The relevance of the issues under consideration is mediated by the weak stability of the legal effect of conditional wills due to a number of factors: 1) broad discretion of judicial ex post control in assessing conditions relating to the nature of the heir's behavior; 2) the time required to fulfill the conditions specified in the will, which prevents the timely realization of the rights of the testator's creditors; 3) the lack of effective mechanisms for implementing the conditions, etc.
