First, I want to congratulate IAAL on such an eloquent reply. Though, if everyone paid their debts and creditors didn't get judgments, I would have to get a legitimate job.
Now, since you seem so intent on being a 'dead-beat', I just want to understand your basis:
1) You, in a desire to get the 'better things' in life, applied for a credit card.
2) In that application process, you agreed (PROMISED!) that, in return for borrowing someone else's money (doesn't matter if it is MasterCard or your parents), you would repay that money plus an agreed interest. And your repayment would be in accordance with an agreed schedule.
3) Now that you have obtained the things that you wanted, you have decided to 'stiff' the lender.
I believe that if someone did that to you, after loaning them money, you would probably be pretty upset and call them all kinds of things, like; scum-bag, low-life, sleazy, liar, cheater, etc.
Also, I think you would make every effort to get your money back, including taking that scum-bag to court.
However, that low-life scum-bag decides to cry and whine and file for bankruptcy, figuring "Hey, ain't such a bad deal, and ain't life grand that I can do this bankruptcy thing?".
So, here is what will happen to you. You will get a major 'hicky' (bankruptcy) on your credit history. That lasts 10 years. You will also get a 'hit' on your credit history for the bad debt. And you might even get a 'hit' for the judgment. That will mean that ANYONE (lender, potential employer, insurance, even girlfriend) that can get your credit report will see what you are. Additionally, I figure that with all that, your credit rating might be in the mid-500's, this will probably raise your interest rate one or two points from any lender FOR THE NEXT SEVEN TO TEN YEARS. That in alone might even cost you more than any negotiated settlement.
So, yea, just go ahead, make my day!
