How to tell a "reality' show is fake?

I was a fan of Supreme Justice with Judge Karen till the case of Clara Clayton vs Emmit Brown....watch back to future 3 and you'll see my problem!

The names were clearly fake and sure enough when I looked up her show online I found a small time reality star who'd been on her show and MTV both with different names. He even says he's "portraying a man being sued in the vid posted to his page....big let down.

I was wondering is there a way to easily check and find out if a show is real or not? As far as my research indicates Judge Judy is real, even though the clients are more or less just game show contestants that happen to not like each other. And don't face and real legal trouble win they lose.

But do shows have disclaimers somewhere they say "reenactments" or something like that so we don't waist our time believing this is real human behavior?
