Corporate debt, now personal?

While employed as a treasurer for a corporation, I signed a contract to lease some equipment. About a year later, the corporation dissolved and the equipment was returned. Now, the equipment leasing company is coming after me personally, stating that I signed a personal guarantee and the contract was noncancelable. I don't remember signing a personal guarantee, but it is possible. The leasing company has a terrible rating from various consumer watchdog organizations and I think they are harassing me. This has now appeared on my credit, which prior was perfect. I'm undecided as to weather I should hire an attorney, attempt to fight it on my own, pay the $2800 they want, or just not use credit for 7 years!

Have you asked for a copy of this signed contract? You should find out exactly what they are referring to, and if the equipment was returned, why are they coming after you? Did you sign a contract through your company or through the outside leasing company? Don't forget to dispute it with the credit reporting agencies.

Thanks for your help. I've returned the equipment (credit card terminal), but they still want to get paid through the end of the contract. It was a 5 year contract and we used it for about 1 year. They say it is uncancelable in any circumstance.
I've disputed it on my credit report and haven't heard anything back yet. The original contract was between a private leasing company and my old corporation with me as a personal guarantor. To fulfill the final four years, they want $2800 and I don't think that is fair. I know that AZ is a community property state, so they can't enforce a judgment against me since all of my assets are community assets. Do you think if I continue to stonewall them and fight the credit bureau info, they will eventually give up?
