Discuss your facts fully with an experienced local family law attorney. There aren't enough facts given here to offer a helpful response.
If this answer is helpful or the best answer, please say so. Legal disclaimer: In accordance with the Avvo community guidelines, this communication does not constitute "legal advice", nor does it form an attorney-client relationship.
The answer to this question will depend on a number of factors an attorney will need to know: How long ago was the previous order entered? Where? What kind of order (administrative, judicial)? What income figures were used to calculate the current support amount? How were those numbers derived (actual income, imputed income)? You should consult an attorney and bring all the paperwork you have concerning the support proceeding.
A lot more information will be needed to know what child support should be. You should consult with an attorney in private and they can calculate it for you.
