The flat that I plan to buy, it's title was "terbalik" with another unit on the same floor.
Meaning one floor has 5 flats, the flat that I plan to buy is No.14 (2nd unit from left), the title is written No.14, but according to the floor drawing, it should be No.18.
Actual case: All number counted from left to right,
Inside drawing: It counts in zig zag, meaning ground floor and 2nd floor counted from left to right, 1st floor and 3rd floor counted from right to left.
Now they are engaging jurukur tanah and lawyers to settle this issue.
Thanks for the advice. Just called a lawyer and will meet with him soon to discuss about the agreement with current flat owner.
