers when available will result in a validation error prompting the user to complete the required information.
2
Child Information Completeness
For each child listed in Section 3, this validation verifies that the child's name, a valid date of birth, and the county/state of current residence are all provided. Incomplete information for any child can delay the case and lead to incorrect court orders. If any of these three fields are missing for a listed child, the submission will be rejected until all information is supplied.
3
Current Order Date Validity
This validation checks that the date entered for when the current court order was signed (Section 4) is a valid, correctly formatted date and that the date is in the past. This date is essential for establishing the timeline and jurisdiction of the modification request. An invalid format or a future date would be nonsensical and will cause the form to be rejected, requiring the user to input a valid historical date.
4
Standing Sub-Option Requirement
In Section 5, if the petitioner checks the box indicating they are a grandparent or other relative, this validation ensures they also check one of the required sub-options (e.g., 'both parents are dead'). This is a legal requirement to establish standing to file the case. A failure to select a required sub-option will prevent submission and prompt the user to specify the legal basis for their standing as a relative.
5
Custody Change Within One Year Logic
This check validates the logic in Section 6. If the user checks 'I am asking to change primary custody and it has been less than one year,' it then requires that one of the subsequent four reasons is also checked. Furthermore, it flags that a 'Declaration in Support of Changing Primary Custody within One Year' form must be attached. This is critical because changing custody within a year has a higher legal burden, and failure to provide the required justification and attachment will result in the request being denied.
6
Conservatorship Selection Consistency
This validation ensures that if 'I ask the Court to change conservatorship (custody)' is checked in Section 10, then one of the specific conservatorship arrangements (options a, b, c, d, e, or f) must also be selected. Conversely, if 'I do not want to change conservatorship' is selected, all subsequent conservatorship options must be disabled or cleared. This prevents contradictory or incomplete requests regarding custody, ensuring the court receives a clear petition.
7
Out-of-State Party Affidavit Requirement
This check verifies that if the user selects 'Someone involved in this case... does not live in Texas' in Section 8, the system flags that a completed 'Out-of-State Party Affidavit' must be attached to the submission. This affidavit is legally required to address jurisdictional issues under the Uniform Child Custody Jurisdiction and Enforcement Act (UCCJEA). The submission will be considered incomplete without this required attachment.
8
Support Modification Specificity
This validation applies to Sections 14, 15, and 16 (Child, Medical, and Dental Support). If the user checks that they want to change any type of support, they must then specify the nature of that change (e.g., 'Father should be ordered to pay more child support'). A general request to change support without specifics is ambiguous. The validation will fail if the initial box is checked but no specific change is requested, forcing the user to clarify their request.
9
Public Benefits and OAG Service Link
This check creates a logical link between Section 19 and Section 24. If the user indicates that the child(ren) have ever received Medicaid or TANF, the system requires that the 'Certificate of Service to the Office of the Attorney General (OAG)' in Section 24 is signed and dated. This is a mandatory legal step to ensure the OAG, which may have a financial interest in the case, is properly notified. The form cannot be successfully filed without this certification if public benefits were received.
10
Protective Order Attachment Verification
This validation triggers if any option in Section 21C ('Protective Order in Place') is checked. It flags the submission to verify that a copy of the specified protective order has been attached to the petition. This is a critical safety and legal requirement, as existing protective orders can significantly impact custody and visitation decisions. The system will issue a warning or hold the submission if the attachment is missing.
11
Joint Managing Conservator Exclusivity
In Section 10, if 'Mother and Father should be Joint Managing Conservators' is selected, this check ensures that mutually exclusive sub-options are not selected. For example, the user cannot select both 'a-1. Father should have the exclusive right to designate the primary residence' and 'a-2. Mother should have the exclusive right...'. This prevents logical contradictions in the custody request, ensuring the petition presents a coherent plan to the court.
12
Counter-Respondent Completeness
This validation applies to the Counter-Respondent sections (B, C, and D) in Section 7. If the checkbox indicating the existence of a Counter-Respondent B, C, or D is selected, the corresponding field for their full name must be filled out. This ensures that all legally required parties to the case are properly identified from the outset. The form will be considered incomplete if a party is declared but not named.
13
Conditional 'Other' Field Requirement
This check applies to multiple sections where an 'Other' option is available (e.g., Section 5, 7, 10). If an 'Other' checkbox is selected, the corresponding text field for explanation must contain text. This prevents users from selecting an 'Other' option without providing the necessary details for the court to understand their request. The submission will be blocked until the required explanation is provided.
14
Signature and Contact Information Completeness
This validation ensures that the petitioner's signature, printed name, phone number, and full mailing address are present in the signature block on page 10. These fields are mandatory for the document to be legally valid and for the court and other parties to be able to contact the petitioner. A submission without this complete information will be rejected.

Common Mistakes in Completing FM-Mod1-101

Incorrectly Copying Case Information

Users often make typos or enter incomplete information in the 'Cause Number' and court details section at the top of the form. This happens because they are copying from another document and may misread the number or fail to include the exact court name. An incorrect cause number can lead to the filing being rejected by the clerk, delaying the legal process significantly. To avoid this, double-check that the cause number and court information are copied exactly as they appear on the original 'Petition to Modify' that was filed.

Misunderstanding Legal 'Standing'

Section 5, 'Standing,' is a complex legal section that people frequently get wrong, especially non-parents. They may check a box that does not accurately reflect their legal relationship or the circumstances required by law, such as the specific timeframes for having care of a child. This is a critical error that can cause the judge to dismiss the case entirely for lack of standing. It is crucial to carefully read the cited Texas Family Code sections or consult an attorney to ensure you qualify under the option you select.

Failing to Attach Required Supplemental Forms

The form requires attaching other documents under specific circumstances, such as the 'Declaration in Support of Changing Primary Custody within One Year' (Section 6) or copies of any protective orders (Section 21). People often overlook these instructions, assuming the main petition is sufficient. Failure to attach these mandatory documents will result in an incomplete filing, causing delays and potentially prejudicing your case. Always review each section for notes about required attachments.

Making Contradictory Custody Selections

In the highly detailed 'Conservatorship (Custody)' section (Section 10), it is easy to make conflicting choices, such as checking boxes giving both the mother and the father the exclusive right to determine the child's residence. This usually happens from rushing through the many checkboxes without reading them carefully. Such contradictions make the request legally unclear and may force the court to disregard the section, leading to an outcome the petitioner did not want. Carefully review all selections in this section to ensure they form a single, coherent request.

Providing Vague Custom Visitation Schedules

When a user selects option 13c, stating the standard visitation is 'unworkable,' they often write vague or emotional descriptions instead of a clear, structured schedule. For example, writing 'whenever we can agree' is not an enforceable order. This forces the judge to guess at the petitioner's intent or create a schedule for them, which may not be what was desired. To avoid this, clearly outline specific days, times, holidays, and exchange locations for the proposed visitation schedule.

Ignoring Insurance Availability Details

After requesting a change to medical or dental support in Sections 15 or 16, many people skip the detailed follow-up questions in Sections 17 and 18 about insurance availability and cost. This information is not optional; the court needs it to apply the Texas Family Code guidelines for setting support amounts. Omitting these details can delay the case, as the court will require the information before it can make a final ruling on support. Be sure to complete these sections fully if you are asking to modify support.

Incorrectly Handling the Attorney General Notification

In Section 19, filers must indicate if a child has ever received Medicaid or TANF, which then requires them to sign the 'Certificate of Service to the Office of the Attorney General (OAG)' in Section 24. A common error is either failing to notify the OAG when required, or signing the certificate when it's not necessary. Failing to notify the OAG when public benefits have been involved can bring the entire case to a halt until the OAG is properly served. Conversely, unnecessarily involving them can add complexity.

Forgetting to List All Necessary Parties

In Section 7, 'Counter-Respondent(s),' a filer might only list the other parent, forgetting other individuals who may have rights under the current order, such as a grandparent conservator. All parties entitled to notice must be included and properly served. Overlooking a necessary party will delay the case, as the court cannot proceed until all parties have been correctly identified and notified of the counter-petition.

Incorrectly Identifying the Current Order

In Section 4, 'Request to Change Current Order,' people often write a generic description like 'Final Custody Order' instead of the exact title found on the first page of the document they wish to modify. The court needs to know precisely which order is being addressed. Using an incorrect or vague title can create confusion and may require you to file an amended petition, causing unnecessary delays. Always locate the exact title on the original court order and copy it verbatim.

Submitting Full Personal Identification Numbers

The form explicitly asks for only the 'last three numbers' of the driver's license or social security number for identification purposes. However, many individuals mistakenly write out the full number. This not only fails to follow instructions but also creates a significant privacy risk, as the document becomes part of the public court record. To protect your sensitive data, read the instructions carefully and provide only the specific information requested. AI-powered tools like Instafill.ai can help prevent this by recognizing and correctly formatting such data fields.
