Twenty years ago, husband #1 packed it up, left me with our 1 year old kid, a 30 year mortgage and no child support or alimony. To make a LONG story short, I had two choices: feed my kid or pay the bills. Naturally the kid won hands down.
I filed chapter 7, everything was liquidated. The worst part of it was having that on my credit report for TEN YEARS. Sure, you can get credit even with a bankruptcy on your back, but the interest rates are hideous and it's so embarassing when you do try to get new credit!!
The best option is to work through a credit counseling service. They will negotiate lower interest rates and work with your creditors to pay off all your debts in usually 3-5 years. That still causes a hit on your credit report, but not like bankruptcy.
Unfortunately at the time I couldn't even consider credit counseling because of the financial mess the Ex left me in. I can tell you this much though, it was the most humiliating experience of my life. I'm someone that always pays their bills and had excellent credit. Ironically the day I filed for bankruptcy, all my bills were current, but I knew I wouldn't see a cent from the Ex (I was right). The day I had to appear in court, I had to stand before the judge. He all but shook his finger at me and the others standing in front of him when he said "Bankruptcy accepted." and "I don't ever want to see any of you in my (bankruptcy) courtroom again!" Holy $h!t, talk about humiliation.......
Yep, tell your cousin to go the credit counseling route (not to mention getting counseling for his gambling habit)......
