PROBLEM: Not only do you not have income, the Court won't cut you any slack.
You can't outsmart the system. If you voluntarily quit your job, there is a high likelihood that the Court will simply consider you to be "under" employed. That means the Court will "impute" you an income -- say that you are capable of earning a certain amount -- which typically ends up being the amount of your previous employment. Also, if you voluntarily leave your job, the odds of being able to collect unemployment drop significantly.
SOLUTION: Keep your job, even if you don't like it, at least for now.
You are better off financially if you earn $5,000.00 per month and need to pay $500.00, than earning $0.00 per month and needing to pay $500.00.
We understand that facing a child support or spousal support award can be frustrating and difficult. It's easier to work toward a resolution to those issues with an income, than to face a resolution without an income and no ability to maintain security.
You do not want to find yourself in arrears on a child support or spousal support Judgment because you're jobless. You may end up losing your driver's license, or worse, be found in contempt of court and face severe sanctions.
