Cell phone contract

I live in Arizona and my stepdaughter signed my husbands name to a contract for a cell phone.She has not paid the bill and now they are calling us for an $1800 phone bill.Do we have any legal rights? since my husband did not sign anything?

Forgery is a felony. Ask cell phone co. for copy of the signed contract and record of the calls and take them to the District Attorney. If your husband thinks that is extreme then try to work out something with his daughter.
