Before choosing to go to Small Claims, I'd consult your State Bar Association and see if you can get a referral to some legal guidance. A quick
pro bono review may reveal that you have a case that warrants pursuit WITH an Attorney, or verifies that you're wasting your time even going to Small Claims Court.
I feel that if I could get a certified copy of the purchase agreement - and it showed that the items were legally his (buyer from 5 years ago) that I should be able to get at least some of the items back.
Once again, that Contract would only show what the intent of those Parties was at that time . . . . not what was actually transferred. Right now, your best hope is to find the Personal Property itemized in the Deed that was recorded in your local Land Records.
If there's any chance to recover something, then you'll avoid kicking yourself later if you don't take it. This sounds almost impossible because you're needing to prove that the Farmer you bought the stuff from actually owned it . . . . and that person is no longer even helping you to prove it !
Regardless, you have a lot of research to do BEFORE you can go to any Court. Did you get a Bill of Sale at the time you bought this stuff? Did the Farmer make any representations that he actually owned the stuff he sold you? I don't know the validity of it; but people keep repeating that
"Possession is 9/10s of the Law", so if you hear it often enough, it takes on an air of truth, doesn't it ? It doesn't sound like you ever actually took possession of this equipment. Do you have the identity of the Guy who showed up and collected )or re-possessed0 "his" stuff from the Farmer?
Here's an idea. A former Client of mine, who was gypped out of some land, when he bought 89 Acres but received less than 40 Acres . . . . had good luck approaching a Local Law School. 3rd Year Law Students did a really bang up job, under the supervision of their Professor who was a member of the Bar, and they prepared a good Brief for him to go to Court with while suing the Real Estate Agent, the Attorney, the Bank, and the Former Owners in order to be made whole again.
What would have cost him $50,000 was done for less than $10,000 . . . . and he was awarded his damages plus his Court Costs . . . . but he had taken minimal risks along the way. It took only 5 years. In a small community, it's always hard to find an Attorney who will sue another Attorney.
Good luck . . . . you'll need it.
