My sister's daughter was visiting her at her apartment. The daughter's boyfriend came to visit and had an altercation with the daughter when he was refused admittance into the apartment. He shot off a gun outside of the apartment. The police were called. Two days later my sister received an eviction notice. She was given a week to leave for which she did. She received a bill for $1300. Part of that bill was the first month's rent which was waived if she signed a year contract when she first moved in. They went back and billed her for it since she violated her lease. Is that legal? This is keeping her from getting a new apartment. She does not have money to pay this bill.
