How to Provide Proof of Debt in Singapore (2026): Online Filing, Form 23 vs Form 77, Deadlines & Supporting Documents

If you are a creditor owed money by a bankrupt individual or a company in liquidation in Singapore, understanding how to provide proof of debt is the single most important step to protecting your claim. The process is governed by the Insolvency, Restructuring and Dissolution Act (IRDA), and since the commencement of the Simplified Insolvency Programme 2.0 (SIP 2.0) and related IRDA subsidiary legislation on 29 January 2026, creditors now benefit from streamlined e-services and clearer procedural timelines. This guide consolidates every step, from choosing the correct form and assembling proof of debt supporting documents, to filing online via the MinLaw Insolvency Office (IO) e-service and responding to a rejection, into one practitioner-level resource for 2026.

Quick Answer, Can You File Proof of Debt Online in Singapore?

Yes. Creditors in Singapore can file a proof of debt online through the Ministry of Law’s Insolvency Office e-service. The process is fully digital, and the standard filing fee is SGD 5 per proof of debt submitted, as recorded on the MinLaw Insolvency Office creditor information page.

TL;DR, what you need to know right now:

• Where to file: MinLaw Insolvency Office e-service portal (accessible online with Singpass or registered login credentials).
• Which form: Use Form 23 for bankruptcy/individual estate claims or Form 77 for company winding-up claims, see the comparison table below.
• What changed in 2026: SIP 2.0 subsidiary legislation (effective 29 January 2026) introduced simplified processes and enhanced digital filing workflows administered by the Insolvency, Restructuring and Dissolution Authority (IRDA Singapore).

What Is a Proof of Debt, Legal Effect in Bankruptcy and Liquidation

A proof of debt is a prescribed claim document through which a creditor formally establishes a provable debt against a bankrupt individual or a company being wound up. It serves two critical purposes: it entitles the creditor to vote at meetings of creditors, and it qualifies the creditor to receive a share of any dividend distributions from the insolvent estate.

Not every claim is provable. To qualify, a debt must generally have existed or been contingent at the date of the bankruptcy order or the commencement of winding up. The following types of claims are typically provable:

• Liquidated debts: Fixed, ascertainable sums such as outstanding invoices, loan balances and contractual payments.
• Unliquidated claims: Claims where the exact amount has not been determined but a valid basis for the obligation exists (e.g., pending damages claims).
• Contingent debts: Obligations that depend on a future event, such as guarantees that may or may not be called upon.
• Future debts: Debts not yet due at the relevant date but contractually certain to fall due.

Filing a proof of debt is not optional, a creditor who fails to submit one cannot participate in votes or claim a dividend, regardless of the size of the debt owed.

Key 2026 Changes, SIP 2.0 and IRDA Singapore Reforms That Affect Creditor Filings

The Simplified Insolvency Programme 2.0 (SIP 2.0), together with related IRDA subsidiary legislation, took effect on 29 January 2026. These reforms, administered by the Insolvency, Restructuring and Dissolution Authority (IRDA Singapore), introduced meaningful operational changes for creditors lodging proofs of debt.

What changed for creditors in 2026:

• Enhanced digital filing: The IO e-service platform was updated to support more intuitive form completion, improved document upload workflows and real-time filing status tracking.
• Simplified timelines: SIP 2.0 streamlined procedural timelines for smaller insolvencies, meaning creditors may encounter shorter filing windows, prompt action is essential.
• IRDA oversight: The IRDA now exercises consolidated regulatory oversight over insolvency practitioners and processes, providing creditors with clearer escalation channels if disputes arise over admitted claims.

Industry observers expect these changes to reduce processing delays for straightforward claims and to make the overall proof of debt experience considerably more accessible for creditors filing without professional representation. However, the tighter timelines also mean that late filings are more likely to be excluded, making awareness of deadlines more critical than ever.

When to File, Deadlines and Timing for Proof of Debt in Singapore

The deadline for filing a proof of debt depends on the type of insolvency proceeding. In every case, the appointed liquidator, trustee in bankruptcy, or official assignee will publish a notice specifying the cut-off date. Missing this deadline can mean losing your right to vote and, in some cases, your entitlement to a dividend.

Key timing principles

The liquidator or trustee typically sets the proof of debt deadline by notice published in the Government Gazette and served on known creditors. In practice, the notice period is usually at least 21 days, but this can vary. Creditors should treat the deadline stated in the notice as absolute and file well before it expires.

Practical tip: If you receive a notice inviting you to file a proof of debt, calendar the deadline immediately and aim to submit at least five business days before it expires. Technical issues with the online portal, incomplete evidence or missing authority documents can all cause last-minute delays.

Which Form to Use, Form 23 vs Form 77 for Proof of Debt in Singapore

Choosing the correct form is a frequent source of confusion, particularly for first-time filers. In Singapore, the two principal forms used to file proof of debt are Form 23 (used primarily in bankruptcy and individual estate proceedings) and Form 77 (used in company winding-up proceedings). The table below provides a practical side-by-side comparison.

Quick guidance: If the insolvency notice you received relates to an individual bankruptcy, use proof of debt Form 23. If it relates to a company being wound up, use Form 77. When in doubt, contact the appointed liquidator or trustee, filing the wrong form can delay adjudication of your claim.

Step-by-Step Online Filing via MinLaw IO E-Service, How to File Proof of Debt and Pay SGD 5

The MinLaw Insolvency Office e-service is the primary digital platform for creditors to submit their proofs of debt. The following numbered steps walk you through the process from start to confirmation.

1. Access the IO e-service portal. Navigate to the MinLaw IO creditor e-service page. Singapore-based users can log in using Singpass. Overseas creditors or corporate entities may need to register for a portal account if one has not already been created.
2. Locate the correct estate or insolvency case. Use the case reference number or debtor’s name from the notice you received. Select the relevant bankruptcy or winding-up case from the search results.
3. Select the appropriate form. The portal will prompt you to select the correct proof of debt form, Form 23 for bankruptcy/individual estate or Form 77 for company winding-up. Ensure you select the form that matches the type of proceeding.
4. Complete the form fields. Enter the required information field by field:
   • Your full name and address (as creditor), or the corporate creditor’s registered name and address.
   • The debtor’s name and the case reference number.
   • The nature and amount of the debt, including the date it was incurred.
   • Whether the debt is secured, unsecured, preferential or contingent, and, if secured, full particulars of the security held.
   • Details of any payments received on account of the debt.
5. Upload supporting documents. Attach scanned copies of all evidence supporting your claim (see the “Supporting Documents” section below for a detailed list by creditor type). Accepted file formats typically include PDF, JPEG and PNG. Ensure individual file sizes comply with the portal’s upload limits, large files may need to be compressed or split.
6. Verify and digitally sign. Review all fields for accuracy. The form must be signed, the portal supports digital/electronic signatures. If filing on behalf of a corporate creditor, ensure you attach the authority document (board resolution or power of attorney) alongside your signature.
7. Pay the filing fee. The filing fee is SGD 5 per proof of debt. Payment is made online through the portal at the point of submission.
8. Receive confirmation. Upon successful submission and payment, the portal will generate a confirmation receipt and reference number. Save or print this receipt, it serves as proof that you filed within the deadline and may be needed for future correspondence with the liquidator or trustee.

Troubleshooting tips

• File format errors: Convert documents to PDF before uploading. Scanned images should be clear and legible, blurred or truncated documents may be rejected by the reviewing officer.
• Upload size limits: If the portal limits individual uploads, split large document bundles into clearly labelled parts (e.g., “Supporting Documents, Part 1 of 3”).
• Session timeouts: Long forms may time out. Draft your responses offline first, then paste them into the portal fields to reduce the risk of data loss.
• Overseas creditors: If you cannot access Singpass, contact the IO helpdesk or the appointed insolvency practitioner for alternative submission instructions.

Proof of Debt Supporting Documents, What to Attach and Evidence Standards

The strength of your proof of debt depends directly on the quality of the supporting documents you attach. Insufficient evidence is one of the most common reasons for rejection or provisional admission. The following lists set out the documents typically expected for each creditor type.

Unsecured trade creditors

• Signed contracts or purchase orders
• Tax invoices and delivery orders
• Statements of account showing the outstanding balance
• Correspondence confirming the debt (e.g., demand letters, email acknowledgements from the debtor)

Secured creditors

• All documents listed for unsecured creditors, plus:
• Security agreements (mortgage instruments, charges, pledges)
• Registered charge documents from ACRA (if applicable)
• Valuation reports for the secured asset
• Statement of the amount claimed, distinguishing between the secured portion and any unsecured shortfall

Judgment creditors

• Certified copy of the court judgment or order
• Writ of execution or other enforcement documents (if applicable)
• Statement of amounts recovered to date

Contingent creditors and guarantors

• The guarantee or indemnity agreement
• Evidence of the underlying obligation (e.g., the loan facility to which the guarantee relates)
• Demand notices served under the guarantee
• Statement of the contingent amount claimed

Documents from overseas, authentication requirements

• Notarised copies of original documents
• Certified English translations (where originals are in a language other than English)
• Evidence of chain-of-title if the debt was assigned (deed of assignment, notice of assignment to the debtor)
• Apostille or consular legalisation where required by the nature of the document

Early indications from practitioners suggest that since the SIP 2.0 changes, the reviewing standards for supporting documents have become more systematic, with IO officers and appointed liquidators cross-referencing uploaded evidence against the claim amounts more rigorously. Providing a clear, indexed bundle, rather than a single unsorted PDF, significantly improves the chances of prompt admission.

Costs, Signature and Authority, Who Can Sign on Behalf of a Creditor

The filing fee for a proof of debt in Singapore is SGD 5 per form submitted, payable online at the point of submission via the IO e-service portal. There are no additional government fees for standard filings, though professional advisory costs (if you engage a lawyer or insolvency practitioner to prepare the claim) are separate.

Signature and authority requirements:

• Individual creditors: Sign the form personally or through a duly appointed attorney (attach the power of attorney).
• Corporate creditors: An authorised director, company secretary or officer must sign. Attach a board resolution or written authorisation confirming the signatory’s authority to file the proof of debt on behalf of the company.
• Agents and solicitors: If filing through a solicitor or agent, attach the written authority or retainer letter confirming the appointment.

What Happens After You File, Review, Acceptance, Voting Rights and Distributions

Once you file a proof of debt, the process moves into the hands of the appointed liquidator, trustee in bankruptcy or official assignee. Understanding this post-filing phase is essential for managing expectations and protecting your position.

Adjudication of claims

The liquidator or trustee reviews each proof of debt against the debtor’s books and the evidence submitted. Claims are typically dealt with in one of three ways:

• Admitted in full: The claim is accepted at the stated amount. The creditor is entitled to vote at meetings and to receive dividends.
• Admitted in part (provisionally): Only a portion of the claim is accepted, often because the liquidator considers some evidence insufficient. The creditor can supply additional documents to support the balance.
• Rejected: The claim is disallowed entirely. The creditor is notified in writing with reasons for the rejection.

Voting rights

Admitted creditors may vote at meetings on matters such as the appointment of a liquidator, approval of the liquidator’s fees, or proposals for a scheme of arrangement. Voting entitlements are usually proportional to the admitted claim amount.

Dividend distributions

When realised assets are available for distribution, dividends are paid to admitted creditors according to the statutory priority waterfall. Secured creditors are paid from the proceeds of their security, while unsecured creditors share pro rata in the remaining estate. Distribution timelines vary widely depending on the complexity of the estate and the number of claims.

If Your Proof of Debt Is Rejected, Review, Appeal and Court Challenge

A rejection is not necessarily the end of the road. Creditors whose proofs of debt are rejected have several practical options to pursue.

1. Request a written explanation. The liquidator or trustee is required to provide reasons for the rejection. Study these carefully, the rejection may be based on a specific evidentiary gap that can be remedied.
2. Supply additional evidence. If the rejection relates to insufficient documentation, gather and submit the missing evidence promptly. Communicate clearly with the liquidator and confirm receipt.
3. Request a formal review. If you disagree with the rejection after supplementing evidence, request that the liquidator reconsider the decision formally. Put your request in writing and reference the specific grounds of disagreement.
4. Appeal to the court. If the rejection stands after review, a dissatisfied creditor may apply to the court to reverse the liquidator’s decision. Court applications involve legal costs and procedural requirements, obtaining insolvency-specialist legal advice before commencing proceedings is strongly recommended.

The likely practical effect of the 2026 IRDA reforms is that the IRDA’s consolidated oversight role provides creditors with a clearer escalation pathway if they believe the appointed insolvency practitioner has acted unreasonably in rejecting a claim.

How to Check Bankruptcy or Winding-Up Status and Proof of Debt Receipts

After filing, creditors often need to verify the status of the insolvency proceeding or confirm that their proof of debt was received and is being processed. Several tools are available to help you check bankruptcy status in Singapore:

• IO e-service portal: Log back in to the MinLaw Insolvency Office e-service and check your filing history. Confirmation receipts and case status updates are typically accessible from your account dashboard.
• Insolvency register: The IRDA maintains registers of bankruptcy orders and winding-up orders. These can be searched to confirm the current status of the debtor’s case.
• AskGov.sg: The MinLaw Q&A page on AskGov.sg provides answers to frequently asked questions about the proof of debt process and case status enquiries.
• Direct contact: Contact the appointed liquidator, trustee or official assignee directly using the contact details in the insolvency notice. For regulatory concerns, the IRDA’s general enquiries contact is published on the IRDA website.

Note that access to certain bankruptcy records may be restricted for privacy reasons. Searches by members of the public (as opposed to creditors of record) may return limited information.

Practical Examples and Model Wording for How to Provide Proof of Debt

The following sample wording illustrates how to describe different types of debts in the relevant field of your proof of debt form. These are simplified examples, adjust the details to match your actual claim.

Example 1, trade debt (unsecured)

“The debt of SGD 45,000 arises from the supply of goods under Purchase Order No. PO-2025-1234 dated 15 March 2025 and Invoice No. INV-2025-5678 dated 22 March 2025. Payment was due within 30 days of invoice. No payment has been received. Supporting documents attached: signed purchase order, tax invoice, delivery order and statement of account.”

Example 2, judgment debt

“The debt of SGD 120,000 arises from Judgment dated 10 October 2025 in Suit No. DC/DC 9999/2025 entered in the State Courts of Singapore. No amount has been recovered under execution. Supporting documents attached: certified copy of the judgment and writ of execution.”

Example 3, secured claim

“The debt of SGD 500,000 arises from Facility Agreement dated 1 June 2024 between [Creditor] and [Debtor]. The debt is secured by a registered charge over [description of asset], registered as Charge No. [reference]. The estimated value of the security is SGD 350,000. The unsecured shortfall claimed is SGD 150,000. Supporting documents attached: facility agreement, charge instrument, ACRA charge registration extract, and independent valuation report dated 5 January 2026.”
