So, there's a lot to this story, but I want to keep it short, so I'll only refer to details which are relevant. I ended my lease agreement in October 2015, during the time we have been in dispute about some things in regards to renovations done to the room which is a question for a different thread. Recently, while looking at my lease renewal agreement, I found 2 mistakes relating to how long the agreement was for. * Lease Period: 13 months * Lease dates: 21/12/2014 - 20/01/2015 To me, this feels like a huge mistake and the lease renewal should be considered voidable. Is this enough? I do feel the estate agent was trying to force a month extra onto the agreement which I hadn't noticed upon signing. Now, I had signed an end of lease agreement, but I'm up in the air if that should be considered voidable too because the dates don't match (20/01/2016 on it). I would appreciate some sources and information on this. Thank you for reading.
