My mom let her friend ( ex-wife of her cousin) to use her credit car, the ammount totaled to 49k with the use of credit card, the debtor has an agreement with my mom to pay it in 24months, but sadly my mom lost her job, so she doesnt have now the capability to pay the credit card company. but this only happened recently(my mom not paying the credit card due to her lost job) . there was no instrument with a signature to prove this debt, because it was an act of goodwill from my mom. aside from the owed money from the creditcard, her friend also owes my mom cash of 87,000 from my moms personal money, the debtor now refuse to pay because she says my mom is not paying the credit card, but it was only now that she lost her job, she even refuse to pay the cash money of 87k because she says it was payed due to the money she was paying my mom for the credit card before but my mom was not giving it to the credit card company(recently) can we file a case?
