Asked tenant to move out and gave her notice she got a lawyer

[Dinali W.]

Hello All,

My tenant has refused to pay rent and after repeatedly giving her notice to pay I asked her to leave. She then began accusing me of things I did not do. She said there was a mold infestation in the laundry room, which there was months ago but I took care of it. She is also claiming that there is a bug problem, I have two other tenants but this is the first I am hearing of this. She is also claiming that I have not been a good landlord and have been cursing her in front of her granddaughter. Which I did not. 

She has brought a lawyer in and I just received that official letter. She signed a lease until March 2018 and the letter the lawyer sent is saying that I have no legal right to kick her out. But she's not paying...

She also got the county involved and had them do an inspection which I am not worried about. But now because she didnt pay rent which led to me asking her to leave I had to pay for a lawyer and other expenses. 

What do you advise I do? Am I in the wrong here?
