Do you mean can you be evicted?
Are you in the middle of an AST?
Assured shorthold tenancy agreement.
OK but are you currently on an AST? If so, when does it end?
In that case, you are on a periodic tenancy agreement and the landlord can serve a S21 notice at any time.
He has to give you no less than two months notice on or before the date of the rent date. However, if that is done correctly then the S21 is valid and you can be evicted.
He cannot just turn up and change the locks though. He will need a court order to put you out of the house.
Can I clarify anything for you?
Yes, your circumstances are not the problem of the landlord I'm afraid.
