Abstract
The aim of this paper is to fill the cognitive gap regarding the role of sanctions in the protection of a creditor’s property rights in the event of an entrepreneur insolvency. The impact of sanctions on transaction costs, including their identification and types, as well as the impact on the protection of creditor rights, has been poorly recognized in the subject literature to date. This article investigates the theory of transaction costs and property rights by providing an identification and description of formal negative sanctions, as well as their impact on counteracting the appropriation of creditors’ rights in bankruptcy proceedings. These studies are part of the discussion on the role of formalized negative sanctions, in terms of enforcing behaviours expected by the legislator.
