Utah  |  Credit and Debt Law

I want to Garnish a person's pay, pursuant to a judgment. The instructions (Utah) say to first "verify that the garnishee employs the debtor," otherwise I may be liable for up to $1000 to the garnishee. I know for sure the Garnishee works at the business since she owns it (a franchise). Is it still necessary? Giving advance notice (i.e., the verification letter) will allow the garnishee to avoid paying by deferring income. Garnishee's pay is by commission.
