Same thing. The cautions can be placed on everything without evidence like a lien, just file a document.

Deals can be made while awaiting the court case as long as both parties know about the lien.
Que said this but may not have been clear.
I have purchased about ten things with cautions.
Unlike Que who is sure he has a case, the cautions I ignored were without merit.

In each case the caution was dismissed when I refused to settle out of court.
The person who filed the cautions got tired of spending on lawyers, or the lawyers who took a percent instead of cash knew they could not win and abandoned the guy.
