can i settle with some Credit card companies and not all?

I think you are OK to have a couple of cards with low balances on them. You are paying what you can. I kept my Amex just to have a card if I needed it. Trying to change into a cash only lifestyle.

It is generally not a good idea to keep some of your CC accounts current during the debt settlement process. You can keep 1 or 2 for emergencies but remember that the CC companies can pull your credit report and see that you are paying on other accounts. This could make settlement much more difficult.

Do you have a checking account with any of these creditors? If you do, you need to close that and open a new checking account. Your creditors could access your bank account and take their money.

I would actually disagree with Guest59 on this one. If BOA and Chase see that you're current on even one other card that's going to give them the impression that you can pay them something as well.

Also, don't be surprised if your Amex and Citi cards are eventually cancelled as a result of your plummeting credit score.

This is absolutely true, Ren1000. Your other accounts can be cancelled, even if you have zero balances on some of them, when the creditors see you are defaulting on other cards. OR, your available credit will be lowered to the amount you have on your card, leaving you no room for more charges. I'm in a debt settlement program and both of these things happened to me. I had a few other small cards, like for department stores and gas cards, with low limits that I occasionally use and pay off in full when the bill comes, just to keep them active and keep some good credit in my report, but a few were cancelled/closed, and the one I kept for emergencies lowered my limit drastically. But it's been a blessing in disguise, to learn to live without them.
