Abstract
Actio Pauliana as a form of nullifying a debtor’s legal actions detrimental to their creditors is well recognized when it is used by an individual creditor or the receiver in bankruptcy acting on behalf of their creditors. The article analyses the case of seeking satisfaction (claim) by the creditor or receiver in bankruptcy of the seller against the buyer's bankruptcy assets and before a final court judgment that the act was ineffective. The Polish provisions of the bankruptcy law do not explicitly regulate the manner of dealing with such a claim, so the doctrine and the case law keep on searching for a way to cope with the problem - an example of which is the Supreme Court judgment of 27 March 2019 (V CSK 13/18).
