I'm pretty sure I was co-signer as we needed one, the company that bought it was the newly formed one not the original we'd bought, but that was in Jan 2002 so I don't know for sure now as I haven't seen the paperwork since 2003. I was a signator for the company when we bought the vehicle and yes, it was a limited corp.
When I dropped it off I was not working for the company had no signing authority or anything. I took the keys in and told them my ex would be in to look after whatever was necessary. And I told my ex I was dropping it off and it was his responsibility to look after as he owned the company. I wasn't about to get into anything else with the company (either of them) or him at that point.
I'd wanted to let the lease go earlier, first when we separated and he wouldn't let me and that was when he told me when the lease was up he'd buy it for me. Then I wanted to let the lease go when I wasn't working and he again talked me out of it saying it would cost too much...so I parked it in my garage and didn't drive it as I couldn't afford insurance.
Stupid I know, I was taken for a big whack with this %%$##%&* SOB!
