INSTRUCTIONS FOR FLORIDA SUPREME COURT APPROVED
FAMILY LAW FORM 12.905(b)
SUPPLEMENTAL PETITION FOR MODIFICATION OF CHILD
SUPPORT (11/15)
When should this form be used?
This form should be used when you are asking the court to change a current court-
ordered child support obligation. The court can change a child support order or
judgment if the judge finds that there has been a substantial change in the
circumstances of the parties and the change is in the child(ren)’s best
interests .
This form should be typed or printed in black ink. After completing this form, you
should sign the form before a notary public or deputy clerk . You should file this
form in the county where the original order was entered. If the order was entered in
another state, or if the child(ren) live(s) in another state, you should speak with an
attorney about where to file this form. You should file the original with the clerk
of the circuit court and keep a copy for your records.
IMPORTANT INFORMATION REGARDING E-FILING
The Florida Rules of Judicial Administration now require that all petitions, pleadings,
and documents be filed electronically except in certain circumstances. Self-
represented litigants may file petitions or other pleadings or documents
electronically; however, they are not required to do so. If you choose to file
your pleadings or other documents electronically, you must do so in accordance
with Florida Rule of Judicial Administration 2.525, and you must follow the
procedures of the judicial circuit in which you file. The rules and procedures
should be carefully read and followed.
What should I do next?
For your case to proceed, you must properly notify the other party in your case of
the supplemental petition . If you know where he or she lives, you should use
personal service . If you absolutely do not know where he or she lives, you may
use constructive service . You may also be able to use constructive service if the
other party resides in another state or country. However, if constructive service is
used, other than granting a divorce, the court may only grant limited relief. For
more information on constructive service, see Notice of Action for Family Cases
with Minor Child(ren) , Florida Supreme Court Approved Family Law Form
12.913(a)(2), and Affidavit of Diligent Search and Inquiry , Florida Family Law
Rules of Procedure Form 12.913(b). If the other party is in the military service of
the United States, additional steps for service may be required. See, for example,
Memorandum for Certificate of Military Service , Florida Supreme Court
Instructions for Florida Supreme Court Approved Family Law Form 12.905(b),
Supplemental Petition for
Modification of Child Support (11/115)
Approved Family Law Form 12.912(a). In sum, the law regarding constructive
service and service on an individual in the military service is very complex and you
may wish to consult an attorney regarding these issues.
If personal service is used, the other party has 20 days to answer after being
served with your supplemental petition. Your case will then generally proceed in
one of the following three ways:
DEFAULT ... If after 20 days, no answer has been filed, you may file a Motion for
Default , Florida Supreme Court Approved Family Law Form 12.922(a), with the
clerk of court. Then, if you have filed all of the required papers, you may call the
clerk, family law intake staf , or judicial assistant to set a final hearing . You
must notify the other party of the hearing by using a Notice of Hearing
(General) , Florida Supreme Court Approved Family Law Form 12.923, or other
appropriate notice of hearing form.
UNCONTESTED ... If the respondent files an answer that agrees with everything
in your supplemental petition or an answer and waiver, and you have complied with
mandatory disclosure and filed all of the required papers, you may call the clerk,
family law intake staf, or judicial assistant to set a final hearing. You must notify
the other party of the hearing by using a Notice of Hearing (General) , Florida
Supreme Court Approved Family Law Form 12.923, or other appropriate notice of
hearing form.
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 have
complied with mandatory disclosure and filed all of the required papers. Some
circuits may require the completion of mediation before a final hearing may be set.
Then you should contact the clerk, family law intake staf, or judicial assistant for
instructions on how to set your case for trial (final hearing). If the respondent files
an answer and counterpetition, you should answer the counterpetition within 20
days using an Answer to Counterpetition , Florida Supreme Court Approved
Family Law Form 12.903(d).
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.
IMPORTANT INFORMATION REGARDING E-SERVICE ELECTION
After the initial service of process of the petition or supplemental petition by the
Sherif or certified process server, the Florida Rules of Judicial Administration now
Instructions for Florida Supreme Court Approved Family Law Form 12.905(b),
Supplemental Petition for
Modification of Child Support (11/115)
require that all documents required or permitted to be served on the other party
must be served by electronic mail (e-mail) except in certain circumstances. You
must strictly comply with the format requirements set forth in the Rules of
Judicial Administration. If you elect to participate in electronic service, which
means serving or receiving pleadings by electronic mail (e-mail), or through the
Florida Courts E-Filing Portal, you must review Florida Rule of Judicial
Administration 2.516. You may find this rule at www.flcourts.org through the link to
the Rules of Judicial Administration provided under either Family Law Forms: Getting
Started, or Rules of Court in the A-Z Topical Index.
SELF-REPRESENTED LITIGANTS MAY SERVE DOCUMENTS BY E-MAIL;
HOWEVER, THEY ARE NOT REQUIRED TO DO SO. If a self-represented litigant
elects to serve and receive documents by e-mail, the procedures must always be
followed once the initial election is made.
To serve and receive documents by e-mail, you must designate your e-mail
addresses by using the Designation of Current Mailing and E-mail Address ,
Florida Supreme Court Approved Family Law Form 12.915, and you must provide
your e-mail address on each form on which your signature appears. Please
CAREFULLY read the rules and instructions for: Certificate of Service (General),
Florida Supreme Court Approved Family Law Form 12.914; Designation of
Current Mailing and E-mail Address , Florida Supreme Court Approved Family
Law Form 12.915; and Florida Rule of Judicial Administration 2.516.
Special notes...
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 afdavit has been served on
you.)
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 Dissolution of
Marriage with Dependent or Minor Child(ren) , Florida Supreme Court
Approved Family Law Form 12.902(f)(1).
Notice of Social Security Number , Florida Supreme Court Approved
Family Law Form 12.902(j), if not previously filed.
Family Law Financial Affidavit, Florida Family Law Rules of
Procedure Form 12.902(b) or (c).
Certificate of Compliance with Mandatory Disclosure, Florida
Instructions for Florida Supreme Court Approved Family Law Form 12.905(b),
Supplemental Petition for
Modification of Child Support (11/115)
Family Law Rules of Procedure Form 12.932. (This must be filed
within 45 days of service of the supplemental petition on the
respondent, if not filed at the time of the supplemental petition,
unless you and the other party have agreed not to exchange these
documents.)
Child Support... The court may order one parent to pay child support to assist
the other parent in meeting the child(ren)’s materia l needs. Both parents are
required to provide financial support , but 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 afdavits,
you should be able to calculate the amount of child support that should be paid
using the Child Support Guidelines Worksheet , Florida Family Law Rules of
Procedure Form 12.902(e). Because the child support guidelines take several
factors into consideration, change over time, and vary from state to state, your
child support obligation may be more or less than that of other people in seemingly
similar situations.
Temporary Relief... If you need temporary relief regarding child support, you may
file a Motion for Temporary Support and Time-Sharing with Dependent or
Minor Child(ren) , Florida Supreme Court Approved Family Law Form 12.947(a).
For more information, see the instructions for that form.
Settlement Agreement... If you and the respondent are able to reach an
agreement on any or all of the issues, you should file a Settlement Agreement.
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 Dissolution of Marriage with Dependent or
Minor Child(ren) , Florida Supreme Court Approved Family Law Form 12.902(f)(1).
Both parties must sign this agreement before a notary public or deputy clerk.
Any issues on which you are unable to agree will be considered contested and
settled by the judge at the final hearing.
Final Judgment Form... These family law forms contain a Supplemental Final
Judgment Modifying Child Support , Florida Supreme Court Approved Family Law
Form 12.993(b), which the judge may use. You should check with the clerk, family
law intake staf, or judicial assistant to see if you need to bring it with you to the
hearing. If so, you should type or print the heading, including the circuit, county,
case number, division, and the parties’ names, and leave the rest blank for the
judge to complete at your hearing or trial.
Nonlawyer... Remember, a person who is NOT an attorney is called a nonlawyer. If
a nonlawyer helps you fill out these forms, that person must give you a copy of a
Disclosure from Nonlawyer , Florida Family Law Rules of Procedure Form
Instructions for Florida Supreme Court Approved Family Law Form 12.905(b),
Supplemental Petition for

the last page of every form he or she helps you complete.
