They can file a small claims lawsuit if the amount owed is less than $7500. They are not entitled to attorneys fees in small claims, although they will be entitled to interest at the legal rate of 10%. Pay them what you can afford. Even a small claims judgment will provide for affordable monthly payments.

Make them an offer for repayment you can live with. If that is not acceptable to them, tell them, they can go through the cost of a lawsuit and get a judgment for the same amount you are already agreeing to pay back and still be faced with the same issue, how are you going to pay it? Most reasonable people will work with you. If they want to be unreasonable, there is nothing you can do about it.
