Just as the national government, the municipal government is divided into three branches: executive, legislative and judiciary. The judicial branch is administered solely by the Supreme Court of the Philippines. The LGUs have control of the executive and legislative branch.

The executive branch is composed of the governor for the provinces, mayor for the cities and municipalities, and the barangay captain for the barangays. The legislative branch is composed of the Sangguniang Panlalawigan (provincial assembly) for the provinces, Sangguniang Panlungsod (city assembly) for the cities, Sangguniang Bayan (town assembly) for the municipalities, Sangguniang Barangay (barangay council), and the Sangguniang Kabataan for the youth sector.

The seat of government is vested upon the Mayor and other elected officers who hold office at the municipal hall. The Sangguniang Bayan is the center of legislation of the municipality.
