It's possible to verify a nearby land area. 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.
Legal acts are unlimited.
A suggestion for foreigners is to lease the land for 30 years with an option to an extension of the lease, then purchase ownership of the house built on the land. Certainty of possession of land and house is assured, by being the owner of the house. The ownership of the land shall be leased out. If arranged as stated above, then the house will be separate from the land, and will not be a component part under the Civil Law. Ownership of buildings can be confirmed, and the lessor cannot seize the house upon expiration the lease.
