My friend and his parents rent a house (for his parents) + granny flat (for himself) on a single lease. In the rental agreement, there is clause says that tenants pay for water. He told landlord that he will arrange electricity and water bill payment between him and his parents. For example, he pays for water for both main house + granny flat and his parents pay for electricity for both main house + granny flat. A few weeks later, he asked the landlord if he can pay rents separately from his parents (say $500/week splits into $350/week from his parents and $150/week from him). The landlord agreed. Now here comes to an interesting part. The standard NSW rental agreement says unless electricity and water are separated metred, tenants do not need to pay for electricity/water. Now he doesn't pay water usage to his landlord (even after repeated request from the landlord) and he asks landlord to pay for electricity bills. He deliberately pays rent late. His landlord is going to take him to court. He retaliated by saying that he is going to ask the landlord to pay him back the huge electricity bill because he legally does not need to pay it. I am wondering, will he succeed with his evil plot?
