Abstract
The article addresses the difficult and complicated issue of a legal assessment of neglect by an adult family member of a person vulnerable due to their age or state of health. The analysis carried out in the first part showed that the provisions of the Family and Guardianship Code are indispensable for a criminal law evaluation of such behaviour. Then, the family law regulations were interpreted in terms of the principles of liability envisaged in the Criminal Code. The article pointed to legislative shortcomings of family law that have a certain impact on the application of criminal law.
