How do I go about finding where someone is employed? This person owes me a sum of money. He was ordered by the courts to pay or be in contemp. In order for him to either be picked up or ordered to pay we need to find where he works. Can you help

No, in order for him to be ordered to pay or to be picked up, you need to know where he lives.
In order to garnish his wages you need to know where he works.

Can you not just take him back for contempt ? Have the court order him to tell you where he works ?

But you hire a PI to follow him and/o to search records and find where he words.
