i offered a lease to a girl who signed lease but never gave me money. we decided to move into home instead of leasing it. we never received money from the renter so we told her home was unavailable. we never provided her copy of lease as no money had been exchanged, she is now threatening to sue us, but she has no copy of a lease, we shredded it, and she never gave us any downpayment. should we be worried? can she sue us for breach of contract if she 1) never had a copy of lease and 2) never gave us a security deposit or rent? I hate being threatened. She really has nothing from us in writing...please help.
