Категория разумности в договорном праве

The article examines the category of reasonableness in contract law as one of the fundamental legal principles. Modern civil legislation, along with the requirements of good faith and fairness, emphasizes the need for the conduct of legal subjects to comply with the principle of reasonableness. The author notes that reasonableness is an evaluative concept, granting legal practitioners a certain degree of discretion in interpretation depending on the circumstances of a particular case. Reasonableness is closely connected with the living conditions of society and the individual, reflecting historically established ideas of what is proper and improper. It is emphasized that law provides the normative expression of reasonableness, thereby defining the limits of freedom of contract and ensuring a fair distribution of obligations between the parties. The conclusion highlights the necessity of further developing theoretical and practical criteria of reasonableness in civil law to achieve a balance of interests in contractual relations.
