Abstract
Since 1 January 2016, regulations concerning bankruptcy proceedings have been substantially modified. First of all, the definition of insolvency has been changed and appropriate presumptions that are extremely important from the practical point of view have been introduced. Regulations aimed at speeding up the proceedings, such as the obligation to pay a deposit for the costs of the proceedings when filing a petition or exclusion as a rule of the possibility of allowing expert witness evidence have been adopted. Moreover, the principles for consideration of petitions filed by creditors with disputable claims and the principles of liability of persons obliged to file a petition in bankruptcy for the damage caused by omission thus facilitating assertion of claims by creditors have been regulated.
