I live in Maryland and my landlord took me to court for payment of back rent. I have since paid the back rent. Everything is now current. He is now saying that he is going to go to the Sheriff's office to have me evicted. Can he do that?

Are you on a lease or a written rental agreement.

But if you are on a month to month rental then they can give you notice to evict.

What are the terms of your lease? Are you a month-to-month tenant or do you have a lease for a specific period of time(6 months, 1 year, etc.)?

Either way, most states require a landlord to provide a tenant 30 days notice. If the tenant does not move after the landlord has asked them to, then the landlord will file for eviction. Has your landlord asked you to move out already or is he simply threatening to have you evicted?
