Frequently Asked Questions About CN 10339
CN 10339 has a Form Complexity Index of 37 out of 100, placing it in the basic 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 CN 10339 specifically, the score reflects 32 fillable fields across 3 pages, plus 1 page of printed instructions. 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 basic score means the form is relatively light, but still needs careful, accurate entry. Instafill removes that effort entirely: our AI reads your information, maps each value to the correct field — including the conditional ones — and completes CN 10339 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.
This form is used to file a legal complaint with the Tax Court of New Jersey to challenge the County Equalization Table. It is typically filed by a municipality that believes its contribution to county costs is unfair due to an incorrect property value ratio.
The plaintiff is the entity challenging the County Equalization Table, which is usually a municipality within the county. An attorney representing the municipality can also file the complaint on its behalf.
In section 4, you must list specific property sales you believe were improperly used by the county and explain why. In section 5, you must list sales that were improperly excluded from the county's study and explain why they should have been included.
The Affidavit of Service is a sworn statement confirming that you have legally delivered a copy of the complaint to all required parties. This includes every municipality in the county, the County Tax Administrator, and the Attorney General.
No, the form's instructions state that its use is optional. However, any complaint you submit must contain all the same information and follow the formatting rules of the Tax Court.
This means you must remove or black out sensitive information like Social Security numbers, driver's license numbers, and financial account numbers from all documents before filing. This is a court rule designed to protect personal privacy.
You must file the original complaint with the Tax Court of New Jersey and serve copies to all parties listed in the Affidavit of Service. Service must be completed via certified mail with a return receipt requested.
While you can represent yourself, this is a formal legal action in Tax Court involving complex valuation principles. It is highly recommended that you consult with or hire an attorney experienced in this area of law.
In this section, you must provide a clear and detailed explanation supporting your appeal. This should include the specific facts, data, and analysis that demonstrate why you believe the county's equalization table is incorrect.
The Docket Number is assigned by the Tax Court after you file the complaint. You will leave this field blank on your initial submission, and the court clerk will fill it in.

Compliance CN 10339
Validation Checks by Instafill.ai
1
Plaintiff Name Presence
This check ensures the Plaintiff's name field (`PlaNameFull`) is not empty. The plaintiff is the primary party initiating the complaint, and their identity is fundamental to the legal action. A submission without a plaintiff name is legally incomplete and would be rejected immediately.
2
County Name Consistency
Verifies that all fields referring to the county name (e.g., `TypeCounty`, `TypeCounty2`, `TypeCounty3`) contain the exact same text. This consistency is critical for the legal document's integrity, as it defines the jurisdiction and subject of the complaint. Mismatched county names would create ambiguity and likely cause the filing to be deemed defective.
3
Valid NJ Attorney ID Format
Validates that the `attyIDNo` field, if provided, conforms to the specific format for New Jersey Attorney ID numbers. This is crucial for correctly identifying the filing attorney and verifying their standing with the bar. An invalid ID can cause processing delays while the court staff manually verifies the attorney's credentials.
4
Valid Email Address Format
Ensures the `attyEmail` field contains a string that conforms to a standard email address format, such as '[email protected]'. This is a critical field for official communication from the court and other parties. An invalid email address will prevent the filer from receiving important case updates, notices, and orders, potentially jeopardizing their case.
5
Required Appeal Basis Narrative
Confirms that the text area for paragraph 3, the facts upon which the appeal is based (`AppealDesc`), is not empty. This section contains the core legal and factual basis for the complaint and is non-optional. A submission without these details is substantively incomplete and provides no grounds for the court to act upon.
6
Valid Ratio Percentage Value
Checks that the value entered for the ratio in paragraph 2 (`ValPercent`) is a valid numerical percentage. The validation should ensure the input is a number, likely within a logical range such as 0-200, as it represents a key data point in the equalization dispute. An invalid or non-numeric entry would undermine the complaint's central claim and require correction.
7
Consistent and Valid Certification Year
Verifies that the year fields related to the certification (`CertYr` and `CertYr2`) are identical and represent a valid, non-future four-digit year. This date is a critical fact in the complaint. Inconsistent or impossible years would create a fatal error in the legal statement, referencing a non-existent or ambiguous record.
8
Affidavit of Service Date Presence
Ensures a date of service (`AffDt`) is provided in the Affidavit of Service section. This date is a legal requirement to prove that all relevant parties were properly and timely notified of the complaint. A missing service date invalidates the affidavit and could lead to the dismissal of the case for improper service.
9
Logical Service Date
Validates that the date of service listed in the affidavit (`AffDt`) is on or after the complaint's signature date (`SigAttyDt`). It is logically and legally impossible to serve a complaint before it has been finalized and signed. This check prevents clerical errors that could call the validity of the service into question during legal challenges.
10
Affidavit Signatory Completeness
Checks that the name of the person making the affidavit (`AffNameFull`) and their signature (`SigAff`) are both present. An affidavit is a sworn statement that is legally meaningless without the identity and attestation of the deponent. A missing name or signature will cause the affidavit, and thus the proof of service, to be rejected by the court.
11
Valid Telephone Number Format
Validates that the `TeleNo` field contains a correctly formatted phone number, such as a 10-digit number with optional standard formatting. This contact information is vital for the court or opposing counsel to communicate with the filer. An incorrectly formatted number can hinder timely communication and cause administrative delays.
12
Redaction Certification Acknowledgment
Verifies that the filer has positively acknowledged their responsibility to redact confidential personal identifiers as required by Rule 1:38-7(b), typically by checking a mandatory box. This check enforces compliance with court rules on privacy and data security. Failure to provide this acknowledgment may halt the submission process until the user confirms their compliance.
Common Mistakes in Completing CN 10339
The form explicitly warns filers to redact personal identifiers like Social Security or driver's license numbers per Rule 1:38-7(b). A common and serious error is submitting the complaint or its attachments without removing this sensitive data. This violates court rules, can lead to the rejection of the filing, and exposes individuals to identity theft. Always double-check all submitted documents for confidential information before filing.
The Affidavit of Service on page 3 is a sworn statement that the complaint was properly delivered to all required parties. People often forget to fill in the date of service, the county name, or fail to list all parties served. An incomplete or incorrect affidavit can invalidate the service, potentially leading to the dismissal of the case on procedural grounds. Carefully follow the instructions and ensure every blank is filled and every required party is listed as served.
In section 3, 'The facts upon which this appeal is based,' filers may provide generic statements like 'the ratio is wrong' without specific, factual support. A complaint must present a clear, fact-based argument to be compelling, and lacking this detail can result in the complaint being dismissed. To avoid this, provide concrete data, calculations, or specific examples that demonstrate the alleged error in the equalization table.
The complaint requires a signature and date on page 2, and the Affidavit of Service requires another on page 3. Forgetting to sign or date either section is a frequent and critical error that can render the document legally invalid. This will cause the court clerk to reject the filing, delaying the case. Always perform a final review of the completed form specifically to check for required signatures and dates.
Sections 4 and 5 require filers to explain why certain sales were improperly used or excluded. A common mistake is to simply list property addresses without providing a detailed legal or factual reason for the challenge (e.g., 'non-arm's length transaction,' 'sale included business assets'). Without this justification, the allegations are unsubstantiated and will likely be disregarded by the court. For each sale listed, provide a concise but complete explanation for why it skews the data.
Paragraph 3 of the Affidavit of Service requires the filer to indicate the method of service on the Attorney General by striking out either 'personally' or 'by registered or certified mail.' Many filers overlook this instruction, leaving both options intact. This ambiguity can call the validity of the service into question. To prevent this, simply cross out the method that was not used before signing.
In this type of complaint, the Plaintiff is the municipality challenging the table, and the Defendant is the County Board of Taxation that created it. Filers, especially those without legal representation, may misunderstand this and reverse the parties or list incorrect entities. This fundamental error can lead to immediate confusion and may require filing an amended complaint, causing delays. Ensure you correctly identify your municipality as the Plaintiff and the relevant County Board of Taxation as the Defendant.
The form requires the county name in at least seven different fields. Filers often make typos or use slightly different naming conventions across these fields, which can create confusion and suggest a lack of attention to detail. This can lead to processing delays or questions about the document's accuracy. To avoid this, carefully proofread all entries for the county name to ensure they are identical, or use a tool like Instafill.ai which can populate recurring information consistently across a document.
This form is presented as a flat, non-fillable PDF, meaning it must be printed and filled out by hand. A very common mistake is submitting a form with illegible handwriting, especially in the detailed narrative sections. If court staff cannot read names, dates, or factual allegations, it can lead to misinterpretation or rejection of the filing. AI-powered tools like Instafill.ai can convert such flat PDFs into fillable forms, allowing you to type your responses and ensure perfect legibility.
Attorneys filing the complaint are required to provide their New Jersey Attorney ID Number. Forgetting to include this ID can cause processing delays as court staff must look up the information to verify the attorney's standing. This simple omission reflects poorly on the filer and can slow down the initial intake of the case. Attorneys should ensure this field is always completed accurately.
