Now he found out that there's water leaking under his roof near the window area (which is under my floor) and he wants to repair it.
In the beginning he even wanted to compensate me for any related construction (which means open the parquet floor and make a big hole).
But after they had a house meeting with my landlord my landlord agreed on the construction.
(Note that he still hasn't proved that the problem is caused from my apartment).
Finally, today, that downstairs neighbour sent a registered letter (I suppose by his housing agent not by himself) that if I don't agree to the construction I will have to pay all the extra costs and damages, as my landlord agreed, and according to paragraph 184 of the Taiwan Civil Law, which reads:
http://law.moj.gov.tw/Eng/LawClass/LawA ... e=B0000001
A person who, intentionally or negligently, has wrongfully damaged the rights of another is bound to compensate him for any injury arising therefrom. The same rule shall be applied when the injury is done intentionally in a manner against the rules of morals.
He mentioned I should reply within three days. Any suggestions how to react (if at all)?
I really doubt he will sue me in civil court (as he can just repair it from downstairs).
Maybe thats more expensive to do but why should that be on my cost?
