If you have your own little custom contracts written up, good for you and good luck with them in court. Snap-On credit is the same as any credit company and no, the goods are not "stolen"

. Again its unsecured debt. They want the money and the interest and that's what has transferred to the purchaser, the items purchased are secondary. When you default on credit the credit company never calls you up and says "where are the items purchased on such and such a date, give them to us". Again, unsecured debt.
The credit company never calls and says to give up the product, eh?
You have never defaulted on a note to Snap-On credit, have you? The note that Snap-On enters into between me, and the buyer indicates that the tools are the security for the debt, therefor, it IS a secured note.
If you sell something for which you still owe money and discontinue paying, how do you consider that to not at the very least amount to conversion?
The tools belong to me until the note is paid.
Maybe you should be instructing the guys from whom I have repossessed their tools and boxes that they didn't need to give them back to me.
vary state by state and in most your claim would be thrown out if put to the test. This also assumes someone lets you onto their property to identify your goods and the serial number you recorded hasn't been removed.
Don't get all defensive like im advocating everyone run out and find fresh boxes that have barely been paid for and get them for a song. Im not and personally i'd want to see a completed bill of sale as well just so I know im not going to cause someone like yourself a hard time when you go to collect on a dead beat. I am saying the legal ramifications, should you accidentally find yourself in such a position, are very limited and in no way shape or form should the second party be made out as if they were a criminal.
Regardless of the good faith on the part of the buyer, it money was owed, the product did not belong to the person who sold it and I am able to recover my stuff. I can cite a few instances of buyers who refused to give up stolen goods and were charged with receiving stolen goods and more where the police telling they would be arrested for receiving stolen property was sufficient to allow me to recover stolen property.
Yes, I have consulted legal counsel on this topic just last week to ensure that I do not run afoul of the laws in my attempts to collect.
