Surely the whole point is that it's not at your own cost. That's why it's for small claims only. You could just raise another case if he didn't pay. BTW it's a Sheriff in Scotland, not a judge.
On the other hand Maimie, I raised one a few years back. It costs you nowt apart from the fee which was about £35 (and refundable if you win) and the guy gave in a couple of days before he was due in court.
Back when i looked into it.....you would make a claim for what it was you were disputing, and then you added costs into the equation. But i was suprised too....as i thought part of the service included would be recovery of the debt...but it wasnt, you would have to cover the initial cost of that and add it to your bill. As i say, back when i looked into raising a case, It was explained that you were basically paying for the Sherriff to make a judgement...that was all
Also, the defender doesnt even have to turn up to the court...its not obligitory, but in that case, the Sherriff will most likely make a judgement against them. I ended up writing off the £600 we were ripped off....as i knew, and the defendant knew...i didnt have the money to recover the debts....even tho i would technically claimed it back. Basically, I was relying on the fear factor of taking the guy to court. He was well versed in ripping people off, and knew he was likely to get away with it.
