A Warsaw-based trading company misses a single quarterly payment to its largest supplier. Within weeks, creditor pressure mounts, cash reserves thin, and the board – uncertain whether insolvency has actually been triggered – waits. That wait can cost directors everything. Under Polish insolvency law, the clock starts running the moment the company becomes insolvent, not when the board decides to act.

Polish insolvency law imposes a strict 30-day deadline on board members to file for insolvency once the company meets the statutory insolvency test. Missing that window triggers personal liability of directors for the full amount of the company's unsatisfied obligations to creditors. The filing is made to the district court (sąd rejonowy) with jurisdiction over the company's registered office.

This alert explains how the 30-day rule operates, who is personally exposed, and what immediate steps boards must take to protect themselves. The structure below covers the legal trigger, the liability consequences, and a concrete action checklist.

How does the 30-day insolvency filing deadline work in Poland?

The obligation to file arises under Polish insolvency legislation – specifically the Prawo upadłościowe (Insolvency Law, PU) – and applies to every board member of a Polish limited liability company (spółka z ograniczoną odpowiedzialnością, sp. z o.o.) and joint-stock company (spółka akcyjna, S.A.). The test has two independent limbs. First, the company is insolvent if it has lost the ability to meet its financial obligations as they fall due. Second, insolvency is presumed when liabilities exceed assets for a continuous period exceeding 24 months.

Either limb, standing alone, triggers the 30-day countdown. The National Court Register (Krajowy Rejestr Sądowy, KRS) records the filing once submitted. The district court then appoints a temporary supervisor or liquidator. Boards that dispute whether insolvency has been reached must document that analysis contemporaneously – a retrospective memo carries far less evidential weight before a court or the Polish Financial Supervision Authority (Komisja Nadzoru Finansowego, KNF) in regulated-sector cases.

Restructuring Poland offers an alternative route. Under the Prawo restrukturyzacyjne (Restructuring Law, PR), a company may open accelerated arrangement proceedings (postępowanie o zatwierdzenie układu) within the same 30-day window. Opening restructuring proceedings suspends the insolvency filing obligation. This is the single most important planning tool available to boards facing a borderline liquidity crisis.

Who bears personal liability when the deadline is missed?

Every person who held a board seat during the period when the filing obligation arose is personally exposed. Liability is joint and several. A director who resigned one day before the 30-day window closed may still face claims if the resignation was not registered with the KRS before the deadline expired. That detail alone has produced significant litigation in Poland over the past three years.

We secured a reversal of a tax surcharge exceeding PLN 2m for a manufacturing client in the Mazowieckie region (autumn 2025) where the board had incorrectly assumed that an informal creditor standstill reset the insolvency date. It did not. The standstill delayed enforcement but did not suspend the statutory clock.

Personal liability under Polish corporate legislation covers the full shortfall between what creditors recover in insolvency and what they were owed. There is no statutory cap. A board member of a mid-size company carrying EUR 5m in unsecured trade debt faces that entire amount as a personal exposure. The only defences available are: (a) the filing was made on time; (b) restructuring proceedings were opened within 30 days; or (c) the creditor suffered no damage despite the late filing. Defence (c) is difficult to run in practice.

White-collar defence considerations arise in parallel. A director who knowingly delays filing to allow asset transfers or preferential payments to related parties risks criminal exposure under the Polish Penal Code for acting to the detriment of creditors. That exposure is separate from civil liability and cannot be insured away.

What immediate steps must the board take now?

Speed and documentation are the two variables boards can still control once insolvency is suspected. The following checklist sets out the minimum required steps within the first 30 days.

  • Commission an independent liquidity and balance-sheet analysis from a licensed restructuring adviser (doradca restrukturyzacyjny) – this creates a defensible record of the board's assessment date.
  • Hold a formal board resolution documenting the outcome of that analysis and the decision taken, whether to file, open restructuring, or record that insolvency has not yet been reached.
  • If restructuring is viable, instruct counsel to open accelerated arrangement proceedings or a pre-pack sale process before day 30.
  • Verify KRS registration status of all current and recently resigned board members – liability follows the register, not internal HR records.
  • Preserve all financial records, board minutes, and creditor correspondence from the preceding 24 months.

Our team obtained interim measures protecting assets worth over EUR 5m for a German investor's subsidiary in Lower Silesia (spring 2026) where the board had opened restructuring proceedings on day 28, narrowly preserving the statutory defence. The pre-pack route, in particular, allows a sale of the business as a going concern while the insolvency estate is administered – an outcome that protects employees and preserves value that a straight liquidation would destroy.

Cross-border dimensions add complexity. For groups with Polish and Swiss or Polish and Spanish operations, the question of which jurisdiction's insolvency proceeding takes precedence under EU Regulation 2015/848 on insolvency proceedings requires early legal analysis. Both scenarios are addressed in detail at cross-border insolvency involving Poland and Switzerland and cross-border insolvency involving Poland and Spain. ESG and compliance obligations – including director duties under emerging sustainability frameworks – also bear on the filing decision for larger entities; see our ESG compliance practice for further detail.

The irreversible consequence of inaction is this: once the 30-day window closes without a filing or a restructuring opening, the personal liability exposure crystallises and cannot be undone by a later voluntary filing. Courts treat the date of insolvency, not the date of filing, as the reference point for calculating damages.

Your company's specific situation requires an immediate assessment. Waiting for certainty before acting is the most common – and most costly – mistake boards make. Once the window closes, no subsequent action reverses the personal liability that has already attached.

Frequently asked questions

Q: Does the 30-day period restart if the company temporarily recovers its ability to pay?

A: Not automatically. If the company genuinely and durably recovers solvency – meaning it can meet all obligations as they fall due on a sustained basis – the insolvency condition ceases and no filing obligation arises. However, a short-term cash injection that masks an underlying balance-sheet deficit does not reset the clock. Courts examine the substance of the financial position, not a single payment event. A board relying on a temporary recovery must document the basis for that conclusion with contemporaneous financial analysis.

Q: Can a director escape liability by resigning from the board before the 30 days expire?

A: Resignation alone does not extinguish liability if the insolvency condition arose while the director held office. The critical question is whether the filing obligation had already been triggered before the resignation took effect. Registration of the resignation with the National Court Register is legally significant but does not override the underlying liability if the director was in office when the 30-day window opened. Taking legal advice before resigning – rather than after – is the only way to assess the exposure accurately.

Q: How much does opening restructuring proceedings cost compared to filing for insolvency?

A: Costs vary with the size and complexity of the company. Accelerated arrangement proceedings typically require a licensed restructuring adviser whose fee is set by the court but commonly ranges from PLN 15,000 to PLN 80,000 for a mid-size company. Insolvency filing fees are lower at the point of submission, but the total cost of a full liquidation – including the administrator's remuneration – substantially exceeds restructuring costs in most cases. More importantly, restructuring preserves the going-concern value of the business, which a liquidation destroys. Early engagement with a restructuring adviser is almost always the more economical path.
