FAQ

Frequently asked questions

Does buying a house mean buying land?

The structure must be confirmed, especially for foreign buyers.

Is inspection enough?

No. It does not replace title, access or permit review.

Can a fence prove the boundary?

No. Fences may not match the official record.

What if an extension lacks documents?

Obtain qualified review before proceeding.

Should access be registered?

Practical access alone may not provide a secure legal right.
