My Landlord has been harassimg me over rent owed to her and will not extent time for me to pay and there is no rental agreement between us can I sue her for harassment
Your landlord is not harassing you if he/she is asking you to pay the rent you owe. The landlord does not need to extend you time to pay and should being the proceedings to evict you through the Court system. You do not need a rental agreement for you to have a contract. It sounds to me that you have a month-to-month contract and that is a contract, written or not.
Pay your rent.
