Ok, so while I was at a friend's house a few months the entire supporting wall in her apartment cracked and the builders for the neighbour next door could be seen through the cracks on the other side... This, apart from almost a year of noise that forced my friend and her young baby to stay somewhere else when it became unliveable. The neighbour had no building permit for the work.
The builder was rude but forced his way into her apartment to do a quick cosmetic repair job and said that was sufficient, and the owner came to give her some flowers and cheap bottle of wine. They think that should do it. I got offended at the audacity of these people and felt they took advantage of her (she has difficulty confronting people). I insisted for her to get a surveyor and quotes for a proper repair job and it ended being quite a price tag for a proper repair and reinforcement.
I've now offered to help my friend and demanded the neighbour to pay her for the estimated repairs. The neighbour insist to have her rouge builder do the repairs and refuses to even mention any money. instead, they sidestep my friend and communicate with the building management (whom they have convinced the damages were small and my friend is "difficult" which is not true). I told the neighbour it's not her decision but my friend has the right to chose her own (regular) builders for her property. I'm sure they will refuse to pay. I'm willing to engage a debt collector and involve the council to report the illegal renovations they did on their apartment if she does not pay my friend.
Do I have the right to engage a debt collector if they refuse to pay, without a court order?
Am I being unreasonable?
