had to terminate her lease, then somehow she changed mind, don't

to get the portion, then came to me, the housing case worker said, since changed the owner, I coudn't just write a letter to get the portion, they want me to sign the housing contract, which will let her stay at least one year, so I didn't sign the contract, I told them I need move in. that's why I asked her for full payment.  but she didn't want to pay full payment, she doesn't want  to move out, so she hired a attorney to sue me asked her pay full payment.
