Frequently Asked Questions About APP-106
APP-106 has a Form Complexity Index of 64 out of 100, placing it in the complex complexity tier. This score is calculated deterministically from the form’s own structure using Instafill’s published Form Complexity Index methodology, so it can be reproduced and independently verified — it is not a subjective estimate.
For APP-106 specifically, the score reflects 74 fillable fields across 2 pages, grouped into 28 sections, and 15 conditional fields that only apply depending on earlier answers, 3 tables or repeating lists. The number of fields is the largest factor in the base score (weighted 36%), followed by how difficult those fields are to complete based on their type, where free-text and signature fields count for more than simple checkboxes (26%). The number of pages that actually contain fields (15%), the amount of conditional “fill-only-if” logic (16%), and how many sections the form is divided into (7%) account for the rest of the base. On top of that base, the index adds points for tables and repeating lists, bundled instruction pages, and dense page layouts — capturing difficulty the base alone can miss.
In practical terms, a complex score means the form is demanding, with many fields, multiple pages and branching rules that are easy to get wrong. Instafill removes that effort entirely: our AI reads your information, maps each value to the correct field — including the conditional ones — and completes APP-106 accurately in under a minute, with every field available for you to review before you download. See exactly how the Form Complexity Index is calculated.

Any party in a limited civil case appeal, whether they are the appellant or the respondent, who needs more time to submit their legal brief must fill out this form.
You will need the trial court and appellate division case numbers, the case name, your contact information (or your lawyer's), the current due date of the brief, and the new date you are requesting.

In Section 5, you must disclose all previous extensions, specifying whether they were by agreement of the parties (stipulation) or by a court order, and the total number of days granted.
A stipulation is a formal agreement between the parties. If the other party does not agree to give you more time, you must check the appropriate box in Section 6 and file this application with the court to request an order.

Compliance APP-106
Validation Checks by Instafill.ai
1
Appellate Case Number Consistency
This check ensures that the 'Appellate Division Case Number' entered on page 1 is identical to the 'Appellate Division Case Number' entered in the header of page 2. This is critical for document integrity and correct case file association. A mismatch could lead to the application being rejected or misfiled.
2
Mutually Exclusive Representation Information
Validates that either the party's contact information (Section 1b) or the party's lawyer's information (Section 1c) is provided, but not both. The form instructs the user to skip one section based on representation status. If both or neither are filled, the form is incomplete or ambiguous, and processing will be halted until the filer clarifies their representation.
3
State Bar Number Format
If lawyer information is provided in Section 1c, this check verifies that the 'State Bar number' field contains only numeric characters. This ensures the number is valid and can be used to verify the attorney's standing with the State Bar. An invalid format would prevent verification and may lead to rejection of the form.
4
Exclusive Brief Selection
Verifies that exactly one checkbox is selected in Section 2, which identifies the brief for which an extension is requested. Selecting more than one or none at all makes the request ambiguous. A failure in this validation would require the clerk to return the form for clarification, delaying the extension request.
5
Conditional Due Date Entry
This check ensures that the date field corresponding to the selected brief in Section 2 is filled out. It also validates that the entry is a valid date format. Without the original due date, the court cannot determine the length of the requested extension or if the request is timely.
6
Prospective Extension Date
Ensures the requested new due date in Section 3 is a valid date that occurs after the original due date provided in Section 2. Requesting an extension to a date that has already passed is a logical error. This validation prevents illogical requests from being submitted for court review.
7
Extension Days Calculation
Validates that the 'total number of days sought' in Section 3 is a positive integer. It can also perform a soft validation to check if the number of days roughly corresponds to the difference between the original due date (Section 2) and the requested new date (Section 3). This ensures the filer's request is internally consistent and clearly stated.
8
Conditional Previous Extension Details
If the filer checks 'Has been extended before by the stipulation of the parties' or 'Has been extended before by the court' in Section 5, this check ensures the corresponding 'number of extensions' and 'totaling number of days' fields are filled with positive integers. This information is required by the court to evaluate the current request in the context of the case's history.
9
Required Explanation for 'Other' Reason
In Section 6, if the 'Other reason' checkbox is selected to explain why a stipulation was not possible, this validation ensures the accompanying text field is not empty. The court requires a specific reason to be provided in this scenario. An empty field would render the application incomplete and likely result in denial or a request for more information.
10
Mandatory Extension Justification
Confirms that the text field in Section 8, which explains the reason for needing an extension, is not left blank. This justification is the core of the application and is required for the court to make a decision. Failure to provide a reason will result in an automatic denial of the request.
11
Past Date for Last Filed Brief
Validates that any date entered in Section 9 for a previously filed brief is a valid date that occurs on or before the current submission date. A future date for a past event is a logical impossibility. This check maintains the chronological accuracy of the case record presented in the application.
12
Conditional Lawyer Certification
This check verifies that the lawyer certification checkbox in Section 10 is checked if the lawyer information section (1c) has been completed. Per rule 8.810(e), the lawyer must certify they have provided a copy to their client. Failure to check this box when represented by counsel would make the application non-compliant with court rules.
13
Signature Name Verification
Cross-references the name typed in the signature block ('Type or print your name') against the party's name (Section 1a) and the lawyer's name (Section 1c). The signature name must match the name of the individual filing the form (either the party themselves or their attorney). A mismatch could indicate an unauthorized filing and lead to rejection.
Common Mistakes in Completing APP-106
Filers often mistakenly enter the Trial Court Case Number in the field for the Appellate Division Case Number, or vice versa. This happens because they are not aware that a new case number is assigned when a case is appealed. This error can lead to filing delays, misdirection of the document, or outright rejection by the clerk's office. To avoid this, carefully check the notice of appeal and other documents issued by the appellate division court for the correct number.
A frequent error is for self-represented parties to fill out the lawyer's information in section 1(c), or for parties with a lawyer to fill out their personal contact details in section 1(b). The form explicitly says to skip the section that doesn't apply, but people often overlook these instructions in their haste. This causes confusion for the court and opposing parties about who to contact regarding the case. Always read the instructions for each section carefully before entering information.
In Section 8, many applicants provide vague or weak justifications like 'I need more time' or 'I have been busy with work.' The court requires a specific, compelling reason that addresses the factors in rule 8.811(b), such as the complexity of the issues, counsel's engagement in other cases, or personal emergencies. A weak justification is the most common reason for the court to deny the extension, forcing the brief to be filed by the original deadline or risk default. Be detailed and honest about why the extension is necessary.
Applicants often complete the case information on the first page but forget to repeat the Appellate Division Case Name and Number in the header of the second page. This is a simple oversight but can cause significant processing problems if the pages become separated at the courthouse. To prevent this, make it a habit to review every page of the form for completeness before filing. AI-powered form fillers like Instafill.ai can help by automatically populating repeated information across all pages of a document.
In Section 5, filers may forget or misstate the number and length of previous extensions, whether granted by the court or by agreement (stipulation) of the parties. This can be seen as an attempt to mislead the court, even if unintentional, and may result in the denial of the current request. Before filling out this section, thoroughly review all prior correspondence and court orders in the case to ensure the information is completely accurate.
A critical mistake is filing the application with the court but failing to 'serve' a copy on all other parties in the case. The court will not consider an application until it has confirmation that the other parties have been properly notified. Forgetting this step or failing to file a separate Proof of Service form (like APP-109-INFO) will lead to the application being rejected, wasting valuable time. Always follow the instructions for service detailed on the form.
Forgetting to sign and date the application in the signature block at the end of page 2 is a simple but fatal error. An unsigned legal document is invalid and will be immediately rejected by the court clerk, as if it were never filed at all. This can cause you to miss your filing deadline entirely. Always perform a final review of the completed form, paying special attention to the signature and date fields before you print or file.
In Section 3, applicants must state the new date they want the brief to be due and the total number of days for the extension. It is common for there to be a mismatch between the date provided and the number of days calculated. This clerical error creates ambiguity and may lead the court to grant a shorter extension than intended. To avoid this, use a calendar to carefully count the days and double-check that your math is correct.
Section 4 asks whether the filer has received a default notice from the clerk under rule 8.882(c), which is a warning that the brief is late. Many filers, especially those without legal training, may not understand what this notice is or may not remember receiving one, leading them to check the wrong box. Misrepresenting this critical fact can have serious consequences for the appeal, so it is vital to review all notices from the court before answering.
For applications filed by a lawyer, Section 10 contains a mandatory certification that the lawyer has provided a copy of the application to their client. Attorneys, in their rush, sometimes forget to check this box, which is a violation of court rules (rule 8.810(e)). This can result in the form's rejection or sanctions from the court. Attorneys should use a filing checklist to ensure this and all other requirements are met. Using a tool like Instafill.ai, which can convert flat PDFs into fillable forms, can help ensure all checkboxes and fields are addressed.
