A couple of friends and I were interested in sharing a place. When I was out of HK they found a place and took it as it was a good deal, and they put my name on the contract as the landlord was a bit hesitant, but when they told him that I was working and stable and everything he agreed to lease the place. They paid the first and last, a certain renovation cost, and agent fees; and a friend signed a provisional contract. I would then need to sign the contract when I got back to HK. The problem is there have been some developments and I can no longer stay with them. The contract doesnt have to be terminated, they can get someone to fill my room, but my question is: can I just walk away? All I know is the agent called me and told me the contract is in my name and asked me to come and sign. Does the provisional contract, signed by a friend of mine, hold me to any obligations? Obviously I would need to see the contract, but in general, how does something like this work?
