I agree with John. I would only add that, I would check your credit report to see if in fact they have obtained a default deficiency judgment. If not then they may be more bark than bite. If they have gone to the trouble of getting a judgment agianst you, then you know they mean business. In that case, definitely have someone, or you yourself write up a Settlement Agreement and spell out explicitly that you want ALL negative entries concerning that debt removed from all three credit repositories. Only after having an authorized party on the behalf of the creditor agree to and sign this Agreement, should you give them one red nickle. Once you pay them you loose all leverage.
