Ouaoh.. that sucks. If you had a proper contract, you should go to a lawyer... No need to see the guy, what are you going to do? Beat the crap out of him??... Even if you probably feel like to, not the right route.
If you are in a juridiction where lawyers are extremely expensive, try to have them work on a success basis: if they recover your cash, they ll get say 10% of it (depending on what is the absolute amount...)
Good luck
USA. New York. Case is filed in another state where I resides and where they are registered. But I need to serve court documents. I need servers to get in from of this person and that's all. If he refuses at that point - it does not matter - they can put documents on the floor. But, they need to find him
