Creation of Lawigan Municipality, Iloilo

The boundary between Lawigan and San Joaquin begins at the mouth of the Tiolas River.
The boundary follows the Tiolas River upstream to the Quianan bridge at barrio Pitogo.
It then continues along the Iloilo-Antique inter-provincial road to the provincial boundary at barrio Dawis.
The boundary description is based on a sketch plan or map prepared by the District Engineer of Iloilo, with a scale of 1:8000.
After segregation, San Joaquin retains its original territory minus the areas comprising Lawigan.

Lawigan shall come into official existence only after:
- Appointment and qualification of its local officials: mayor, vice-mayor, and a majority of councilors.
- Certification from the Secretary of Finance affirming Lawigan's financial capacity to enforce the Minimum Wage Law and fulfill all statutory obligations and essential municipal services.
- Certification that the mother municipality, San Joaquin, remains financially capable of maintaining municipal governance, meeting obligations, and providing essential services despite the territorial reduction.

The creation is pursuant to section sixty-eight of the Revised Administrative Code.
The Executive Order was signed by the President of the Philippines and countersigned by the Executive Secretary.
It was promulgated in Manila on July 10, 1961, formalizing the establishment of Lawigan as an independent municipality.
