tenant has sublet
He let my house to the tenent whom happens to be a estate agent also.
The tenent has now sublet to another person whos name i do not know.
Now the tenent has not paid rent and is refusing to move out.
Apparently the subtenent has a contract with the tenent but i have not seen this.
I also have not signed the orginal AST, apparently the agent had done this on my behalf.
What can i do to evict everyone from my property.
