Florida Form 12.905(a): Supplemental Petition to Modify Parental Responsibility, Visitation, or Parenting Plan/Time-Sharing Schedule and Other Relief

Start with the free official Form 12.905(a)

Florida Courts currently lists Florida Supreme Court Approved Family Law Form 12.905(a), revised November 2015. The official PDF contains eight pages: five instruction pages followed by the three-page petition.

What the official packet says the petition addresses

The packet says this form may be used to ask the court to change current parental responsibility, visitation, and/or a Parenting Plan or time-sharing schedule. Its instructions state that a determination or plan may not be modified without showing a substantial, material, and unanticipated change in circumstances and a determination that modification is in the children's best interests.

What information appears on Form 12.905(a)?

1. Match the existing case caption

The petition begins with the judicial circuit, county, case number, division, petitioner, and respondent. It also asks for the full legal name of the person making the petition.

Use the existing court record to identify factual caption information. This guide does not decide party labels, venue, jurisdiction, or where a petition should be filed.

2. Identify the current order without interpreting it

Paragraph 1 displays choices for a final judgment of dissolution of marriage or paternity, asks for its date, and states that a copy of the judgment and later modifications is attached. Paragraph 2 asks for the paragraph numbers describing the current parental-responsibility, visitation, Parenting Plan, or time-sharing arrangement and whether those terms appear in the final judgment or the most recent modification.

These fields record what existing documents say. This guide does not identify the controlling order, interpret an order, resolve conflicts among orders, or decide what must be attached.

3. Treat the three narrative sections as legal-content boundaries

The petition contains separate spaces for: the claimed substantial, material, and unanticipated change in circumstances; the requested modification; and why the requested change is asserted to be in the children's best interests.

4. Read the child-support choice as a printed choice

Paragraph 6 asks the filer to indicate whether a modification of child support is requested. This guide identifies that choice but does not recommend an answer, calculate support, or determine whether a support change is available or required.

If support modification is requested, the instruction packet lists additional documents, including a Child Support Guidelines Worksheet and financial materials. The packet's list is not a case-specific determination of what any individual must file.

5. Check the companion-form statements against the official packet

The instruction packet identifies Form 12.902(d), Uniform Child Custody Jurisdiction and Enforcement Act Affidavit, and a proposed Parenting Plan—Form 12.995(a) or 12.995(b)—among the documents discussed with this petition. It also references Form 12.902(j), Notice of Social Security Number, if one was not previously filed. Financial-affidavit, guidelines-worksheet, and mandatory-disclosure materials are discussed when child-support modification is sought.

Those are statements from the official 2015 packet. Procedures and local requirements can change, and this guide does not select companion forms or determine which documents a particular case requires.

6. Keep Social Security numbers out of this petition

Paragraph 10 refers to the separate Form 12.902(j), Notice of Social Security Number, if it was not previously filed. Form 12.905(a) does not display a blank for a Social Security number.

This public guide does not request or collect Social Security numbers. Review official confidential-information instructions and current court procedures before handling protected identifiers.

7. Review the oath, signature, and notarization block separately

The final page contains an oath concerning the truthfulness of the petition, a warning about knowingly making a false statement, the petitioner's date and signature, contact information, designated email addresses, and a notary-public or deputy-clerk block.

Completing a PDF does not sign it, administer an oath, notarize it, file it, serve it, or turn it into a court order. Read the official execution language before signing and obtain qualified help if its consequences are unclear.

8. Read the 2015 procedural instructions in current context

The packet discusses filing, e-filing, service, response timing, default, uncontested and contested proceedings, hearings, mediation, parenting courses, and related forms. Those passages describe the official packet, but statewide and local procedures can change.

Florida Courts' current self-help guidance ↗ says self-represented parties are responsible for current statewide rules, local rules, administrative orders, required documents, and deadlines. Court self-help personnel may provide permitted administrative and procedural information, but they do not act as a filer's lawyer.

Nonlawyer assistance has a separate disclosure block

The packet says a nonlawyer who helps complete the form must provide Form 12.900(a), Disclosure from Nonlawyer, before helping and must place identifying information at the bottom of the last page. Form 12.905(a) includes those blanks below the notarization section.
