The AI fills all of it, from your answers or your documents.

Form N349, Application for Third Party Debt Order, is an official UK court form (Crown copyright 2020) that enables a judgment creditor to apply to the court for an order requiring a third party — typically a bank or building society — to pay money it holds on behalf of the judgment debtor directly to the judgment creditor, up to the amount owed under a court judgment or order. The form requires details about the judgment debtor, the outstanding debt, the third party's account information, any other interested parties, and the grounds for the application, all verified by a Statement of Truth. It is an important enforcement tool in civil litigation, allowing creditors to recover debts without relying on the debtor's voluntary compliance. Today, Form N349 can be filled out quickly and accurately using AI-powered services like Instafill.ai, which can also convert non-fillable PDF versions into interactive fillable forms.

The AI checks your answers before you download

16 checks built for this form, so a wrong date or a missing answer is caught before anyone else sees it.

Claim Number Format and Consistency Across Sections

Validates that the claim number entered in the court header section matches the claim number entered in the 'Order and claim details' section, and that both conform to the standard UK court claim number format (e.g., A1BC2345 or a numeric sequence). Discrepancies between the two claim number fields could indicate a clerical error or that the application references the wrong case. If the claim numbers do not match or are improperly formatted, the application may be rejected or processed against the wrong judgment.

Judgment Order Date is Valid and Not in the Future

Checks that the day, month, and year fields for the date the judgment or order was given combine to form a valid calendar date (e.g., not 31 February or 00/00/0000) and that the resulting date is not in the future. A future-dated judgment would be legally impossible and would indicate a data entry error. The year field must also be a plausible four-digit year when combined with the '20' prefix, falling within a reasonable historical range.

Judgment Amount and Amount Now Due Are Positive and Logically Consistent

Validates that both the original judgment amount (including costs and interest) and the amount now due are positive numeric values greater than zero, and that the amount now due does not exceed the original judgment amount unless further interest has been explicitly indicated. If the amount now due is greater than the original judgment amount without the further interest checkbox being selected, this represents a logical inconsistency that could undermine the application. Both fields must be present and formatted as valid currency amounts in pounds sterling.

Instalment Fields Completeness and Mutual Exclusivity

Ensures that exactly one of the two instalment options is selected: either the 'judgment did not provide for payment by instalments' checkbox is checked, or the instalment amount fields (amount of instalments fallen due and unpaid) are completed with a valid positive monetary value. If the instalment option is selected, the corresponding monetary amount must be provided and must not exceed the amount now due. Selecting both options simultaneously or leaving both blank creates an ambiguous and incomplete application.

Third Party Identification: Bank/Building Society vs. Non-Bank Mutual Exclusivity

Validates that the form clearly identifies the third party as either a bank or building society (with the corresponding bank-specific fields completed) or as a non-bank/building society entity (with the alternative name and England and Wales address fields completed), but not both simultaneously. Each path requires its own mandatory fields: the bank path requires at minimum the institution name and head office address, while the non-bank path requires the third party's name and address in England and Wales. Failure to clearly distinguish the type of third party will prevent the court from properly serving the interim order.

Bank Account Number and Sort Code Consistency

Checks that if the account number 'not known' checkbox is unchecked, a valid account number is provided in the adjacent field, and similarly that if the sort code 'not known' checkbox is unchecked, a valid sort code in the standard UK format (XX-XX-XX or six consecutive digits) is entered. Providing a sort code without an account number, or vice versa, reduces the utility of the information and may prevent the bank from identifying the correct account. Both fields must be internally consistent with their respective 'not known' checkbox states.

Common Mistakes in Completing N349

The ones the AI is built to catch.

Confusing the roles of claimant, defendant, and judgment creditor/debtor
Many applicants fail to correctly identify which party is the 'judgment creditor' and which is the 'judgment debtor,' especially when the defendant is the one seeking enforcement. The form requires selecting whether the claimant or defendant is the judgment creditor, and getting this wrong invalidates the application. Carefully read the bracketed options in the opening paragraph and cross out the inapplicable terms. AI-powered form filling tools like Instafill.ai can help by guiding you through these role selections based on your case details.
Entering incorrect or mismatched claim numbers
The form has two separate fields for claim numbers — one in the header section and one in the order details section — and applicants frequently enter different or inconsistent numbers across these fields, or confuse the original claim number with an application number. This can cause the court to be unable to locate the underlying judgment, delaying or invalidating the application. Always verify the exact claim number from the original court judgment or order and ensure it is entered identically in both locations. Tools like Instafill.ai can auto-populate repeated fields to prevent inconsistencies.
Providing inaccurate or outdated judgment debt amounts
Applicants often enter the original judgment amount rather than the current amount now due, failing to account for additional interest accrued since the judgment was made. The form requires two distinct figures: the original amount ordered and the current outstanding balance including further interest. Failing to update these figures can result in the order being made for the wrong amount, potentially prejudicing the judgment creditor. Always calculate the current balance including accrued interest up to the date of the application before completing these fields.
Incorrectly completing the instalment payment section
Many applicants either leave the instalment section blank when it applies, or fill it in when the judgment did not provide for instalments, creating a contradiction on the form. If the judgment was for a lump sum with no instalments, only the 'did not provide for payment by instalments' checkbox should be ticked; if instalments were ordered, the unpaid instalment amount must be specified. Completing both options simultaneously or leaving the section ambiguous can cause the application to be rejected. Read the conditional instructions carefully and only complete the fields that apply to your specific judgment.
Omitting or incorrectly entering third party bank account details
Applicants frequently leave the account number and sort code fields blank without ticking the 'not known' checkbox, or they enter incorrectly formatted sort codes (e.g., omitting hyphens or entering digits in the wrong order). Courts and banks require these details to freeze the correct account, and errors can result in the wrong account being targeted or the application being returned. If the details are genuinely unknown, always tick the 'not known' checkbox rather than leaving the field empty. Instafill.ai can validate sort code formats and flag missing mandatory selections automatically.
Failing to provide adequate sources and grounds of information in Section 5
Section 5 is frequently left vague or nearly blank, with applicants writing only 'personal knowledge' or 'bank statements' without explaining how they know the third party holds money for the judgment debtor. Courts require sufficient detail to satisfy themselves that the application is well-founded, and an inadequate explanation can lead to the application being dismissed. Applicants should specify the source (e.g., bank statements, correspondence, credit reference searches) and explain when and how the information was obtained. Providing clear, specific evidence-based reasoning in this section significantly strengthens the application.
Not disclosing other persons' interests in Section 4
Applicants often tick 'None' in Section 4 without properly considering whether any other person — such as a joint account holder, trustee, or secured creditor — may have a claim to the money held by the third party. Failing to disclose known third-party interests is a breach of the duty of candour and can constitute a false statement in the Statement of Truth, potentially leading to contempt of court proceedings. Carefully consider all parties who may have an interest in the funds before completing this section, and if in doubt, seek legal advice. Erring on the side of disclosure is always safer than omitting relevant information.
Failing to disclose previous third party debt order applications in Section 6
Judgment creditors who have previously applied for third party debt orders against the same debt sometimes forget to disclose these prior applications, either because they were unsuccessful or because they occurred some time ago. The form requires full disclosure of all previous applications, and omitting them constitutes a false statement verified by the Statement of Truth. Always check your records for any prior enforcement applications before completing Section 6, and if previous applications were made, provide full details including the third party's name, address, and relevant dates.
Signing the Statement of Truth in the wrong capacity
Applicants frequently tick the wrong signatory category — for example, ticking 'judgment creditor' when they are actually signing as a legal representative, or failing to tick any category at all. The Statement of Truth must be signed by the correct person in the correct capacity, and an incorrectly attributed signature can render the document invalid. If signing as a legal representative, the firm name and position held must also be completed. Carefully read all three signatory options and select only the one that accurately reflects your role before signing.
Entering an incomplete or incorrectly formatted contact address for correspondence
The address section at the bottom of the form — to which court documents will be sent — is often completed with missing fields such as the town/city or postcode, or applicants enter a personal address when a solicitor's address should be used. An incomplete address means the court cannot serve documents, causing significant delays in the proceedings. Ensure all mandatory address fields (building and street, town or city, and postcode) are fully completed, and use the legal representative's address if one is acting. Instafill.ai can validate address completeness and postcode formats to prevent these errors.
Omitting the date or entering an incomplete date on the Statement of Truth
The date field on the Statement of Truth is split into three separate boxes (day, month, year) and applicants frequently leave one or more boxes blank, enter only the year, or write the date in the wrong format. An undated Statement of Truth may be treated as defective by the court, potentially requiring the application to be resubmitted. Ensure all three date components are completed in full using numeric values (e.g., Day: 15, Month: 03, Year: 2024). AI-powered tools like Instafill.ai can automatically populate and validate date fields to prevent this common oversight.
Incorrectly completing the third party section when the third party is not a bank
When the third party is not a bank or building society, applicants sometimes still complete the bank-specific fields (account number, sort code, branch details) or fail to use the alternative non-bank section of the form, creating confusion about the nature of the debt. The form has distinct sections for bank/building society third parties and non-bank third parties, and only the relevant section should be completed. If the third party is not a financial institution, complete only the non-bank section with the third party's name and England and Wales address. Carefully read the conditional instructions at the start of Section 3 to determine which fields apply to your situation.

What is Form N349 and what is it used for?
Form N349 is an Application for a Third Party Debt Order, used by a judgment creditor to recover money owed to them under a court judgment. It instructs a third party (such as a bank or building society) that holds money belonging to the judgment debtor to pay that money directly to the judgment creditor instead.
Who should fill out this form?
This form should be completed by the judgment creditor — the person or organisation who has already obtained a court judgment or order requiring the judgment debtor to pay them money. It can also be completed by the judgment creditor's legal representative on their behalf.
What information do I need before completing this form?
You will need the original claim number and court details, the date and amount of the judgment or order, the judgment debtor's full name and address, and details about the third party (such as the bank's name, head office address, branch details, account number, and sort code). You should also be prepared to explain the sources and grounds for your belief that the third party holds money for the judgment debtor.
What if I don't know the judgment debtor's bank account number or sort code?
The form allows you to indicate that the account number or sort code is 'not known' by checking the relevant boxes. However, providing as much detail as possible — including the bank name, head office address, and branch — will help the court process your application more efficiently.
Can I apply for a third party debt order against a non-bank third party?
Yes. If the third party is not a bank or building society, you should complete the section of the form that asks for the third party's name and their address in England and Wales. The third party must be located within England and Wales and must owe money to, or hold money to the credit of, the judgment debtor.
What should I enter in the 'Sources and grounds of information' section?
In Section 5, you should explain why you believe the information provided in Sections 3 and 4 is accurate. This might include bank statements you have seen, information provided by the judgment debtor, correspondence, or other evidence that confirms the third party holds money for the judgment debtor.
What happens if other people also have a claim to the money held by the third party?
In Section 4, you must disclose any other persons (besides the judgment debtor) who have a claim to the money held by the third party, along with their names, addresses, and details of their claims. If no other persons have a claim, simply check the 'None' box.
What is the Statement of Truth and why is it important?
The Statement of Truth is a declaration that the facts stated in the application are true to the best of your knowledge and belief. Signing it carries serious legal weight — making a false statement in a document verified by a Statement of Truth can result in contempt of court proceedings.
Who can sign the Statement of Truth on this form?
The Statement of Truth can be signed by the judgment creditor themselves, a litigation friend (if the judgment creditor is a child or a patient), or the judgment creditor's legal representative as defined by CPR 2.3(1). The appropriate box must be checked to indicate who is signing.
Do I need to disclose previous applications for third party debt orders?
Yes. Section 6 requires you to declare whether you have made any previous applications for third party debt orders in respect of the same judgment debt. If you have, you must provide details of those applications, including the third party's name and address.

Where do I submit the completed N349 form?
The completed form should be submitted to the court where the original judgment or order was made, along with the appropriate court fee. You should check with the relevant court for specific submission instructions, as requirements may vary by court location.
What does 'amount now due' mean in Section 2, and how is it different from the original judgment amount?
The original judgment amount is the total the court ordered the judgment debtor to pay, including costs and interest at the time of the judgment. The 'amount now due' is the current outstanding balance, which may be higher if further interest has accrued since the judgment was made, or lower if partial payments have already been received.
