1. You simply get an instalment order against the debtor and provide notice of it to the employer. the employer will then be obliged to direct part of the judgment debtor's salary to you from the source. This is how you deal with this issue of the intransigent debtor. You can also get details of the bank account into which the salary gets paid and attach any monies there by way of garnishee.
2. Discovery in Aid of Execution can also help you if you believe that the judgment debtor has other assets. I would recommend you get an order for Discovery in Aid of execution anyway just to put the judgment debtor under pressure.
