Hi. Need advice on evicting a problem tenant please.
He was due to leave on May 7th having been served the correct Section 21 notice etc. He was current in his rent up to this date (albeit paid 30 days late) then said he was not leaving. Can I still use the accelerated process (which states that I'm not claiming arrears at the time of his end of tenancy date), even though by the time it gets to court (due to the current suspension) he will owe rent for the days he has remained there since, which he hasn't paid?
Many thanks
Owen
