You should consult with a Florida attorney to discuss your case in detail. However, generally, a child support obligation is fixed in a dollar amount set at the time of a hearing. The judge sets the obligation based upon a finding of your income at the time. Unless there is a dramatic and/or unforeseen change in circumstances, the obligation isn't changed.
Whether you work one or two jobs should have been taken into account at the time of the initial determination.
In Florida, child support is based on income from ALL sources so both jobs are counted.
