hi everyone I need some advice please. Basically a year ago 26th Feb 2016 me and my partner signed a joint tenancy agreement. Before my fixed term was over my letting agents sent me and my partner a renewal in January to sign. I signed but my partner did not neither did we pay the renewal fee either. I then told my letting agents at the end of feb that I actually don’t want to to stay for another year now due to new neighbours moving in and causing trouble next door and due to the fact my partner didn’t sign that I still have the right to leave. The agent then told me that if I give notice to leave I’m liable to pay the rent for a full year (£620 a month)plus remarketing fees for my landlord plus the new tenants fees aswell as the inventory fee to leave and the renewal fee I never paid also I would lose my £750 deposit!!. The agent the new emailed me and said if I pay the £90 renewal fee only then would they call the landlord and tell him I wish to give notice!. They are blackmailing me to stay or I will end charged a huge amount even though my partner didn’t sign the agreement so not all parties agreed to the new contract. They also admitted I had missing paperwork at the beginning as I was never told about renewing or the fees after the 12months plus the renewal was sent in January before the original expired. I feel like my renewal that wasn’t signed by all parties or witnessed either or even paid for isn’t legally binding so I have my rights to leave. But since letting the agents know they have said they would charge me a huge amount if I do. HELP!! What are my rights?
