Hi, in our ongoing problems with our landlord they are now looking at building ownership. Since we have been tenants for more than 40 years now and we have built all the modern farm building on the farm with either the landlord or his mother our previous land lady permission. The trouble is as we had a excellent relationship with there things were always done over a cup of tea and verbal permission was always given. Now the landlord has new agents and they are trying to get use our of the farm. They have asked to see all written permission for building the sheds which we don't have. It is in the tenancy that if we have built without written permission it is breaking the tenancy. The last shed was erected 21years ago and there has never been an issue until now. The last 5 rent increases have also been do verbally and he has quite happily excepted this so should this show that everything has been do verbally or do we not have a leg to stand on?
