"The tenant" moves out. But he has a sub-tenant who remains. I have no agreement with this sub-tenant. I gave notice to the only tenant of record...and he is leaving tomorrow.
I called the Tenancy Tribunal. They said that the original agreement allows any subtenants to remain until I get an Order they leave from the Tribunal....but that the original tenant (who may have left) remains liable for all the rent until all his sub-tenants also leave.
So I can't kick the sub-tenant out.....but his mate, the (former) tenant remains on the hook for the rent as long as the sub-tenant remains there.
This is interesting stuff.
