In just looking at another question, here is some reference material I pulled from another site On FORMS OF LAND TITLE .
There are two Types of Rights to Private Land
The first is the right of possession (Possessoary right), i.e. people who
possess and use the benefit of land will have the right to possess such
land under the Civil and Commercial Code.
The second is ownership by a person who has a title deed and documents
concerning the land.
Sor. Kor 1
is a notification form of possessed land. There is a certificate to show the
right to the land. This maintains existing rights. Notification of Sor. Kor 1;
on December 1954, the government advised all land proprietors to notify such possession to the government as per form Sor. Kor 1.
After it was proven that such a proprietor had possessed the land legally and used the benefit of the land, then the government would issue Nor. Sor. 3 or Nor. Sor. 3 Gor as evidence. Nor. Sor. 3 and Nor. Sor. 3 Gor are legal
certificates provided that any name shown on the title is a person who has
the right to the land (according to the principle law). This right will be
recognized by the law and can be used as evidence in any dispute with an
ordinary person or the government.
Por. Bor. Tor 6
is evidence by the issuance of a tax number for the purpose of paying tax for using the benefit of the land. Such land has not yet been assessed as to the person's right to possess such land. In the event that there is not title for the land, then it may be land in a conserved forest, public land or land which existed under Sor. Kor 1, Nor. Sor 3, Nor. Sor. 3 Gor or a title deed. Any of these titles must have a Por. Bor. Tor 6 as tax must be paid, the same as any land without a title. Purchase of such land is possible by handing over the possession of the land to the buyer along with the tax nuber. The right to the land under Por. Bor. Tor 6 can not be used as evidence in any dispute with authorities.
Sor. Por. Gor 4-01
is an allotment of land from the land reformative committee, and under no
circumstances may this land be bought or sold. It may be transferred to
heirs only.
Nor. Sor. 3
is an instrument certifying the use of land issued by the government to the
proprietor of land not a possessoary title, i.e. it is confirmed by law that a
person holding Nor. Sor. 3 has the legal right to possess the land. This land
title can be used as a legal document or to use the benefit of the land as an owner. Nor. Sor. 3 is a floating map with no parcel points. It is issued for a specific plot of land and it is not connected to other land plots. This causes problems in verifying the land area. Any legal acts must be publicized for 30 days.
Nor. Sor. 3 Gor
is a legal land title with the same legal basis as Nor. Sor. 3.
The difference being that Nor. Sor. 3 Gor has parcel points on the map, and is set by using an aerial survey to set the points and the land area. It is possible to verify a nearby land area. It always uses the same scale of 1:5000. There is no need to publicize any legal acts, and it is possible to partition (divide) the land into smaller plots.
Land Title Deed (Chanot)
is a certificate for ownership of land. A person having their name shown on
the deed has the legal right to the land, and can use it as evidence to confirm the right to government authorities. The title deed has been issued by using GPS to set the area and boundaries of the land, which is a very accurate method. Any legal acts may be done immediately, as per the right of ownership. Land partition of more than 9 plots must be carried out
according to the Land Allotment Law, Section 286.
