The legislator has not included an explanation of the definition of gross ingratitude in any legal act. The author focuses on the analysis of decisions that show what kind of behavior can be considered gross ingratitude. In the paper, the author discusses situations in which the legal durability of a donation contract can be interrupted and emphasizes that not every behavior is a reason for revoking a donation. The author points out that the lack of a legal definition of the concept of gross ingratitude leaves many inaccuracies, as one can encounter divergent rulings in similar factual situations.
