I live in California and I'm thinking of sueing my sister for a student loan I co-signed for her that went into collections. I settled with the collections company and paid with my credit cards and my own money.
There is also another loan with SallieMae that she is always late paying. I know that as the co-signer it is still my responsibility to pay the loans. However, I was thinking of getting a personal loan to pay that off.
If I sue her, my sister has threatened to file for bankruptcy to cancel all her debts. So my questions are this:
Could I sue her for the money I paid out for the settlement and possibly the loan I'm might get to pay off the SallieMae loan? And what is the likelyhood that I would actually win a judgement against her?
I would appreciate any advice. I'm totally lost where to begin and who I can ask for help with this.
