I'm not sure. As the AST expires on the 23rd August. I assumed that I had to serve the s21 2 months before the expiry date therefore 23/24 June and I have gone past this date and am now worried.
Then I assumed that I could serve the 2 months notice at any time during the AST provided possession wasn't until after the 23 August. So I thought if I served it tomorrow the 4th July then the 2 months would fall either on the 3/4 sep or 23 Sep
Thank you. Just one last question. If I serve the s21 tomorrow and my tenants decide that they want to remain at the property. would the new AST run from the 23 September and what would happen to the s21 I have served
