Republic Act No. 10023, also known as the "Free Patent Act," governs the issuance of free patents for the administration of public lands in the Philippines. Its implementing rules and regulations establish the procedures for applying for free patents, including eligibility requirements, documentation needed, and the process for surveying and titling lands. The law aims to provide security of tenure and promote land ownership among the underprivileged and landless citizens, facilitating equitable access to land resources. The Land Management Bureau oversees the implementation, ensuring compliance with the provisions set forth in the law.
