I have a legal issue that I do not know how to solve.
I have a tenants in one of the flats who I had no previous issues with. The rent is paid on time and there were no complaints about them. However, last week they have ordered a new couch which was promptly delivered to the flat. The delivery team acted a bit clumsy and there were some damage done on the staircase: peeled paint and peeled wood from the railing. This is nothing major but it is visible and requires renovations.
The problem is the tenants think I should cover the costs as an owner or no one at all. They claim it was not their fault, it was the delivery and either they should pay for it or myself. Where as I find them responsible. How to solve this and what can I do?
