How to File and Prove a Creditor's Claim in Bulgarian Insolvency Proceedings (2026)

A creditor claim insolvency bulgaria filing is now shaped by a moving legal landscape: Bulgaria’s adoption of the euro on 1 January 2026 and related procedural adjustments have altered how creditors value, denominate and prove their claims. This guide sets out the procedure for filing and proving a creditor’s claim in Bulgarian insolvency proceedings, aimed at corporate creditors, in-house counsel, foreign claimants and debt-collection practitioners who must comply with statutory deadlines and evidentiary standards. It covers submission, valuation (including 2026 euro conversion), the required documentary bundle, court verification, and participation in creditors’ meetings.

Every procedural step is grounded in national procedural rules and EU insolvency law, with time spans expressed as indicative ranges rather than firm promises, since case-specific deadlines are set by the court’s opening order.

Overview, What is a creditor claim insolvency Bulgaria filing?

A creditor claim insolvency bulgaria submission is the formal act by which a person owed money by an insolvent debtor asserts that debt for verification and eventual satisfaction from the debtor’s estate. In Bulgaria, corporate insolvency (bankruptcy) proceedings are governed principally by Part Four of the Commercial Act (Търговски закон), operating alongside Regulation (EU) 2015/848 on insolvency proceedings where a cross-border element exists. Claims fall into broad categories: secured claims (backed by mortgage, pledge or assignment), preferential or privileged claims (including certain state and employee claims), and ordinary unsecured claims.

Quick Process Map

1. Insolvency is opened by court decision and entered in the Commercial Register (and, where relevant, published in the State Gazette).
2. Creditors file written claims with the trustee within the statutory window.
3. The trustee compiles lists of accepted and rejected claims, which are published in the Commercial Register.
4. Objections are lodged and resolved by the court.
5. Creditors’ meetings are convened; voting rights follow accepted claim values.
6. The estate is realised and distributed by priority rank.

Who should read this guide (domestic vs foreign creditors)

Domestic creditors will find the procedural steps and cost indications directly applicable. Foreign creditors face additional layers, translation, apostille or legalisation, appointment of a local representative, and cross-border service, and should read the foreign-creditor notes in each section carefully. A creditor claim insolvency bulgaria matter with an international dimension almost always benefits from local counsel to bridge language, notarisation and registry requirements.

Eligibility, Which creditors can file and deadlines to watch

Any person or entity holding a monetary claim against the debtor as at the date the insolvency proceedings are opened may file. This includes contractual creditors (suppliers, lenders, service providers), tort claimants with a quantified damages claim, and state or municipal bodies asserting tax or other public receivables. The pivotal cut-off is the date the court opens insolvency: claims that arose before that date are lodged for verification, while post-commencement obligations incurred by the trustee in managing the estate are treated as estate liabilities with different standing.

Filing within the statutory period is critical. Under the Commercial Act, creditors must generally lodge their claims with the trustee within a defined period running from entry of the opening decision in the Commercial Register; claims filed after that initial period but within a further statutory grace period may still be admitted, subject to consequences for costs and ranking. A creditor claim insolvency bulgaria filing lodged promptly after entry in the register secures the claimant’s place on the creditors’ list and reduces risk. Always check the specific deadlines stated in the court’s opening decision.

Special rules for secured creditors (pledge/mortgage)

Secured creditors must do more than assert the debt, they must prove the existence and priority of their security. This means producing the registration extract from the relevant register (the Property Register at the Registry Agency for mortgages, the Central Register of Special Pledges for registered special pledges, or the Commercial Register for certain corporate charges). A secured claim that is properly registered and evidenced takes priority in distribution from the proceeds of the specific charged asset; a security interest that cannot be evidenced as perfected will typically be treated as unsecured.

Foreign creditors, service and representation requirements

Foreign creditors retain full standing under the EU Insolvency Regulation, which requires that known foreign creditors be informed and permitted to lodge claims. In practice, a foreign creditor should appoint a Bulgarian representative under a notarised and (where required) apostilled power of attorney, obtain certified Bulgarian translations of supporting documents, and ensure that any cross-border service is documented. Where the debtor’s centre of main interests is in Bulgaria, the Bulgarian proceedings will be the main proceedings for recognition purposes across the EU.

Step-by-step: How to file a creditor claim insolvency Bulgaria

The following steps form the operational core of a creditor claim insolvency bulgaria filing. Each step states what to do, who is responsible, and how long it typically takes. The consolidated timeline table follows the narrative.

Step 1, Monitor insolvency publication and obtain case number

Insolvency openings are entered in the Commercial Register maintained by the Registry Agency and, for defined categories, published in the State Gazette. Monitor these sources continuously if you have a live receivable against a Bulgarian debtor. On identifying an opening, extract the case number, the identity of the appointed trustee, the competent court, and the deadlines stated in the opening decision. This step typically takes 1–3 days from publication.

Step 2, Prepare the claim statement (form, particulars, calculation)

The claim is lodged in writing with the trustee. It must identify the creditor and debtor, state the amount claimed (principal and interest calculated to the opening date), specify the legal and factual basis of the debt, and indicate whether the claim is secured, preferential or unsecured. For foreign creditors the statement should be in Bulgarian or accompanied by a certified translation. Drafting this document typically takes 3–7 days.

A well-drafted claim statement includes a clear calculation table: principal, contractual interest rate, the period over which interest accrued, and the resulting interest figure. Where the underlying obligation is in a foreign currency, include the conversion methodology (see the 2026 euro section below).

Step 3, Assemble the evidentiary bundle

Bulgarian courts and trustees assess claims on documentary evidence. Assemble a chronological bundle: the contract and any amendments, invoices, delivery or acceptance notes, payment records, correspondence evidencing the debt, and, for secured or judgment creditors, the security registration extracts or the authenticated judgment. Reconcile the bundle so the outstanding balance is demonstrable line by line. Collecting and organising documents realistically takes 3–14 days depending on record quality.

Step 4, Lodge the claim with the trustee and the competent court

Claims are lodged with the trustee (receiver) in the insolvency; the trustee then processes them for inclusion in the lists submitted to the court handling the case (the competent district or city court exercising commercial jurisdiction over the debtor’s seat). Where electronic submission is available it may be used; otherwise file in hard copy. Retain the stamped copy or electronic acknowledgement as proof of the filing date, this is decisive for meeting the statutory window.

Step 5, Serve documents and prove service

Keep time-stamped proof that your claim reached the trustee and, where required, other parties, postal receipts, delivery certificates or electronic delivery logs. For any cross-border service that may be required, the applicable EU Service Regulation or bilateral routes should be followed and documented. Domestic delivery typically takes a few days; cross-border channels take longer.

Step 6, Responding to verification objections and disputes

The trustee compiles lists of accepted and rejected claims, which are published in the Commercial Register. Any interested party, the debtor, the trustee, or another creditor, may object to a claim within the period fixed by law once the lists are published. If your claim is disputed, you must respond with focused submissions and, where a valuation is contested, be prepared for a court-appointed expert. A creditor claim insolvency bulgaria dispute that is well documented at the outset is far easier to defend at this stage.

Step 7, Registering claims in the creditors’ list and attending meetings

Once verification concludes and the court approves the lists, accepted claims are recorded. Acceptance confers the right to attend and vote at creditors’ meetings, where voting weight follows the accepted claim value. Attend in person or by a properly authorised proxy; remote participation is limited and should not be assumed.

Required documents, complete checklist and examples

The strength of a creditor claim insolvency bulgaria filing is determined largely by the documentary bundle. The table below lists the standard documents, their source, and the translation, notarisation and apostille requirements. Present the bundle chronologically with a reconciliation schedule that ties each document to the amount claimed.

For secured claims, additional registration/priorities evidence

Secured creditors should annex a current extract from the relevant register showing the security interest, its date of registration, and its ranking. The date of registration/perfection determines priority against competing security holders, so the extract must be recent and unambiguous. Where the security was created abroad or governed by foreign law, expect additional evidence and translation requirements.

For judgment creditors, authenticated judgments and enforcement records

A judgment creditor should submit the authenticated judgment together with any relevant certificate, apostille or legalisation, and a certified Bulgarian translation. Attach evidence of any enforcement steps already taken. Even with a final judgment, the court may examine the claim, so present the chain of documents completely rather than relying on the judgment alone.

Timeline and deadlines, what you must meet

Deadlines in a creditor claim insolvency bulgaria matter are driven by the court’s opening decision and the statutory framework in the Commercial Act. The filing window runs from entry of the opening decision in the Commercial Register. A further statutory grace period may permit later filing, with consequences for ranking and costs. Because these periods are governed by statute and stated in the opening decision, always read the opening decision rather than relying on generic timeframes.

Typical calendar from opening to distribution

• Opening: Insolvency opening entered in the Commercial Register; obtain case number and trustee details.
• Initial filing window: Prepare and lodge the claim statement and bundle within the statutory period from entry.
• Verification: Trustee compiles and publishes lists of accepted and rejected claims; objection period runs.
• List approval and meetings: Court rules on objections and approves the lists; creditors’ meetings are convened.
• Realisation and distribution: Assets are realised and distributed by priority rank, timing depends heavily on the estate’s complexity.

Deadlines for foreign creditors and interest accrual rules

Foreign creditors should build extra lead time for apostille, legalisation and certified translation, these steps alone can add one to several weeks. Interest is generally calculated up to the date the insolvency is opened; interest accruing after that date is treated differently and may not rank equally with the principal. Calculate and evidence interest precisely to the opening date to avoid rejection of part of the claim.

Costs and fees, counsel, court, notary, translation, registry

Costs in a creditor claim insolvency bulgaria filing can rise where translation, legalisation and expert valuation are required. The table below gives indicative ranges only; actual amounts depend on the case, the court tariff in force, and service providers. For a fuller breakdown of legal costs, see Debt collection lawyer fees in Bulgaria (2026).

When a lawyer is mandatory or strongly recommended

Representation by a Bulgarian lawyer is not strictly mandatory for lodging a claim, but it is strongly recommended for foreign creditors and for any claim involving disputed valuation, security perfection, or a foreign judgment. Local counsel manages translations, notarisation, registry contact and objection responses, and can attend creditors’ meetings by proxy.

Recoverability of costs in distribution

Costs are met from the estate in order of priority. Trustee remuneration and certain administrative costs rank ahead of general distributions. Unsecured creditors frequently do not recover their own legal costs where the estate is insufficient, so weigh anticipated recovery against the cost of pursuing the claim before committing to expensive steps.

What changes in 2026, euro conversion, valuation and personal-insolvency impacts

Bulgaria adopted the euro on 1 January 2026, which is the defining change for a creditor claim insolvency bulgaria filing this year. Claims previously denominated in Bulgarian leva are expressed in euro using the official irrevocably fixed conversion rate and the statutory changeover rules. Conversion and rounding are governed by the applicable EU Council regulation fixing the rate and the national changeover legislation; the Bulgarian National Bank and the State Gazette are the authoritative Bulgarian sources. The European Commission’s guidance on introducing the euro sets out the general framework applied at national level.

How to calculate converted claim amounts, worked approach

Where a claim is stated in leva, apply the official fixed conversion rate and round in accordance with the statutory rounding rule. In your submission, present a two-line table: the original leva amount and the converted euro figure, citing the applicable rate. Where the underlying obligation is in a third currency (for example US dollars), convert using the reference rate applicable on the relevant statutory date and document the source. Interest accrued to the opening date should be converted on the same basis and shown separately from principal.

Practical implications for distribution and priority

Conversion does not alter the rank of a claim, but errors in conversion can lead to part-rejection or under-recording of the claim value, which in turn reduces voting weight at creditors’ meetings and the eventual distribution. Trustees are likely to scrutinise conversion methodology during the first insolvency cycles after adoption, so a transparent, source-cited calculation is the single most effective protection against dispute.

Common pitfalls and how to avoid them

• Late filing. Missing the statutory window can prejudice the claim’s ranking or admissibility; monitor the Commercial Register and file within the period in the opening decision.
• Unauthenticated evidence. Uncertified copies and untranslated foreign documents are routinely rejected; obtain apostille/legalisation and certified translation before filing.
• Incorrect euro valuation. Applying the wrong rate or rounding after the euro switch under-records the claim; use the official fixed rate and cite the statutory basis.
• Failing to appoint local counsel. Foreign creditors who attempt to navigate registry and language requirements alone often miss procedural steps; instruct a Bulgarian representative early.
• Not proving security. A secured claim without a current registration extract may be treated as unsecured; annex the ranking evidence.
• Weak interest calculation. Interest not calculated precisely to the opening date invites part-rejection; show the full computation.

Pre-filing checklist, last-minute fixes before filing

Before lodging, confirm: the claim amount is stated in euro with a cited conversion; all foreign documents carry apostille/legalisation and certified translation; the power of attorney is notarised; the reconciliation ties every document to the balance; and you hold proof of the filing date. A short pre-filing review of these items resolves the majority of avoidable rejections.

Tips for foreign creditors (power of attorney, trusted local agent)

Foreign creditors should execute a clear, notarised power of attorney (apostilled or legalised where required) authorising a named Bulgarian representative to file, respond to objections and vote at meetings. Provide the representative with your SWIFT/BIC details for any distribution, and keep an open communication line during the verification window so objections can be answered within the deadline. For an overview of accelerated recovery routes that may run alongside insolvency, see Fast-track Debt Collection Bulgaria (2026).

Conclusion

A successful creditor claim insolvency bulgaria filing turns on three disciplines: acting quickly on the insolvency opening, assembling an authenticated and reconciled documentary bundle, and valuing the claim correctly under the 2026 euro rules. Foreign creditors should add a notarised power of attorney, certified translations and a trusted local representative to that list. By following the numbered steps, meeting the statutory deadlines set in the opening decision, and citing the official conversion basis in the calculation, creditors give themselves the strongest possible position at verification, at the creditors’ meeting and in the final distribution. For a case-specific assessment, consult a qualified Bulgarian debt-collection and insolvency practitioner before the filing window closes.
