I have a tenant who rents a residential apartment in New York. There is no written lease. The tenant caused the toilet to be backed up and it overflowed. Tenant called a plumber to fix it. Is the tenant responsible to pay for the repair?
It is hard to answer Choshem Mishpat questions without hearing the other side of the story, but according to what you are saying, that he caused the back up, then he has to pay for it.
