Automatic Calculation of Arrears of Protected Earnings 
Scenario
Suppose a court order for child support against an employee specifies that £30 should be deducted from the employee's earnings monthly. His protected earnings are £1,000. In one month his attachable earnings were only £900 and in the following month his attachable earnings were £1,500.
The payroll then calculates as follows:
Month 1

£1,000 |
Court order |
£30 |
Attachable earnings |
£900 |
Deduction |
NIL |
Arrears of order |

Month 2
Protected earnings: |
£1,100 |
Court order plus arrears |
£60 |
Attachable earnings |
£1,500 |
Deduction |
£60 |
Arrears of order |
