The key problem in ensuring compliance with international standards for providing legal assistance by lawyers is the inconsistency of legal regulation and practice across countries, as well as insufficient implementation of international norms into national legal systems. This leads to differences in the level of protection of citizens’ rights, limits access to qualified legal assistance, and complicates lawyers’ ability to fulfill their professional duties. An additional problem is the insufficient preparation of some lawyers to apply international legal standards and the absence of unified mechanisms for monitoring the quality of legal services. The aim of the article is to analyze international standards for providing legal assistance, identify problems in their implementation in national legal systems, and develop recommendations for improving mechanisms to ensure the quality of legal services. Special attention is given to harmonizing national norms with international documents, enhancing professional training of lawyers, and ensuring guarantees of independence in legal practice. The study employs comparative, normative-legal, systemic, and analytical methods, as well as an analysis of international documents (United Nations Basic Principles on the Role of Lawyers, European Charter on the Status of Lawyers, and Council of Europe recommendations). These approaches allow for a comprehensive study of standards and an assessment of their application in different jurisdictions. The analysis identified key problems: the inconsistency of national legislation with international standards, the absence of unified criteria for the quality of legal assistance, insufficient protection of lawyers’ independence, and unequal access of citizens to qualified legal services. It was established that effective implementation of international requirements requires comprehensive measures, including legislative reform, expanded professional training of lawyers, and the creation of mechanisms for independent assessment of legal service quality. Addressing these issues will ensure a uniformly high level of legal assistance, strengthen human rights protection, and increase citizens’ trust in the legal system. Harmonization of international and national standards also contributes to the development of the rule of law and enhances the role of the legal profession in ensuring fair justice.
