This article is devoted to problems of interpretation in law, including methods of interpretation. The general nature of rules, inability to specify it absolutely all specific life situation is an objective reason for interpretation. The question of how to interpret law is important in the doctrine of interpretation. They give us an idea of the mechanism and tools for such activities. Under the method of interpretation in legal literature understand specific techniques and knowledge of the rules necessary to clarify the interpretation of the subject real content of legal norms. It should be noted that among the scientists are still not developed a common approach to determining the specific methods and rules clarify the law, their union in ways of interpretation. The author of the article considers the grammatical, logical, systematic, historical interpretation and their application in law. The grammatical way (verbal, philology, literal, the lexical – variants of the name) the most common. The logical interpretation – an interpretation of a legal act on its contents using the laws of logic. The existence of systemic predetermined systematic interpretation of law. Interpretation of the individual acts in law, including contracts made by the same means. When using systematic interpretation be accounted into other parts of the contract, with the provisions of the law, and the use of historical – documents the parties prior to its conclusion. Consequently the competent authorities that carry out law enforcement activities is not entitled to refuse the dispute through obscurity legal standard. There are no clearly defined rules of these methods. They can be used all at once or can be selected for one or more individual discretion, depending on the possibility of achieving the objective interpretation. Thus if the grammatical and logical interpretation repelled from the texts themselves, the systematic and historical methods rely on elements external to them. Disclaimer enforcer of the whole gamut resulting in a one-sided application of the law. The interpretation is based on the premise that the system of law should be free from contradictions and each provision should be in harmony with the whole system.
