We took over the licence on a hotel because we renovated it at our own expense with some of it paid by the guy who was leasing it by the owner. He was in a commercial lease for 12 months then purchased it at the end of the lease. He got us in to fix it up and then asked us if we wanted to run it. We didn't pay any money for the lease we just got applied for and received the licence for the hotel. After a month or two, the guy that leases it promised to help us financially as we had no money to start up the pub. We now owe thousands of dollars to creditors. This guy started hounding us for rent after a month of opening the doors. We asked him repeatedly for a lease agreement but he still hasn't done anything about it. We have been open for 4 months. He started off by saying to us that he owned the hotel and that the rent will be $2,500 but he will give us 3 months free rent. Then he changed it after a month and started saying that we have to pay him rent because we 'cost him $10,000 a month'. He said we only have to pay 20% of the takings for the week every week up to $2,500. In the last month, he has been constantly hounding my husband (he won't talk to me about it) demanding rent from us, changed it to $3,000 a week, belittles my husband constantly, and has now threatened to evict us because we haven't been keeping up with the rent. We have also learnt that he hasn't paid any rent to the owner of the property that he was in the contract with. The owner wants us to stay here and wants to lease it to us and not sell to the other guy, but it has to be settled by the courts. If the guy comes up with the rent he owes then he can still purchase the hotel, if not then the owner gets to keep it. He will evict us if he gets it. He has led us down the garden path and now we owe money and do not want to leave this pub that we love. What are our rights under commercial law?
