Well it looks like mods don't want anybody to know my experience with open titles.
If the name state printed on the title is not same as person that is selling what indication do you have the seller is owner? Anybody that can convince a judge the trailer belongs to them will take the trailer.
And for the idea "hold the last of the money"; You pay 10%, hold 90. What reason does "owner" have to do the paperwork? Sure, he doesn't get the 90% FROM YOU But he can get 10% from a dozen others, still have trailer
