Renters legal contract

[Stanley Dean]

Hi All if a tenant in Maryland that signed a 1 year lease contract paid the deposit and half month rent and moves in but her check bounced and I have received not a penny in payments. Do I have to seek legal eviction process or can I bar her from entering the unit and remove her stuff and place at the curb. I believed her to allow her to move in being a teacher and she keeps postponing every week saying she will pay and I have collected no money from her. Please advise.  Thanks
