Dear "can my landlord refuse rent money before eviction notice":
No, the landlord must deliver the notice first if he later plans to begin an eviction lawsuit.
Your defense is that you tendered the rent to him but he sent it back.
Keep the message. Keep your bank statements, receipts, etc., handy.
Put the money aside so it is available.
See a local lawyer if you are unsure or if you want to go over your lease agreement and your options.
Ok, you did not get an eviction notice. Did you get any other type of written notice? Perhaps written notice of default, notice to cure, lease termination or lease violation? Did your lease term expire? Do you have a written lease agreement? Without proper lease termination and notice, a landlord generally cannot refuse to accept your lease payment. Consult with an experienced landlord-tenant attorney.
Any response does not create an attorney - client relationship without both parties fully signing a representation agreement.
