It looks like a very basic informal document that she put together herself for convenience sake. I doubt if she took legal advice about it but I don't know for sure.
I dont know what entitled AST means. It isn't mentioned on the contract.
It hasn't been defined as such by either of us. It was initially for a 2 month period with a potential to be extended.
Does the fact that she texted an acceptance to a 3 month extension last Friday have any bearing on the case? She has since said that she made this provisional to Barclaysdefinitely extending the contract. But as thats not been confirmed she was entitled to re let the room. Well its 99% certain the contract will be extended next week.
Also her texted acceptance wasn't made provisional she has added that later to cover herself.
Not really. If its an AST then it needs to be in signed writing. If its a periodic then she can break that at any time by serving a S21 notice upon you. But please note that she does have to use a proper S21 and she has to give you no less than 2 months notice and she hasn't done that.
