RE: Purchased used trailer w/ no title
some states don't issue titles for trailers
here in NJ you need a bill of sale with the make ,model,serial # and it has to be signed by the previous owner and also notarized along with the copy of registration
there' is a company somewhere that will aquire a tittle for you I think they charge $75 I know someone who uses them to aquire car titles
I can find out for you if you need it
