The Iranian Law and Legal Research Institute (Persian: پژوهشکده حقوق و قانون ایران), formerly Allameh Legal Encyclopedia Research Center (Persian: مرکز پژوهشی دانشنامه‌های حقوقی علامه), is a scientific and juridical research institute, composed of four groups: encyclopedia writing, legal theorization and intellectualism, studies on social impact of laws, and studies on "extra" laws.

Operating under the license of the Ministry of Science, Research and Technology of Iran, this research institute is one of the first legal entities to be recognized as a knowledge-based company by the Vice-Presidency for Science and Technology of Iran.

Reviewing and analysis of bill drafts, guidelines and bylaws, as well as creating a framework for writing legal encyclopedias in more than 60 disciplines are among the activities of the institute.

A group of people who have a background in judicial and managership work founded the Iranian Law & Legal Research Institute in 2010 under Judiciary Vice President for Education and Research for Judiciary, focusing on the collection and management of peripheral legal knowledge.

[5] With its research record conducted in 2020, the Iranian Law and Legal Investigation Institute was one of the first scientific centers to have received the Vice President of the Science and Technology title of knowledge-based enterprise.

The management body comprises the Research Board, the Vice Presidency of Research, the Vice Presidency of Sustainability and Technology, the Inspector, the advisory committee and Public Relations.

[14] Another publication of this research institute, which received publishing authorization from the Press Supervisory Board in September 2011, is Biweekly of Law and legal information courier.

[15] There have been numerous activities and achievements by the Iranian Law and Legal Research Institute to this day.

These include 15 volumes of jurisprudential documentaries on civil law,[16] a compilation of legal terms of 106288 words,[17] translations of the Tahreero Al-Majalleh five-volume collection,[18] and numerous bibliographies and sources of information.

The project identified, collected, and organized peripheral knowledge of legal materials in collaboration with about 200 researchers who are judges, lawyers, faculty members, graduates, and law students.

The bill proposed for a project was drawn up based on "Civilian Registry Evaluation" and "Civilian Registration Law Amending and Review" research projects in 62 sections, 37 notes and 78 X and is currently being prepared in the hands of the committee with over 12 sub-projects for evaluation of the necessities.

The research then started with the assumption that "every area of study with a history of the definition of more than ÷0 specific subjects in special works will require that a specialist encyclopedia is developed as an independent area of law research."

The research institute has many times assessed and analyzed draft bills, guidelines and bylaws.
