Frequently Asked Questions About Form Supplemental eCourts Proof of Service
This form is used to prove that you have served a hard copy of your Tax Court complaint to individuals or offices that were not served electronically through the New Jersey eCourts system. It supplements your original electronic filing.
You only need to fill out this form if you filed your complaint electronically but had to separately mail or personally deliver a copy to certain parties. If all parties were served electronically through eCourts, you do not need this form.
You may need to serve a hard copy of the complaint to the Clerk and Assessor of the taxing district, the Administrator of the County Board of Taxation, and, if applicable, the record owner of the property.
For each party you served, you must indicate whether you delivered the complaint 'personally' or 'by ordinary mail.' You should cross out the method you did not use, leaving only the one that applies for that specific service.
You typically need to serve the record owner if you are not the owner of the property in question but are filing the complaint, for example, as a tenant who is responsible for paying the property taxes.
You should enter the exact date you mailed the complaint or delivered it in person to that specific individual or office. Use a different date for each party if they were served on different days.
The taxing district is the municipality, such as the city, township, or borough, where the property related to your tax complaint is located.
This form should be filed with the New Jersey Tax Court as part of your case file. It serves as your official record that service was completed on all required parties.

No, the form instructions state that you do not have to serve your complaint on individuals again if they were already served via eCourts. This form is only for proving service to those who were not.
Compliance Supplemental eCourts Proof of Service
Validation Checks by Instafill.ai
1
Signature Date Presence and Format
This check ensures the 'Signature Date' (sigDt) field is not empty and is formatted as a valid date (e.g., MM/DD/YYYY). The signature date is legally required to certify the truthfulness of the statements made on the form. A missing or improperly formatted date would render the proof of service invalid and could lead to the rejection of the filing.
2
Filer Name Presence
This validation verifies that the 'filerName' field, representing the undersigned person, is filled out. An anonymous certification is legally insufficient and invalidates the entire proof of service document. This check ensures accountability and that a specific individual is attesting to the service, as required by the certification statement.
3
At Least One Service Action Required
This check ensures that at least one of the four service sections (Clerk, Assessor, Administrator, or Owner) is completed with a service date. The purpose of the form is to prove service was made, so a completely blank form is meaningless. If no service dates are entered, the form fails to fulfill its function and should be rejected.
4
Clerk Service Section Completeness
This validation is a conditional check that ensures if a date is entered for serving the Clerk ('serveClerkDt'), then the corresponding 'clerkDistrict' field must also be filled in. Providing a date without specifying which taxing district's clerk was served makes the entry incomplete and unverifiable. Failure to provide the district name would result in an error prompting the user to complete the information.
5
Assessor Service Section Completeness
This check verifies that if a date is entered for serving the Assessor ('serveAssessDt'), the 'assessDistrict' field is also completed. Similar to serving the clerk, knowing the date of service is useless without knowing which taxing district's assessor was served. This rule ensures the record of service is complete and legally sound.
6
Administrator Service Section Completeness
This validation ensures that if a date is entered for serving the County Board of Taxation Administrator ('serveAdminDt'), the 'cntyTaxBrd' field is also filled out. The entry is ambiguous and invalid without the name of the specific County Board of Taxation. This check prevents incomplete submissions that would be rejected by the court.
7
Logical Date Chronology
This check compares all entered service dates ('serveClerkDt', 'serveAssessDt', 'serveAdminDt', 'serveOwnerDt') against the 'Signature Date' (sigDt). All service dates must be on or before the signature date. It is logically impossible to certify that you have served a document on a future date, and doing so would invalidate the certification.
8
Prohibition of Future Dates
This validation ensures that no date entered on the form, including all service dates and the signature date, is a date in the future relative to the current date. Entering a future date is a common data entry error and is logically invalid for a form attesting to past actions. This check prevents nonsensical data from being submitted.
9
Valid Date Formatting for All Date Fields
This check iterates through all date fields on the form ('serveClerkDt', 'serveAssessDt', 'serveAdminDt', 'serveOwnerDt', 'sigDt') to confirm they follow a standard and parseable date format. Inconsistent or invalid formats like 'February 1st' or '2/35/2023' can cause system errors and make the legal document ambiguous. This ensures data integrity and compliance.
10
Consistent Taxing District Identification
This validation checks that if both the 'clerkDistrict' and 'assessDistrict' fields are filled out, their values are identical. For a single complaint, the clerk and assessor should belong to the same taxing district. A mismatch likely indicates a data entry error that could cause confusion or legal challenges regarding proper service.
11
Plausible Historical Date
This check ensures that all dates entered are on or after the form's publication date of February 2020. An earlier date would be impossible as it would mean the form was filled out before it was created. This serves as a sanity check to catch significant data entry errors or the use of an incorrect, outdated form.
12
Filer Name Format Validation
This check verifies that the 'filerName' field contains at least two words, separated by a space, to encourage the entry of a full name rather than a single name or initial. While not a strict legal requirement, providing a full name enhances the formality and accountability of the legal certification. It helps prevent ambiguous or incomplete entries like 'John' or 'S'.
Common Mistakes in Completing Supplemental eCourts Proof of Service
This form is exclusively for proving service on parties who were NOT served through the eCourts system. A common mistake is to list all parties, including those already served electronically, which creates a confusing and inaccurate record. This can lead to rejection or questions from the court. To avoid this, carefully read the instructions at the top of the form and only list individuals or entities you served manually via mail or in person.
Each service entry requires the filer to choose between 'personally' or 'by ordinary mail' by striking out the method not used. People often forget this step, leaving the method of service ambiguous and rendering the proof defective. This can invalidate the service and cause significant delays. Always review each entry to ensure you have clearly crossed out the inapplicable service method.
Filers frequently use unofficial abbreviations, misspell, or enter the wrong municipality for the 'taxing district' or 'County Board of Taxation'. This ambiguity can cause the filing to be rejected because it is unclear which legal entity was properly served. To prevent this, always use the full, official name of the municipality and county, and double-check the spelling before submitting.
A critical error is entering the date the form is being signed into the 'On [date], I, the undersigned, served...' field. This field requires the exact date the complaint was actually mailed or delivered, not the date you are filling out the form. An incorrect service date can create an inaccurate legal record and jeopardize your case if deadlines are at issue. Always use the actual date of service for each party.
The date of service is the most crucial piece of information on this form, yet it is sometimes left blank. Without a date, there is no proof of when service occurred, making the entry invalid and potentially leading to a dismissal for failure to serve. Before signing, meticulously check that a service date is entered for every party you manually served. AI-powered tools like Instafill.ai can help by flagging empty required fields before submission.
Filers may inadvertently enter conflicting information, such as spelling the taxing district differently in the Clerk's section versus the Assessor's section. These discrepancies, often caused by typos or haste, can raise doubts about the accuracy of the filing and may require clarification or correction. To avoid this, ensure that recurring information like names and districts are entered identically in all fields. Using a tool that auto-populates recurring data can prevent these inconsistencies.
The certification at the bottom of the form is a sworn statement, and it is invalid without a signature and the date of signing. Forgetting either of these elements is a common oversight that will lead to the form being rejected by the court, delaying the case. Always perform a final check to ensure you have physically or electronically signed the form and entered the current date next to your signature.
Section 4, regarding service on the record owner, is conditional and should only be completed if required by the specific circumstances of the case. Many filers fill it out by default, which can create confusion or imply facts that are not true. You should first determine if service on the record owner is necessary before completing this section. Leaving it blank when it does not apply is the correct procedure.
In an attempt to be thorough, or due to confusion, some individuals strike out both 'personally' and 'by ordinary mail', or neither. This makes it impossible to determine how service was performed. This ambiguity invalidates the proof of service for that entry. To avoid this, make a clear and deliberate choice, striking out only the single method that was not used. Since this form is a non-fillable PDF, tools like Instafill.ai can convert it into an interactive, fillable version, making it easier to clearly edit and manage such options.
