Por Bor Tor 5 meaning :A land with a possessory right has never been substantiated by Department, but is only recognized by tax payments at the Local Administrative Office. It means that a person is the "possessor", pays taxes, but the real owner is the government. Slowly, the government is changing these old title deeds into Chanotte..or Nor Sor Sam, where the owner of the land is the REAL owner, and the land is clearly delimitated. On possessory rights, you can't register rights like usufruct or a lease. Also you can't get a building permit but it's very common for Thai people to build houses on these Title Deeds without any building permits. Examples of possessory rights are Por Bor Tor or Sor Kor. A land with this type of Title Deed will have much lesser value than a land with a Nor Sor Sam or Chanotte.
