You need to win a judgement in civil court first and try to collect on it before you can attach a lien to someone’s house in almost any jurisdiction in the US.
Not hard? Not easy to prove fraud. Is it fraud to have multiple jobs? Did your employment contract specifically restrict moonlighting? Is it even legal to restrict moonlighting in that state? Plus, even if all the moons align and you go through all that effort and money and possibly win. They declare bankruptcy and protect their homestead from your claim. You lose even more money and most importantly your time. Far from easy.
