United Nations Office of Legal Affairs
The United Nations Office of Legal Affairs (OLA) serves as the central legal authority for the United Nations. Established on February 13, 1946, this secretariat office provides essential legal services to the UN Secretariat and its various principal organs, ensuring that the organization operates within a consistent legal framework while contributing to the evolution of global law.
Currently led by Under-Secretary-General Elinor Hammarskjöld, the OLA is headquartered in New York City. Its primary mission is to support the progressive development and codification—the process of arranging laws into a systematic code—of both international public and trade law.

The Management of International Treaties
One of the most critical functions of the OLA is its role as the custodian of international agreements. Through the Treaty Section, the office discharges the depositary functions of the Secretary-General for more than 560 multilateral treaties. This involves the custody of original documents and the formal receipt of signatures and instruments of ratification or accession.
Pursuant to Article 102 of the UN Charter, the OLA is responsible for the registration and publication of all international treaties and agreements. This ensures transparency in global diplomacy. Once a treaty is adopted, it must follow official UN legal procedures—including signature, ratification, and entry into force—as administered by the OLA.
