keeping visitor from primeses

I am liveing with a friend. I had a visitor in our home and the landlord called and told me that my friend was not allowed on property. My friend is going through some legal problems now and the landlord know of what they are. Can the landlord prevent my friend from visiting.

I am a law school graduate. What I offer is mere information, not to be construed as forming an attorney client relationship.

IF this is the situation: you are living with a friend. The friend is the only one on the lease. Then you had a visitor. The landlord said visitor is not allowed on property --> yes.

The landlord CAN prevent this person from coming on private property because your name is not on the lease AND he does not know this particular individual. It would be different if YOU were on the lease, as well.
