Local villagers turned out to support one claimant and blocked land survey work by the Phuket Land Office (PLO) last Friday (December 9).
Authorities are investigating which of the two Sor Kor 1 certificates, issued to acknowledge legal occupation, is fake, and whether officials were involved in issuing the initial land title papers illegally.
Resident Adisak Pleekarn arranged a surveyor from the PLO last Friday to survey the 15 rai of land that he claimed was his.
But the survey was blocked by villagers who supported the other claimant, Toenjai Toawong, who said the 8.5 rai belonging to her had been wrongfully included in the 15 rai being claimed by Mr Adisak.
Both Mr Adisak and Ms Toenjai could both produce land documents showing their possession rights, surprisingly holding the same Sor Kor 1 certificate of ownership.
The case will be further investigated by the Phuket Provincial Land Office.
