What you need to do is retain a family law attorney to assist you with respect to the issues that you still have with your former wife and monies that you owe her as the result of the marital dissolution proceeding and final judgment that you have written about.Your disposable earning are the monthly amount that you receive from all sources of income. Typically the net disposable earning are all costs that you have on a monthly basis subtracted from your monthly disposable earnings.The non-exempt disposable earnings would be your salary, accrued interest on bank accounts, stock dividends and the like excluding social security payments and other sources of income that your state of residence does not include in disposable earnings.Good luck.
