Instructions for Florida Supreme Court Approved Family Law Form 12.905(b), Supplemental Petition for
Modification of Child Support (12/10)
CONTESTED... If the respondent files an answer or an answer and counterpetition, which disagrees
with or denies anything in your supplemental petition, and you are unable to settle the disputed issues,
you should file a Notice for Trial, Florida Supreme Court Approved Family Law Form 12.924, after you

Where can I look for more information?
Before proceeding, you should read “General Information for Self-Represented Litigants” found at the
beginning of these forms. The words that are in “bold underline” in these instructions are defined
there. For further information, see chapter 61, Florida Statutes.
If you do not have the money to pay the filing fee, you may obtain an Application for Determination of
Civil Indigent Status from the clerk, fill it out, and the clerk will determine whether you are eligible to
have filing fees deferred.
With this form, you must also file the following:
Child Support Guidelines Worksheet, Florida Family Law Rules of Procedure Form 12.902(e). (If
you do not know the other party’s income, you may file this worksheet after his or her financial

Settlement Agreement, if you have reached an agreement on any or all of the issues. Although
there is no form for this in these Florida Family Law Forms, you may construct a settlement
agreement using the pertinent sections contained in Marital Settlement Agreement for

one parent may be ordered to pay a portion of his or her support for the child(ren) to the other parent.
Florida has adopted guidelines for determining the amount of child support to be paid. These guidelines
are based on the combined income of both parents and take into account the financial contributions of
both parents. You must file a Family Law Financial Affidavit, Florida Family Law Rules of Procedure
Form 12.902(b) or (c), and the other parent will be required to do the same. From your financial
affidavits, you should be able to calculate the amount of child support that should be paid using the
