The considerations carried out is to confirm the assumption made of the complex nature of trust and its role in social development. First of all, formal and legal entrustment arises when the formal requirements of the legal system are guaranteed – coherence, non-contradiction, differentiation, hierarchy. Secondly, trust in the law arises in the situation of the existence of institutional guarantees of the rule of law and the systemic principle of trust, which is expressed not in retroactivity, correctness of legislation, protection of acquired rights, protection of the so-called interests in progress. Taken together, the fulfilment of these requirements determines the stability of the state of law, the predictability of its application, legality, durability, and, consequently, the ontological security of individuals and social development.
